Title: Improvements in clockwork timepieces associated with means for indicating expiry of pre-selected time intervals
IPC: G04F3/02
Filed: 1948-11-16
Abstract: 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.

Abstract: 1,215,648. Extruding; compressing scrap. DOW CHEMICAL CO. 24 June, 1968, No. 30060/68. Headings B3H and B3P. [Also in Divisions C6-C7] A charge of particulate magnesium-base or aluminium-base alloy is compact extruded in a die by a punch, a proportion of the particles of the charge having a length to thickness ratio of at least two. The charge amy be compacted prior to extruding in a separate container or in an extrusion die mounted on a turret movable from under the compacting punch to a position under the extruding punch. The particles are formed by mechanical reduction of an ingot by machining or by jet atomization or disc atomization. The particles are shaped in a rotating ball mill or paint shaker containing steel balls or alumina cylinders. The contents are separated with a coarse screen and graded by an inclined table so that the spherical particles are rolled away from the elongated ones. The elongated particles may be flattened in a rolling mill. The aluminium alloy is normally compressed at room temperature whereas the magnesium alloy may be compressed hot or cold. For both alloys the extrusion is performed on a hot compact into a cylindrical can by backward extrusion.
