Title: Bookbinding apparatus
IPC: B42C9/00
Filed: 1975-04-30
Abstract: 1495766 Bookbinding XEROX CORP 30 April 1975 [30 May 1974 (2)] 17990/75 Heading B6A In apparatus for binding books with an adhesive binding strip, for instance the binding member disclosed in Specification 1,412,426, a stack 17 of sheets to be bound is held between a bi-partite clamping means, each part 27, 27a of which may be pivoted to drive the stack downwardly against the binding strip 47 and move the strip against one heated platen 14, means being provided for biasing other heated platens 12, 13 against the stack to complete the binding. The stack is initially placed manually between guides 18, 19 and rests upon a retractable plate 21. Upon clockwise, manual rotation of a knob (22), Fig. 1 (not shown), the guides 18, 19 approach one another and calipers associated therewith engage the sides of the stack and determine the position of the heated platens 12, 13. Binding strip guides 28, 29 are also moved towards each other to initial positions. The positions of the guides 18, 19 and platens 12, 13 are locked by a linear clutch Fig. 10 (not shown), when the calipers engage the stack, and are held as the knob (22) is rotated anticlockwise to set the positions of the bipartite clamp 27, 27a and final positions of the strip guides 28, 29. Several such final positions are defined by the teeth of a ratchet (92) corresponding to the several widths of binding strip which may be used for stacks of various thickness. The stack is manually moved laterally clear of the calipers. If a binding strip of appropriate width is available, a light shows. Upon actuation of a "Biro" button, clamps 27, 27a move through the guides 18, 19 to clamp the stack. A length of strip is cut and fed between strip guides 28, 29 and the clamps 27, 27a are pivoted upwardly to lift the stack clear of the plate 21 which is then retracted. The clamps are then pivoted downwards whilst platens 12, 13 are moved towards each other Fig. 5 (not shown) thereby supporting and heating the strip. Next the stack is raised, the platens 12, 13 separated and the stack lowered again, this time into contact with the biased, heated platen 14 as shown in Fig. 6. Finally, the platens 12, 13 are moved together to apply the edges of the strip 47 to the sides of the stack. Abutment means 55, 56 on the guides 28, 29 limit downward displacement of the stack in dependence upon its thickness.

Abstract: 1408291 Separating lighter and denser constituents of a mixture D V GOUGH 2 Oct 1972 [19 April 1972] 18249/72 Heading BID Apparatus for separating denser and lighter constituents from a mixture of liquids or solid and liquid, e.g. water from fuel, comprises a container with separate upper and lower outlets for the two constituents and containing a float which rises with the accumulation of heavier constituent in the lower part of the housing to shut off the upper outlet for lighter constituent to prevent loss of heavier constituent therethrough and at a preset level, by means of a proximity switch, to actuate external indication means and/or means to open the lower outlet for heavier constituent. Figure 2 shows a two-part cylindrical housing 2, 4 having a tangential inlet 8, upper axial outlet 12 for lighter constituent and normally closed lower axial outlet 36 for denser constituent. Float 14 rises with accumulating dense constituent until, at a predetermined level, magnet 24 mounted on the float triggers an electrical proximity switch 26 mounted on the housing outer wall to open solenoid valve 52 and allow denser constituent to leave. A shut-off valve 42 is mounted on a spindle 16 axially joined to the float to close outlet 12 should the accumulation of denser constituent in the housing become too great. Once valve 42 is in position in valve seat 44, it is held by suction and needs a manual re-set 56. The incoming mixture is heated by heater 66 and enters in a spiral flow around the outside of conical baffle 10. In another embodiment (Fig. 1 not shown) the proximity switch actuates a warning device only and outlet 36 is opened manually.

Abstract: 1,147,051. Lubricating. CARRIER CORP. 26 April, 1966 [26 July, 1965], No. 18279/66. Heading F2A. A lubricating system for a refrigerating machine utilizing miscible refrigerant and lubricant, comprises a first zone including a lubricant reservoir 53, a second zone including lubrication points and containing refrigerant, lubricant flow passages connecting the zones, and means segregating the zones when the machine is shut down. In Fig. 1, the second zone is a motor compressor unit 11. Lubricant is supplied from a reservoir 53 by pump 55 through lines 40, 41, 42 to bearings 33, 36, 23, 19 and returns via lines 44, chamber 21 and line 46. On shut down a switch (71, Fig. 2, not shown) in an electric circuit is opened, and after sufficient time to allow the motor compressor unit 11 to coast to a stop a relay (73) opens to cut out pump 55 and to close solenoid valve 75. Lubricant pressure then drops in line 66 and piston 63 moves to slowly close valve 52. Reduction of lubricant pressure in line 82 acts on diaphragm actuation 83 to close valve 81 in vent line 80. The zones are thus isolated by valves 75, 52, 81 and absorption of refrigerant by the lubricant is reduced. On start-up switch 71 is closed thus opening valve 75 and starting pump 55, then lubricant pressure opens valves 81, 52. A pressure responsive actuator then starts the unit. An oil heater 56 is provided in the reservoir to expel refrigerant from the lubricant.

Title: Hydraulic Ram Apparatus
Inventor: NORTON HUBERT VEARE
IPC: B30B15/16
Filed: 1968-04-22
Abstract: 1,194,623. Hydraulic presses. NORTON TOOL CO. Ltd. 14 April, 1969 [22 April, 1968], No. 18826/68. Heading B5F. [Also in Division F1] An hydraulic press ram 10 is moved rapidly towards a workpiece by oil expelled from a cylinder 53 connected by a line 18, 19 to the ram, the oil being expelled by a differential area piston 50 driven by oil supplied to a line 35 from a pump 25; when the pressure in the line 18 rises due to the ram engaging the workpiece a pressure operated changeover valve 41 opens to allow the pump supply in line 35 to flow directly to the ram through lines 44, 38, 18. The ram is controlled by a valve 29 connected to the pump through a line 27. Rotation of a lever 32 either directs the pump output to the line 33, 35, or to a line 21 connected to the ram return chamber 20, the line unpressurized being connected to exhaust. When a foot pedal 74 is depressed, links 72, 73 move the lever 32 to the position shown wherein oil flows through the line 35 to a working chamber 47 in the differential area piston 50. The area relationships of the piston 50 are such that a small volume supply from the pump 25 causes a large volume to be expelled from the cylinder space 54 to the ram. During the stroke oil is drawn into the space 55 behind the piston 50 through non- return valves 56 and this oil prevents retraction of the piston 50 when the line 18 is subsequently pressurized directly by the pump 25. The return stroke is started either by releasing the pedal 74 so that a spring 75 returns the control valve lever 32, or by arranging for the automatic collapse of the toggle links 72, 73 by a device 63 operable in response to the occurrence of a predetermined maximum ram pressure. During the return stroke oil in excess of the cylinder space 54 and also oil in the space 55 is exhausted through non-return valves 57, 61. A repeat stroke may be started automatically by arranging for a ring 14 on the ram to lift a rod 80 and thus operate the valve 29 through linkage 77, 76. In a second embodiment, Fig. 2 (not shown), the cylinder 53 is of a different construction and is protected from the full ram pressure by a valve in the line 18.
