Title: A programming apparatus for controlling the operation of an appliance
Inventor: TILLOUX JEAN ANDRE HENRI
IPC: G04C23/16
Filed: 1967-12-04
Abstract: 1,212,364. Valves. JAEGER. 4 Dec., 1967 [31 March, 1967], No. 54968/67. Heading F2V. [Also in Division H1] Programme control apparatus for starting and stopping an appliance at preset times and which can also be used for manual control has a rotary knob 21 which is movable either way from an off position to provide manual or automatic control respectively, and when axially depressed returns immediately to its off position. The embodiment described actuates electrical contacts by a rotary cam 27, but it is stated that the stem of a fluid-control valve may be actuated instead of contacts. Rotation of knob 21 in either direction turns a spindle 26 via gears 23, 24, 25, and a portion 57 of a member 47 secured thereon stresses a coil spring 53 which thus tends to restore the spindle 26 to its neutral position. A latching member 45 on spindle 26 is free to tilt by virtue of the bevel 55 but is angularly coupled to member 47 by means of fingers 46 thereon. When knob 21 is turned to its " manual " position (MAN, Fig. 1, not shown), member 45 latches behind a ramp (54, Fig. 5, not shown) on a fixed plate 42, and spindle 26 is restrained in angular position wherein a cam 27 on the end thereof acts on a follower 28a to displace a spindle 28 against spring 35 and holds movable contacts 30, 31 in bridging engagement with fixed contacts 32, 33. When knob 21 is turned to " automatic running" (AR) member 45 latches behind a timing spindle (60, Fig. 6, not shown) and the contacts are maintained in the open condition. At the " on " time (preset by a spindle 20, Figs. 1 and 6, not shown), timing mechanism driven by a synchronous motor (2, Fig. 2, not shown) causes spindle (60) to be withdrawn and member 45 moves into latching engagement with another timing spindle (59)-the consequent rotation of spindle 26 closing the contacts 30, 31, 32, 33 and causing knob 21 to rotate to an " automatic" (AUT) position. When spindle (59) is withdrawn at the " off " time (preset by reverse rotation of the spindle 20) the member 45 is released, spindle 26 is fully restored and the contacts are opened. If knob 21 is set to " automatic " (AUT) the contacts are immediately closed and opened, as above, at the preset " off " time. In the " manual " (MAN), " automatic " (AUT) or " automatic running " (AR) positions of knob 21, depression of the knob (against spring 44) pivots a lever 39 about pin 40 and causes a collar 58 to tilt the member 45, thereby releasing it from its respective latched position and immediately restoring the knob 21, spindle 26 and contacts 30, 31, 32, 33 to the " off" condition. Details of a time-drive uni-directional rotation mechanism (Figs. 2 and 3, not shown), and an alarm contact (75, Fig. 7, not shown) independently settable by a knob (72, Fig. 1, not shown) are also disclosed.

Abstract: 1285974 Magnetic storage apparatus FUJITSU Ltd 14 Nov 1969 [16 Nov 1968] 55981/69 Heading H3B [Also in Division H1] In order to suppress noise due to half select drive current pulses in a magnetic memory an inductor, the inductance of which is high for half select currents and low for full select currents, is connected in each drive line. The inductors 22 each comprise a conductor covered with ferromagnetic material and are held in spaced parallel arrangement by an insulator. Word lines W1-W9 of a plated wire memory M, Fig 1, are driven by coincident current core matrix C1-C9. In order to suppress noise produced in the memory wires M due to current pulses on the word lines W1-W9 as a result of a half-select current pulse partially switching an unselected core C1-C9 a plurality of inductors 22 are connected to the word line strips W1- W9, Fig. 9A, coupling the switching cores C1- C9 and memory wires M. Thus the small current induced in a word line by the associated partially switched core C1-C9 encounters a high impedance in the word line and are not effective whereas the current due to the full select switching of core C1-C9 encounters a low impedance. The switching cores are held in notches in the side of insulating plate 21 on which is mounted a strip of insulating material, Fig. 10A (not shown), carrying the inductors 22, thereby facilitating their connection to the word line strips. The inductors can be cylindrical, Fig. 5A (not shown), or in the form of strips, Fig. 5B (not shown), and are formed into strips by a laminating process, Figs. 11A, 11B (not shown), the spacing between the elements corresponding to that of the word lines W1- W9.

Abstract: 1419124 Vibratory conveyers INTERNATIONAL COMBUSTION AUSTRALIA Ltd 8 Dec 1972 [9 Dec 1971] 56741/72 Heading B8A [Also in Division F2] A vibratory feeder, e.g. for use in a vibratory feeding and screening apparatus, comprises a feeder trough 4 having a material pan 5 to the underside of which are attached two transversely spaced longitudinal walls 7. Mounted between the walls 7 at an angle other than 90 degrees to the horizontal is a vibratory mechanism 8 having a mounting 9. A vertical dividing wall 13 having a plurality of spaced holes 14 is mounted between the floor 10 and roof 11 of the mounting 9 and secured to walls 7. The holes 14 are surrounded by spring retainer cups 15 and receive spacer tubes 16 which are smaller in diameter than the holes 14. Retaining plates 17, 18 are attached to the spacer tubes 16 by tie bolts 19. Two helical steel springs 20 are mounted on each tube 16, one on each side of wall 13 and one end of each spring is positioned in the cups 15 on the wall 13 and their opposite ends positioned in similar cups on the retaining plates 17, 18. The springs are retained under partial static compression. The retaining plate 17 incorporates a mount 21 to which a motor 22 driving an eccentric mass is attached. A weight assembly 23 is attached to the plate 17 to ensure a correct vibratory motion. Additionally, if required, a balance weight assembly 25 may be attached to the plate 18. In use the steel springs 20 serve as both the pivot of a pendulum and the spring elements in a resonant spring-mass combination. With the motor running the mechanism 8 is caused to vibrate about a transverse axis of the mounting 9 and, with the feeder resiliently mounted, will transmit vibrations to the trough 4 in a longitudinal direction only thus causing material placed in the pan 5 to be fed in the required direction. The motor itself moves in an unimpeded pendulum action about the above transverse axis. The geometrical configuration of the springs 20 is such that their lateral action or rate has no effect on the operation of the mechanism other than to isolate the drive means from the feeder in the vertical direction. This is achieved by utilizing a spring array in which the springs have a low lateral rate. Thus, as the motor moves in the vertical direction the forces imparted by the eccentric mass in that direction have little or no effect on the feeder while the forces applied in the longitudinal direction of the springs are such that the amplitude of the vibrations imparted to the feeder is greater than it would be if the springs were replaced by, for example, a pendulum pivot. Accordingly a straight line motion is imparted to the mounting 9 and thereby to the pan 5 in the feed direction to achieve or more efficient feed rate.

The mercury-amalgam-containing assembly for a low pressure mercury vapour lamp disclosed in the parent Specification is modified to prevent leakage of molten amalgam from the cut ends of the assembly. In one method, a series of separate strips of indium is pressed into a single, broader strip of nickel mesh by passage between a pair of rollers, of which that contacting the indium is of nylon, and is provided with a pair of spaced knife-edges which make recurring cuts in the indium strip to define short indium-free lengths of the subassembly which subsequently provide margins at the cut edges of the completed assembly similar to those along its longitudinal edges. The strips of indium between the outs are removed by the roller itself, or by compressed air, gravity, or bending the sub-assembly at the strips and using a suitable tool. Thereafter the sub-assembly is pressed into either a similar sub-assembly, or a continuous nickel mesh, whereafter the separate assemblies are produced by cutting through the indium-free regions. Alternatively, the cut ends of the assemblies produced by the method described in the parent Specification may be oxidized by the use of an intense flame or by resistance heating, the indium and nickel oxides thereby produced preventing outward migration of the amalgam. A thicker amalgam-containing structure may be produced by pressing together a plurality of the assemblies to form a stock.
