Title: Improvements relating to pumps
IPC: F02M59/14
Filed: 1934-12-14
Abstract: 441,798. Reciprocating pumps. RAWLINGS, G. W., Willow Meer, Park Hill, Kenilworth, Warwickshire. Dec. 14, 1934, Nos. 35895 /34 and 13169 /35. [Class 102 (i)] A curved metal tube 4 of elliptical cross-section is enlarged at one end 4a and secured to a housing 11 by a screw 10. The other end is attached to a lever 5 reciprocated by a cam 9. The tube 4, chamber 11b and connecting passages are filled with a liquid or plastic substance which is free from air and of a high bulk modulus, e.g. mercury. The chamber 11b has one wall formed by a diaphragm 19. Reciprocation of the diaphragm draws liquid through the valve 14 and discharges it through the valve 17. The delivery is terminated abruptly by the diaphragm lying flat across the end of the port 13a. The volume of the pumping space is greater than the maximum quantity capable of being pumped each stroke. The suction is assisted by the shape of the diaphragm which is dished, or the lower end of the block 13 may be dished. The first Provisional Specification describes an arrangement in which the diaphragm is not employed.

Title: Improvements in or relating to non-return or exhalation valves
Inventor: HISCOCK PETER GORDON
IPC: A62B18/10
Filed: 1955-12-16
Abstract: 824,264. Respiratory appliances. NORMALAIR Ltd. Dec. 6, 1956 [Dec. 16, 1955], No. 36094/55. Class 81 (2). [Also in Group XXIX] An exhalation valve comprises an inflatable valve member 14 housed in a valve chamber 12, the valve member being inflatable by oxygen supplied through a duct 21 from a regulator controlling the pressure of oxygen to a pilot's breathing- mask, the inflation of valve member 14 resulting in the closing of outlet ports 13 in the valve chamber to prevent the passage of air into the valve chamber during inhalation. Upon exhalation through the orifice 27 the increase in pressure in the valve chamber causes the valve member 14 to roll back upon itself and partially collapse to uncover the ports 12 to allow the exhaled air to escape to atmosphere. A flexible non-return valve 26 closes the orifice 27 on inhalation to prevent any tendency for the valve member 14 to collapse during a deep inhalation.

Title: Station for automatic nonsynchronous multistation assembly machine
IPC: B23Q7/14
Filed: 1971-08-02
Abstract: 1362387 Stopping articles during transit on conveyers BENDIX CORP 2 Aug 1971 [3 Aug 1970] 36284/71 Heading B8A [Also in Division F2] A conveyer 16, 18, carries workpieces 34 on pallets 32 past a series of work stations 12, each of which includes operating means for performing operations on the workpiece, at least one of the operating means including cam means 40 having a plurality of cam surfaces 60, 62, 64, 66, and 68, arranged relative to each other in a series extending transversely to the path of the conveyer. The conveyer comprises roller chains 16, 18 (Fig. 2). Cam 60 drives a carriage 170 via a linkage 86 to feed bearings or seals 160 from a positioning device 118 operated by the cam 62, to a press member operated by linkage 120 driven by the cam 68. The cam 64 operates a member 114 which serves to locate the pallet 32 being dealt with at the station 12 under consideration. The cam 66 operates (via a link 92) an auxiliary clamp for the pallet. A resilient link 178 which also has a predetermined degree of lost motion in one of its directions of travel, allows for the carriage 170 to be positioned precisely between pairs of rigid stops 188, 190; and 192, 194, at respective ends of its travel. Each linkage, such as the link 90 connecting the cam 64 and the member 114 may include an overload device at its pivot 100. This comprises a housing 122 carried by a fixed frame member, a pivot member 128 rigid with the link 90, and a ball valve 124 which is urged by a spring 126 to normally close an air port 150. On overload of the arm 90, resultant camming action on the ball 124 causes venting of air from a pressure source 146. Consequent pressure drop acts on a pressure switch 152 to apply a brake 46 and clutch 45 in the drive to the cam drum 40.

Patent GB-1119511-A (GB)
Title: Elimination of the preferred orientation distortions of an x-ray diffraction pattern
Inventor: WILCHINSKY ZIGMOND WALTER
IPC: G01N23/207
Filed: 1965-08-24
Abstract: 1,119,511. Diffraction apparatus. ESSO RESEARCH & ENG. CO. 24 Aug., 1965 [12 Oct., 1964], No. 36333/65. Heading H5R. A method of eliminating the distortions in the diffraction pattern of a fibrous or non- fibrous material having crystallites of a preferred orientation involves rotating a sample of the material so that an axis # through the sample rotates end over end through angles # in a plane ZY normal to the plane determined by the beams incident on, and diffracted by, the sample and bisecting the angle formed by these beams. If the sample is non-fibrous, it is also spun about the # axis. If the sample is fibrous, e.g. of cylindrical symmetry, the spinning about the # axis is unnecessary and the # motion only is carried out. This is the case with all films or plane sheets whose preferred orientation is known to have such symmetry. The distortions take the form of inaccuracies in the intensities of the peaks of the diffraction patterns (Figs. 9A-9F, not shown) and are compensated for in a number of ways depending on the physical form of the material. With very small samples, the X-ray beam completely bathes the sample with radiation so that all parts of the sample are irradiated equally. A more massive sample is shaped into a cylinder or sphere and absorption of radiation is reduced by the use of an aperture diaphragm to ensure irradiation of a selected portion of the sample. A translational oscillatory motion in the plane normal to that determined by the incident and diffracted beams in a direction parallel to the bisector of these beams (the Z axis) is given to such a sample and the aperture (A), Fig. 4 (not shown), ensuring equal irradiation of every crystallite within the aperture limits. All the motions (#, # and oscillatory) have periods much shorter than that of the diffractometer recorder, whose motion, through angles 2#, is in the plane of incident and diffracted beams. With all forms of sample, a factor sin # has to be generated for combining with the intensity measurement to complete the compensation for distortions. In the described embodiment, this is carried out using a rotating filter disc 1 in the incident beam, although it may alternatively be in the diffracted beam, and synchronized with the # rotation of the sample. The disc comprises an apertured aluminium plate having aluminium and plastics absorbing plates of thicknesses varying such that the relative intensities transmitted through a sector of the disc located at angular position # approximates to sin #. The sin # factor may also be introduced by varying the X-ray source intensity. The application of the method to diffraction analysis of a sample of polypropylene, wound round a thin metal plate, is described. The record is a diffraction curve recorded on a strip chart, the distance along the chart, corresponding to angle 2#, and that vertically, to the intensity signal.

Title: Improvements in or relating to contact arrangements of electric switches
IPC: H01H13/72
Filed: 1938-12-14
Abstract: 522,540. Keyboard switches OAK MANUFACTURING CO. Dec. 14, 1938, No. 36446. Convention date, Sept. 23, 1938. [Class 38 (v)] A set of plunger operated switches suitable for tuning radio receivers comprises a frame formed of channel members 10, 11 spaced apart by end members 13 which carry end plates 15 having lugs 35, 36 which'hold in position two insulating plates 27, 127 running the whole length of the assembly. The plates 27, 127 are formed with a series of apertures 41, 43 to accommodate sets of fixed spring clip contacts 46 according to the circuit arrangements required. The movable part of each switch comprises a plunger in the form of a plate 80 slidable in members 10, 11 by means of a shank 86 and lug 96, a spring 98 serving to bias the plunger to the outermost position. The plunger 80 is formed with lugs 81 which serve to carry insulating plates 60, 160 on which the movable contacts 63, 64 are carried. Each set of movable contacts is made from a blank as shown in Fig. 7, comprising a channel member having flanges 63, 64 for engagement with the sets of fixed-clip contacts. Apertures 67 are provided which facilitate the removal of parts of the blank to divide the contact into portions as shown in Fig. 1 to suit any desired switching arrangement. The loose mounting of plates 60. 160 on plunger 80 renders the arrangement self aligning. Also the distance between the edges 63, 64 and plates 27, 127 is less than the distance between the ends of the contact jaws 46 and the plates 60, 160. This ensures that the free movement is limited solely by the rigid contact edges 63, 64. The switches are operated by pressing knobs 87, a switch being held in the operated position by a nose 105 of a sliding spring-urged locking bar 100 engaging an aperture 90 in the plunger 80. Thus any switch is released by the subsequent actuation of another switch. An end plunger 181 may also operate an " on " and " off snapaction switch.

A device for attachment to the end of a target-towing cable on aircraft whereby a target may be released and replaced by another target from the aircraft with the cable fully extended comprises a cylindrical body 32 carrying pivot pins 34 for a pair of pawls 33 having cam faces 35 which co-operate with an axially movable cam bar 36 of rectangular crosssection. A further pair of pawls 37, shown only in Fig. 3, are located just forward of the pawls 33 and the cam bar 36 is provided with recesses 56 and 57 arranged diametrically normal to one another to co-operate with the cam faces of pawls 33 and 37 respectively. The body 32 terminates in an end piece 38 and a screw 40 in the end of the cam-bar bears against the end piece to limit forward movement of the bar. . The forward end of the bar 36 is secured to a head 50 fast with a sleeve 42 capable of sliding movement within body 32 against the action of a spring 45 which, at its rear end, bears against an' anchor pin 41 mounted in the body 32. The sleeve 42 carries an end piece 44 through which the cable 18, anchored to pin 41, passes forwardly to the aircraft. The piece 44 is slotted to accommodate a further pair of pawls 53 urged outwardly by leaf springs 54. The attachment ring 25 of a target to be released and the ring 26 of a replacement target are shown. In operation, the replacement target is streamed from the aircraft so that ring 26 runs along cable 18 and strikes pawls 53 with a force which causes sleeve 42 to telescope within body 32. This causes rearward movement of cam bar 36 with the result that the cam faces of pawls 33 enter recess 56 thereby releasing ring 25 and the cam faces of pawls 37 are forced out of recess 57 as shown in Fig. 3, so that the pawls restrain ring 26, from further rearward movement. Spring 45 then returns sleeve 42 and cam bar 36 to their original positions so that pawls 37 are withdrawn and pawls 33 forced out to hold ring 26 in place of the jettisoned ring 25.
