Title: Module Insertion Apparatus.
Inventor: ACKERMAN DANIEL WHITNEY
IPC: B23P21/00
Filed: 1967-08-16
Abstract: 1,181,529. Assembling components to circuit boards; straightening. UNIVERSAL INSTRUMENTS CORP. 16 Aug., 1967 [23 Aug., 1966], No. 37734/67. Headings B3A and B3E. [Also in Division B8] Apparatus for inserting electrical component leads into a board comprises component inserter means 200, reciprocating means therefor, support means 300 which supports one component at a time in alignment with the reciprocatory path of the inserter means, and means operable subsequent to positioning a component to effect straightening and aligning of the leads. The electrical components 10 are provided with a number of L-shaped leads 12 and are individually fed from a supply 401 into a shoot 500 by a feed escapement 402 actuated by the apparatus control system. As the component 10 is fed on to the support means, a rib 310 thereon outwardly straightens any bent leads. The component inserter 200 comprises a head member 203 slidably mounted on a tube 202 between upper and lower positions, at which the members are connected for simultaneous movement by a detent 206 engaging in either of recesses 204, 205. A slidable head 224 in the tube 202 is provided with a spring to allow for components 10 of different thicknesses. During downward movement of the members 202, 203 a component 10 is picked up by the tube 202 and when an abutment 210 on the head 203 contacts a screw 114, Fig. 11, the detent 206 is forced out of the recess 204. The tube continues downwardly until the leads of the component 10 are inserted into a circuit board 25 and the detent engages in the recess 205. The leads pass through tapered slots 246 at the bottom of spring plates 236, 237 whereby any outwardly bent leads (12A) are straightened, Fig. 3 (not shown). Surfaces 250 on the tube engage surfaces 242, 243 on the spring plates to force these slightly outwardly to prevent withdrawal of the component 10 when the inserter 200 is raised. The interior of the tube is connected to a vacuum source to hold the component, the source being cut off at the end of the stroke of the inserter. As the inserter is withdrawn, support members 301, 302 are returned to a horizontal position to receive the next component 10 which is placed thereon by an arm 601. On the downward stroke of the inserter, the supports 301, 302 are pivoted downwardly after the component 10 has been seized by the tube 202 by a cam-plate 260 acting on spring-loaded followers 325, 326, Fig. 11. A surface 314 of the support 301 acts as a stop for the next component 10 in the shoot 500 when pivoted downwardly.

Abstract: 967,611. Animal holding means. L. PREMOLI. Oct. 15, 1962 [Oct. 20, 1961], No. 38889/62. Heading A5R. Animal holding means comprises a barrier 15, 16 having openings for the passage of individual animals' heads, a halter comprising a pair of substantially vertical bars 11, 12 in each opening, the bars of each pair being movable to secure or release an animal's head and being free for rotation when closed and fixed in the plane of the barrier when open, and means for simultaneously controlling the bars in a number of openings. The barrier comprises fixed vertical bars 15 supporting upper parallel bars 16. The bars 11, 12 of each halter are hinged together at their lower ends which are slidable supported by a rod 17 on a metal plate 19 within limits determined by short chains 18. The upper ends 11a, 12a of each bar are confined between the upper parallel bars and are embraced by oppositely disposed chain loops 44, 45 each of which is attached to one of a pair of controlling cables 33, 34 which extend the length of the barrier. The cables are connected together at one end by a chain 37 which passes over a sprocket wheel 38 rotatable by a worm gear mechanism 39, 40, 41 to move the cables in opposite directions. The bars of each halter are also connected one to each cable by chains 48, 49. On rotating the sprocket wheel in one direction, the cables are moved to tighten the chains 48, 49 so that each halter is pulled into the plane of the barrier and then opened, the chain loops being simultaneously loosened. When the sprocket wheel is rotated in the opposite direction, the chain loops are tightened to close each halter and the chains 48, 49 are loosened to allow rotation of the halter and so permit the animal some free movement. Frames 14 pivotal on the fixed vertical bars 15 alternate with the halters and are connected at their upper ends by links to a rod 21 slidable into positions in which it pivots the frames to open or close openings between the halters.

Title: Improvements in or relating to pulse code receivers
IPC: B61L25/04
Filed: 1964-09-29
Abstract: 1,043,810. Track apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 29, 1964 [Oct. 2, 1963], No. 39614/64. Heading B7N. [Also in Divisions G4 and H4] In a signalling system in which a series of code groups, each preceded by a synchronizing pulse, is transmitted at a varying speed, the receiver includes means for forming a quantity representing the period between two sync. pulses and for utilizing this quantity to derive scanning pulses during the next period. Two such means are provided, used during alternate periods. The embodiment describes a track-side radio transceiver, Fig. 1, and a transponder, Fig. 2 (not shown), mounted on a wagon. A signal from the main transmitter ZE has sufficient power to operate a motor which provides relative motion between a coded disc and inductive sensing heads and to operate the transmitter section of the transponder which sends back code groups and sync. signals read from the disc. Since the motor does not attain full speed instantaneously it is necessary for the main receiver sampling signals to have a speed dependent upon the speed of the received signals. It is assumed that the change in speed from one code group to the next is not large so that sampling pulses determined for one group can be used for the next. The synchronous pulses are received on aerial PC and the data pulses on PN. Each sync. pulse resets to zero counter TC which is fed by pulses at frequency f 0  from generator GR and also resets one or other of counters TA, TB which are fed by pulses at f 0 /10. If, for example, TA has been counting, when the next sync. pulse starts TB the count on TA will be retained and, comparator CA now being enabled TA and TC are compared. When TC reaches the count on TA a pulse resets TC to zero and switches toggle FB. Thus, between two sync. pulses ten pulses are received from CA, whose timing is dependent upon the count attained during the previous period. The ten pulses are halved by toggle FB and feed shift register SR which samples the received data bits at about their mid-points. When unit CC detects a code group denoting the start of the code group sequence, counter TD is reset to zero. The counter is fed by the sync. pulses, so that each complete code group in SR is transferred to the core memory MG. When the next start group is detected that memory is read out to a utilization unit.

Carriers 6 at spaced intervals on an endless conveyer chain 1 carry spaced fingers 14 (1 only visible in Fig. 5) adapted to be engaged by respective components 19 when one of the latter is selected by a push-button (not shown). The particular one of the group of components 19 (at the loading station) selected by the pushbutton, displaces a corresponding finger 14 depending on the desired unloading station. The displacement of the finger 14 also results in the opening of an hydraulically actuated shutter 10 at the loading station, followed by the turning of a slotted member 16 from the full line to the dotted line position. A ram 17 is then actuated to carry a load 13 from a horizontal, rollerconveyer to a position on the member 16 in which it is picked up by the rising carrier 6. As the chain passes over its upper sprocket the carrier is guided by the interaction of a pivot on the latter and the limbs of a forked member (not shown) carried by a carriage (not shown) which is movable freely on a horizontal slide. The carriage is returned by counterweights. As the carrier 6 descends (Fig. 7) fingers 18 at a selected unloading station are projected by a cylinder 17 activated as a result of the projection of the finger 14. The load is left on the fingers 18 which are then retracted and the load is discharged transversely to the direction of the fingers 18 as described in Specification 954,972. Stops may be provided to prevent articles being presented to an already loaded cradle. A warning may be provided in the case of a loaded carrier for which no discharge station has been selected. The conveyer is applicable to the distribution of passengers' luggage to the decks of a ship.
