Abstract: 1,232,228. Torsional vibration dampers. ARVIN INDUSTRIES Inc. 11 Nov., 1968, No. 53433/68. Heading F2S. [Also in Division G5] A tape recorder, Fig. 1 (in which tape 10 is driven by a synchronous A.C. motor by way of a belt 26, pulley 24 and capstan 20) has the tape speed maintained constant by employing a tuned mass-spring damper acting on the motor shaft. Fig. 2 shows the motor 30 whose shaft 35 carries the damper, the latter consisting of a mass 40 and springs 42. In use, the frequency of the A.C. input at 32 is made half the resonant frequency of the mass-spring system 40, 42. Thus speed variations due to the motor's tending to vibrate at twice the supply frequency are damped out. The frequency of the damper may be adjusted by the screws 45.

Abstract: 1,250,683. Knitting. TEXPATENT G.m.b.H.24 Sept., 1969, No. 46997/69. Headings D1C and D1K. When ladder-proof tubular fabric is knitted in which loops are transferred from one wale to an adjacent wale, the courses from which loops are transferred consist of loops so much larger than those of the other courses that, after transfer, all courses have loops of at least approximately the same size, Fig. 4. This fabric may be combined with fabric in which there is no increase in the size of the loops in the courses from which loops are transferred so that areas of reduced elasticity are produced. Needle cylinder 1 is mounted on a bush 4 rigidly secured to the machine frame 5 and its upper edge is surrounded by a sinker ring 8 rotatable therewith and having sinkers 10 which in addition to their role in knitting act as the sinkers of a welt dial during the formation of a turned welt. Mounted above cylinder 1 is a stationary cover plate carrying a thread-gripping device 13 and mounted on a pedestal 14 on frame 5 are two thread guides 15. Mounted eccentrically above cylinder 1 is a body 17 driven by the main drive so that transfer sinkers 19 which are carried in longitudinal tracks 18 move at a slightly different speed from needles 3. Sinkers 19 operate in certain courses to transfer loops laterally. The needles 3 are controlled by fixed and adjustable stitch cams 23, 24 respectively.

Abstract: 1,252,417. Programmed electric control. E.M.I. Ltd. Feb.24, 1969 [Nov.23, 1967], No.53452/67. Heading G3N. In an automatic machine having work and tool supports capable of relative displacement in at least one co-ordinate direction, a record track and a sensor are arranged to undergo relative displacement corresponding to that of the supports, the sensor and track co-operating with a selectable programme arrangement for causing an actuating means for exercising control functions on the machine to respond to signals from the sensor in a different order from that in which they are recorded. A milling machine having a relatively fixed tool head (5) and movable slide (2) has a magnetic tape or band (6) fixed to the bed co-operating with record/reading heads (7) attached to the slide 2. A programme is developed by performing operations manually and recording them. To reproduce operations on a workpiece (4) the heads are switched to a "read" mode. By means of a multi-level uni-selector US1-4, which is switched one step on completion of each operation, and gates a1-a6, b1-b6, slots (27-30) on workpiece (4) may be machined in the same order. The uni-selector contacts are selectively connectible to the gates by plugs and sockets PB1-4 hence slots may be machined in an order different from that in which they occur spatially. The slots need not be a co-linear as shown but may be displaced vertically and overlap horizontally. This is achieved by a separate track on the tape and corresponding head which is switched appropriately when the slide is moved forwardly. Inter-locks may be provided to ensure selection of the correct sensor. Alternatively a separate tape may be provided. If desired, each operation may commence from a datum position also the slots may be cut from either direction. A tape may additionally be provided in a co-ordinate direction so that inclined slots may be cut. For differring depths of cut, affixed to the tool support may be another tape co-operating with a sensor coupled to the tool and connected to a further level on the uni-selector.

Abstract: 1,264,824. Transistor bi-stable circuits. GENERAL INSTRUMENT MICRO-ELECTRONICS Ltd. 17 June, 1969, No. 30707/69. Heading H3T. [Also in Divisions G4-G6] Accelerated carry up or down is effected by storing a pre-carry condition in the capacitance of an FET between count signals so that the succeeding count signal renders another FET conductive to produce carry virtually simultaneous with the count signal. NOR gate G1 or G2 controlled by inverse signals from a decimal counter which may be B.C.D. produce an output 1 so that G3 produces 0 and AND gate G4 produces 0 when (a) the counter is at 9 and going up or at 0 and going down; and (b) in the interval between count signals. In these conditions a pre-carry signal is stored in the capacitance of an FET (Q3, Fig. 2) in G4. When the invert of the count signal changes from 1 to 0 an FET (Q1, Fig. 2) in NOR gate G5 conducts so that a push-pull gate G7 produces a carry output. Feedback from inverter G6 combined with count signal in AND gate G8 provides stability.  Circuit details.-The FET system of Fig. 2 acts as a bi-stable circuit with the arrangement to the right of point B held quiescent by feedback from point 16 through Q7 to 18 as long as no pre-carry signal appears at point A. When this happens the potential on the gate of Q3 from count stores a charge on its capacitance and the succeeding loss of potential from count on the gate of Q2 upsets the bi-stable so that Q1, Q2, Q8 conduct to act in push-pull on Q5, Q6 to produce an output.

As shown, the supplementary spring 19 is mounted between a fixed base 17 and an arm 18 which carries the snail cam 14 and is pivotably mounted on the base 17, the arm 18 having a projection 20 engaging a clearance hole 21 which defines the deflectable limits, a rubber sleeve (22) being arranged on the projection 20 (Fig. 4, not shown) to prevent chatter noise. In Fig. 2 (not shown) a torsionally loaded hollow end-face cam (114) replaces the snail cam and operates on a similar principle in which sudden shock loads are absorbed by axial movement of the cam assembly on a spring-loaded sleeve (118) limited in axial movement. In Fig. 3 (not shown) the snail cam (214) is directly mounted on the fixed base (217) and acts through a limited deflection leaf-spring (219). Figs. 4 and 5 (not shown) are similar to Figs. 1 and 3, respectively, with the additional feature that the snail cam surface and/or the tensioner blade are serrated to increase the frictional self-locking action, and the cam may be of oscillating-suppressing rubber.
