Filed: 1960-04-29
Abstract: 964,971. Sanitary closets. C. F. TAYLOR (METAL WORKERS) Ltd. July 31, 1961 [April 29, 1960], No. 15239/60. Heading E1C. A toilet unit in which a pan 2 is mounted in a reservoir 1 containing a sanitary fluid which is recirculated by a pump unit 6 to flush the pan 2 has a bellows 7 and housing 9 to one or the other of which sanitary fluid can pass by way of a filter 24, the bellows 7 being operable in one direction against the influence of a spring 8 to discharge flushing fluid and returned by it in the other direction to withdraw a supply of fluid from the reservoir 1 for a subsequent flushing. The fluid is expelled through the valve 12 of the housing 9 in one form (Figs. 1 and 2) for flushing when the bellows 7 are extended by a hand-actuated plunger 11, and is drawn into the housing 9 through the valve 13 when the bellows 7 are collapsed. In another form (Fig. 4) fluid enters the bellows 7 through a valve 10 when the bellows 7 are extended by the spring 8, to be discharged when they are collapsed. The upper end of the bellows 7 has a discharge pipe 5 slidable over a prop 3a extending from the flush pipe 3. The pipe 5 is displaceable axially for flushing by a manually-operated arm 29 to collapse the bellows 7 against the influence of a spring 23 threaded thereover. The bellows 7 may be operated pneumatically. The reservoir may be fitted internally with a vertically-displaceable sleeve connected to means whereby it can be located in either one of two positions-one in which it is housed completely in the bucket in which the unit serves as a removable carry-on unit, or another in which it is extended through openings in the bucket bottom and the aircraft floor for connection to a servicing bowser. The sleeve can be set in a raised or lowered position.

Patent GB-529195-A (GB)
Title: Improvements in or relating to sheet feeding apparatus
IPC: B65H9/06
Filed: 1939-05-24
Abstract: 529,195. Feeding sheets. HARRIS-SEYBOLDPOTTER CO. May 24, 1939, No. 15414. Convention date, June 2, 1938. [Classes 100 (i) and 100 (ii)]  A front registering-device for a sheet-feeding apparatus which is especially applicable to stream feeders, is constructed, so as to do away with slow-down mechanism, by employing a large number of stops to engage the front edge of the sheet initially and then removing all but two or more of the stops so that the final registration is effected by a fewer number of stops preferably two or three. A sheet detecting device for stopping the machine in the absence of feed may be arranged near the stops. As shown applied to a machine of the kind described in Specification 506,636 in which a variable motion cylinder 11 transfers sheets to an impression cylinder 10, the sheets are fed by tapes 18 over a table 12 supported by a cross member 20 which is secured to frame members 13, 14 in a manner which permits of the angularity of the member 20 to be adjusted in a horizontal plane. The members 13, 14 are fitted with ledges 19 to which the member 20 is clamped when adjusted, the width of the member being less than the distance between the inner ends of the frames 13, 14. A bar 21 on the frame 20 projects at each end from the frames and by means of screws 23, nuts 24 and studs 25 the position of the frame can be adjusted with the aid of indicating devices. The frame is then secured laterally by screws 30, and is clamped to the ledges of the frames by clamps 23 operated by screw-mechanism. In the front of the member 29 a shaft 40 is mounted and to the shaft a number of brackets 41, Fig. 4, and 41', Fig. 5, are secured to which are connected flexible sheet stops 42, 42<SP>1</SP>. The shaft 40 is oscillated by a crank 44, link 45, and lever 46 from a cam 50 driven from the machine to which the sheets are fed, and when the highest part A of the cam 50  engages the lever 46 the stops 42, 42<SP>1</SP> all engage the front of the table 12 and the sheet is stopped by engagement with all of the stops. When the part 13 of the cam is in action the stops 42 are moved out of action but the stops 42<SP>1</SP> remain in action owing to the different angular setting of the brackets 41<SP>1</SP> from the setting of the brackets 41. Finally all the stops are moved out of action. The shaft 40 may be fitted with a bracket to which is secured a detecting device which stops the machine in case a sheet is not fed to the stops at the correct time. The table 12 is notched to permit movement of the detector if a sheet is not present, and the detector releases latch mechanism to permit operation of a device for tripping the machine. Specification 529,196 also. is referred to.

Filed: 1935-05-29
Abstract: 437,880. Brakes. SCHNELL, S., Overland, Missouri, U.S.A. May 29, 1935, No. 15661. [Class 103 (i)] A brake comprises a friction band adapted to be applied to a drum and comprising a substantially rigid portion and a flexible portion and a lever mounted at one end on a fixed pivot and connected to an intermediate point on the band and adapted to apply radial pressure to a substantial portion of the flexible portion of the band when the band is engaged with the drum. The band 3 comprises a lining carrying flange 8 and substantially one half of the band is rendered rigid by the provision of a web 9, the other half from which the web is omitted except at the end 10, being flexible. The band is expanded by a fluid. pressure cylinder 4 connected to its ends. A lever 11 of channel section is pivoted at 7 to the anchor plate and at 12 to an extension of the web 9. The band and lever are held in contact by a pin 14 on the band passing through the lever and a spring 15. The ends of the band normally rest against a stop 6 and the pivot 7 both of which are eccentric to their pivots in the anchor plate for adjustment. When the band is applied with the drum turning in the direction of the arrow, the frictional drag on the rigid part 9 acts on the lever 11 to apply pressure to the flexible part and the pull of the flexible part tends to turn the rigid part about the pivot 12 to increase the pressure on that part. A stop 19 engaging an arcuate surface on the web 9 centred at the pivot 12 limits the inward movement of the lever and enables the rigid part of the band to turn about the pivot without moving the lever when the band is initially expanded.
