Title: Improvements in stocks of pistols and like small arms
IPC: F41C23/04
Filed: 1937-01-21
Abstract: 486,139. Automatic pistols. SCHMEISSER, H. Jan. 21, 1937, No. 1826. [Class 119] An automatic pistol is provided with an extensible shoulder piece 4 carried by rods 5 sliding in the stock 3. When the shoulder piece is in the inward position shown in full lines, it lies in a recess 3b in the grip 3a and completes the shape of the grip ; and when moved outwards, it allows a plate 6 guided by bolts 11 to be moved out slightly by springs 15 to complete the shape of the grip. In the extended position of the shoulder piece, hinges 5a in the rods 5 are exposed and enable adjustment of the pistol in relation to the shoulder piece. The rods 5 have recesses 10 near their ends to co-operate with a lever 7 for locking the shoulder piece in its extreme positions. The front end of the stock 3 is hinged at 2a to the magazine casing 2, which is rigid with the breech casing 1. The rear end of the casing 1 is provided with a lug 16 normally locked by a sliding catch 17.

Abstract: 1453439 Catalytic device for exhaust gas treatment T I SILENCER SERVICES Ltd 14 Jan 1974 [13 Jan 1973 3 Aug 1973] 1879/73 and 37064/73 Heading B1F A catalytic reactor for I.C. engine exhaust gas treatment comprises an axial-flow refratory body 6 carrying a resilient wrapping 8, of metal and/or refractory material, enclosed in turn by a split sleeve or by a pair of half sleeves 9, which during assembly are squeezed to compress wrapping 8 prior to sliding the assembly into a rigid casing 1 (Fig. 4). The body 6 is then held firmly in the casing by the resilience of wrapping 8. As shown half sleeves 9 have ribs 10 which taper at one end to assist the half sleeves entry into the casing. Ribs could alternatively be formed on the casing itself. The ends of body 6 engage rings (12) of material similar to wrapping 8, and the axial force to push the assembly into the casing is applied through one of these rings. Figs. 1, 5, 6 (not shown) illustrate the complete device and apparatus for assembling it. The device may be of circular, elliptical, oval or rectangular with curved corners in cross-section. Wrapping 8 could be in the form of half sleeves.

Abstract: 112,999. Booth, T. H. Feb. 8, 1917. Ironing-machines with endless conveying-members; ironing-machines with pressing action only. -A machine for hot-pressing seams, garments, or fabrics comprises a fixed arm C and a. head E, adjustable vertically to give a final ironing- pressure, the material being alternately drawn between and discharged from the pressing-members by endless metal bands H, I maintained hot by contact with the. pressing-members and by passage over heated rollers F, G. The bands are attached to a driving-wheel J having gear segments K, L with either of which a driven pinion M is adapted to enga.ge to feed or discharge the e work. The pinion is mounted on an arm R pivoted on the main driving-shaft P and adjusted by means of a link Z, rod W, and lever V operated by a rockshaft U fitted with a double treadle T. In an intermediate position, the pinion is out of gear with both segments, and the head E may then be lowered to give the stationary pressure. This is effected by raising a runner 4 on a loosely suspended arm 5 into a spiral groove 7 on a conical pulley 8, Fig. 2, by means of an inclined part 3 on a treadle-actuated rod 2. whereby a rod 9 is raised, a shaft 11 is rocked, and brackets 13 carrying the head E are lowered by eccentrics 12. The head E, arm C, and rollers F, G may be heated by compressed air and gas burners.

Title: Electrolytic recording medium
IPC: H04N1/23
Filed: 1961-01-19
Abstract: An electrolytic recording medium comprises a support impregnated with protocatechnic acid in an electrolytically conducting solution.  The support may be white paper.  The conducting solution may be an aqueous solution of a nitrate, chloride or bromide of sodium, calcium, potassium, lithium, magnesium, rubidium, or caesium.  The solution may also contain an acidifier, e.g. sulphuric or citric acid, or a stabilizer, e.g. thiourea, an alkyl derivative of thiourea or dithiobiuret.  One example also includes monosodium phosphate or an antifringing agent.  In use, the medium is passed between and in contact with electrodes one of which contains a metal e.g. iron capable of eroding to supply metal ions to the medium, an electric current is passed between the electrodes so that metal from the one electrode forms ions in the medium and the ions react with the protocatechnic acid to form a grey or black mark on the medium.

Title: Improvements in or relating to lining furnaces
IPC: F23M5/00
Filed: 1954-01-25
Abstract: A lining is applied to the walls of a furnace by blowing into the furnace, at the point where the gases are at the maximum temperature, a refractory powder, which melts at a temperature slightly below the highest furnace temperature, in such a manner that the furnace gases deposit the fused refractory particles on the walls throughout the furnace.  A preferred composition for the powder, which should be fine enough to pass through a 200 mesh screen, is:-45 parts flint, 45 parts kaolin, 56 parts feldspar, 25 parts whiting and 155 parts white lead.  The deposition of this first coating may be followed by a second introduction of a refractory powder of melting temperature higher than that of the powder previously used, e.g. about 3600 DEG F.

Filed: 1923-03-12
Abstract: 210,451. American Laundry Machinery Co., (Assignees of Carroll, E. J.). Jan. 25, 1923, [Convention date]. Interconnecting guard with starting-gear.-An electromotor-driven hydro-extractor of the suspended basket type has a vertically sliding counterbalanced door 40 which controls access to the basket and has an arm 46 to actuate a starting switch 69 in the bottom position of the door. The door is locked in its lowest position by a latch 47 which engages the arm 46 and is released when the solenoid 70 is energized. Connections are shown in Fig. 8 for a three-phase electric motor M driving the extractor. When the basket is at rest and the door is raised a circuit exists through the normally closed contacts 56 and current flows through the indicating lamp 51. When the machine is loaded and the door lowered the arm 46 closes the switch 69. The effect of this is to break the circuit of the lamp 51, to close that of the running lamp 50 and to close the actuating circuits of the motor switches so that the motor starts in the proper direction. In a modification, the machine is driven by a continuous current motor. Specification 210,383. [Class 23, Centrifugal machines &c.], is referred to.
