Patent GB-530208-A (GB)
Abstract: 530,208. Workmen's time recorders. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1939, No. 19083. Convention date, July 7, 1938. [Class 106 (iv)] A time recorder comprises time registering elements for effecting a registration on a time record, time controlled programme control means comprising a carrier with control areas and programme control elements adapted to be set in said areas and time controlled means. for effecting movement of the carrier in diverse directions to locate each control area successively at a single control position. Impulses from a master clock operate a solenoid 40 whose plunger 41 rocks a lever 42 operating a latch arm 44 connected to a latch 47. The latter operates starting contacts 56 for a motor 60 and also places a pawl into engagement with a ratchet on a shaft 63 driven bv the motor. This ratchet actuates a cam controlling a member 57 which maintains the contacts 56 closed for one revolution of the cam. An arm 70 is also actuated by this mechanism which operates mechanism to restore plunger 41 to its original position and also actuates an arm 76 which through ratchet and pawl mechanism advances the minute type wheel 81. When hour and day type wheels are used these are also advanced positively by mechanism operated by arm 76 no spring carry lever mechanism being used and each wheel being positively power driven. A drum 105 on a shaft 104 is driven by gearing 103 from the type wheel shaft 100. This drum is provided with a number of rows of slots adapted to receive elements 110 which are inserted according to programme requirements. The drum is shifted lengthwise by a cam operated linkage after each revolution in order that each row of elements 110 may be brought successively into operative position. A bail 130 is provided operated by the elements 110 which actuates an arm 131 that swings an arm 133 to cause it to engage with an arm 134. The latter is fixed to a shaft 135 carrying a cam follower 136 operated by a cam on shaft 63 and thus when arm 133 engages with 134 it is depressed periodically by the cam drive. Arm 133 operates a ratchet 140 which through a cam and linkwork shifts the card carriage 150. A bail 155 is also provided which is operated by elements 110 and which actuates ratchet and pawl mechanism for controlling the position of the card abutment. A further bail 170 is provided to ring a bell and a fourth bail 180 actuates mechanism to shift a two-colour ribbon to cause printing in the desired colour to take place. When a time card is inserted in the machine it operates a bell crank lever to put the printing means into operation. The programme control mechanism may be disconnected for out of programme printing. A clock is provided on the face of the machine driven from the type wheel shaft.

[Also in Division C1] In a method of forming passages of predetermined configuration in wafers of thermoplastic material; a soluble core element corresponding in shape to the passages is located in a block of thermoplastic material to form an assembly which is drawn out to a desired length and sliced into wafers from which the core parts are dissolved after each of the wafers have been applied to a base layer. In the first example, Fig. 3, the core 22 is made of a water-soluble glass by extrusion and is located in a mould to define a cavity which is filled with glass rods to form a billet which is located in a furnace, drawn to a diameter of 0À125 inch and sliced. In a second embodiment the core, e.g. of an acrylic, is made by injection moulding using a machined multipart metal mould. A substantially identical metal core is located in a mould to define a cavity into which nylon is forced, the core being removed after cooling. The acrylic core is then inserted into the nylon body to form a block which is heated and drawn and then sliced into wafers.
