    • 651,109. Time-alarm signals. GREIN, P. F. A. Nov. 16, 1948, No. 29793. [Class 118 (ii)] An interval timer comprises a normal clock mechanism 1 driving a minute-spindle 5 to which an arm 6 is frictionally coupled to co-operate with the member 12 and constitute electric alarm contacts. The position of member 12 is controlled by knob 10 and indicating pointer 9 mounted on the front panel 7 of the device. The knob 16 operates a control switch in circuit with contacts 6, 12 and an alarm device 13, such as a buzzer, and battery 18 (Fig. 1, not shown), and also serves to start and stop the balance-wheel 17 by means of the springy arm 19 when turned to " On " or " Off " respectively. To use the device the pointer 9 is first returned to zero by means of knob 10, the member 12 thereby setting arm 6 to zero position, and then the pointer is set to the required time interval and the control knob 16 put to " On." This starts the clock movement and arm 6 advances until it contacts member 12, when it is arrested and the electric alarm is operated until knob 16 is restored to " Off." In the modification of Figs. 4-6 (not shown), the pointer assembly is directly coupled to the advancing arm and member 12 is replaced by a fixed electric contact on the front panel. After setting to the required time interval and switching the control knob to " On " the arm and pointer are driven back to zero where the arm is arrested by the fixed contact and thereby sounds the alarm. The alarm may be visible instead of audible, and the device may be operated from the electric mains in place of the battery.

    • 650,953. Linear-dimension gauges. TOYNBEE, W. F., and GREIN, P. F. A. Nov. 12, 1947, No. 30121. [Class 106 (ii)] Apparatus for determining the thickness of hair comprises hair gripping feeler elements, the.opening of which sets an indicator working over a scale to indicate directly the grade (i.e. fine, coarse or the like) of a hair being measured, and a platform having means by which a hair may be held and guided between the elements. To permit the insertion of a hair to be gauged, a rod 4 is manually pushed to the left, when a tapered portion 4a thereof allows a feeler 12 to fall under the action of a spring 14. The hair is guided and held between the feeler 12 and an adjustable feeler 11, by a loop, eye or spring clip 20, so that when the rod 4 is released, its movement under the action of a spring 15 is limited by the feeler 12. The corresponding grade is then indicated by a sprung pointer 5 which is engaged by a stud 17 in the rod 4 and which co-operates with a scale 8. The rod 4 may be operated by means of a pistol grip and may position the pointer through a rack-andpinion. Furthermore, the taper on the rod may be replaced by a cam and the indicator may move linearly. Alternatively, the rod 4 may be replaced by a lever system.

    • 549,786. Hair-waving appliances. GREIN, P. F. A., and ALEXANDER & CO., Ltd., C. March 3, 1942. No. 2798. [Class 131] A protector pad for hair waving apparatus comprises a pair of channel shaped metal arms 1, 2 carrying rubber coverings 3, 4 the arms being hinged at 5 and provided at the other end with a fastening member 8 hinged to one member and engaging hooks 9 carried by the other. The member 8 is resiliently attached to the arm 2 by hinging it to a metal strip 12 engaged by a leaf spring 14 both being retained in the channel of the arm 2 by a rivet 13. In order that the rubber covering 3 of the arm 2 may be separable without removing the fastening it is formed with a base 16 having an upstanding part 17 with a projecting rib 18 engaging the channel of the arm. The other covering may be similarly formed or as shown comprise a sleeve 4. The covering 4 is stepepd at 19 to interengage the part 16 of an adjoining pad. Standards 20, 21 for supporting a curler are arranged so that the axis of the curler is offset from the meeting line of the rubber parts 3, 4.
