Title: Improvements in or relating to fluid-compressor unloading-valves
IPC: F04B49/24
Filed: 1934-12-07
Abstract: 431,112. Valves for compressors. MOSS, E. W., 75, Victoria Street, London.- (Ingersoll-Rand Co.; 11, Broadway, New York, U.S.A.) Dec. 7, 1934, No. 35232. [Class 8 (i)] [See also Group XXIX] A compressor unloader comprises radially arranged valves which on the attainment of the desired pressure are positively opened by the action of an auxiliary valve which admits fluid under pressure to a diaphragm actuating spring- pressed member to carry pivoted arms into contact with the valve closing-plates. In Fig. 1, the valves consist of slots Q formed in a cylinder O and normally closed by plates S, and constitute the inlet valves of the compressor cylinder C. At each suction stroke of the piston E the valves open inwardly against the action of plate springs T supported by a slotted cylinder U. When pressure in the storage receiver reaches the predetermined value, a valve in a conduit 44 admits fluid from the receiver to the chamber f above a diaphragm g which rests on a member j pressed upwards by a spring 6 housed in a cavity in a fixed filler - member X. The member j is thus depressed, carrying the outer ends of bellcranks s, pivoted to the member j at r and fulcrummed at their inner ends w in the fixed member X, into contact with the valve-plates S, thereby maintaining the valves open during both strokes of the piston E. The bell-cranks may be replaced by pivoted arms moving downwards in contact with stationary cams, Fig. 4, (not shown). In Fig. 5 (not shown), the spring 6 is replaced by leaf springs acting on the bell-cranks.

Title: Improvements in and relating to electric ironing machines
IPC: D06F67/10
Filed: 1937-12-20
Abstract: 489,474. Ironing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 20, 1937, No. 35297. Convention date, Dec. 19, 1936. [Class 138 (ii)] In an ironing-machine wherein the ironing is effected by the rotation of a roller 32 in contact with a concave shoe 3, the roller is provided with an internal sleeve 39 freely surrounding an eccentric 41 journalled on a stationary tube 19 coaxial with the roller and secured at one end in the gear housing (not shown). The eccentric is secured to a shaft 18 extending through the tube 19 and having a constantly rotating worm wheel 17 and integral pinion 21 mounted loosely thereon. When the worm wheel is clutched to the shaft, by the actuation of a lever 60 by the knee of the operator, the shaft is rotated to raise the roller into operative engagement with the shoe and the clutch is automatically thrown out after the shaft has rotated through 180‹. An internally-toothed wheel 42 within the roller has now engaged the pinion 43 driven by the constantly moving pinion 21 so that the roller rotates in contact with the shoe until the shaft 18 is again clutched to the worm wheel when the roller is moved out of contact with the shoe and the drive broken. The roller may be held stationary in contact with the shoe by the manual actuation of a lever 30 which throws out one of the gearwheels 22 in the train between the wheels 21 and 42. Coacting members 44, 45 prevent jamming of the gears. Rotation of the roller during its movement into contact with the shoe is prevented by providing an intermediate sleeve 40 between the eccentric 41 and sleeve 39 with a tongue 68 which engages a radial slot 69 in a disc 70 secured to the tube 19. The shoe is yieldingly supported by rods 78 secured to a hinge member at the top of the gear casing whereby the shoe can be raised for cleaning. In a modification, a manually actuated handle is provided for rotating the roller out of contact with the shoe in case of failure of the power supply, and in this form the hinge member is omitted and the rods 78 are slidingly mounted in the top of the gear casing so that one may be completely withdrawn and the shoe swung about the other rod when required for cleaning.

Abstract: 1,057,314. Filing papers. F. SOENKECKEN. Sept. 11, 1963 [Sept. 12, 1962], No. 35889/63. Heading B6E. A locking-follower 1 for engagement over the filing posts of a letter file comprises metal or synthetic resin member of U- shaped cross - section beneath which two clamping wires 2, 3 are mounted by means of lugs 4, 5 and strips 6, 7, the ends of the wires protruding across holes 8 through which the filing posts pass. A central hole 9 receives a press-button 11 having a shank which is recessed centrally, tapered inwardly towards the button, and formed with a lower grooved part which merges into a bottom rim. Initially, downward pressure on the button 11 causes the wires 2, 3 to be pressed apart and then engage the central recess, whereby the wire ends are caused to approach one another and clamp against the filing posts in the holes 8. To release the wires from their clamping position, the button 11 is merely tilted in any direction. Fig. 5 shows the button tilted transversely of the locking- follower so that the wire 2 slides into the lower groove of the shank: this causes a tilting of the shank and a raising of the button so that the wire 3 also engages the lower groove. In this position, the wires are not flexed centrally, and therefore their ends do not exert pressure on the filing posts. The button 11 is made partly or wholly of synthetic material.

[Also in Division H4] In an answer-back device the identification signal is generated by coded discs which are driven such that their speed ratio is m: n, m and n being mutually prime. The device includes means for sampling received signals and for short start suppression. Answer-back generator, Fig. 1.-Disc D4 is mounted on the same shaft as timing disc D1 which, through a 150: 149 reduction, drives disc D3, which provides the identification signal pulses, and D2, which provides the identification signal. This signal comprises twenty 7¢. unit signals. When toggle 4 is switched On as above and pulses from D3 and D1 coincide toggle 5 is put On, opening gate 11 so that counter 6 counts the D1 pulses. When the counter reaches 7 toggle 4 is switched Off and the counter resets whereby gate 15 switches toggle 7. The identification signal from D1, to gather with the resetting signal from counter 6 cause toggle 7 to be switched On and Off, thereby transmitting the signal. The arrangement of the notches on the wheels D1-D3 is such that the twenty characters are transmitted successively, after which a pulse via gate 12 switches toggle 5 Off so that the device is put at rest. Counter, Fig. 3.-Counter 6 is a binary gated counter which counts to seven during transmission of the identification signal and to five during reception of the combination bits of a start-stop signal. The scale is selected by a signal at 5R, and the counter automatically resets when full.

Abstract: 156,582. Rheinische Metallwaarenund Maschinenfabrik. Jan. 6, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Addition to 155,762. Buffers.-In a buffer for railway vehicles of the type described in the parent Specification, the plate supporting the spring abuts against inwardly bent projections formed from material of the inner telescopic tube and the range of movement of the spring and inner telescopic tube is limited by projections bent out of material of the outer tube. The tubes a and b have inwardly bent projections e1, e2 respectively of which e1 engages with a guiding slot cut in the inner tube b, and e2 with the plate g supporting the spring k. The projections e1 are cut away when the inner tube b has to be withdrawn and on replacement others are made further round the circumference. In a modification, the tube a terminates at the projections e1 a number of extensicns being left on for future use. A sight hole may be cut in the outer tube for inspection of the spring k. In a further modification, the projections e1, e2 do not perforate the tubes but may be a number of bentin portions of an annular ring; the projections on the outer tube are situated near the headstock end of the tube forming a stop against which the flared out end of the inner tube is arrested and which limits the outward movement of the inner tube. The bent-in portion of the inner tube acts as an abutment for the plate supporting the sprifig. The outer end of the tube a is constricted and forms with the flared out ends of the inner tube b the guiding surfaces of the buffer. When dismantling, the rivets securing the buffing face c to the inner tube have to be removed as well as the bolts in the buffing-plate l.
