Title: Motor and pump for gaseous and fluid driving media and the like
IPC: F04C18/356
Filed: 1932-04-25
Abstract: 405,238. Rotary engines. GOMANN, R., 101, Vieringhausen, MELCHIOR, E., 19, Alleestrasse, both in Remscheid, and BILSTEIN, H., 38, Hochstrasse, Ronsdorf, Wuppertal, both in Germany. April 25, 1932, No. 11891. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 9, 1933]. [Class 110 (ii).] A rotary engine or pump has one or more automatically operated outwardly sliding abutments d and two or more vanes c<1> on a rotor a. Two cams o, q, on the shaft co-operate with projections n, m, on a rocking lever l to control the movements of the abutment d through links k, h, g. Driving fluid such as water, oil, steam, petrol, gas, or air, is admitted to the working chamber at z and exhausted at s. Fig. 4 shows one form of engine in which an abutment u just past the exhaust port causes a vacuum to be formed in the working chamber between the abutment u and the piston vane c<2>, which produces suction of working fluid from z when the vane c<2> passes the inlet. In Fig. 5 a pump 1 and a gear motor 2 act as a reduction gear. A pressure reservoir 6 is situated between the pump and the motor to overcome irregularities of flow of the fluid. The pump is coupled to the motor whose speed of rotation is to be reduced. To increase the speed of the motor, the engine 2 acts as a pump for the engine 1. Fig. 6 illustrates a variable speed gear in which a pump 15 sucks fluid from a container 32 and supplies one, two or three motors 16 on the same shaft, through pipes 24, 25, 26, by way of a multi-ported valve 19. As illustrated in the figure all three motors are being fed by the pump 15 through the pipes 24 ... 26. The motors exhaust the fluid through pipes 27 ... 29 and pipe 31 to the container 32. To secure an intermediate speed of the motor shaft, the passage 23 connects pipes 24 and 27 to cut out one motor 16. For top speed the pipes 24, 25, are connected to pipes 27, 28, and the driving fluid passes only through one motor 16. With the passage 23 placed horizontally, the driving fluid passes straight through the valve back to the container 32. If the valve 20 is turned through further angles, three reverse speeds are secured. In a modification of Fig. 4 two abutments d are placed 180‹ apart and the inlet and outlet ports are duplicated to secure a double-acting effect. In the case of steam engines several machines of varying sizes may act as a compound expansion engine. The mechanism for operating the abutments may be varied.

Class 87 (2) An open-turn winding 2 of thermoplastic strip is applied to an electric conductor 1 (a single wire or stranded wires) by feeding the heatsoftened strip continuously from a reel 18 to a helical cavity in a rotating mould 13 through which the wire passes. The wire is drawn from a supply 4 through a hollow spindle 14 and mould 13 by a capstan 3 and take-up drum 10. The mould is attached to the spindle 14, which is mounted in bearings 15 and is rotated by a chain drive 16 from a shaft 11 that drives the capstan and take-up drum. The reel 18 is rotatably mounted on the spindle 14 within a fixed casing 28 into which hot air or steam is fed through pipe 27 to soften the strip (polyethylene). The strip is led to the mould over a pulley 20 on an arm 24 fixed to an arm 25 on the spindle. A friction brake 26 prevents over-running of the reel. The strip passes under a plate 21, which is fixed to the mould, into an open helical slot 22 formed in the mould wall. A waterspray 29 cools the wound strip, which unscrews itself out of the exit end of the mould. In modifications (1) (Figs. 5 and 6, not shown) the plate 21 is replaced by a roller mounted on the mould (2) Fig. 7 (not shown). The mould is cooled by fluid passing through helical channels therein, whereby the strip is not wetted. (3) (Fig. 8). The mould consists of a single helical #-section 47 (4) (Figs. 9 and 10). The mould consists of a helical bar 50 having pairs of freely rotatable rollers 52 projecting radially inwards, the strip being guided between the rollers. In general:- The moulds described above form a single-start thread, but may be such as to form a two or more start thread. The strip supply reel may be eccentric to and rotate bodily around the wire. The friction brake may be adjustable automatically by means responsive to the tension in the strip. The mould may be cooled by an air blast, or the air blast may follow the water cooling to dry the helix. The wire may have insulating and/ or conducting material lapped thereon before the helix is applied.

Abstract: 552,097. Fabrics comprising synthetic linear polyamide fibres. DU PONT DE NEMOURS & CO., E. I. Sept. 19, 1941, No. 12113. Convention date, Feb. 13. [Class 2 (ii)] The resilience and other properties of a fabric, e.g. of the woven, knit or felt type, comprising synthetic linear polyamide fibres, e.g. polyhexamethylene adipamide, are improved by heating the fabric at a temperature closely approaching the fusion temperature of the fibres by passing the fabric over a heated surface or between two heated surfaces under pressure. A heated metal surface and a fabric covered roller may be used or two rollers electrically heated and thermostatically controlled. The temperature may be between 5 and 25 C. below the fusion point and the fabric may be uniformly moist with water and/ or other swellingagent. A short time only is necessary for the treatment. The polyamides are obtainable, e.g. by self-polymerization of monoaminomonocarboxylic acids or by reacting diamines with dibasic carboxylic acids in substantially equimolecular amounts. Instead of using amino acids, diamines or dibasic carboxylic acids the equivalent amide-forming derivatives thereof. may be used. The amino acid derivatives include the ester, amide, lactam, N-formyl derivatives, and when water is present, the nitrile. The diamine derivatives include the carbamates and the N-formyl and N: N<SP>1</SP>- diformyl derivatives. The dibasic carboxylic acid derivatives include the diester, monoester, anhydride, amide, acid halide, and, when water is present, the mono- and dinitriles.
