Filed: 1973-04-10
Abstract: 1431092 Lubricating compositions KIMBEBLY CLARK CORP 10 April 1973 17265/73 Heading C3F [Also in Division A5] A solid lubricating composition comprises water-soluble hydroxypropyl cellulose blended with a compatible polyalkylene glycol plasticizer, and having an oleaginous lubricant dispersed throughout. Globules of the lubricant occur on the surface of the composition, some of them uniting to form a film of lubricant. The preferred plasticizers are polyethylene glycol having a molecular weight of from 200 to 1500 and polypropylene glycol having an average molecular weight of less than 750. The lubricants disclosed are glycerine, natural and synthetic fats which are liquid at room temperature, mineral oil and polypropylene glycol having an average molecular weight of at least 1000. The composition is best made by adding the lubricant to hot plasticizer and then adding the hydroxypropyl cellulose, heating some more to obtain a clear solution and then cooling. Consequently it is preferred that the lubricant and plasticizer be compatible or, at least, mutually dispersible at high temperature but incompatible at room temperature. The compositions are intended for medicinal purposes, in particular for making suppositories, and antifungal or bacteriostatic agents and antibiotics may be added. Specified materials are menthol, camphor, quaternary ammonium salts, phenylmercuric nitrate, ephedrine sulphate, benzocain, oxyquinoline benzoate, hexetidine, chloramphenicol, myraldact, aloponone, nystatin, acetarsone, nitrofurazan, benzalkonium chloride and hexachlorophene.

Abstract: 1,180,283. Reefing parachutes. BRITISH AIRCRAFT CORP., Ltd. 17 July, 1968 [18 April, 1967], No. 17820/67. Heading B7G. A parachute system used for braking aircraft or with other moving bodies comprises a line connected at one end to the lines 3 of a braking parachute and at the other end 6 to a resilient means, e.g. a spring 5, attached to the aircraft at 7; a rod 16 is pivotally connected to point 6 and to the aircraft at 17 so as to operate a valve 15 in the hydraulic circuit 14 of a positive displacement hydraulic pump 11 when point 6 is moved by the tension in the line 4. A reel 10, to which the reefing line 8 of the braking parachute is anchored, is connected to the pump 11 so that as the tension in line 4 decreases valve 15 permits flow of hydraulic fluid through the pump 11 and the reefing line 8 is payed out. When the parachute is initially deployed it is reefed, but as the aircraft slows the reefing line 8 increases the diameter of the parachute and a substantially constant retarding force is maintained until the parachute has reached its maximum diameter, the spring 5 being chosen such that the retarding force is as great as may safely be used. The pump 11 may also be used as a motor to wind in the reefing line 8 by connecting the pump between the aircraft high and low pressure hydraulic lines at 24 and 25. The reefing line may either be connected to the central point of the inner surface of the parachute canopy, or pass through loops around the mouth of the canopy, Figs. 2, 3 (not shown).

Title: Gas compressors of the reciprocating type
IPC: F01B7/20
Filed: 1945-07-13
Abstract: 591,125. Gas compressors. AUSTIN, G. F., and WOOD, D. G. July 13, 1945, No. 17898. [Class 8 (i)] In a gas compressor of the kind wherein rotary movement of a driving shaft 5 Figs. 1, 3 is resolved' by a crank or eccentric 6 into two sliding motions of a driving member 4, 4a connecting the eccentric 6 with the piston 2, 2a one of which motions being imparted to the piston and the other in transverse relation to the piston, the piston displacing motion of the driving member 4, 4a is transmitted to the piston by an intermediate member 3, 3a. At the start of each piston stroke the member 3, 3a floats in the stroke direction to provide a passage 13 for gas from an intake port 7 and passages 14, 9 to enter a major chamber A, and simultaneously to close a passage 13a to allow gas in a chamber B to be compressed prior to its delivery to a minor chamber D when passages 11a, 12a are in register. The gas after further further compression in.the minor chamber D is finally delivered when ports 10a, 8a are in register. The compressor is double acting and on the return stroke intake is by means of port 7a and passages 14a, 13a and 11a, 9a. In a modification, Fig. 11, two separate single acting pistons 2, 2a are reciprocated by a yoke 31 about the eccentric 6. The minor chambers D are in constant communication with the inlet ports 7, 14 and 7a, 14a. Passage 34 or 34a when not sealed by the inner surface of one or other of the piston heads allows gas to enter the appropriate chamber via passage 13, or 13a, the former not being shown. Outlet passages 9, 11 and 9a, 11a are duplicated so as to increase their cross sectional area and so assist delivery. Lubricant is fed through a top hole in the cylinder wall so as to impregnate a pad assembled in a counterbore of the cylinder.

Title: Improvements relating to the feeding of powdered or granular materials
Inventor: UPTON EDWARD JAMES
IPC: D01D1/06
Filed: 1950-07-19
Abstract: <PICT:0726892/IV (a)/1> <PICT:0726892/IV (a)/2> Powdered or granular fusible filament-forming material is fed into a receiving space by causing it to flow by gravity down a passage into the space, subjecting the upper surface of the material in the space to the intermittent feeling action of an oscillating member and, when the level of the surface is low, using the increased range of oscillation of the member consequent upon such lowness to effect a movement of the boundaries of the passage so as to encourage the flow of material down the passage.  As shown, the material flows through the ducts 22 (Fig. 2) into the passage 12 of rectangular cross-section and is there compacted by the longitudinally vibrating tamping rod 18, in the manner described in Specification 679,177, into a coherent rod which is carried away by the downwardly travelling endless flexible conveyer bands 10 (Fig. 1).  In the event of jamming of the material in either of the ducts 22 and consequent falling of the level of the material in the passage 12, the range of oscillation of the tamping rod 18 increases and the shoulders 34 (Fig. 2) of the rod engage the tube 32 of the yoke 25 and thus lift the yoke (to which are attached the gates 24 in the ducts 22) against the pressure of the spring 29. The jam of material in the ducts 22 is thus broken and the rate of feed of material into the passage 12 temporarily increases to make up the deficiency.  Thereafter the range of vibration of the tamping rod 18 is again restricted and the gates 24 across the ducts 22 occupy their normal position.  The rod 18 is actuated by a pneumatic vibrator unit 19.  The normal position of the gates 24 in the ducts 22 can be adjusted by adjusting the connection of the upper portion of the gates 24 to the yoke at the screws 30.
