Title: A method of forming an agglutinated fibrous material suitable for padding or air filters
IPC: C08J5/14
Filed: 1947-03-17
Abstract: 648,377. Agglutinated fibrous material. HOUDAILLE-HERSHEY CORPORATION. March 17, 1947, No. 7336. Convention date, Aug. 30, 1946. [Class 140] A method of forming an agglutinated fibrous material suitable for padding or air filters wherein fibres are fed to a batt-forming mechanism, a bonding agent is sprayed on the fibres and air pressure is applied to the fibres upon arrival at the batt-forming location, is characterized in that the air pressure is regulated to control the density of the resultant bath. The material may be supplied in the form of a sliver which may be crimped, cut into short lengths and carded before being delivered to an oscillating shoot and formed into a batt, using apparatus identical with that described in Specification 648,380, or alternatively the fibrous material may be delivered from a shoot 40 into a mould 36, the air and bonding material, preferably a vinyl resin, being applied from a pair of atomizing nozzles 41. The moulds 36 are rotatably mounted on a table 29 which is journalled in a pedestal 28 and intermittently rotated by a motor 30. As each mould comes beneath the shoot 40, the table 29 remains stationary whilst the batt is formed. A spur-wheel 39 mounted on the shaft 38 carrying the mould engages at this point a wheel 34 driven from a continuously-operating motor 32 so that the mould is rotated to ensure uniform packing of the material. The pressure of the air from the spray which may be varied, regulates the density of the finished batt, the bottom 37 of each mould being perforated to allow the passage of air. To form a hollow cylindrical batt, a core may be placed in the mould. The fibrous material may be metal, or of animal or vegetable origin, and prior to being brought to the batt-forming location may be impregnated with a water solution of ammonium sulfamate to render it flameproof.

Title: Adjustable steering column assemblies in motor vehicles
IPC: B62D1/18
Filed: 1967-02-16
Abstract: 1,103,940. Adjustable steering wheels. GENERAL MOTORS CORPORATION. 16 Feb., 1967 [17 March, 1966], No. 7381/67. Heading B7H. A motor vehicle has an adjustable steering column assembly including a release member 32, for allowing adjustment of the tilt of the steering wheel, which is operable manually or, on opening of a door 26 adjacent to the steering wheel, through an actuator mechanism which is sensitive to opening of the door and produces axial displacement of a member 42 which extends between the door assembly and the release member. The steering wheel is carried by an upper column portion 6 which is pivotable about a transverse vehicle axis 8, is biased towards its uppermost position by a pair of springs (24) (Figs. 3, 4, not shown), extending between the column portions 4 and 6 and is held in one of a number of incremental positions of tilt by one of a pair of spring-biased latch members 10, 12 which have notches alternately engageable with pins 20, 22 of the lower column portion 4 and which are releasable by movement of a release element 32 towards the vehicle driver by a manual control arm 14. The release element 32 is also actuated, thereby allowing the springs 24 to raise the steering wheel to its uppermost position, when the door 26 is opened by a sheathed Bowden cable 42 having one end connected to a pin 44 on the release element 32 and the other end provided with a reciprocable plunger 46 movable in the end 36 of the sheath 38 by the end 68 of an arm 52. The arm 52 is connected to, and rotates about a pin 56 with, an arm 54 having a serpentine slot 62 engaged by a pin 64 of the door hinge 66. The arms 52 and 54 are inter-connected by a pair of spring-loaded interengaging ramped ribs (76) and slots (78) (Figs. 7, 8, not shown), which disengage when a spring 48 on the plunger 46 is compressed permitting the spring to return the plunger to its original position and the latch 10 to hold the steering wheel in its uppermost position. When the door is closed the ribs (76) and slots (78) re-engage.

Title: Improvements relating to cinematograph cameras
IPC: G03B19/18
Filed: 1945-03-23
Abstract: 619,851. Control of motors. AVIMO, Ltd., and STEVENS, H. C. M. March 23, 1945, No. 7402. [Class 38 (iii)] [Also in Group XX] A control system for a kinematograph camera comprises a switch (not shown) which energizes the motor d and a solenoid e to remove the latch f from a notch in the disc a driven by the motor and having a projection m which opens contacts i, normally closed, when the latch is in the notch. The contacts are in parallel with the switch so that after the motor has been started it runs until the contacts are opened by the projection m, when the latch f is again engaged. One revolution of the disc a corresponds to the exposure of one film frame. Thus, momentary closure of the external switch produces single exposure and sustained closure a kinematograph sequence. The external switch may be as described in Specification 619,936.

Abstract: 737,815. Piezo-electric crystal holders. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 8, 1954 [March 17, 1953], No. 7409/53. Class 40 (8). A quartz piezo-electric crystal bar 6 is supported by two symmetrically arranged support systems 7, Fig. 2, one on each side of the bar, the support systems spanning part (preferably at least 30 per-cent) of the bar near a nodal line in order to prevent twisting. The support systems comprise V-shaped phosphor bronze wires 7a soldered at 7c to the opposite faces of the crystal and at the apex to parallel longitudinal supporting rods 4 which, together with mica discs 5, form a cage fitting within a glass envelope 1. The rods 4 are joined to leads 3 which pass through the pinch 2 of the envelope. The crystal may be a 0 degrees, + 5 degrees or - 18.5 degrees X-cut bar and may be mounted on the centre line CL or on the nodal line NL when centre-line mounting results in an unacceptable increase in series resistance. For the - 18.5 degrees X-cut bar the centre and nodal lines coincide although the frequencytemperature coefficient is higher than for the 0 degree and 5 degree cuts.

Filed: 1927-03-17
Abstract: 267,953. Klimsch, E., and Schumacher, P., (trading as Klimsch & Co.). March 22, 1926, [Convention date]. Photo-mechanical printing-surfaces; printing-apparatus.-In a process for printing from an ordinary negative in conjunction with a half-tone screen, the screen is independently printed either before or after the main exposure through the screen and negative. For the independent exposure of the. screen, a sheet of glass or foil equivalent in thickness to the negative may be interposed. To accurately position the screen for the two exposures, the screen may be mounted on a heavy frame B hinged at C and counterbalanced by a releasable counterweight E. A gear G is provided for bringing the sensitive plate up to any prescribed level and levelling screws H are also provided. A guard plate I protects the screen against dropping particles of ash or carbon. The process obviates long exposures through dense negatives or the use of thin negatives, and is particularly suitable for making photo-lithographic surfaces, as well as for making stereotype plates and plates for newspaper type. According to the Specification as open to inspection under Sect. 91 (3) (a), the apparatus may be used for ordinary printing by substituting a plane glass plate for the screen. This subjectmatter does not appear in the Specification as accepted.

Plasma is generated and/or accelerated in a tube 24 of insulating material by applying a current pulse to an induction coil 23 surrounding a region wherein a cusp field is generated by two field coils 21 and 22 mounted on the tube 24. A spark gap 26 is triggered by an ignition device 25 to complete the circuit of the field coils 21, 22 and to trigger a spark gap 27 in the circuit of a probe 210 for measuring the product of the velocity and conductivity of the plasma. The voltage induced in the measuring coil of the probe is passed through a delay device 29 to trigger a spark gap 28 and complete the circuit of the induction coil 23 when the fields of the coils 21, 22 have reached their maximum value. A number of the " plasma gun " arrangements may be mounted around a toroidal insulating tube (Fig. 3, not shown) to produce theta pinch and static and dynamic reflector and cusp fields capable of effecting simple and multiple plasma accelerations and reflections. An iron core may be located between each two field coils (Fig. 4, not shown) to produce a toroidal Z-pinch.
