Abstract: 1,270,481. Automatic exchanger systems. SIEMENS A.G. 8 July, 1970 [9 July, 1969], No. 33091/70. Heading H4K. An exchange employing a sampling (e.g. scanning) control device controlled by a stored program central control and arranged to receive from the control the address of a peripheral device to be sampled, to repeatedly increment this address thus generating the addresses of a set of peripheral devices and to enter this information in a set of storage locations selected by the central control and arranged to store also the peripheral devices addresses. As described the peripheral devices include trunk and junctor supervisory sets, digit receivers, identifiers, cross-point control devices and error monitoring devices. The peripheral devices are arranged in sets of devices of the same type and devices within a set have consecutive addresses so that the control device can be given a starting addresses increment it by one repeatedly to generates all the addresses of the set. The central control allots a group of storage locations which may or may not be consecutive to receive information relating to the states of the set of devices to be scanned and these locations also receive the addresses of these devices. The number of locations allotted to a set of devices may be less than the number of devices if it is unlikely that all devices will have changed state. The common control processor extracts the data from storage when processing time is available. If the storage space becomes full the transfer of further information to storage is inhibited. The switching network may be of contact making type or a T.D.M. system using intermediate storage.

Title: Improvements in or relating to the production of elastomers of polyvinyl chloride
IPC: C08K5/01
Filed: 1947-12-18
Abstract: An elastomer is made by heating together, e.g. at 150-175 DEG  C., polyvinyl chloride, a true plasticizer therefor, e.g. dibutyl or dioctyl phthalate and tricresyl phosphate, and a high boiling aromatic hydrocarbon extract, both together amounting to 250 to 800 per cent of the polyvinyl chloride.  The extract is obtained in the refining of petroleum by treatment with polar solvents such as liquid sulphur dioxide and furfural (Edeleanu process) or with sulphuric acid or by the vacuum distillation of petroleum residues followed by treatment with sulphur dioxide.  The hydrocarbons have molecular weights between 200 and 800.  Pigments, e.g. titanium dioxide, stabilizers, e.g. lead stearate, carbonate or silicate, and detackifiers, e.g. ethyl palmitate, castor oil and paraffin wax, may be added.  The polyvinyl chloride may be precompounded with the true plasticizer and then compounded with additional polyvinyl chloride, if required, prior to compounding with the hydrocarbon extract.  The composition may be used for making casting moulds.

Title: Improvements in or relating to phonographs
IPC: G11B3/08
Filed: 1954-11-22
Abstract: 787,392. Phonographs. INDUSTRIAKTIEBOLAGET LUXOR. Nov. 22, 1954 [Dec. 2, 1953], No. 33723/54. Class 40 (2). A record groove sensing device for use with phonograph pick-ups intended for playing round disc records having different types of sound grooves comprises a sensing member which is laterally movable both with and relatively to the pick-up, is arranged to track the groove to distinguish one type from another, and operates either to close, or not to close, a pair of electrical contacts which control a relay which renders effective the required needle and/or turntable speed. As shown, the member consists of a needle 9 in the front part of an arm 8 pivoted about a pin 7 extending from a plate 3 in turn pivoted by a pin 4 in a support arm 1; the arm 8 is biased by a torsion spring 13 to a position in which a contact 10 at its rear part is spaced from a contact 11 on a spring supported by an insulated part of the arm 1. The device is presumed to be used with a record changer in which records are dropped one at a time on to a turntable and there stacked, and the arm 1, as described in Specification 749,128, which is referred to, supports the pick-up arm (not shown) when the two are set down by the changer mechanism near the centre of the record; by its roller 2 the arm 1 carries the pick-up arm radially outwardly of the record in response to record rotation until the roller drops off the edge of the record, whereupon the pick-up needle is deposited in the starting part of the groove. During this outward movement the needle 9 engages the groove which if it is that of a 78 r.p.m record, prevents the needle 9 from accompanying the arm 1 and, by pivoting arm 8 about pin 7, closes contacts 10, 11 to select the appropriate pick-up needle and turntable speed; if the record has micro-grooves the needle 9 does not engage them sufficiently to rock arm 8, whereby the needle and speed appropriate to 33<SP>1</SP>/ 3  r.p.m. is selected. The engagement of needle 9 with the record groove is made during only a limited period of the outward movement of the arm 1 by a member (not shown), which controls the height of plate 3 in dependence on the angular position of arm 1 in relation to the centre of the record. In another embodiment (not shown), needle 9 is replaced by an acute edged groove engaging where rotatable on the same shaft as roller 2, and the steeper groove spiral of a 78 r.p.m. record effects during the sensing period sufficient axial movement of the wheel to engage directly a pair of contacts which effect the selection.
