Title: Improvements in Ball and Socket Joints
IPC: F16C11/06
Filed: 1966-10-31
Abstract: 1,157,707. Ball joints. V. LANGEN [trad ing as A. EHRENREICH & CIE]. 31 Oct., 1966 [30 Oct., 1965], No. 48768/66. Heading E2F. Ball and socket joints Wherein at least two bearing surfaces bear against each other and at least one of these bearing surfaces is formed of "artificial coal", i.e. a material made by burning, baking or sintering a mixture of carbon powder (e.g. natutally occuring carbon such as graphite or ordinary coal ground to powder or by-product carbon such as coke soot or retort cartoon) and a binding agent (e.g. tar) and, if desired, subsequently graphitizing, e.g. electrode graphite. The other surface against which the "artificial coal" surface bears may be formed of metal, e.g. steel, or this surface may also be of "artificial coal",- the two "artificial coal" surfaces preferably having different sliding properties. As shown in Fig. 4, one joint according to the invention comprises a composite ball head comprising the head 9 on the joint pin 2 which is in bearing contact with the cover 11 (both being made of metal) and an annular bearing element 10 of "artificial coal" in bearing relation with an annular bearing bush 13 also of "artificial coal". The members of "artificial coal" may be formed by cutting, moulding or otherwise shaping the material, which may contain friction-reducing or -increasing additives. After forming the metal bearing surface to shape, no further refinement e.g. hardening or chromium plating, is required.

Filed: 1975-10-23
Abstract: 1501638 Television PLESSEY CO Ltd 23 Oct 1975 [13 Nov 1974] 49084/74 Heading H4F Image sensing and storing equipment comprises a matrix M of photo-electric sensing devices on to which light from an image is focused by a lens L on opening a shutter E, each device being capable of developing an electric charge whose magnitude is a measure of a quantity of light received by the device, means operable to read the magnitude of charge in each device, an analogue-to-digital converter C delivering, in respect of each device of the array, a digital signal indicating the magnitude of the respective charge, a digital store B for said digital signals, and means operable to read out the stored digital signals at a rate compatible with transmission of the signals within the speech signal bandwidth of a speech transmission channel. To operate the equipment, a button p1 is depressed to open the shutter and allow light to fall on matrix M. On pressing button p1, a delay device Y is actuated to time a delay and, on expiry of the delay, to supply scanning pulses from a frequency generator F to matrix M, whereby read-out of the matrix is effected. The store B stores the digital signals until a time when the operator desires to transmit the image to a receiver, a portable radio set W having an antenna A being connectible at D to the equipment for this purpose. To transmit the image, the operator depresses a button p2, a frequency divider V1 then delivering drive pulses at a frequency within the said bandwidth to operate a serial switch S. Switch S delivers at said frequency a series of digital pulses representing a signal read from store B, which store comprises five registers r1-r5. The signal passed to switch S thus comprises a parallel signal of five binary digits, enabling 32 shades of grey to be transmitted. The button p2 may be manually or remotely controlled. A plurality of such equipments may be associated with one radio set, the disconnectible connector taking the form of a selector which connects the equipments one at a time to the set W.

Title: Sealing device for packing machines
Inventor: WAHLE GUENTER
IPC: B65B51/10
Filed: 1965-11-22
Abstract: 1,114,495. Package sealing apparatus. HAUM-WERKE KORBER & CO. KOMM. GES. 5 Sept., 1966 [22 Nov., 1965], No. 49486/65. Heading B8C. [Also in Division B5] A hollow heating member 6 for sealing transparent film wrappers is maintained at a constant temperature by the circulation therethrough of a heating liquid which has a substantially greater overall heat capacity than that of the heating surfaces of the member 6 and means are provided for heating the liquid to an accurately regulated temperature at a point externally of the member 6. As shown in Fig. 1, the heating liquid is fed by a pump 10 through a temperature sensing device 14 into a supply container 2. A heating element 18 for the liquid is provided in the container 2 and has one lead 20 directly connected to current supply terminals 26 whilst the other lead 22 is connected thereto through a contact of a relay 24. One lead 28 of the device 14 is directly connected to current supply terminals 31 and the other lead 30 is connected thereto through the winding of the relay 24. Initially, the device 14 energizes the winding of the relay 24 to close the relay contact. When the element 18 has heated the liquid to the required temperature, the device 14 interrupts the flow of current through the relay 24 and thereafter the relay contact opens or closes successively when the temperature rises above or falls below the required value. The flow rate of the pump 10 is so controlled that the amount of heat in the liquid which flows past the heating surfaces of the member 6 always represents a multiple of the heat withdrawn from these surfaces by the sealing operation. In one application of the invention to a packaging machine, Fig. 2, packages 282 wrapped in transparent film wrappers 284 are inserted step-by-step into a ductway 234 forming the first step of a step-shaped track 232. A tubular seam of each package 282 is welded by a heating strip 266. The packages 282 are then conveyed over the upper step of the track 232 to a second ductway 236 and in the course of this movement and on insertion into the latter the end flaps and tucks are folded. Heating strips 268, 270 effect sealing. The heating strips 266, 268, 270 form wall parts of the ductways 234, 236, are part of heating members 206, 242, 244, respectively, and are movable towards and away from the packages. The members 206, 242, 244 are heated by the circulation of heated liquid from a container 202 through the pipeways shown, the temperature of the liquid being controlled as described with reference to Fig. 1.

Abstract: 1,134,107. Switching circuits. SOLARTRON ELECTRONIC GROUP Ltd. 2 Dec., 1965 [4 Dec., 1964], No. 49513/64. Heading H3P A switching circuit of the type comprising a rectifier bridge in series with input and output terminals has a floating bias supply across the opposite terminals of the bridge. Thus in Fig. 3, the bridge 15 is biased by a battery 28 and resistor 29, but it can be supplied from the rectified mains with suitable capacitive and resistive isolation. When terminal 22 is positive with respect to 23 the rectifiers 20 and 21 are cut off, the bridge rectifiers are forward biased by the battery 28 and a signal can pass from 12 to 13. When terminal 22 is negative with respect to 23 the rectifiers 20 and 21 conduct and the negative voltage from 22 over-rides the battery voltage to back-bias the bridge rectifiers. At the same time a further rectifier bridge 30 is rendered conductive to earth the input to the bridge 15. The load 11 may be a summing amplifier in an analogue computer. The bridge 30 may be omitted (Fig. 2, not shown).
