Abstract: 1,262,955. Measuring blood pressure. WALTER BECK K.G. KONTROLL-UND FERNMESSGERATE. 28 March, 1969 [1 April, 1968], No. 16533/69. Heading A5K. A blood pressure measuring instrument comprises a cylindrical handle 1 containing an air pump 6 connected through a non-return valve 17 to an occluding cuff 25 and an air release valve 62 actuated by an operating ring 71, a pressure responsive chamber 32 in communication with cuff 25, which, through a lever system 35, 40, 42 actuates a pointer 41 moving over a scale plate 54. The handle 1 comprises a core member 3, having a recess 4, on which there is fitted a hood 5 of elastic material incorporating integrally the pump 6 and a non-return inlet valve 12 therefor. The edge 7 of the hood is sealed by a cover ring 10 against the top portion 8 of core member 3. A middle part 26 is attached by a bayonet fixing 27, 28 to the top portion 8 against a sealing ring 29 to define a chamber 19, which connects with non-return valve 17 and a bore 21 in communication with the occluding cuff 25, the chamber 19 having a central bore 30 into which the pressure responsive chamber 32 is screwed. An air escape hole 61 extends radially from bore 30 into a radial bore 60 of larger diameter containing a push rod 64. Operating ring 71 has an inwardly projecting rib 73 which provides an eccentric surface (75, Fig. 5) which acts against the curved head (74, Fig. 4) of the push rod to force a cylindrical sealing part 62 of elastic material over the end of hole 61 and into a channel (76, Fig. 3) in the end wall of bore 30. In the operation of the device, the handle 1 is gripped by the user and the bellows operated with the fingers to inflate the cuff 25. The operating ring 71 is then turned until the sealing part 62 detaches from channel 76 and allows air to bleed off slowly. The chamber 32 carries on a threaded pin 33 a ring 34 which actuates arm 36 of an angle lever 35, whose other arm 38 has a hook 39 engaging a shackle of a chain 40, the other end of which is fixed to a shaft 42 carrying pointer 41 and a spiral return spring 43. The sensistivity of the instrument may be adjusted by moving ring 34 along the axis of pin 33, and by moving the angle lever mounting pin 53, which is mounted in a bow 51 attached to a leaf spring (48, Fig. 6), whose position may be altered by turning a screw (50, Fig. 6). An alternative arrangement is shown on Fig. 7. The instrument may include a means of indicating periods of time (91, Fig. 2) and a mechanism (Fig. 2) enabling it to be wound up by turning operating ring 71, as described in Specification 1,262,954.

IPC: B21F3/04
Filed: 1972-04-11
Abstract: 1419626 Coiling springs BENNETT TOOLS Ltd 2 April 1973 [11 April 1972] 16541/72 Heading B3E A spring coiling machine comprises a rotable mandrel 14, a wire feed device 15, a head assembly 10 including a part 24 engagable with the last complete turn on the mandrel, and fluid pressure actuated means for effecting relative movement between the head assembly and the feed device thus varying the pitch of the coils. As shown, a carriage 13 slidable on guides such as 9 supports the feed device on one side of the mandrel, and a pneumatic cylinder 12 on the other side, the piston of which supports the head assembly 10. Part 24 is slidable in groove 25 in the head by handle 26, so as to permit removal of the finished spring. The pitch of the helix is controllable by the extension of the piston and cylinder, e.g. to a limit set by adjustable step 29. Thus a spring with closed ends and an open central portion may be wound by commencing winding with the piston contracted until a first mandrel revolution (or part revolution) counter effects extension of the piston, which prevails until a second counter effects contraction of the piston. The wire feed device 15 is tiltable by a handle 20 to suit the helix angle, and the handle is mountable on the device in alternative positions to define alternative wire guides used for winding coils of opposite hands.

Abstract: 574,691. Valves. FRIGIDAIRE, Ltd., and KENNINGTON, W. O. Oct. 14, 1943, No. 16860. [Class 135] A needle valve is carried on a piston by a disc which is movable transversely to the axis of the valve and through which pressure for moving the valve is transmitted. As applied to a refrigerating apparatus, the needle 9 projects through an aperture in a disc 9d which rests on the top of a spring-pressed piston 8 with the enlarged lower end of the needle resting in a recess in the piston. The valve seat 10 comprises a nipple screwed into a partition member 11 situated between the high-pressure conduit 12 and a conduit 13 leading to the evaporator. The valve responds to temperature changes in a thermostatic bulb situated at the outlet of the evaporator and pressure changes in the bulb are applied to a diaphragm 15 carrying legs 14 in contact with the top of the disc 9d. When the diaphragm rises, the legs are lifted and allow the piston to press the valve towards the closed position. In a modification, the disc 9d is secured on the valve stem between an intermediate flange and a grommet riveted on the lower end of the stem.

Abstract: 1288318 Magnetic printing apparatus PHILIPS GLOEILAMPENFABRIEKEN NV 9 April 1970 [12 April 1969] 16896/70 Heading B6C A photomagnetic copying member has a surface layer 2 which is composed of a ferromagnetic material having a magnetic property which can be changed in image form by local exposure to electromagnetic radiation (including visible light) of an intensity which does not cause heating to the Curie point. The magnetic property which is changed may be coercivity, anisotropy field or magnetic permeability, and the material may be from listed groups which include artificial garnets, spinel-structure compounds and hexagonal structure compounds. Preferably the layer 2 is supported by a rotating drum 1, and projected light images of documents 4 fall on it and produce a coercivity image. Prior to exposure the layer 2 has been magnetized by a magnet 5, and after exposure it traverses a magnetic field of different orientation, produced by a second magnet 6. The magnetic image so formed is developed by application of a toner 13, composed of iron particles enveloped in a thermoplastic material. After transfer to a receiving surface 16 the toner images are fixed by an infra red lamp 19. Excess toner on the layer 2 is removed by a magnetic brush 20. If more than one print is required from the magnetic image the drum rotates through the exposure position without an exposure, further toner is applied to the image and a second print is made. Otherwise an infra red source 23 is used to raise the layer 2 above its Curie point and erase the magnetic image, prior to the making and development of a new coercivity image.
