Title: Improvements in knives and like implements
IPC: B26B1/08
Filed: 1946-12-23
Abstract: 606,631. Knives &c. FOLEY, L. F. G. Dec. 23, 1946. No. 37710. [Class 61(i)] A knife or like implement in which the blade or other tool is housed within the handle and can slide longitudinally to project through one end thereof, in which position it is secured during use, is provided with a lever hinged to the handle so as not to project abruptly therefrom, one end of the lever forming a shutter for the open end of the handle and the other end forming a thumb-piece which can be depressed against a spring to uncover the opening. In the form shown, a partition 16 divides the hollow handle into two compartments containing respectively a knife blade 18 and a marline spike 20. To prevent complete removal from the handle, each tool is provided with an enlarged tang 32 and each compartment with a restricted portion near its open end. Each of the latter openings is covered by a shutter 22 forming part of a lever 23 hinged to the handle at 24, the tail of each lever forming a thumb-piece 26 which can be depressed into a cavity 28 in the handle against the action of a coil spring 30. A groove is provided in each tool to be engaged by the shutter to hold it in projected position. A pair of pins is loosely mounted in the handle between the thumb pieces 26, the length of the pins being such as to prevent simultaneous operation of the two shutters. In a modification, Fig. 10, each shutter is provided with a pair of projections 40, 42 which engage when one shutter is open to keep the other closed.

Filed: 1928-12-24
Abstract: 303,031. General Motors Research Corporation, (Assignees of Almen, J. 0.). Dec. 24, 1927, [Convention date]. Hydraulic transmission of power.-In hydraulic transmission gear, particularly for the valve gear of internal-combustion engines. the hydraulic chamber extending between the working face of the operating member and the working face of the operated member is made sufficientlv small to ensure that the maximum volume of air admitted thereto due to contraction of the liquid on cooling shall be smaller than the displacement volume of the operating-member, so that such air does not materially affect the operation of the mechanism. Fig. 1 shows a cam-actuated plunger 14 connected to a valveactuating plunger 18, the hydraulic chamber 28 between the plungers having a volume about 3¢ times that of the displacement volume of the plunger 14. Oil is supplied to a reservoir 36 between the plungers, the chamber 28 being connected to the reservoir through a hollow plug 37 containing a non-return valve 42. A spring 54 fulcrumed at 56 keeps the plungers 14 and 18 pressed downwards. Surplus oil and air escape from the top of the reservoir by a pipe. In a modification, the tappet 20 bears against the upper end of the plunger 14, the plug 37 is omitted, and the valve 42 is arranged in the top of the reservoir.

IPC: A61F13/04
Filed: 1961-10-30
Abstract: A plaster composition, primarily for use in a plaster of Paris bandage, comprises plaster of Paris intimately mixed with between 0.1 and 10% of hydroxide of an alkali metal, or an oxide or hydroxide of an alkaline earth metal, and between 0.1 and 10% of a finely divided water-repellent organopolysiloxane.  Suitable organopolysiloxanes include those in which the organo group may be an alkyl group, such as methyl or ethyl, an aryl group, such as phenyl, or an unsaturated group such as vinyl or allyl.  Those with methyl groups are normally preferred. The constituents may be mixed dry but it is also proposed to form a slurry of the metal hydroxide and poly-siloxane with unburnt gypsum and subsequently to heat it to a temperature sufficiently high to convert the gypsum to plaster of Paris.ALSO:A plaster bandage comprises plaster of Paris intimately mixed with between 0.1 and 10% of hydroxide of an alkali metal, or an oxide or hydroxide of an alkaline earth metal, and between 0.1 and 10% of a finely divided water-repellent solid organopolysiloxane. Suitable organopolysiloxanes include those in which the organo group may be an alkyl group, such as methyl or ethyl, an aryl group, such as phenyl, or an unsaturated group such as vinyl or allyl.  Those with methyl groups are normally preferred.  The dry constituents, after mixing, may be applied directly to a gauze backing or a slurry may be formed for application to the gauze, but if water is used to form the slurry the application and drying are carried out at above 95 DEG  C. to prevent the plaster of Paris setting.  It is also proposed, however, to form a slurry of the metal hydroxide and polysiloxane with unburnt gypsum and after this has been applied to the gauze to heat it to a temperature sufficiently high to convert the gypsum to plaster of Paris.

Abstract: 1382859 Extruding windscreen wipers DOW CORNING CORP 23 Aug 1972 [20 Jan 1972] 39198/72 Heading B5A [Also in Divisions A4 and B8] A pair of extruded vulcanized elastomeric material sections, each including a metallic web projecting at each side from the material, e.g. a section of a metal backed door or window seal, or of a windscreen wiper blade (see Division A4), as in the described embodiment, is formed by slitting by a knife 26, Fig. 4, an integral extruded section defining a pair of the sections in mirror image relationship. The slit edge may define the wiping edge of the windscreen wiper blade. The webs 13, 14, are drawn into and, within the extruded section, from the die and along the guide rollers through a hot air vulcanizing oven, by a plurality of opposed roller pairs 19, Fig. 3, which engage the projecting web edges in roller grooves 21, 22. The rollers 19 on each side of the section are drivingly interconnected by wheels 24, a motor 23 driving a shaft of a roller 19 on one side of the section, and a shaft of a wheel 24 on the other side to ensure the correct direction of rotation of the rollers 19. The sections may each be coiled for subsequent transverse cutting into wiper blade elements, or the transverse cutting may be effected by a guillotine downstream of the blade 26 and which is actuated from notches spaced along each projecting blade edge, and which notches may also facilitate attachment to the wiper arm. Retention of the webs within the section may be effected by priming agents, or by perforation through the webs as shown.

Abstract: 1,006,652. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Nov. 7, 1961 [Nov. 16, 1960], No. 39293/60. Heading F2F. A tandem master cylinder for hydraulic braking systems is provided with main (2) and secondary (2a) pistons, arranged one behind the other in the bore, and a compression spring 15 is interposed between the adjacent ends of the two pistons and bears at opposite ends against spring cups 19a and 19b abutting opposite ends of the pistons, a rod extending through the compression spring being so interconnected with one of the spring cups and with the other piston or with both spring cups to provide means to maintain the two pistons in axial speed relationship. In the embodiment disclosed in Fig. 1, the rod is in the form of a spigot member 16 extending outwardly from the forward end of the main piston 2 and provided with an enlarged head 17 which is engageable with the end of a cylindrical metal cup 19 projecting rearwardly from the rear end of the secondary piston 2a. An alternative embodiment is shown in Fig. 3 wherein the interconnection takes the form of a rod member 44 retained in spigot portions 41, 42 of pistons 28, 29 respectively by spring cups 40. Under normal operating conditions the two pistons will move jointly when the pedal is depressed against the spring loading on the front piston, the spring loading serving to return the two pistons jointly to the retracted position when the pedal is released. In the event of a fault occurring in the hydraulic brake system connected to the cylinder space of the front piston such piston will be moved to the end of its cylinder whilst the other piston operates the brakes associated therewith. Should a fault occur in the system connected to the cylinder space between the pistons the axial movement of the rear piston will be imparted to the front piston through the mechanical connection provided by the compression spring 15, 39. The embodiment shown in Fig. 1 discloses two separate reservoirs 11, 12 and two separate master cylinder outlets 6, 8. The embodiment shown in Fig. 3 discloses a single reservoir divided into two portions by a partition member 24. Specification 938,185 is referred to.
