Abstract: 1,005,791. Lift control systems. OTIS ELEVATOR CO. Dec. 12, 1962, No. 46945/62. Drawings to Specification. Heading B8L. In a multi-car lift system, means are provided for measuring continuously the differential of travel times of the cars on their upward travels as compared with their downward travels and for automatically selecting an operating programme, such as for "up-peak", " down-peak " or " up-down " operation, in dependence upon the relationship between the measured differential and a predetermined differential. In the described embodiment, a grid condenser of a triode is subjected to a positive charging potential by each descending car and a negative charging potential by each ascending car and discharges to earth when a car or cars is or are standing at the despatching terminal, and the resulting potential of the triode cathode, being a measure of the traffic condition of the system, actuates the appropriate programme selector switches. The charging rate of the condenser is made responsive to the load in each car, irrespective of its direction of travel, by the provision of load responsive switches which, when closed, short-circuit a resistor in the charging circuit of the condenser. The cars are dispatched from the terminal floor at timed intervals which are lengthened or shortened in dependence upon the amount by which the car was early or late as well as upon the magnitude of the dispatching interval then existing, so as to obtain a predetermined spacing between successive cars. Specification 721,988 is referred to.

Filed: 1962-12-14
Abstract: 948,613. Folding fabric. BRITISH LAUNDRY MACHINERY CO. Ltd. Dec. 14, 1962, No. 47278/62. Heading D1S. A machine for folding flat articles about lines inclined to one another comprises a working surface for the reception of the article to be folded, folding arms arranged to pass through the working surface to form the folds and transfer arms for transferring the articles over the working surface from one position to another and for co-operating with the folding arm in at least two positions to fold the articles. The machine may be adapted to make Z-folds or double folds and may also incorporate stacking means for stacking the folded articles. In the arrangement shown an article to be folded is placed in the first folding position 6 on table 3 and is located by stops 9. Control knob 35 is pulled and causes operation of double acting cylinder 20, to rotate cam track 16 and thence shaft 17, through 90 degrees. Rotation of cam track 16, through follower 15, linkage 14, 13, 131 and shafts 12, 12<1>, causes the transfer arms 10, 11 to rotate together through 90 degrees to the positions shown in dotted lines in Fig. 1. At the same time rotation of shaft 17 causes a folding blade carried by radial arms 21 (Fig. 3) to swing up through opening 4 in table 3 and fold the article over the transfer arm 10 in Z-form. The double acting cylinder 20 then returns to its rest position withdrawing the folding blade and rotating the transfer arms 10, 11 to their rest position shown in full lines in Fig. 1. The blade 10 transfers the folded article to position 7. A further article is then placed in position 6 and the control knob operated again. The article in position 7 is then folded again (at right angles to previous folding) by an extension 24 of the folding blade in co-operation with transfer arm 11 and after the folding, the arm 11 transfers the article to position 8, the article at position 6 having been first folded and transferred to position 7. A further article is placed in position 6 and the machine operated again, this time the article in position 8, through link mechanism 29, 30, 27, 28 and plate 31 (Fig. 4) is lifted from the table by plate 31 and pushed past flaps 32 to the bottom of stack 26. The articles in the positions 6, 7 will of course have gone through the folding operations previously described. By adjusting the position of the article relative to the opening 4 the machine can be adapted to make single folds instead of Z-folds.

Abstract: This circuit arrangement satisfies the requirement for a switching system to be designed in such a way that more switching network connections are available than the number corresponding to the product of the number of switching network parts and the number of connections per switching network part. A switching network (e.g. I) with a reversed trunking scheme comprises a plurality of switching network parts (e.g. AI, BI, ... NI) which all have the same number of outputs. All of the switching network outputs which in each case have correspondent switching network parameters are parallel-connected (via V1, V2, V3, Vx) over all the switching network parts (e.g. AI, BI, ... NI). Control sub-units are individually allocated to the switching network parts. A plurality of switching networks (I, II, X) are associated with one switching system (Fig. 2). Their multiple lines (V1, V2, V3, Vx, XV1, XV2, XV3, XVx) are connected to inputs of switching matrices of a further switching stage (KC) in such a way that correspondent multiple lines of the different switching networks (I, II, X) are in each case connected to the inputs of a switching matrix. <IMAGE>
