Abstract: 1366257 Apparatus for forming packed refuse blocks K TEZUKA 21 Nov 1972 53802/72 Heading B8C An apparatus for forming compacted and packed blocks from loose refuse comprises, in combination, compressing means including at least one chamber 7 for receiving loose, or pre-compressed, refuse and having an outlet 13 for discharging a block compacted from the refuse, a compression container 15 having one side pivotally secured in the vicinity of said outlet of the compression chamber and adapted to receive the compacted block, means 24, 25 for imparting a quarter of a turn of pivotal movement to said container so as to establish substantially rectilinear communication with said compressing means in one of the operational positions, locking means 30, 34 for optionally interconnecting said outlet with an inlet of said container in said one operational position, and means 40-46 for packing a sheet, or like material, about the compacted block. As shown, refuse is dumped into an open-topped, compression chamber 1 where a ram-operated pressure plate 2 compacts the refuse against an end plate 6 which is withdrawable upwardly by a ram 10 for transfer of compacted refuse to the compression chamber 7 in which a second, ramoperated, pressure plate 12 compacts further the transferred refuse as the latter is urged into the compression container 15 which is clamped in line therewith and which is internally lined with a layer of packaging material such as wire netting, or polyethylene. The container 15 is pivoted, at 22, to the chamber 7 and is rotatable by the ram 24, 25 through substantially a quarter of a turn from the filling position where it is secured by ram-operated clamps 30, 34 into a horizontal position over the outlet 13 of the chamber 7 to a substantially upright position as shown in dotted lines, Fig. 2. Bell-crank levers 60, Fig. 5, acting through slots 61 in the side wall of the container 15, are swingable individually by rams 64, 65 inwardly and downwardly within the container 15 to fold down the upper end of the packaging line F. A base-plate 17 transversely slidable in an opening 15b in the container 15 is movable by a ram 50, 51 to bring an opening 18 in the plate 17 into coincidence with the outlet 13 of the chamber 7 so that a further extension of the plate 12 ejects the packaged refuse from the container 15, and an arm 41 is then swung horizontally by a ram 47, so that a block 44, carried by a vertically reciprocable ram at the free end of the arm 41, is located directly above the container opening. Actuation of the ram 43 lowers the block 44 into the container 15 to spread the packaging material evenly around the inside wall of the container.

Title: Hydromechanical steering transmission
IPC: B62D11/10
Filed: 1973-04-20
Abstract: 1438297 Endless-track vehicle transmissions GENERAL ELECTRIC CO 20 April 1973 [20 April 1972] 54835/72 Heading B7H [Also in Division F2] A hydromechanical transmission suitable for tracked vehicles provides three forward speed ranges by selective brake and clutch energization, and reverse range and steering function by adjustment of the displacement of pump/motor combinations. As shown, first range is established with a clutch E, Fig. 1, and a brake D disengaged and a brake C engaged. Power is then transmitted through gears 12, 15, 17 to variable displacement pumps 18A, 20A which are hydraulically connected to fixed displacement motors 18B, 20B which drive sun wheels 23a, 25a meshing with planets on carriers 23b, 25b driving the right and left outputs 14, 16, ring gears 23c and 25c being held by their engagement with gears 42, 52 on a shaft 44 arrested by the brake C. The motor 18B drives the wheel 23a through a planet carrier 21b of a differential gear comprising pairs of intermeshing planets of which one planet of each pair meshes with a ring gear 21c and the other with a sun wheel 21a on a shaft 19 rigid with the sun wheel 25a. Speed in first range is increased by increasing the displacement of the pumps, and when these reach approximately 80% of their maximum displacement a train comprising the ring gear 21c, idler gear 41, gear 40 and integral sun gear 36a, planet carrier 36b, sun-wheel 28a on the input shaft 13, and ring gear 28c results in the latter coming to rest, whereupon second range can be established by engagement of brake D and release of brake C. Increase of speed in this range is effected by reduction of pump displacement resulting in power being transmitted partly by the pump/motor units and partly through the train 28a, 28b, 36b, 36c, 38, and the gears 42, 52 driving the ring gears 23c, 25c. When the displacement of the pumps has passed through zero and increased to approximately 80% in the opposite sense a shaft 48 driven through gears 52, 50 will be running at the same speed as the shaft 13 and third range can then be established by engagement of the clutch E and release of the brake D. Speed in this range is increased by bringing the displacement of the pumps back through zero to maximum displacement in the first sense. Steering is effected by differential adjustment of the displacement of the pumps, and reverse drive, during operation in the first range, by reversal of the sense of displacement of the pumps. The pumps and motors comprise rotary bodies 59, 60, Fig. 2, with radial cylinders interconnected by passages 68, 69 in a stationary pintle 66 and containing ball pistons 57, 58 coacting with fixed outer races 75, 76, the eccentricity of the pump races 75 being adjustable by fluid-pressure servomechanisms. The eccentricity of the motor races 76 may be fixed or adjustable.

Abstract: 1,205,466. Recording and playback. A. E. DUBORD. 19 Nov., 1968 [9 Jan., 1968], No. 54897/68. Heading G5R: Information is retrieved from a prerecorded medium 17 by moving an instrument at an arbitrary speed over the medium to pick up the information and transfer it to an intermediate store in the instrument. The information is subsequently played back from the intermediate store at a speed substantially equal to the original recording speed of the medium 17. As shown, the prerecorded medium 17 is in the form of strips of magnetic tape incorporated in the pages of a book with corrugations 20, Fig. 5, to guide the reading instrument. This contains, Fig. 1, a pick-up head 7 connected through an amplifier to a record/playback head 15 which co-operates, together with an erase head 16, with a magnetic coating 2 on an endless belt 5 of rubber or the like which is driven directly or indirectly (Figs. 2, 2a and 4) by friction with the tape 17 as the instrument is moved along the tape. The recording circuit is completed by closure of resilient switch contacts (19, Figs. 3 and 6) when the reading instrument is pressed against the tape 17. Insertion of the instrument into a playback unit 33, Fig. 5, actuates other switches (39, 42, 44, 47, Fig. 6) to complete .a playback circuit, including a loud-speaker 49, and set in motion a wheel (45, Figs. 4 and 6) which drives the intermediate storage belt 5 at a speed substantially the same as that at which the tape 17 was driven during the original recording process.

Abstract: 550,536. Soot-blowers. BABCOCK & WILCOX, Ltd., and GLINN, R. J. July 10, 1941, No. 8753. Addition to 532,692. [Class 99 (ii)] In a fluid-heater cleaner having a retractible blower element, and a main valve for admitting the cleaning-fluid arranged to be opened by the action of the fluid on a piston as controlled by a relay valve, as described in the parent Specification, means are provided whereby the main valve is actuated mechanically if the fluid-pressure actuation should fail. In the form shown in Fig. 1, the blower element 1 is movable along a bore 5 to which cleaning-fluid is admitted by a main valve 16 connected to a piston 7 operating loosely in a cylinder 6 and providing a seat for the relay valve 8 operated by a cam 26 in the blower element, when this is brought into line with a tappet 27 actuating the valves through levers 127, 131. When the relay valve is opened, the pressure above the piston 7 is evacuated into the blower element through a bore 115, and the piston is raised to open the main valve. If the latter should stick, the relay valve engages a bridge piece 121 secured to the piston, and opens the main valve mechanically. In a modification the relay valve seats on the main valve, and a pin on the stem of the relay valve engages the piston, both valves and the piston being arranged axially with the inlet 132 for the cleaning-fluid.
Patent GB-550547-A (GB)
Abstract: 550,547. Interrupters. DRUMMOND, C. T. Sept. 4, 1941, No. 11302. [Class 38 (v)] Rotation of a disc 1 having one or more recesses or projections 20 causes the periodical displacement to the left of a ball or roller 14 and consequent operation of a contact lever 11. In the form shown the ball 14 which is located in a hole in a fixed plate causes the tilting of a disc 5 which rests on the ball 14 and' two other balls 15 and the axle of which bears on the lever 11. The balls 15 are also located in holes in the plate 12 and are arranged so as to lie outside the path of the projection 20. The hole in the plate 12 which locates the ball 14 may be elongated, Fig. 7 (not shown), so that when the projection is leaving the ball, the ball will suddenly shoot to the other end of the slot thus causing a quick action of the contacts. The plate 12 may be adjustable to vary the timing. Specification 550,549, [Group XVIII], is referred to.

Filed: 1971-11-26
Abstract: 1369239 Valves SANDERS ASSOCIATES Inc 26 Nov 1971 [27 Nov 1970] 55115/71 Heading F2V [Also in Division G3] Communication between an inlet passage 34 and an outlet chamber 55 is governed by a ball valve member 42 which is constrained to move within a bore 35a defined partly by a member 35 and partly by a plurality of stacked baffle plates 36 each of which has a series of arcuate projections formed on one face thereof (Figs. 4, 5, not shown). Arranged to be in constant engagement with the first ball 42 is a second ball member 44 which is of larger diameter than the first ball and which is constrained to move in a bore 41 whose axis is onset from that of bore 35a. The second ball 44 has applied thereto a low spring force 49 and a variable, control fluid pressure force, the latter being applied through ports 53 and 54. The two balls assume a position within their respective bores which is dependent upon the relative strengths of the inlet supply pressure tending to raise the balls and the control pressure force tending to lower the balls. In their movement between the valve fully open and fully closed positions, the balls rotate in engagement with one another and in engagement with their respective bores. The position of ball 42 relative to the baffle stack 36 determines the degree of communication between inlet 34 and outlet 55, between the projections of the baffle plates.
