Title: Improvements in driving mechanism for engines, compressors, pumps and other machines
IPC: F01B17/04
Filed: 1933-11-16
Abstract: 428,619. Swash-plate mechanism. WATTS, R. E., 30, Tinwell Road, Stamford, Lincolnshire. Nov. 16, 1933, No. 32008. [Class 80 (iii)] [See also Groups XXVI and XXVIII] An engine, compressor, or pump having an inclined crank-pin is constructed so that the axis of a cylinder, the axis of a crank actuated by a piston therein, and the axis of the shaft, meet in a point. In the construction shown in Fig. 1, piston extensions 7<a> carry pins 8 connected by links 9 to gudgeons 6 on a sleeve surrounding the crank-pin. The piston, alternatively, may have a forked extension directly connected to trunnions on a sleeve surrounding the crank-pin and free to move longitudinally thereon. The piston is oscillated during its reciprocation. Pairs of pistons in line may be connected to the same gudgeon pins. The piston is guided by a fork 10 with arms 10<a> engaging guides 10<b> on the extension 7<a>, which fork is mounted to oscillate in a step bearing 11. In the construction shown in Fig. 4, opposed pistons 7, and a single piston 70 of double area arranged at right angles thereto, are connected to operate the same crank. A modification is described wherein sixteen cylinders, arranged in radial, parallel groups, are connected to a single shaft. The radial pistons in the same plane actuate the same inclined crank through concentric, longitudinally-movable sleeves thereon.

Abstract: 1,120,241. Sheath-core composite filaments. KANEGAFUCHI BOSEKI K.K. 27 July, 1965, No. 32014/65. Heading B5B. A composite filament of the sheath-core type comprises a sheath of organic polymeric fibreforming material and a core of organic polymeric fibre-forming material having a modulus of elasticity greater than that of the sheath. The core has a unitary non-circular cross-sectional shape, the ratio of the second moment of a cross-section of the core referred to either of two directions intersecting at right angles to each other or any of three directions intersecting at 120 degrees to each other and passing through the centre of gravity of the cross-section of the core to the second moment of a circle having an area equal to that of the cross-section of the core being at least 0.8 and the mean of the ratios of the second moments of the core referred to the specific directions to the second moment of said circle exceeding 1.2. The shape of the cross-section of the core may be an equilateral triangle or a Y, while the cross-section of the whole filament may be circular in shape. The polymeric material constituting the sheath may be receptive to dyes. The composite filament is formed by melt extrusion. As shown in Fig. 16, the spinneret used may comprise an inner jet or nozzle 3 and an outer nozzle or extrusion orifice 4 spaced downstream from the outlet of the nozzle 3 through which is extruded the core polymer 1. Simultaneously the sheath polymer is extruded through the nozzle 4 forming the composite filament 5. Figs. 17 to 19 are examples of a plan view of the cross-section of the nozzle 3 superimposed on that of the nozzle 4. The cross-sectional shapes of the nozzles 3 and 4 and the ratio of the areas of these crosssections to one another are selected to be such as to produce composite filaments in which the relationships of the cross-sections of the sheath and core are as specified in claim 1.

Abstract: 1,272,583. Respiratory appliances. BLEASE MEDICAL EQUIPMENT Ltd. 25 June, 1969 [5 July, 1968], No. 32258/68. Heading AST. [Also in Division F2] A valve block for use in a lung ventilator has a plurality of non-return valves 48, 49, 51, 52, 53 at least two of which are coplanar. The block is formed in two mating parts with plane cooperating surfaces in which recesses to accommodate the valves are formed. Each valve comprises a seat 112 and a flexible rubber or plastics diaphragm 114 and is screwed into or is a push fit in its associated recess. The block is also provided with passages to enable it to form part of a circuit for a medical ventilating machine which is shown in Fig. 1 in the manual operating position in which a bag 357 is squeezed to force gas from a supply 363 to a face mask connected at 262, expiration being through valve 365. If valve 354 A, B, C, D is rotated through 90‹ (Fig. 2 not shown) the machine automatically ventilates, gas entering chamber 317 with valve 47 closed moving bellows 313 upwards to force gas and air past valve 53 to the face mask. When pressure in chamber 317 moves diaphragm 334 to the right against adjustable loading 335 to release pawl 339 valve 47 is opened to release the pressure and cause the bellows 313 to move downwards finishing the inflation. Expiration now takes place under the influence of the venturi tubes 342, 343 and past valve 49. The diaphragm moves to the left until the pawl 341 is released and valve 47 shuts to start the inflation. Valves 346 and 333 determine the time of pressure build up and the time of return of diaphragm 334 to the left on opening of the valve 47. Tap 320 enables the patient to have assisted ventilation or not. A rod and stop 314 limit the movement of the bellows to control the volume cycled. A second valve block construction is described and forms the subject matter of Specification 1,268,904.

Turning-gear.-In an engine-starter comprising a driving-member such as a pinion 8 mounted upon a rotary member or shaft 2 for longitudinal and rotary movement, the member 8 is arranged for independent longitudinal movement relatively to the shaft as well as the movement caused by the rotation of the shaft. In the form shown, the pinion and shaft have inter-engaging screwthreads, the threads 8<a> on the pinion being narrower than the spaces between the threads 2" on the shaft. The threads are held in contact by a light spring 11, which yields if the teeth uf the pinion clash with those of the engine member 9. The pinion can then rotate relatively to the shaft, enabling the teeth to mesh. The shaft 2 is shown as a sleeve around the armature shaft 1 of the motor A, from which it is driven through a spring 3. Specification 20811/14 is referred to.
