Title: Improvements in or relating to record changing gramophones
IPC: G11B3/12
Filed: 1946-05-03
Abstract: 611,658. Magazine gramophones. INDUSTRIAKTIEBOLAGET LUXOR, and WENNERBO, E. May 3, 1946, No. 13466. [Class 40 (ii)] In a magazine gramophone in which records are lowered one by one on the top of each other on the turntable, or are removed from the turntable one by one, the stylus of the pick-up is automatically maintained at a constant angular relation to the uppermost record by making the tone-arm support movable in a vertical direction and associating it with a ratchet which permits free upward movement during a record-changing operation, but locks the support against further downward movement as soon as the stylus comes into contact with the uppermost record. In the embodiment described with reference to Fig. 1, the tone-arm is supported by a toothed rod 10, which is rotatable with a bearing 9 within which it is free to move in a vertical direction under the control of mechanism, not shown, during a record-changing operation. As the rod 10 is raised, the stylus 5 remains in contact with the uppermost record until the depending rod 20 comes into contact with a pin 25, and until the lower end of rod 20 has moved the plate 15 to the right so that the surface 16 rests against the rod 10. During further upward movement of the rod 10, the tone-arm is lifted bodily so that the stylus 5 leaves the record. After the placing or removal of a record, the rod 10 is lowered, during which operation the stylus 5 again comes into contact with the surface of the record, the tone arm is moved clockwise about the supporting pin 11, and the plate 15 under control of the depending rod 20 is moved so that the sharp edge 17 of the plate 15 is moved to engage one of the teeth on the rod 10, which is thereby prevented from being lowered further. Figs. 3 to 8 inclusive (not shown) illustrate another embodiment in which both the support rod and control member pass through the support bearing, and a spring is provided between the tone-arm and the support member to relieve stylus pressure,

Title: Improvements in or relating to cutting arrangements for cutting longitudinally moving webs
IPC: B26D1/38
Filed: 1965-03-31
Abstract: 1,069,123. Cutting webs. A. SCHMERMUND. March 24, 1966 [March 31, 1965], No. 13541/65. Heading B4B. Apparatus for transversely or obliquely cutting a longitudinally travelling web comprises a cutter 203, Fig. 11, rotatable about a first axis, with a rectilinear cutting edge 204 inclined to the axis and co-operating with a stationary counter edge 206, or with a cylindrical counter roller rotatable about a second axis of rotation, the counter edge or second axis being inclined at the same angle but in opposite senses to the first axis. In one embodiment a paper web 218 is drawn from a reel 225 by feed rollers 226, 227 which are rotated in timed relation with the rotation of the cutter 203. The web passes between guides 234 and between the cutter 203 and a stationary cutter 205 to a suction conveyer, where the cut web section is wrapped around a block of cigarettes 237. The cutting edge 204 and counter edge 206 are inclined relative to the axis of rotation of the cutter support 201 to effect a progressive cut across the web, and the axis of the support 201 is itself inclined relative to the horizontal to obtain a cut perpendicular to the direction of travel of the web. In a modification, more than one cutter may be provided on the rotatable cutter support, e.g. at each of the four corners of a rectangular cutter support (101, Fig. 6).

The outer conductor is made in sections with soldered V-joints 3 and the stubs 12 are formed to fit into V-shaped notches 25 into which they are soldered. The inner conductor 16 is fitted with T-pieces 31 soldered at the ends 33 and having branches 18 short enough to allow the assembly to be passed through the outer conductor. The struts 15 are then screwed into the branches 18 and the discs 14 soldered to the ends of the stubs 12. In making the T -piece 31, the end of the branch 18 may be shaped to fit a hole formed in the side of the sleeve 19 or a plain end 18<1>, Fig. 6d, on the branch 18 may fit into a cylindrical hole 4 in the sleeve 19 so as to abut on surfaces 41 at the bottom of the hole. The joint is soldered on its outer surface and the part of the branch 18 that protrudes into the sleeve is drilled out. A similar joint may be made to a solid conductor, a flat end on the branch abutting against the flat bottom of a cylindrical hole formed in the side of the solid rod.

Abstract: 1513011 Control of DC motors SIEMENS AG 4 April 1975 [11 April 1974] 13994/75 Heading H2J A dental handpiece 14 is driven by a DC motor M supplied from the output 18 of a power supply apparatus 19 such as that described in Specification 1482943, the motor speed being varied by variation of the supply compressed air to a Bourdon tube 28 which is coupled to the top 27 of a variable resistance 27 and to an ON/OFF switch 26 for the motor. Removal of the handpiece 14 from its location opens a valve 16 to apply compressed air from a reservoir 7 to the tube 28 via a control valve 9 responsive to the position of a foot-operated lever 11, movement of which initially opens valve 9 to cause the tube 28 to open switch 26 to energise the motor and subsequently controls the valve 9 to increase the air pressure and cause tube 28 to vary the position of tap 27 and so increase the motor speed by reducing the impedance of transistors in the apparatus 19, thus increasing the voltage applied to the motor. Members 9, 11 also control the speed of the pneumatic driving motor of another dental handpiece 1 when this is selected instead of the handpiece 14.

Abstract: 1,093,660. Continuous casting. UNITED STATES STEEL CORPORATION. April 2, 1965. [April 15, 1964], No. 14145/65. Heading B3F. In a control system for a continuous casting machine, temperature-responsive means is provided in relation to predetermined levels of molten metal in the mould to effect operation of a cooling spray unit and withdrawing rolls respectively. -Spray units 23, 24 for cooling the casting as it leaves the mould 10 are actuated by temperature-responsive relays 20A, 20B located in the mould wall near the bottom of the mould. The withdrawing rolls are actuated by temperature-responsive relays 40A, 40B in the mould wall near the top of the mould. Time delays means 42A is incorporated in the spray unit circuit to effect a time lag in operation between the commencement of the cooling spray and the start of the withdrawing rolls so as to ensure that the withdrawal rolls do not operate on the surface of the casting until the surface has been sufficiently cooled by the spray, thus preventing rupture of the casting skin. A third temperature-controlled relay means may be included in the system whereby temperature controlled relays 30A, 30B located in the mould wall at the mid-height position effects operation of a mould vibrator and a pump for supplying lubricant to casting surface.

A plurality of cells, e.g. in the form of hollow fibres may be used. The liquid retained by the membrane may be recycled, at least in part, to the hydroformylation. In a modification of the process, part of the liquid remaining after distillation of the aldehydes is recycled to the hydroformylation step and part is firstly treated to separate cobalt and then treated by reverse osmosis to recover ligand and then purged from the system.

Abstract: 189,155. Dreaper, W. P. May 23, 1921. Spinning and doubling machines with twisting- arrangements at delivery; roving and thread guides; spindle apparatus.-Strands of artificial silk or like filaments formed by means of a jet are twisted together in such a. manner that the individual strands receive a preliminary twist before they are twisted together, the strands being positively kept apart until they reach the place where the doubled thread is actually being twisted. Some of the strands may be of. material other than artificial silk or the like, and the strands may be given a small initial twist before they are subjected to the action set out above. The guiding-devices for keeping the individual strands apart may have various constructions. In one arrangement the strands A, Fig. 1, pass from a godet wheel through funnel-topped tubes E, F leading to a lower tube G arranged to deliver the doubled thread into an ordinary centrifugal box D. Liquid supplied by tubes K may be caused to flow down the tubes E, F. In a modification the strands pass from the tubes E, F to a vertically-reciprocating frame Z, Fig. 7, supporting a delivery ring Y in the centrifugal box W.
