Abstract: 1,239,308. Measuring displacements electrically. CROSS CO. July 18, 1968. [Sept. 15, 1967 No. 34391/68. Heading G1N. [Also in Divisions G4-6] In apparatus for measuring the deviation from truth of a rotating mechanism, a sensing probe is applied to be displaced by the deviation and caused to generate a signal the maximum and minimum values of which are detected to derive an average value, and in a subsequent rotation the recurrence of the average signal is indicated. The probe is connected to the armature of a differential transformer 12 the output amplitude of which is proportional to the displacement of the probe. The signal is rectified at 50 to produce a D. C. voltage varying from -3 to +3 volts. The output on line 58 is applied to a maximum amplitude detector 56 where it is stored as a signal on a capacitor. A minimum amplitude detector 60 also receives the signal on lead 62 and stores the lowest value. Resistors 82, 84 connected to the maximum and minimum stores provide an average value signal at 86. This is applied to comparator relays 122, 124 where it is compared with the output signal from the sensing circuit so that in a subsequent rotation these comparators respond when the average value is reached, one when it is reached from the low side and the other when it is reached from the high side. A control device may be energized to stop the mechanism in these positions. The outputs for the minimum and maximum stores are also applied to comparator relays 136, 138 to obtain a signal indicating the total deviation. This may be recorded and displayed. The average signal is applied to a bank of threshold relays arranged in pairs 96-114. The relays are differently biased, and the relays of each pair are differently biased to indicate in decimal form the average deviation. This is converted to a form suitable for display on a bar-lamp indicator and may be used to select suitable shims to take up the average out-oftruth of the mechanism under test.

[Also in Division H1] Electrical contact to a region of one conductivity type defining an electro-optically active junction in a body of the opposite conductivity type is achieved by means of a pin mounted in a bore passing into the region from a planar face of the body, the pin extending out of the body at the face. The device may be a photovoltaic detector or a photo-emissive diode or laser. The light emission or reception occurs at a second planar face so that the light path is not blocked by the contact to the region. An N-type body 23<SP>1</SP> contains an array of devices 22 each comprising a P-type region 27 contacted by a pin 28 which is a tight fit in a bore 25 to provide a pressure contact, Fig. 5. In modifications the pin extends to the top surface of the wafer where it is provided with a head of such dimensions that the light path is not blocked, Fig. 6 (not shown), a headed pin is soldered into the bore, Fig. 7 (not shown), and a wire is soldered in the bore, Fig. 8 (not shown). The PN junction shape may be inverted relative to that shown or may comprise a straight cylinder, Fig. 17 (not shown), and the bore may extend halfway only through the body, Figs. 9b and d (not shown). If the pin is provided with a head this may be of transparent material. The junction may be so arranged that the light is emitted from the edge of the body, Fig. 18 (not shown). The devices are made by forming the bore in the body by masking and etching or by electron beam drilling, and then photomasking and diffusing to form the region surrounding the bore. The starting body may comprise an epitaxial layer on a substrate of the same conductivity type. The surface through which the light passes may be lapped or polished to improve the light transmission and the face through which the contact pins extend may be coated with an opaque material such as beryllium oxide or boron nitride. The semi-conductor material may be GaAs, or GaAlAs utilizing Te and Zn as the N- and P-type impurities.

Abstract: 1290661 Rotary conveyers MOLINS MACHINE CO Ltd and K G REEVES 2 Oct 1969 [3 July 1968] 31636/68 Heading B8A A packet 9 of cigarettes carried between the pivoted plates 22 of a rotary delivery mechanism is transferred to a holder 7 carried by a rotary conveyer 1. The members 22 are caused to diverge by engagement of a cam follower 23 with a cam 24. The holder 7 comprises members 7a, 7b, which are caused to move together by engagement of roller 16 with cam 18 not shown. The packet carried by the holder is carried round and at the same time rotated, so that at B it assumes a horizontal position and is then guided by rotating members 52 on to rotating platforms 53 which discharge the packet on to a stack S. The packets are discharged from the stack S horizontally two at a time beneath a roller 71 by air jets 66, 67, and are then discharged by an endless belt 69. Level detectors 61, 62, operate to cut off the air supply when there are less than 4 packets in the stack S. Should the level of stack S rise too high, then platforms 53 as they rotate, engage and contact the top packet, and the pivoting movement of the platforms causes the holder members 7a, 7b not to discharge their packet. The packet 9 on the holder then passes position B and is discharged later. The drive to the rotary conveyer 1 (Fig. 3) comprises a driving shaft 29 which drives the sun-wheel 3 through gears 35, 37 and shaft 39, and drives the rotary conveyer 1 which rotatably carries the holders 7, their gears 36 and 44, the gear 2 which carries each holder engaging the sun-wheel 3 so that each holder has two circular movements.

The sheets are then registered against lay stops 19, Figs. 1 and 5, of a sheet processing machine, by means of driven rollers 22 carried by the stops 19, and then when the stops 19 rise are separated and fed to the machine, in a direction at right-angles to the first feed direction. Sheets not to be separated yet are held back by intermediate stops 25. Air is blown through a duct 15, Fig. 3, of the device X in the direction of feed, and causes underlapping of the sheets. For overlapping, the air flow is in the opposite direction, Fig. 4. When there is a break in the feed to the processing machine, the stops 18 are lowered to allow sheets to pass on to an auxiliary pile 24<SP>1</SP>, or else the conveyer 7 is swung downwards to deposit them on an auxiliary pile 24. According as the sheets are underlapped or overlapped, the rollers 22 may be above or below the sheet path.

Abstract: 1295886 Targets BRUNSWICK CORP 2 Feb 1970 [14 Feb 1969] 4825/70 Heading A6S [Also in Division G4] The position at which an arrow passes through a flexible target 24 is reproduced a screen 54 close to the archer. The target is painted or projected on a screen 22 made flexible strands. The arrows are stopped by net and returned by a conveyor 40 described in Specification 1295887. A light beam narrower than an arrow is projected by a light on to two continuously rotating mirrors at the top and bottom of a column so that in respect of each target, two beams periodically sweep across retro-reflective tapes (106). As each scan begins a photo 108, Fig. 7, sets bistable 304 to start a count on BC1-BC64. In the absence of an arrow the counter reaches full capacity and then zero so that AN gate 316 resets bistable 304. If the scan detects the passage of an arrow then diffusion of the light beam energises a photo-cell 140 (also Fig. 5) to reset 304 and halt the count at a value representing the angular coordinate of the arrow. At the same time a flip-flop 320 initiates a read period of 5 seconds. A comparator 336 compares the readings of a conductive-segment coded disc 338 (also Fig. 8) with the counter and causes a motor 359 to sweep on arm 357 over the target indicator 54 until equality is attained. Two arms 357 are provided in respect of the two scans. When the movements are completed a lamp 356 lights to indicate where the arrow has hit. An electromagnetic brake 364 is operative whenever the motor is de-energised. A bulls-eye lights a lamp 388 and rings a bell. The number of arrows detected is registered by a counter 366 which can be reset by button 372.

At the elevator, the eggs pass from conveyor 5 and collect against upturned parallel wires of a delivery grating 9 (Fig. 4) which is upwardly pivotally mounted adjacent a downwardly inclined grating 6 at the end of the conveyor 5. The elevator 11 comprises a series of interconnected cups 10 formed by parallel C-shaped wires which are also parallel to the wires of the delivery grating 9 such as to be able to pass between them. A cross brace attached transversely to the cup wires of each cup can engage an indent in an apex of one of two hexagonal driving discs 12 so as to operate the elevator whereby eggs are picked up from the delivery grating 9 by the cups 10. When a cup already containing an egg presents itself to a delivery grating the grating 9 pivots upwardly to prevent pick-up of a second egg. The eggs are ejected onto the conveyor 15 by means of a synchronously rotated shaft 14 whose radially projecting flaps urge the eggs on to the conveyor via an arcuate guide 13.
