Title: Improvements in or relating to centre-posts for gramophone record-changing apparatus
IPC: G11B17/16
Filed: 1960-09-21
Abstract: 955, 341. Gramophone centre-posts. ELECTROACUSTIC G.m.b.H. Sept. 21, 1960 [Sept. 21, 1959; Jan. 28, 1960], No. 32472/60. Heading G5R. A symmetrical support-and-clamp centrepost, shown in the unloaded state comprises a set of supports 46, retractable into an actuator 36 which engages them at 45 and a set of clamps 56 engaged in a ring 61, slidable under the influence of a spring 62 on the actuator 36 to an extent limited by a stop-collar 64. The weight of a stack of records placed over the post lowers the supports 46 against the action of a further spring (Fig. 5 not shown), the spring 62, together with co-operating cam-surfaces 58, 59 urging the clamps 56 outwardly into engagement with the centre-hole of the lowest-but-one record, the clamps being profiled at 70 to ensure effective clamping, even when the clamped record has an oversize centre-hole. Further downward movement of the actuator 36 engages the cam-surfaces 51, 52 to release the lowest record to the turntable, the innate inertia and the timing of the assembly being such that on rebound, the surfaces 69 engage the interior of the post to release the clamps momentarily, allowing the now-lowest record to fall on to the re-extended supports 46. When the last record has been released, the assembly, aided by the action of the surfaces 69, rises to the position shown, carrying with it a rod 65 associated with means to switch off the motor when the record has been played.

Title: Improvements in or relating to glass cutting machines
IPC: C03B33/033
Filed: 1964-08-10
Abstract: <PICT:1002485/C1/1> A machine for cutting flat glass in ribbon or sheet form, travelling at a substantially constant speed comprises a pair of parallel supporting rollers 3, 4 whose axes are parallel and are at right angles to the direction of travel, f1, of the glass, a plurality of pressure wheels 8 mounted above the glass with their axes in alignment with one another and parallel to the axes of the supporting rollers 3, 4, and a breaking device 6 rotatable about an axis parallel to the supporting rollers and having at least one projecting member 7 parallel to the axis of the breaking device, the breaking device 6 being positioned so that the projecting member or members bend the glass overhanging the downstream supporting roller so as to break off the overhanging portion along a previously made score line.  The breaking device is preferably a roller having one or more rubber-faced projecting members 7 extending along generatrices of the roller 6, the axis of the roller being further from the plane of the glass sheet than the radius of the roller and the radial dimension of the projections 7 sufficient to break the glass during rotation of roller 6. A sheet 1 is fed on to the supporting rollers 3, 4, then under soft rubber-tyred pressure rollers 8, and then under the stationary breaking roller 6 to overhang support roller 4.  A previously made score line passes through the beam of a sensing device 9a-9b and sets the breaking roller 6 in motion at the same speed as the forward travel of the glass sheet.  The sensing device is preferably fixed at the same distance upstream of the support roller 4 as the length of arc b1 prescribed by a projecting member 7 before contacting the sheet.  Thus the score line is vertically above the axis of the roller 4 when the member 7 contacts the glass and makes the break.  If strips of glass wider than say 10 cm. are to be cut, the pressure rollers 8 may be downstream of the support roller 3, but if strips less than 10 cm. are required, the rollers 8 are placed upstream of roller 3.  This is so that there is still a sufficient tolerance if the break is made when the score line is slightly to either side of the vertical plane through the axis of roller 4.

Title: Polarization independent light modulation means using birefringent crystals
IPC: H01S3/11
Filed: 1971-07-12
Abstract: 1363143 Modulating light WESTINGHOUSE ELECTRIC CORP 12 July 1971 [28 Aug 1970] 32519/71 Heading H4F [Also in Division H1] A modulator for use with incident light 1 of any polarization comprises a birefringent crystal 2 providing parallel E and O output beams, a polarization switch 4 generally of the type described in Specification 1,066,612, Fig. 2 (not shown), and a second birefringent crystal 3 which serves to recombine the E and O beams into a single beam 6 when switch 4 is inoperative. When switch 4 is operative to change the plane of polarization of the incident beams by 90 degrees, to O<SP>1</SP> and E<SP>1</SP> beams, crystal 3 serves to further separate the beams so that they are equidistant from the axis of beam 1, so that the intensity of-the light transmitted along this axis is varied. A laser, Fig. 6, including an active rod 12 between a mirror 9 and half mirror 8, also includes a birefringent crystal 17 and polarization switch 18, equivalent, when reflection from mirror 9 is included, to the system 2, 3, 4 of Fig. 1A, and acting as a Q-switch for the laser. When a quarter wave voltage is applied to switch 18, i.e. a 90 degree polarization change on a double pass, the reflected beam leaving crystal 17 is deflected and optical feedback to rod 12 is prevented.

Title: Improvements in or relating to self-propelling pencils
IPC: B43K21/22
Filed: 1927-12-05
Abstract: 307,324. Barberon, P., and Pons, C. Dec. 5, 1927. Pencil holders.-In a pencil holder, the point, through which the lead passes frictionally, is axially movable in the casing and is connected by the lead-guiding tube to the operating-head, and a clamp, which serves only to hold the lead in stationary position in the holder, is provided, the lead being released by the clamp during the operation of the mechanism and allowed to fall by gravity, but being re-engaged and prevented from rearward movement by the clamp before the nozzle completes its return movement. The piece of lead which is engaged by the clamp is distinct from that engaged by the nozzle. The leads are fed from a chamber 7 to a lead-guiding tube 5 which is formed with diametrically-opposite slots 9 housing a clamp 13, Fig. 1, the jaws 14 of which tend normally to grip the lead. The clamp is movable between abutments 3, 4 in the holder, but its range of movement is less than that of the tube 5. The tube 5 is formed with a conical portion 11 at the upper ends of the slots 9. In operation, the chamber 7 is pressed inwardly, and carries with it the tube 5 and nozzle 8. The lead m, held by the nozzle, is also drawn forward, and the clamp, with an upper lead m<1>, moves forward as far as the abutment 3. The lead mis drawn further forward during the continued movement of the nozzle 8, but the lead m<1> is held until the jaws are opened by the conical part 11 of the tube 5 when it falls into contact with the lead m<1>. On the return of the tube 5 under the action of the spring r, the clamp moves with the tube until it encounters the abutment 4, when the jaws are released from the part 11 and again grip the lead m<1>. During the completion of the return movement, the nozzle 8 is retracted to uncover a small portion of the lead m. In a modification, the jaws 14<1>, Fig. 8, are free and are forced into engagement with the lead by a conical member 22 carried by a tube 23 frictionally slidable in the holder. The jaws engage a stop 20 under the influence of a spring 21, the stop being formed with a slightly conical face to facilitate the opening of the jaws. When the mechanism is actuated, the member 22 and jaws are fed forward until arrested by a shoulder on a fixed stop 24. On further movement of the tube 5, the conical part 11 pushes the jaws clear of the member 22 and opens them to permit the lead to fall. On the return movement, the jaws again grip the lead before the completion of the movement of the nozzle 8. If excess pressure is applied to the point of the lead, it can, together with the jaws and member 22 recede into the casing against the action of the spring 25.

Title: Improvements in or relating to astable multivibrators
IPC: H03K3/282
Filed: 1966-07-22
Abstract: 1,147,219. Astable multivibrators. SIEMENS A.G. 22 July, 1966 [23 July, 1965], No. 33002/66. Heading H3T. In an astable multivibrator a circuit is connected to the output electrodes of two amplifier stages T1, T2 of the multivibrator to derive a control signal which is applied asymmetrically to one input to change the state of one of the amplifier stages if the multivibrator fails to oscillate. As shown, if on starting transistors T1 and T2 both turn on, the network consisting of diodes D1, D2 and resistors R1, R2 allows diode D3 to conduct and connect a negative potential to the base of transistor T1; transistor T1 is turned off and the multivibrator starts, and continues to oscillate due to the normal cross-coupling capacitors C1, C2. When the multivibrator is oscillating the potentials applied to the diodes D1, D2 are such that the diode D3 is reverse biased. In an alternative arrangement (Fig. 2, not shown), a transistor (T3) is connected between the resistor R2, point A and the supply +U and is arranged to conduct so as to reverse bias the diode D3 during normal oscillation of the multivibrator.
