Patent GB-164638-A (GB)
Abstract: 164,638. Natter, O. Aug. 18, 1920. Cam-actuated pumps; stroke, varying; reciprocating-cylinder pumps; delivery pipes; valves, arrangement of.-Consists in lubricating pumps which supply the same or different oils in varying quantity to various parts of a machine, and comprises a cylinder which has alternate reciprocating and rotary movements. Fig. 1 shows a pump with two cylinders arranged in tandem with the driving-mechanism between. The casing is of aluminium with cast iron liners 2. The cylinders 3 are in the form of sleeves connected by pins 5 to a central rod 4 and slide overplungers 12 which are capable of a variable axial movement to vary the quantity of liquid drawn into the cylinder. The cylinders are reciprocated by a cam 8 on a transverse shaft 6 which also carries a tappet-wheel 7 gearing with a tappetwheel 9 mounted on one cylinder so as to rotate it, but allow it to move axially. Each plunger 12 has a collar 15 with a pin 23 sliding in a hole in the cylinder so that the plunger rotates with the cylinder. Each plunger has also an arm 13 engaging during each suction stroke with one of a number of adjustable stops 14, which limit the plunger's inward movement. while its outward movement is limited by the collar 15. A pistonring 16 in each plunger causes it to move with the cylinder, this inward movement being assisted by the suction. In the casing and liners there are four suction passages 18 and four delivery passages 19 for each cylinder spaced equidistantly round the casing, and each piston has one port 27 which registers with each of the ports 18, 19 in turn. The delivery passages 19 lead to pipes 20 having spherical ends so that the pipes can be secured at any desired inclination by screws 22 which have passages 21 for the liquid. At the commencement of a suction stroke, the plunger 12 moves inwards with its cylinder 3 until the arm 13 engages a stop 14. The cylinder continues its movement and liquid is drawn in through the passage 18 and port 27, as shown at the upper part of Fig. 1. At the end of the suction stroke a dwell on the cam 8 allows the cylinder to remain at rest, longitudinally, while the wheel 7 rotates it to bring the port 27 into register with a delivery passage 19. The rotation then ceases and the delivery stroke is effected.

Filed: 1945-06-28
Abstract: A cured dimethyl silicone elastomer as described in Specifications 592,018 and 594,481 is converted into a composition capable of being moulded or extruded by mechanically disintegrating it and intimately mixing with a dimethyldihalogenosilane.  Preferably the mixing is performed while working the material on mixing rolls or on another suitable mixing device.  A little fresh dimethyl silicone gum may be added to the mix.  The amount of dimethyldihalogenosilane added should not exceed 2 per cent by weight of the silicone content of the cured elastomer.  A small amount of benzoyl peroxide may also be added to the mix during milling.  In the example, a dimethyl silicone elastomer prepared according to Specification 594,481 and containing titanium dioxide as filler was cured with benzoyl peroxide and the cured material was milled on mixing rolls until torn apart.  A toluene solution of dimethyldichlorosilane was added and milling continued.  The product became sticky.  A toluene solution of benzoyl peroxide was then added, and the product moulded to sheet form.
