Abstract: 1350357 Conveying and transferring cigarettes AMF Inc 8 Sept 1972 [11 Sept 1971] 41856/72 Heading B8A Cigarettes S have their orientations changed as they are conveyed on an elliptical orbit by being picked up by suction carriers 309. Each of the latter is pivoted at spaced points to a point 22 on the circumference of a rotating bellshaped member 1, and a point 23 on a head 6. The latter is mounted eccentrically on the member 1, and is geared by gears 11 and 13 to rotate at the same speed as the member 1. The latter is rotated by a belt 15 and gear 14. The carriers 309 are connected by conduits 16 with a suction chamber 19. The latter is arcuately shaped so as to connect each conduit 16, and cut it off, at points corresponding to desired positions of cigarette pick-up and discharge. In Fig. 2, cigarettes S1 are transferred directly from flutes in a wheel T1 to a belt N. Cigarettes S2 are initially axially disposed relative to cigarettes S1 in the flutes of the wheel T1 with their filter tips adjacent the tips of the cigarettes S1. They are picked up and turned round end-for-end by a device according to the present invention and are dropped into the flutes of a wheel T3. They are then transferred to the vacant alternate spaces on the belt N by a further wheel T4. In a further application (Fig. 3, not shown), cigarettes are transferred between two conveyer belts disposed at right angles.

Patent GB-1237481-A (GB)
Title: Improvements in or relating to processes for the reduction of electric contact resistance
IPC: H01L49/02
Filed: 1969-08-26
Abstract: 1,237,481. Printed circuits. SIEMENS A.G. 26 Aug., 1969 [27 Aug., 1968], No. 42338/69. Heading H1R. [Also in Divisions C7 and H2] In an integrated circuit &c. having conductive strips formed by vaporization, cathode sputtering, chemical deposition, or electroplating, the contact resistance between superposed conductive strips is reduced by applying electrical energy from a charged capacitor to the junction. The invention is particularly applicable to A1 conductive strips, and the contact resistance may be caused by oxidation, varnish or other foreign matter or absorbed gases, or may result from incidental chemical processes. Preferably the P.D. between the plates of the charged capacitor is between IV. and 20V. Embodiments described include bridging strips deposited over insulation to connect conductive strips on either side thereof, and link conductors which effect connections at cross-over points on a cross-bar matrix.

Title: Shift register
IPC: H01L21/339
Filed: 1972-09-13
Abstract: 1400784 Shift registers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 Sept 1972 [16 Sept 1971] 42506/72 Heading G4C [Also in Division H3] A shift register comprises input and output registers, various stages of the input register being connected to corresponding stages of the output register via further registers. Each stage of the register includes a capacitor, and signals are stepped through the registers by clock pulses, the shift rate of the input and output registers exceeding that of the further registers. As shown in Fig. 1 the stages each comprise an FET and capacitor, though each may be formed of two FETs and a capacitor, Fig. 3 (not shown). A signal from Vo supplies input register I. Clock pulses V B , V Y , Fig. 2 (not shown), step successive samples of the signal through register I until they lie in stages 0, 2, and 4. These stages are connected to the further registers a, b, c. When a clock pulse V X  occurs the signals in stages 0, 2, 4 of register I are transferred simultaneously to the first stages of a, b, c and are stepped through these registers by clock pulses V C , V D  which have 1/3 the repetition rate of V B . The final stages of a, b, c are read out simultaneously to output register II by a clock pulse V X , and the signals are stepped through register II by clock pulse V A , V B , to appear sequentially at output 0. Since transfer of signals in to and out of the registers a, b, c is controlled by the same clock pulse V X  the reference level is the same for all the signals and depends on V X  alone. Consequently, should the amplitudes of V A , V B  or V Y  differ from that of V X  no additional distortion will be introduced.

Title: Improvements in or relating to polyesters and polyurethanes
Inventor: RIO ANDRE LOUIS ARMAND
IPC: C08G63/685
Filed: 1964-10-19
Abstract: A polyurethane or polyester is prepared by reacting either an organic diisocyanate or terephthaloyl chloride respectively with a suspension of a finely-divided diol in an inert liquid organic diluent in which both diol and polyurethane or polyester (as the case may be) are insoluble but the organic diisocyanate or terephthaloyl chloride (as the case may be) is soluble.  The diluent may be diphenyl oxide, decahydronaphthalene or di-(a -methyl benzyl)-oxide. The diol may be an oxamide diol of formula HO(CH2)nNHCOXCONH(CH2)nOH, where n is 2-6, X is a single bond or <FORM:1067546/C3/1> or a group of formula -CONHY-NHCO-, where Y is -(CH2)m-, where m is 2 to 6 or <FORM:1067546/C3/2> where Z is -CH2-, -SO2- or -PO(CH3)-. When the diol is solid at the reaction temperature it is employed in finely divided form and is kept in suspension in the inert diluent.  When the diol or final polycondensate is a liquid at the reaction temperature it may be kept in finely-divided form by vigorous stirring.  The polycondensation may be carried out under pressure. In Examples (1), (3), (4), (5), (6), (7), (8), (9), (10) and (11) N,N1-bis-(b -hydroxyethyl) oxamide, 1,6 - bis - (b  - hydroxyethyloxamido) hexane, N,N1 - bis - (g  - hydroxypropyl) oxamide, bis - p,p1 - (hydroxyethyloxamido) diphenylmethane, bis - N,N1 - (b  - hydroxyethyloxamido) piperazine, methyl bis-(m-b -hydroxyethyloxamido) phosphine oxide and bis-p,p1-(b -hydroxyethyloxamido) diphenylsulphone were reacted with either 1: 6-diisocyanatohexane or diphenylmethane 4,41-diisocyanate or in Example (2) with terephthaloyl chloride.

Filed: 1973-10-01
Abstract: 1452514 Data store SIEMENS AG 1 Oct 1973 [29 Sept 1972] 42603/73 Heading G4C A data store includes a plurality of MOS storage cells, means to effect regeneration of stored data in one part of the store 1, 2, in response to a storage access in the other part, register means Gm being provided to contain regeneration addresses identifying corresponding groups of storage cells and to select a group in each part of the store in which regeneration is to be performed within a given regeneration cycle, and further means R1, R2 to respond, after the expiration of a regeneration cycle, to cause any cells within the currently selected groups which have not been regenerated to be regenerated. The cells which are such as to require regeneration within a time T from the previous regeneration are divided into m groups (rows) in each of, as shown, two parts 1, 2. Any read write access to a location in either part causes the cell identified by group counter Gm and counters R1 or R2 in the other part to be regenerated. Each regeneration steps the appropriate counter R1 or R2 to the next cell. The group counter is stepped to point to the  next group after a period T/m, any cells in the selected groups which have not been regenerated, identified by counters Rl, R2, being regenerated before the group counter is stepped. In this way all cells are regenerated within the required period and the number of occasions on which access requests are blocked due to regeneration being performed other than as a result of such an access, is reduced.

Title: Hoist
IPC: A61G7/10
Filed: 1972-09-16
Abstract: 1440919 Hoists DELTA DESIGNS (NEW SOUTHGATE) Ltd 13 Sept 1973 [16 Sept 1972] 43028/72 Heading B8B A hoist for supporting a harness on a cable 2 coiled on a shaft 34 driven from an electric motor 32, and all mounted in a casing, includes a motor reversing switch manually operated by pull cords 82, 84, a motor current interrupting switch operated upon overwinding of the cable, and motor current interrupting switch 50 operated upon a predetermined amount of cable being payed out. The unwind limit switch 50 is operated by an arm 52 engageable by an adjustable stud 54 on a housing 56 which screw threadedly engages a threaded shaft 58 driven in correspondence with the cable shaft 34. Due to interengagement between a fixed shaft 60 and pins 62 on the housing 56, the latter cannot rotate with the shaft 58 but moves axially therealong representing cable movement, to engage the arm 52 just prior to complete cable pay out. The overwind switch is operated by a pivotal lever 92 engageable by a member 94 on the cable 2 when the latter reaches its upper limit. The member 94 is mounted through a spring 96 on a member 98 secured to the cable 2, facilitating slight overrun of the loaded cable after the motor switch has been operated. Actuation of the overwind switch causes the motor to stop and then reverse to unwind cable until the lever 92 is disengaged from the member 94 whereupon the motor will again reverse to wind up cable unless the normal pull cord "lift" switch has been switched off. Manual operation of the hoist is facilitated by a hexagonal projection on the shaft 34 extending beyond the casing. In the embodiment of Fig. 7 (not shown) the harness is connected directly to the inverted hoist casing and the cable extends from the casing for coupling to an overhead support.
