Title: Improvements in electric circuit breaker
IPC: H01H71/74
Filed: 1961-09-13
Abstract: 994,364. Automatic circuit-breakers. GENERAL ELECTRIC CO. Sept. 13, 1961 [Sept. 15, 1960], No. 32847/61. Heading H2B. The setting of an electromagnetic trip device of a circuit-breaker is controlled by an adjustable armature back-stop or biasing spring which is coupled to a control member or knob by a lever system including a member which is movable to alter the setting range and which in one of the extreme positions of the backstop or spring can be moved without moving the back-stop or spring. As shown, the releasable trip arm 13 of the circuit-breaker is held by an intermediate latch 44 retained by a lever 43 and latch member 41 in engagement with a retaining cam 40 on a three-phase trip-bar 38 pivoted at 39 and biased by a spring 47. The armature assembly 27, which has a projection 37 for operating the trip-bar 38, cooperates with poles 21 of a U-shaped magnetic frame 20 and is pivoted at 29 and biased against the back-stop screw 66 by a spring 32. The stop 66 is adjustably mounted at the end of a lever 58 pivoted at 60 and having at its other end 61 a screw 62 threaded in a barrel 63 biased away from the end 61 by a spring 62. A spring 65 acts on the lever 58 to bias the barrel 63 against a second lever 57 pivoted at 59 and engaging a setting screw 67. The latter can be adjusted to the Fig. 4 position in which the lever 58 engages a stop 52 and the levers 58, 57 are parallel. In this position the backstop screw 66 and a screw 35 controlling the spring 32 can be adjusted to the required minimum trip setting. Subsequent adjustment of the screw 62 to move the barrel 63 toward or away from the lever end 61 will increase or decrease the range of trip setting provided by adjustment of the screw 67 but the minimum setting remains unchanged since the levers 58 57 are parallel at this setting. The independent setting may be the maximum setting with the stop 52 in the dotted position above the lever 58. A mark on the trip mechanism casing 51 may indicate the parallel position and the stop 52 may be omitted. A bi-metal 26 attached to the through conductor 17 also acts on the trip-bar 38. In Fig. 9 (not shown), the free end of the lever 58 receives an adjustable coupling for the fixed end for an armature biasing spring and the adjustable armature back-stop is mounted on a fixed part of the circuitbreaker.

Title: Improvements in horizontal boring, drilling and milling machines and other machine tools
IPC: B23Q5/56
Filed: 1954-11-18
Abstract: 773,620. Boring, facing and milling machines; machine-tool details. NEW BRITAIN MACHINE CO. Nov. 18, 1954 [Nov. 23, 1953], No. 33422/54. Class 83 (3). A machine-tool comprises a movable element to be accurately positioned on a support, first and second screw-threaded-members respectively associated with the movable and support members, and force-applying means operatively connected to one of the elements and to the threaded-member associated therewith for applying to the latter a force tending to disengage the thread-surfaces for relieving the movable element from forces tending to cause any additional movement. The invention may be applied to the cross-slide feed-means of a horizontal boring, facing and milling-machine. The cross-slide F, Fig. 3, is moved by a screw 18 rotated by gearing 21 and mounted in the saddle E in bearings 19, 20. A nut 22 secured to the cross-slide co-operates with the screw for feed. A cover 24 passes through a bracket 23 carrying the nut and protects the screw. At the completion of a feed-movement of the slide to the right by a limit-switch (not shown), which declutches the drive from a feed and rapidtraverse motor, an open switch is closed to actuate a solenoid for admitting air to a piston- and-cylinder 26. The latter operates a yoke 28 pivoted to the saddle at 32 and pads on the yoke bear on a thrust race 36 and collar 37 on the end of the lead screw to exert a pull thereon. The force exerted is of sufficient magnitude to overcome any tendency of axial-forces in the bearings 19, 20, due to loading caused by the positioning of the table, to move the screw axially. and upset the initial positioning of the table. A similar arrangement may be applied to the feed-screw for the vertically sliding boring-head.

Title: Improvements in or relating to colour sorting machines
Inventor: FRAENKEL HERBERT
IPC: B07C5/342
Filed: 1958-10-20
Abstract: 885,283. Photo-electric sorting apparatus. GUNSON (SEEDS) Ltd., R. R. Dec. 11, 1958 [Oct. 20, 1958], No. 33485/58. Class 40(3). In an apparatus for sorting articles according to colour the articles are radiated by light and viewed against backgrounds by a plurality of photo-electric means which receive light from the articles and the backgrounds from a corresponding number of different directions. The backgrounds are so supported that their positions may be simultaneously adjusted. The photo-electric outputs control means for separating desired from uridesired objects. Each photo-electric means may be sensitive either to light of one colour only or to light in two distinct parts of the spectrum. The light may be polarized and infra-red may be used to. detect the presence of an article in the inspection area.  When inspecting an object by detection of light in two parts of the spectrum the apparatus of Fig. 1 is used. Objects 2 pass through the frame-- 3 from a conveyer 1 and light received from the objects passes through a lens system and slot 10 to photocells 4, 5 by way of light-conducting member 12 (see also Specification 885,287). Filters 6, 7 select the two parts of the spectrum. The photocells feed a difference amplifier 14 which in turn feeds a comparator 15 which distinguishes desired from undesired objects (see Specification 885,287) and controls an ejector 16, e.g. an air jet device, Fig. 7 (not shown),, which ejects faulty articles. The frame 3, Fig. 2, comprises a square inspection area through which fall the objects 2, the objects being illuminated by indirect visible light from lamps 25-28, and, via filters 21, by infra-red. Coloured interchangeable backgrounds 22 are supported on carriers and shielded by shields 24 from direct light from adjacent lamps. The backgrounds and carriers are all linked together so that by movement of arm 31 the distance of each background from the object 2 may be varied so that the intensity of the reflection is also varied. Alternatively, each background comprises a cylinder rotatably mounted on a shaft, the cylinder being coloured in different areas with varying amounts of the colours in which sorting is to take place. If the objects to be sorted show a high degree of specular reflection they are irradiated with polarised light, Fig. 4 (not shown), and only diffuse light from the objects is detected by the photo-cell system, (see Specification 885,266). Specification 885,285 also is referred to.

Patent GB-638111-A (GB)
Title: Frequency-responsive electric system
IPC: H03D3/24
Filed: 1947-12-22
Abstract: 638,111. Frequency measurement. HAZELTINE CORPORATION. Dec. 22, 1947, No. 33841. Convention date, Jan. 4. [Class 37] [Also in Group XL (c)] In a discriminator system for detecting and indicating frequency deviations, the input wave is periodically applied to shock-excite a resonator (tuned circuit, piezo-electric crystal, &c) and after a predetermined interval, the damped wave set up in the resonator is compared in phase with the input wave. The output of the phase comparator is a measure of the frequency deviation, and may be applied to the signal-reproducer of a F.M. receiver, or to a frequency meter. As shown, the input wave A, Fig. 2, to the discriminator 23, Fig. 3, is the output of the intermediate-frequency amplifier 22 of a F.M. radio receiver, and is applied to the grid of a normally inoperative class C amplifier 12. When the amplifier is rendered operative by a short positive pulse B, Fig. 2, from the source 13<1>, the peaks of one or more waves excite the tuned anode circuit 10 and set up therein a damped wave C, Fig. 2, the frequency of which operates as a standard or reference frequency, and is applied to the inner control grid 29 of a mixing valve 15<1>. This grid is also back biassed so that anode current flows at the wave peaks only when a short positive pulse D, Fig. 2, delayed by the coil 33, is applied. The input wave from the amplifier 22 is also applied to the grid of a valve 14<1> and is converted therein to a saw-tooth wave by virtue of the resistor 39 and condenser 38 in the anode circuit. The saw-tooth wave is applied to the outer control grid 40 of the mixer valve 15<1>. When the input wave deviates in frequency, the reference wave peaks applied to the inner grid vary in their phase relation with the saw-tooth input to the outer grid, so that the current pulses through the valve 15<1> vary in amplitude in linear relation with the frequency deviation. These pulses may be integrated in the condenser 34, and the signal thus obtained passed to an audio amplifier 24 and reproducer 25. The delayed signal from the pulse source 131 may alternatively be applied to the valve 14<1> operating as a class C amplifier, and the valve 40 may be replaced by any suitable phase-comparing device (Fig. 1, not shown), the output of which may control a frequency meter.
