Abstract: 1,228,033. Preparation of organic hydroperoxides and their use in the epoxidation of olefines. ATLANTIC RICHFIELD CO. 19 June, 1968 [21 Sept., 1967], No. 29313/68. Heading C2C. The invention relates to a method for the production of organic hydroperoxide in which an organic compound having a tertiary aliphatic carbon atom with a hydrogen atom attached thereto having the formula R 3 CH wherein each R is alkyl, aryl, aralkyl, alkaryl, alicyclic or heterocyclic e.g. isobutane or cumene is oxidized in a non-catalytic liquid phase which a free oxygen containing gas and a reaction mixture containing an aqueous solution of an alkaline metal pyrophosphate e.g. sodium pyrophosphate. The invention also relates to the use of the hydroperoxide produced in the epoxidation of an olefin e.g. propylene which is catalysed by a molybdenum-containing catalyst. In an example isobutane and molecular oxygen are reacted under pressure and a solution of sodium pyrophosphate decahydrate injected into the reactor which increase the selectivity i.e. tertiary butyl hydroperoxide content of oxidation products to 55 weight per cent.

Abstract: 1,228,821. Flame igniters. SIMMS GROUP RESEARCH & DEVELOPMENT Ltd. Feb. 7, 1969 [Feb.14, 1968], No.7251/68. Heading F1B. A subsidiary cylinder 15 is connected with the main cylinder 12 of an internal-combustion engine by a passage controlled by a valve 17. The valve controls the passage so that part of the charge in the main cylinder passes into the subsidiary cylinder during the compression stroke of the main piston. A subsidiary piston 14 in the subsidiary cylinder increases the compression of the part of the charge in the subsidiary cylinder and additional fuel is supplied to the subsidiary cylinder. As shown a small pilot charge of fuel is injected through the inlet 9. This causes ignition to begin in the cylinder 15. At this point the valve 16 opens. Flame enters the main cylinder 11 and ignites the charge which is there present.

Abstract: 1,231,951. Windscreen washer pump. TRICO PRODUCTS CORP. June 2, 1969 [May 31, 1968], No.27841/69. Heading F1A. A windscreen washer pump comprises a housing 26 having a chamber 36, divided into first and second compartments 36a and 36b by a diaphragm 32 operable by means of a reciprocable cam follower 58 engaged by eccentric 68 keyed to a drive-shaft 24, means being provided for selectively positioning the diaphragm 32 in continuous engagement with the cam follower 58 or free from engagement therewith. The diaphragm 32 is clamped between the housing 26 and a closure cap 27, and the peripheral portions of the diaphragm form non-return flap valves communicating inlet and outlet ports with the pumping compartment 36b. The cam-follower 58 is reciprocated on rotation of the eccentric 68 by means of a spring retainer 60 and a spring 64, the pre-load on the spring 64 being such that in the event of an excess pressure in the compartment 36b, the spring 64 will compress to allow reciprocation of the retainer 60 within the follower 58. To operate the pump, the compartment 36a is evacuated by connecting it, via port 38 and a manually operated control, to a vacuum source. This draws the diaphragm 32 into continuous contact with the follower 58. To stop pumping, the port 38 is connected to an atmospheric vent. The diaphragm may be replaced by a reciprocable piston.

Abstract: 1314181 Making filter elements D A G MARSHALL 19 Feb 1970 [14 Jan 1969] 3091/69 Headings B1D and BIT [Also in Division B5] An air filter is made by forming on one surface of a sheet of porous material a grid or mesh or discrete separated strips of molten thermoplastic material and pressing the sheet whilst the thermoplastic material is still molten against a further air filtering element. The thermoplastic materials act to bond the sheet and element together and, when cooled and solidified forms a reinforcing grid. The sheet may be of air filtering paper, glass fibre paper, synthetic open celled plastics foam, for example foamed polyurethane, random-fibre mat or mono-filament screen. The thermoplastic material may be polyethylene and, if desired, internal reinforcing lengths of string, cord, or wire or nylon may be incorporated in the material to give added strength. In one embodiment, a porous sheet, is passed in front of a first multi-orificed extruder to form lines on its surface in one direction, twisted through an angle, preferably 90, and then passed in front of another multi-orificed extruder to form intersecting lines in another direction. Whilst the grid thus formed is still molten a further filtering element is pressed against it, and the extruded material allowed to cool. If desired a single extruder may be used and the sheet passed twice in front of it. Also relative movement between the sheet and the extruder can be obtained by moving the extruder whilst keeping the sheet fixed or allowing it to move. In one embodiment, a laminated filter element, the components of which are bonded by molten grids 40, 42, includes outer layers of demembraned polyurethene foam 36, 38 and an inner layer 34 of a pleated laminate comprising a sheet of phenolic resin impregnated glass cloth bonded to a filtering layer of, for example, glass fibre paper or demembraned foamed plastics material.
