Title: Process and apparatus for producing asphalt paving material
IPC: E01C19/10
Filed: 1973-02-14
Abstract: 1409770 Mixing apparatus H N SHEARER 14 Feb 1973 [3 Nov 1972] 7253/73 Heading B1C [Also in Division F4] In a method and apparatus for making a bitumen/aggregate mix, wet aggregate is metered by a continuous weight control device 12 to an endless belt 14 where it is sprayed with water if necessary at 22 to bring it to a predetermined moisture content, sprayed with heated liquefied bitumen at 30, and charged to one end of a rotatable mixing/ drying drum 32. Air is drawn through the drum by an exhaust fan 50 and heated by a burner 40 at the inlet end of the drum. The latter has stationary end covers 36, 38 and the burner 40 is spaced from the point of entry of the mix to prevent flame contact with the bitumen; in a modification (Fig. 2, not shown) the flame is surrounded by a tube (41) which extends into the drum to a point where there is no visible flame, and the entry shoot for the mix is bifurcated to deliver each side of the tube. The burner may be controlled by a temperature sensor in the mix on the exhaust gas and the aggregate, bitumen and water feeds may be interlocked to maintain a constant ratio. The drum 32 has quick conveying spiral flights at the charging end, followed by segmented, stepped flights and then by straight flights 32a. Preferred dimensions, flow rates and other parameters are recited. The process reduces the discharge of fines into the atmosphere and protects the bitumen against premature ageing or hardening.

Title: Apparatus for moulding explosive cartridges
IPC: B29C43/22
Filed: 1956-03-08
Abstract: 790,273. Moulding explosive cartridges in roller machines. POUDRERIES REUNIES DE BELGIQUE SOC. ANON. March 8, 1956 [March 8, 1955], No. 7339/56. Class 87(2). Grooved moulding rollers 3, 4 are covered with resilient rubber sleeves 5 and rotate in the direction of the arrows. Loose explosive material 2 falls from a hopper 1 between the rollers where it is compressed, the pressure forcing the rubber sleeves into the grooves. As the rollers move apart the tension in the sleeves ejects the moulded articles (cartridges), which, connected by fins, fall along a guide 6 having a sharp cutting edge. As soon as the lowermost cartridge is gripped by cutting discs 7, 7a, which cut it to the proper length, its fin is forced against the cutting edge and it is severed from the string emerging from the rolls. The cartridges fall between the rolls R which carry the discs, onto a conveyer. The longitudinal seam remaining on the cartridges may be removed by rotating the rolls R in the same direction but at different speeds. The rollers 3, 4 may be made of aluminium or synthetic material.

Abstract: 115,320. Shakeshaft, C. E. M., and Clarkson, T. J. R. June 12, 1917. Gas supplying by meter; money boxes or receivers. - The adjustable pricechange plate A, provided with the usual coin slot and graduated perforations and serving to determine the initial position of the coin carrier, is secured within the rebated edge of the fixed drum casing 2 by means of a locking member 14, which is adapted to overlap the front of the drum casing and perforated plate, and to engage in one of the perforations, and to be locked to the side oi the drum casing. The locking-member 14 is provided with a projection 15, which is inserted into the required perforation, and with a finger 16 and notch 17 for indicating the corresponding graduation. The locking-member is secured between fillets 22 on a boss 20, projecting from the side of the drum, by a bolt 18, which screws into the boss and is provided with a collar 21 engaging against a rebated portion 23 of the member.

Filed: 1940-05-09
Abstract: 541,084. Spray carburetters. BENDIX AVIATION CORPORATION. May 9, 1940, No. 8385. Convention date, May 11, 1939. [Class 7 (iii)] An accelerating-pump comprises a diaphragm 110, Fig. 4, connected at the left-hand side by a passage 124 with the induction pipe 10, so that when the throttle is rapidly opened, the diaphragm 110 is moved to the right by a spring 126 thereby forcing fuel from the right-hand side 106 of the diaphragm past a valve 152 and through jet orifices 170. The valve 152 is connected to another diaphragm 140 separating two chambers 102, 104 connected together by a restricted passage 186 and supplied with fuel from a passage 182, the fuel also passing through openings 132, 134 to the right-hand side of diaphragm 110. When this diaphragm is moved to the right upon accelerating, the diaphragm 140 is also moved to the right, owing to the restruction 186, thereby opening the valve 152 until the fuel pressure has again equalized through the restriction 186. In a modified form of accelerating-pump, fuel is supplied from the passage 182 to the chamber 104, and the chambers 102 and 106 are connected together by a restricted passage, and the chambers 104 and 106 by a passage with a non-return valve. The main jets are formed by orifices 92 in a cross piece 30, the fuel being supplied to a passage 88 in the cross piece past a valve connected to a diaphragm so as to be opened by the fuel pressure. The accelerating-pump and the main jets are supplied with fuel by a pipe 32, Fig. 1, from a chamber 39 above a diaphragm 44, which controls a valve 52 admitting fuel from a pump 55 to a chamber 40 below the diaphragm, the stem 45 of the valve being connected to other diaphragms 41, 42, 43 forming chambers 37 and 38 connected respectively to an annular chamber 25 formed around a Venturi 22 in the air intake, and another annular chamber 23 communicating with the throat of a second Venturi 20. The space above the diaphragm 41 is connected to the space 40 by a passage through the stem 45. The space 25 is connected with the air inlet 18 by tubes 26, so that the difference in pressures produced in the chambers 38 and 37 is proportional to the square of the velocity of air flow, while the pressures at opposite sides of the diaphragm 44 are proportional to the square of the velocity of fuel flow, owing to a metering restriction 61 in the connecting-passage 60. In a modification, the accelerating-pump may be connected to the chamber 40, or to the pipe 57 leading from the pump 55, instead of to the chamber 39. The diaphragms may be made of silk impregnated with neoprene or other artificial rubber compound.

Title: Improvements in or relating to processes for the production of thomas steel
Inventor: KOSMIDER HANS
IPC: C21C5/30
Filed: 1952-04-02
Abstract: Crude Thomas iron having more than 1 per cent. of phosphorus and more than 3 per cent. of carbon is blown with an oxygen-enriched blast containing 30-55 per cent. oxygen by volume under a soda, soda-lime, or lime slag and at a time corresponding to 40-70 per cent. of the foreblow from the beginning of the foreblow there is effected an additional supply of oxygen.  The additional supply of oxygen may be obtained from ore, water vapour, or gaseous oxygen; in the latter case cooling additions are necessary to prevent rise in temperature of the bath.  The amount of oxygen added will depend on the nitrogen required in the final bath but a usual amount is 12-13 cubic metres per metric ton of metal.  A final addition of solid pig iron, hot or cold, or liquid pig iron may be made to deoxidize the bath.

Title: Improvements in or relating to hydraulic brakes
IPC: F16D57/04
Filed: 1945-04-05
Abstract: 589,790. Brakes. AKT.-GES. BROWN, BOVERI, & CIE. April 5, 1945, No. 8454. Convention date, April 14, 1944. [Class 103 (i)] In a fluid friction brake, the blades 4 of the impeller carried by the shaft 1 are enclosed to a regulable extent by a slidable ring 5, so that when the impeller is completely enclosed, the braking effect is reduced to a minimum. The inner edges 17 of the blades 4 lie on an imaginary cylinder so that secondary circulation is minimized. A double-sided impeller with two rings 5 is shown, the rings being controlled by a number of screwed rods 6 passing through hollow blades 7 on the casing 3. The blades may be covered on one side by a plate 16 which forms a seal joint 8 to prevent direct connection between the pressure and suction sides. Cooling- water may be supplied to the seals. In a modification, Fig. 3, the rings 5 are controlled by hydraulic pressure admitted to the space 11 through a passage 10, and an axially adjustable pin 12 which acts as a valve on the end of a passage 13 in the ring and leading to the suction side of the circulation system. The pressure generated by the impeller tends to move the ring 5 against the pin 12, and the pressure admitted through the passage 10 tends to move the ring 5 to open the relief passage 13. Regulation of the brake is thus affected by altering the position of the pin 12, and the water admitted at 10 passing the seal 18 cools the brake.
