Abstract: 1439993 Relay test apparatus SIEMENS AG 28 Aug 1973 [29 Aug 1972] 40504/73 Heading G1U In a preliminary step of a method of testing a relay P, Fig. 1, the current through the relay coil as a result of a voltage applied to it by a unit U2 also passes through a selected resistor BV and the voltage e thereacross is compared V (by a connection from e to a not shown) with a reference voltage produced by a device UV1 in accordance with the particular type of relay under test, and any difference between the two voltages is reduced towards zero by a program device PE which appropriately adjusts the effective gain of an amplifier VP and the unit U2. This preliminary step of adjusting the voltage applied to the relay to that value which causes a standard current to flow, is necessary because even though the number of turns of the relay coil will be known its resistance may vary by up to 10% because of irregularities in the winding pattern.

Abstract: 1275154 Automatic analytical apparatus EI DU PONT DE NEMOURS & CO 14 Aug 1969 [16 Aug 1968] 40670/69 Heading B1X In the operation of automatic analytical apparatus sample containers e.g. 116, Fig. 1, followed by at least one deformable test pack 13 (the number depending on the number of tests to be carried out), are transported from a rack 14 to a filling station 16 where they are correctly aligned by a cyclically movable shuttle 18 and where aliquots of sample are transferred from the containers to the associated test packs. When the required number of aliquots has been dispensed the used containers are discarded via shute 22. The test packs 13 are intermittently conveyed, according to pre set machine readable instructions on the packs, through a thermostatted heat chamber where reagents within reagent storage compartments in the packs are transferred to the pack reaction chamber by rupturing the seals between the storage and reaction compartments by means of breakers 30, 31. The reaction mixture is subsequently analysed in the pack by a photometer 32, before disposal via shute 34. The sample containers can carry identification marks. The test pack, Fig. 2B, comprises a deformable transparent pouch 41, peripherally sealed to a headpiece 40 and communicating therewith by an opening 42. Sample is introduced to a chamber 48 via opening 43 or 44 and 42 which can then be covered to seal the system entirely. A chamber 45 which separates the openings 43, 44 can contain a filter, a gel column or an ion exchange resin if pretreatment of the sample is required. Marks 47 are readable by the apparatus to determine the analytical procedure to be adopted. The reagents are stoved in chambers 49-54 which are broken by upward pressure of the sample liquid when the pouch is deformed.

[Also in Divisions G4 and H1] A control system for performing a function when a predetermined number of operations have been effected, e.g. removal of a stack of crates, after a predetermined number of stacking operations, comprises a pivoted guideway 2 having a horizontal extension 2a where counter means, e.g. balls, are stored when the extension is pivoted to the dash-dot position by a ram 3. When the guideway 2 is pivoted to the full line position the leading ball falls on to a pusher 4a which operates every time a crate is stacked so that the balls are pushed stepwise past a spring-biased pawl 5. The leading ball finally contacts an arm 5a of a limit switch 5b which causes a control device (not shown) to remove the stack of crates and to cause the ram 3 to pivot the guideway 2 away from the pawl 5 so that the balls return to the extension 2a. The ram 3 then pivots the guideway 2 again. The limit switch 5b is adjustable on a slide 6 to control the number of predetermined operations required. .

Abstract: 1,109,999. Switches held set and freed mechanically; retractive switches. R. J. W. KENNELL. 29 Sept., 1965 [30 Sept., 1964; 15 March, 1965], No. 41383/65. Heading H1N. A lever-operated switch suitable for telephone switchboards comprises a mounting plate 1 carrying eight change-over contact spring-sets embedded in insulating blocks 17 mounted on both sides of plate 1. Fixed contact springs 4 and 6 are relatively stiff and have apertures in which push-bars 30 and 31 are slidable to actuate movable contact springs, each comprising three flexible blades 10, 11 and 12. Slots 42 in push-bars 30 and 31 are U-shaped (Fig. 12, not shown), T-shaped or stepped, and the blades 11 always urge the push-bars to retract while blades 12 have their ends shaped to be engaged only when the bars are moved by means of lever 28, the blades 10 being disengaged from the slots when they contact blades 5. The lever 28 is pivoted at 21 on a tongue 19 (integral with plate 1) which extends into a slot in the lever and its tip 24 limits the throw of the lever. The lever 28 is centralized by spring blades 27 which act on the push-bars 30 or 31 when the lever is operated and their ends are respectively shaped to provide a locking action in one direction of throw and retraction in the other. A notch in a sliding block 32 urged by spring 35 locates the central position of lever 28 and prevents over-throw on restoration. The lever 28 may be split to provide for independent operation of the contact sets on opposite sides of the plate 1. The switch may be plugged into a multi-terminal socket (49, Figs. 14 and 15, not shown), being located and secured by an offset threaded stud (52) projecting from the switch base for engagement in a captive rotatable threaded member (51) in the socket (49). The switch is mounted on studs on a panel (not shown) by means of threaded rotatable bushes 2.
