Title: Improvements in machines for manufacturing hollow glass articles
IPC: C03B9/22
Filed: 1917-07-10
Abstract: 164,763. Hall, R. F. July 10, 1917. Blowing; gathering molten metal.-Relates to a bottleblowing machine of the Owen's suction type, and consists in apparatus for operating the parison moulds and closely related parts. Fig. 1B shows the upper part of one arm of the machine. The frame 47 carrying the parison mould 52 &c. is hung on parallel levers 36, 37 provided at their inner ends with a counterweight 38. A fixed cam 22, mounted on the central column 16, engages a roller 44, adjustably fixed to the weight 38, and raises and lowers the parison mould 52, to permit gathering, as the arm 28 rotates. The height of each parison mould can be varied independently by a hand-wheel 35, which adjusts the height of a slide 32 carrying the pivots P of the levers 36, 37. The roller 44 is correspondingly adjusted on the weight 38. By this arrangement, moulds of different lengths can be simultaneously used in the same machine. The arms 50, 53, which carry the parison mould halves 52, are operated by link mechanism 57, 58, 62 fitted with a roller 63 engaging a tapered slot 66 in a lever pivoted at 65 to the arm 28 and furnished with a roller 67 engaging the operating-cam 21. The neck rod 71 is withdrawn by a screw S, which is turned at the correct time by a square telescopic shaft 72, operated through rods 78, 79 by a central cam 81. Toggles for opening the neck mould M are similarly operated by a telescopic shaft 87 and cam 82. In a modification, the weight 38 is moved by an electric solenoid instead of by the cam 22 and the parison mould is opened by solenoids instead of by the cam 21. The parison mould mechanism described above, and also the corresponding finishing-mould mechanism, are carried by a double column C which is secured at the top to the arm 28 and at the bottom to a rotating ring mounted on a ball bearing. By this means a complete set of moulds &c. can be removed from the machine as a single unit for repair and replaced by a fresh unit. Specifications 164,763, 165,799, and 165,800 are referred to.

Title: Improvements in the reproduction of sounds accompanying motion pictures
IPC: G03B31/00
Filed: 1928-05-16
Abstract: 319,197. Whitehorn, H. A. May 16, 1928. Systems for transmitting music &c.-Relates to apparatus for reproducing sound accompanying moving pictures, of the kind in which several loud-speakers are arranged in different positions adjacent to the picture-screen. According to the invention, all the loud-speakers employed are adapted to be operated simultaneously from a single soundrecord by means of a single piclc-up influenced by the record, and means are provided whereby the frequency components of the sounds are discriminated against differently in the various loud-speakers, so that the higher frequencies appear to come from one point in or adjacent to the screen, and the lower frequencies from another point. This result is preferably obtained bv the use of filter-circuits, each associated with a loudspeaker of appropriate construction. The sound reproducing device R, operating synchronously with a kinematograph projector P, is connected to an amplifier A, the output of which is distributed through a controlling panel C to loudspeakers L', L<2>. The horn of the loud-speaker L<2> is situated behind the upper part of the porous screen S, and the horn of L<1> is located in the orchestra pit. By using suitable net works 10, 11 of inductances and capacities, in the circuits of the loud-speakers, it is arranged that the loudspeaker L<1> shall emphasize the lower frequencies in the reproduced sounds, whilse these frequencies are attenuated in the reproduction by the loud-speaker L<2>. The attenuations are preferably complementary to each other. The networks employed may be of the types described in Specification 202,284. The panel O may be provided with volume-controlling devices and with means for disconnecting one of the loud-speakers.

Title: An improvement in or relating to vehicle suspensions
Inventor: WALSHAW TERENCE
IPC: B60G21/00
Filed: 1969-03-19
Abstract: 1299436 Vehicle suspensions; undercarriages T WALSHAW 26 Feb 1970 [19 March 1969] 14484/69 Headings B7D and B7L A vehicle has a wheeled chassis connected to a load-carrying body by a universal joint whose point of action is substantially at the same height as the centre of gravity of the loadcarrying body, the universal joint being constrained to allow angular movement and only substantially vertical linear movement between the body and chassis by virtue of coupling between adjacent wheels on the chassis. In one embodiment (Fig. 1), transversely extending pivot 14is common to two longitudinal beams 10, 12 carrying the vehicle wheels. Coil springs 28 are disposed between the beams and the body 24. The latter has secured thereto a ball 18 rotatable on a spindle 20 which bridges an aperture in, and is secured to, the body. The ball 18 is located in a mounting upstanding from the member which carries the pivots for beams 10, 12. Slots 26 receive the spindle. During cornering transverse forces acting between the body and chassis are taken through the ball joint so that lateral canting or movement is prevented. Similarly squat and dive are prevented. In another embodiment (Fig. 3), a longitudinal chassis member 100 supports fore and aft frames 102 to which independent wheel-supports arms 108 are pivoted. The arms 108 are also pivoted to longitudinal beams 110, 112 which have a common transverse pivot axis 114. The mounting 116 of the beams comprises a stirrup member 120 located against fore and aft movements relative to chassis member 100. A ball 118 extends from chassis member 100 through stirrup member 120 and into socket 138 in the vehicle body at the centre of gravity of the latter. The connection of the socket 138 to the vehicle body includes leaf springs 140. As opposed to a motor road-vehicle, the vehicle could be a rail vehicle; also the ball joint could be replaced by a linkage whose function simulates that of the ball joint.

Abstract: 492,984. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. May 28, 1937, No. 14852. Convention date, July 1, 1936. [Class 40 (v)] volume expansion in a low frequency amplifying valve L the bias of a gain control grid 7 is varied by the voltage developed across the load resistance 3 of a diode 2 fed with the signals. The gain control voltage is applied to the grid 7 over two parallel paths comprising a diode 19 in series with a low resistance 20 and a high resistance 21. When the bias is becoming more positive the diode 19 is conducting and the time constant of the control path is small but when it is becoming more negative the diode 19 becomes nonconducting and the path 21 only is operative with a large time constant. Said time constants depend also on the capacity of condenser 6 connected between the grid 7 and earth. The Specification as open to inspection under Sect. 91 comprises also a circuit omitting the alternative time-constant network and providing a potentiometer 23, Fig. 3 (Cancelled), for adjusting the amount of expansion by varying the input signal to the diode 2 which is ganged to a potentiometer 25 which adjusts the mean potential of the gain control grid 7 of the amplifier L. In this way the bias on grid 7 is made more negative with increasing expansion control and has the effect of suppressing weak signals such as parasitic noises. This subject-matter does not appear in the Specification as accepted.
