Abstract: 380,534. Receptacles or stands for displaying and dispensing bath cubes &c. RECKITT & SONS, Ltd., Kingston Starch Works, Dansom Lane, Hull, and STABLER, W., Low Barn, Kingsgate, Bridlington, East Yorkshire. July 2, 1931, No. 19112. [Class 18.] A display receptacle or stand for bath cubes &c. comprises a sheet 12 with a series of openings or windows 2 behind which the articles, held in a series of folding receptacles 1, are displayed, the sheet being hinged centrally to a support 13 which can be folded back on to the front of the sheet 12 when the receptacle or stand is collapsed. The receptacles 1 are creased at the corners so that they may be folded back against the rear face of the sheet and the creases are arranged so that half of the receptacles fold to one edge of the sheet and the other half to the opposite edge of the sheet ; the bottoms of the receptacles form struts for the support 13 in the erected condition and are cut away at the rear to allow the articles to be removed from the receptacles one at a time.

Title: Improvements in or relating to controls for fluid-pressure brakes
IPC: B23B45/12
Filed: 1931-07-02
Abstract: 390,490. Fluid-pressure brakes; valves. SERVO-FREIN DEWANDRE SOC. ANON., 68, Quai de Rome, Liege, Belgium. July 2, 1931, No. 19140. Convention date, Dec. 9, 1930. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] The inlet and outlet valves of a control device for fluid-pressure brakes are connected by a spring or other yielding member to enable both valves to remain closed during slight movement of the operating member of the valves and to permit closure of the valves if their seats are not parallel. As applied to a vacuum brake, the casing a is connected to the atmosphere at c, to the vacuum source at g, and to the brake cylinder at h. The valves k, n are connected by a spring o. If with the valves in the normal position shown, the piston d is raised by the lever e, the air inlet valve k is at first seated on the piston and after a short further movement of the piston, the spring is sufficiently tensioned to lift the valve n to connect the vacuum source to the brake cylinder to apply the brake.

Title: Improvements in process for recovering substances from a gas containing vapours of said substances
IPC: C10K1/08
Filed: 1950-08-01
Abstract: 683,322. Gas scrubbing processes. SOC. DES ETABLISSEMENTSBARBET. Aug. 1, 1950 [Aug.2, 1949], No. 19213/50. Class 55 (ii). To recover benzene coal gas &c. is passed through a turbulent body of an aqueous solution non-freezing under the working conditions and through a turbulent body of a liquid aromatic hydrocarbon having a higher boiling point than benzene, both treatments being effected below 0‹C. The aqueous solution may comprise a mineral salt such as calcium chloride or a nitrate or a solution of a glycol or glycol ether. Gas to be freed from benzol is cooled to about 0‹C. in a heat chamber A in indirect contact with treated gas, and then passes to a vessel C<SP>1</SP> in which a rotary member submerged in a dehydrating solution e.g. of concentrated calcium chloride at -20‹C. produces an emulsifying effect and a condensation of toluene, xylene, and possibly benzene. Effluent gas is similarly treated in a second vessel C<SP>2</SP> with a solvent, e.g. crude benzol from which the benzene fraction has been removed, also cooled to -20‹C. The gas then passes through a packed tower M supplied with regenerated solvent to heat exchanger A. The dehydrating solution from vessel C' is regenerated by indirect heat exchange with regenerated solution, and concentration by evaporation in a vessel E after decanting in a vessel D a top layer having a high content of benzene homologues. The solvent from vessel C<SP>2</SP> when containing 25-30 per cent of benzene is warmed in a heat exchange H and distilled in a column I, the debenzolized liquid being pumped to a tank L and returned to the emulsifier through heat exchanger H and tower M.

Title: Method and apparatus for wrapping block-like articles
IPC: B65B11/22
Filed: 1961-05-29
Abstract: 975,759. Wrapping. K. KÍRBER. May 29, 1961 [July 7, 1960], No. 19268/61. Heading B8C. Relates to a method of wrapping block-shaped articles in which the wrapper is bent to U-form by engagement with the advancing article, the side and end flaps of the wrapper being folded in and sealed during two consecutive stacking operations. Articles 23 are pushed from a stack 4 by reciprocating pushes 3 (see Specification 972,706) against a wrapper 6 introduced by suction rollers 5. The wrapper 6 is bent to U-form as the articles advances, the small end flaps being folded in by blades 7. The package is then advanced into the first stacker 8, a plunger 10 pushing it upwards so that the side flaps are folded in by a lip 11 on the plunger 10 and the wall of the stacker 8 respectively. The stacker wall is heated to cause heat sealing as the package moves up the stacker. From the top of the stack the article is engaged by a pusher 14, side arms of which fold in the second small end flaps, and advance the package into a second stacker 12. Upward movement of a second plunger 17 causes the end flaps to be folded in by lips 18 on the plunger 17 and the walls of the stacker 12 respectively. The walls of the stacker are heated as before. The wrapper may be sealed by adhesives, the heated stackers then acting as driers.

Title: Brake master cylinder
IPC: B60T17/22
Filed: 1972-04-27
Abstract: 1357664 Master cylinders AISIN SEIKI KK 27 April 1972 [1 May 1971 15 May 1971 19 May 1971] 19642/72 Headings F2E and F2F A master cylinder for hydraulic braking system comprises a piston housing 12, a piston 14 in the housing having two working heads of equal diameter separated by an annular recess, a reservoir 11 for hydraulic fluid and a valve 26 for preventing the flow of hydraulic fluid from the annular recess to the reservoir except when the piston is in a brake inoperative rest position. In the construction shown the valve is a poppet valve which is biased by a spring 31 to close a port 25 the valve being moved to open the port when the piston is in the rest position by a projecting portion 30 of the peripheral surface of the piston. In the rest position a port 33 between the recess 24 and a chamber 19 in the housing is also open to allow communication between the chamber 19 and the recess 24, ports 34 are also provided in the piston so that fluid can flow from the recess 24 into the chamber 19 as the piston moves to its rest position; for movement in the opposite direction the ports 34 are closed by a sealing cup 15. A pressure responsive switch 36 is connected to an outlet port 37 formed in the piston housing 12 and the switch operates a warning lamp 39 when fluid pressure within the recess 24 is increased by failure of the cup 15. The reservoir is also provided with a float member 51 which closes contacts 52, 55, 56 when the fluid in the reservoir falls too low and this also operates the warning lamp 39. A tandem master cylinder is also described in which there are two pistons within the housing each associated with an individual reservoir and each operating an individual poppet valve as described above; the recess of each piston is connected to a switch to operate a warning lamp and each reservoir has a float operating contacts as described above. A construction is also described, Fig. 3, in which the reservoir is modified by connecting it to a pressure device 62; this keeps the hydraulic fluid in the reservoir constantly under pressure by means of a diaphragm piston 65, a chamber 67 in one side of the piston being connected to a vacuum source such as the inlet manifold of the vehicle and a chamber 69 on the opposite side of the piston being connected to atmosphere; thus the diaphragm piston is constantly urged to the left by the atmospheric pressure and since it is connected to a piston 71 in the reservoir the fluid in the reservoir is pressurized. The reservoir also has a port 92 to which a pressure switch 93 is connected which operates a warning lamp 39 if the pressure in the reservoir falls too low. In addition a plate 82 is connected to the diaphragm piston 65 and when the piston has moved a predetermined amount to the right owing to reduction of fluid in the reservoir caused by wear of the brake shoes the plate engages a contact 84 so that the warning lamp 39 is operated.
