Title: A Model Vehicle Track System
IPC: A63H30/02
Filed: 1968-03-18
Abstract: Model vehicle track systems comprise tracks having a series of spaced substantially parallel conducting strips, alternate strips being electrically connected together and vehicles having at least three electrical collectors which are such. that when a vehicle is facing along the track or at a small angle to it at least one collector engages a strip of one set whilst at least one other collector engages a strip of the other set: across alternate strips there is applied a manually controlled composite voltage incorporating a driving component and a superimposed pulsed steering component and the vehicles have control circuits to separate out the two components which are then used for their respective purposes. The driving component may be A.C., D.C. or pulsed D.C. If the track has two or more vehicles the steering components for different vehicles will have different frequencies. The vehicle may be steered by moving the front wheels by disc brakes contacting the left and right hand wheels or by a shaft from the front wheels driven by the main motor which has a wheel on the end which pivots and may contact either rear wheel to cause a braking effect.. The vehicle may be driven and steered by having two motors, one on each rear wheel, the relative speeds of which are controlled by the steering component of the composite voltage. The adhesion of the vehicle is improved if the strips are ferromagnetic and the collectors are magnetic. The track may have side barriers which may be resilient or electrically energised.

Title: Apparatus for conveying and filling capsules
IPC: A61J3/07
Filed: 1969-11-14
Abstract: Capsule handling apparatus for successively conveying a capsule having body and cap portions 22B, 22A through capsule-feed, -separating, -filling, -assembling, and -ejection stations, comprises an endless chain conveyer 20 guided on sprockets 26-31 and provided with a plurality of pairs of complementary capsule holders 32, 39 for carrying the capsule body and cap portions respectively, and a cam track 43 for moving the cap holders 39 into and out of alignment with the body holders 32 in a predetermined sequence as the holders are carried through the various stations. The body portion holders 32 are formed by the connecting pins of the conveyer chain links and are provided with body support shoulders. Each cap holder 39 is formed by a bush carried on the free end of an offset arm 38 whose other end is pivoted on a chain link connecting pin so that the cap holder may be pivoted into and out of alignment with the body holder constituted by the adjacent connecting pin. Alignment or misalignment of the pairs of capsule holders is effected by engagement of the cap portion holders in a groove 43B in a cam track 43. In operation, empty assembled capsules 22 are fed down a tube 45 from a turret feed station (not shown) at sprocket 26 into each aligned pair of holders. The aligned holders and the empty capsules are carried by the chain to a separating station 46 where vacuum is applied to the base of the body portion holders, Fig. 6 (not shown), to separate the body portions from the cap portions. The complementary cap and body portion holders are then moved out of alignment as they are conveyed to a filling station (not shown) at sprocket 27. At the filling station the body portions are filled with a predetermined amount of a powder by a pick-up 49 associated with rotating turret (not shown) synchronized to the sprocket 27. The cap holders are then brought back into alignment with the body portion holders as they move from the feed station over a tensioning sprocket 28. As the aligned holders are carried around the sprocket 29, they are carried through assembling and ejecting stations, Figs. 8-10 (not shown), wherein camactuated reciprocating fingers, which are carried to synchronized turrets above and below the chain run, firstly raise the filled body portions of the capsules into engagement with the cap portions, and secondly lift the thus assembled capsules out of each pair of holders, an air blast 52 dislodging the capsules from the fingers, Fig. 10, into a collector (not shown). The emptied holders are then misaligned and carried through a purging station at sprocket 31 where reciprocating fingers 54, Fig. 11 (not shown), remove any remaining jammed capsule portions from the misaligned holders. The cycle then recommences.

Title: Method for producing semiconductor rectifier arrangements
IPC: H01L29/861
Filed: 1970-12-19
Abstract: An improved method of simultaneously making a plurality of semiconductor rectifier circuit arrangements of the type wherein semiconductor rectifier wafers are selectively inserted at the points of overlap of two planar conductors which then contact the opposite surfaces of the wafers. According to the method of the invention a pair of planar partial conductor bands are formed from a strip of planar conductive material so that each band contains a periodically repeating pattern of conductors which are formed so that associated patterns on the two bands will form the desired circuit arrangement when placed on top of one another. Each of the bands is formed so that its conductors extend from a common edge zone which may be utilized as a transport strip with the conductors of a first of the bands being provided with planar sections which can hold and support a semiconductor wafer. The wafers are then placed at the desired locations on the provided sections of the first partial conductor band, the other partial conductor band is then placed thereover with the proper orientation so that each wafer is between an overlapping pair of conductors and contacted on both of its surfaces, and then the two partial conductor bands are mechanically fastened together by means of their edge zones. The resulting structure is then subjected to the further processing steps of permanently bonding the wafers to the contacting conductors, cutting or separating the conductor pattern, if required, into the desired circuit arrangements and encapsulating of the individual rectifier devices. Finally, the conductors are severed from the common edge zone.
