Title: Automatic Photographic Printing Machines.
IPC: G03B27/16
Filed: 1916-04-25
Abstract: 100,363. Neff & Lumley, (Assignees of Neff, R. C.). April 24, 1915, [Convention date]. Printing-apparatus. - Relates to an automatic printing-machine for taking prints from negatives or for making enlargements, the exposure and feeding of the sensitive material being controlled by fluid-pressure apparatus. The sensitive matrial K supplied from a roll k passes between the r.egative J and the fluid-pressed rubber diaphragm b, and after exposure is wound up by the lower roller k<1>. The source of light i is contained within a box I and is diffused by the opalescent screen i<1> before passing through the glass slab i<2> and negative J. Fluid (preferably air) under pressure is admitted by the passage a and valve L into the chamber A, divided into two compartments B, C. The fluid passes from the compartment B to compartment C by the passage H and regulable needle valve G, so that the diaphragm D is forced outwards at a predetermined rate. The extent of movement of the diaphragm is regulated by the disk E and rod e<1>, the movement of which to the right is limited by the stop F carried bv the boss N and arms n. The disk E is always pressed towards the left by a torsional spring mounted on the shaft V and attached to the arm v. The shaft V also carries an arm \V with a toothed rack w. In the position shown, an exposure has just been completed, during which the diaphragm D has been moving to the right. At the limit of movement, the switch r is closed, thus energizing the magnet Q and releasing the locking-lever q, whereupon the pressure in the compartment B forces the valve to the right. The air supply is cut off from the passage a, and the air in compartment B is exhausted by the ports a'. The decrease in pressure thus produced on the left side of the valve m causes this valve to open and release the air in the compartment C. The backward movement of the disk E actuates the arm W and sector w so that the roller k<1> is wound up and a fresh strip of material is ready for exposure. At the same time, the pin w<2> pushes the lever P back into its vertical position and thus opens the passage a to the air supply. A spring-pressed brake is provided, which presses upon a drum carried by the spindle of the roller k and, when a new strip of material has been brought into position, is positively actuated by a lever carried by the spindle V so as to prevent overrunning of the roller k.

Abstract: 776,065. Moulding cricket bats &c. LEWIS, J., and RUBBER IMPROVEMENT, Ltd. April 25, 1955 [March .4, 1954], No.6366/54. Class 87(2). [Also in Group XV] A cricket-bat or part thereof is composed of cold- or thermo-setting resins (e.g. polyester or phenolic resins) reinforced by fibrous matererial (e.g. glass, cotton, polyamide, rayon or polyester fibre) which may be woven. The resins may be modified by admixture with other polymerizable materials such as polystyrene, methyl methacrylate or ethyl acrylate. As shown in Fig. 1, two half moulds 1 (made of plaster of Paris, wood or flexible material such as polyvinyl chloride) are lined with the resin into which the fibres are pressed and several layers 2 are thus built up until the desired thickness is attained. The resin is then set, the exposed edges are machined off, the two mould halves are put face to face and the two half bats are joined by application of a layer of resin which is then set. In a modified method a core of cork is covered with resin and fibre and located in a mould in which the resin is set to form the bat. In a further method, a fibrous structure is applied to a thermoplastic core which is then dipped in resin and placed in a mould. When heat is applied to set the resin, the core liquifies and pressure is applied to it to cause it to press the resin against the mould wall. In a modification of this method, the thermoplastic core is covered with the fibrous structure and placed in the mould, liquid resin then being poured between the core and mould. According to the Provisional Specification, hockey sticks or golf clubs may be made by the above methods. Specification 749,614 [Group XV] is referred to.

Abstract: 1393866 Change-speed gear; friction clutches; fluid pressure brakes; full-face disc brake slack adjustment GENERAL MOTORS CORP 14 Feb 1974 [19 March 1973] 6678/74 Addition to 1244719 Headings F2C F2D F2E and F2F In the annular piston 20 and cylinder 16 actuator of the parent Specification 1,244,719, for friction engaging devices such as reaction brakes 46 and clutches in a planetary changespeed gear on a motor vehicle, wherein friction fasteners 56, slidable in one axial direction only on piston posts 31, form abutments for piston retraction springs 29, to retain the latter precompressed so that the piston and cylinder can be installed as a pre-assembled unit in the gear casing 10, the one-way fasteners 56 perform the additional duty of automatic clearance adjusters for compensating for wear of the friction disc pack 46, thereby maintaining a constant engaging travel of the piston and hence constant engagement timing in service. The unit is held in the casing 10 by snap rings 39, 37 the latter supporting, axially fixed, a retainer plate 33 against which bear the retraction compression springs 29, the plate 33 also having, adjacent openings 32 receiving the spring posts 31, pairs of pressed-out wings 64, which accommodate the one-way fasteners 56 and permit only limited axial movement thereof. In operation, fluid pressure, applied at 42, moves the piston assembly 26 leftwards, compressing the brake discs 46 and retraction springs 29, and taking along the friction fasteners 56, which remain fixed on the posts 31 for both apply and release movements. When, due to wear, the apply travel of the piston exceeds the clearance permitted to the fasteners 56 by the wings 64, the outer peripheries 62 of the fasteners contact the wings 64, which arrest the fasteners 56 and flex them sufficiently to permit the posts 31 to slide in them to a new axial position in which the fasteners are retained by pressure of fastener apices 59 against the retainer plate 33 on release, upon which the piston occupies a new position leftward of the former release position, thus ensuring constant apply travel. Abutments 23, 24 prevent piston rotation.

Title: Improvements in the methods of manufacture of electrical resistors
IPC: H01B1/24
Filed: 1950-03-21
Abstract: 671,262. Resistance coatings and deposits. WELWYN ELECTRICAL LABORATORIES, Ltd. (Soc. Anon. De Participation Etrangere). March 21, 1950, No. 6984/50. Class 37. In a process for manufacturing resistors by depositing carbon on an insulating body by the decomposition of a hydrocarbon gas at high temperature (at least 300‹ C.) the insulating body is arranged in a sealed container and relative movement is produced between the surface of the body and the interior of the container so that the body receives a uniform coat of carbon. Fig. 1 shows a furnace comprising a casing 1 in which is arranged a refractory tube 2 on which a winding 3 is arranged. In the tube 2 is arranged a refractory cylinder 4 in which the objects to be carbonized are arranged. The ends of this cylinder are closed by caps 5 to which are attached tubes 6 for passing in hydrocarbon gas or for evacuating, the cylinder. The cylinder rests on cradles 7 at each end. A preferred form of cylinder is shown in Fig. 2 and comprises an outer metal tube 8 closed at one end 9 and provided with a flange 10 at the other end. This end is closed by a plate 11 held by bolts 12 and sealed by a gasket 13. A plate 14 is disposed within the tube and is maintained in fixed position by a rod or tube 15 which is attached to and passes through the plate 11. The plate 14 prevents the objects from being displaced into cooler parts of the furnace. The tube 15 may be utilized to apply vacuum or gas to the objects or for injecting the hydrocarbon vapour or gas from which the carbon is deposited. Vanes 17 are attached to the inside of the cylinder 8 to maintain movement of the bodies being carbonized when the furnace tube is moved or rotated. In a modification, Fig. 4, a paddle 18 passes through the plate 14 and a gastight gland 20 in the cover 11 and serves to keep the objects in motion during the firing operation. The heating means and the container may form an assembly capable of rotation about its axis, or the container alone may be mounted for rotation, the heating means being stationary.
