Title: Improvements in the manufacture of articles from rubber, rubber-like or other plastic materials
IPC: B29C70/68
Filed: 1956-02-27
Abstract: A printing roller is made by applying to a rotating or stationary former a heat-curable <PICT:0849480/IV(a)/1> viscous rubber, rubber-like or plastic material and heating the material by passing an electric current therethrough or through an electric heating element associated therewith.  The element may be wound spirally around the material, or be embedded therein, or contained within a cavity in the former.  In the apparatus shown, a former 25 wound with an electric heating coil 20 is mounted for rotation by a motor driven belt 23.  Whilst the former 25 is rotated the viscous coating material is poured on to the coil 20 either manually or from a hopper traversable along the length of the core.  The thickness of the coating is determined by a wiper roller 29 which is driven frictionally by discs 34, 35 mounted near the ends of the former 25. The discs 34, 35 are detachable and interchangeable with others for varying the spacing between the former 20 and the roller 29, and thus the thickness of the coating 19.  Adhesion of the material to the wiper roller is inhibited by applying to its surface a liquid such as water, gum arabic, or oil by a belt driven absorbent damping roller 30.  When the coating 19 has been applied it is vulcanized or cured by feeding electric current to the coil 20 through brushes 42 and slip rings 39.

Filed: 1944-03-31
Abstract: 577,713. Wireless signalling; pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1944, No. 6069. Convention date, Jan. 12, 1943. [Class 40 (v)] Generation of frequency-stable, high power, narrow pulses of rapid build-up is attained by generating a frequency-stable, broad pulsed carrier wave, amplifying said carrier wave and simultaneously keying this carrier wave in response to narrow pulses synchronized to occur within the period of greatest amplitude of the broad pulses. In the example shown, a high " Q " oscillator 10, in this example normally blocked, feeds a high-frequency amplifier or frequency multiplier 12 whose output is connected through a low " Q " amplifier 14 to aerial A. A broad pulse generator 16 is used to unblock the unit 12 and in the example shown also unblocks oscillator 10. The amplifier 14 is also fed with short synchronized pulses from pulse generator 16, but an inverse arrangement may be employed, or both sets of pulses may be derived from pulses of intermediate length. The resulting pulses may be time-modulated either by modulator 20 associated with source 16 of the broad pulses or with the pulse shaper 18. The carrier amplifier 14 is normally blocked by a negative bias on its grid, and is opened by each short positive pulse applied to its anode and grid (Fig. 2, not shown).

Abstract: 1436472 Receivers MOTOROLA Inc 11 Feb 1974 [1 March 1973] 06144/74 Headings H3T and H4L [Also in Division G4] A receiver designed to respond to the sequential application of at least two tones A, B comprises means for suppressing an output therefrom if tone B is received within a predetermined time after reception of tone A. Thus substantially simultaneous detection of tones due to shocking, jarring or other external influence on the receiver is ignored, and the receiver may safely use reed filters. Reception of tone A by filter 14 gives rise to a negative pulse which is differentiated at 31; if tone B is detected while 31 is still providing a negative poutput, then gate 32 is enabled. Latch 33 then operates to keep gate 32 open for the duration of the output from filter 15, while the output from gate 32 operates an inhibitor 21. In the embodiment of Fig. 3 the outputs from 14, 15 are applied to terminals 35, 51, the signal at 35 being differentiated at 36 to turn transistor 37 off. If a signal is applied to 51 while 37 is off, then transistor 50 is turned on, transistor tor 37 is clamped off and transistor 55 is turned on. The voltage at terminal 56 is then applied to inhibitor 21.

Abstract: 1,135,763. Thermal switches. MORPHYRICHARDS Ltd. 3 Feb., 1966 [13 Feb., 1965], No. 6322/65. Heading H1N. The temperature at which a bimetallic strip switches off an electric toaster is automatically varied in dependence upon the temperature of the strip at the start of each toasting operation by means of a variable coupling between the strip and a switch-operating lever, the coupling being reset each time an operation is initiated. A bi-metallic strip 2 fixed at one end to the frame 1 is connected at its other end to pull a rod 5 to the right as the strip 2 is heated. The rod 5 passes freely through a slot (Fig. 2, not shown) in the upper end of a lever 9 which has a stepped portion 11. Toasting is initiated by depression of a spring-loaded member 6, mechanically connected to a switch and carriage for the toast (neither shown), until it is held by the latch 7. A member 13, linked to member 6 (Fig. 9, not shown), allows rod 5 to fall to the bottom of the slot (shown by a broken line). At a temperature predetermined by an adjustable cam 10 the nut 12 engages step 11 on lever 9 to tilt latch 7 and release member 6 to terminate the toasting, while member 13 lifts the rod 5 to the position shown. If a second operation is started while the toaster is still hot the rod 5 will be more to the right and nut 12 will rest on top of step 11 (as in Fig. 7, not shown), thus necessitating a higher temperature of strip 2 before the nut moves lever 9 to release member 6. The stepped portion 11 may consist of several steps in echelon.
