Abstract: 958,815. Pipe joints. CONEX-TERNA Ltd., and F. WHITWORTH. Dec. 7, 1962 [Dec. 7, 1961], No. 43797/61. Heading F2G. A resilient sleeve 14 is inserted within a member 10 having an inturned lip 15 which frictionally engages the outer surface of the sleeve and co-operates with an out-turned lip 17 on the sleeve to determine the fully inserted position of the sleeve. The joint is completed by inserting the member 11 into the sleeve and member 10, the sleeve then being in sealing contact with the two members and there being a space 18 between the sleeve and member 10. The application of a force which tends to withdraw the member 11 from the member 10 results in the deformation of the sleeve to fill the space and engage the member 10 to thus provide a frictional force opposing withdrawal of the member 11. The lip on the member 10 may be formed by a flange or by an inward taper of that member. The sleeve may have an internal bulge.

Abstract: 1279200 Endless conveyers; shoots STORK AMSTERDAM NV 23 Sept 1970 [25 Sept 1969] 45286/70 Headings B8A and B8S A device for transforming the direction of movement in respect of the principle axis of symmetry of each of a series of cylindrical containers 1 comprises a horizontal endless conveyer 2, which advances the containers between a pair of guide rails 6, 13, the rail 6 extending over a transversely inclined endless conveyer 3 with a longitudinal ridge 5 in alignment with the belt 2 and a braking roller 8.

The containers, under the influence of gravity, then roll over the ridge and across the conveyer 3 and subsequently engage the roller 8 which stops their movement in the original longitudinal direction. The roller is driven such that its peripheral speed corresponds to that of the containers as they pass thereunder for delivery to a shoot 10 with a twist section 11 to rotate the cans through 90 degrees prior to delivery to a conveyer 12.

Title: Receiving circuits for compatible broadcast stereophony
IPC: H03D1/22
Filed: 1962-11-30
Abstract: 1,020,951. Stereophonic systems. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Nov. 30, 1962 [Dec. 2, 1961; Sept. 24, 1962], No. 45340/62. Heading H4L. In a compatible stereophonic system, wherein the first detector output of the receiver is a composite signal comprising the audio sum signal (R + L), a pilot frequency and an I.F. carrier amplitude modulated with the difference signal (R - L) (with suppressed carrier), a switching oscillation of the same frequency as the I.F. carrier is derived from the pilot frequency and applied, together with the composite signal, to a ring modulator in such a way as to produce the sum and difference signals in phase at one output and in antiphase at another output of the modulator. As shown, the composite signal from the first detector (not shown) is fed through a valve 1, a capacitor 25 and coil e to the diagonal points a, b, of a ring modulator consisting of diodes 8-11, resistors 12-15, and potentiometer c, d (for balancing the modulator). The pilot frequency (19 kc/s.) is filtered from the composite signal by a tuned circuit 3, frequency doubled at 4, 5 to that of the I.F. carrier (38 kc/s.), amplified at 6 and fed by way of a circuit 7 tuned to 38 kc/s. to the coil e. This switching signal thus appears across the points a, b of the ring modulator with a phase-shift of 90 degrees due to the transformer coupling 7, whereby the sum and difference signals are derived in phase at c and in anti-phase at d so that the R and L signals appear, respectively, at output terminals A, B. To correct the amplitude relationship of the sum and difference signals at the points c, d, a preset portion of the sum signal (R + L) derived from a potentiometer 16 in the anode circuit of valve 1 is fed to the point f rather than directly to points c, d, to avoid upsetting the balance of the ring modulator. Resistors 17, 19, 21, 22 and capacitors 18, 20 act as a de-emphasis network and suppress unwanted high frequencies applied to point f. To improve signal/noise ratio, a biasing voltage is, in a modification, Fig. 2 (not shown), applied during monophonic reception to the diodes of the ring modulator to shift their working points to linear points of their characteristics. This biasing voltage may be derived from the cathode of valve 1 by connecting a diode across capacitor 25. For stereophonic reception this biasing voltage is balanced out by a compensating voltage derived from the frequency doubled pilot signal by rectifying a portion thereof derived by inductive tapping from the anode circuit of valve 6.

Abstract: 1,122,724. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORP. 11 Oct., 1966 [28 Oct., 1965], No. 45362/66. Heading H4T. In a cathode-ray tube display arrangement in which beam deflections are produced by applying, via switch means, step currents to the deflection circuits, undesired variations of the current in these circuits during the switching operation are prevented from occurring by the provision of shunt means rendered operative during the switching operation to shunt the applied current step from the deflection circuits. The invention is described in connection with an arrangement in which transistor switches S 1 , S 1  . . . SN, SN controlled by the bipolar outputs of X and Y binary registers 11, 11<SP>1</SP> respectively supply binary weighted current sources I 1 , I 2  ... IN, with opposite polarities to the push-pull deflection windings X, #X and Y, #Y. Because of the different current levels the different switches require different switching times and the current flow in the windings therefore varies undesirably during such, transient, switching moments resulting in a beam movement referred to as " beam skew." To eliminate this the invention provides shunt circuits comprising diodes D 1 , D 2  and D 3 , D 4  for the X and X deflection windings (with similar elements for the Y and Y windings) which are rendered operative by transistor switches 16, 18 for periods embracing the operation of the switches S the action being to limit the voltage swings of the points P 1  and P 2  below and above, respectively, a nominal value which is approximately midway between the voltages V 1 , V 2  applied to the switches 16, 18 under steady state conditions.
