Title: Improvements relating to surgical multiple puncture devices
Inventor: GROOM WALTER
IPC: A61B17/20
Filed: 1958-12-10
Abstract: 885,036. Surgical puncture devices. ALLEN & HANBURYS Ltd. Dec. 1, 1959 [Dec. 10, 1958], No. 39893/58. Class 81 (2). An instrument for puncturing the skin comprises a number of needles 7 removably retained in passages in a block 5 by a screw 9, the block being slidable in a tubular body 1 so that, when projected, the needles can penetrate the skin of the patient. Movement of the block 5 is limited by an inwardly directed flange 2 on the bottom of the body 1 and the length of the stroke, and thus the depth of penetration, is determined by rotating a sleeve 12 which has studs 11, 17 engaging the block and a helical groove in the body. A presser foot and guide 14 is attached to the outer sleeve by extension pieces 16. When the instrument is being used the block 5, carrying the needles, is pressed down, relative to the body, by a plunger 22 which is thrust downwards by a spring 21, this being first compressed by manual pressure and then released by automatic disengagement of a retaining catch.

Title: Sterilizable and sterilized hypodermic syringe assembly
IPC: A61M5/315
Filed: 1958-03-14
Abstract: 847,914. Hypodermic syringes. WILBURN, E. H. March 14, 1958, No. 39985/59. Divided out of 847,913. Class 81(2). A hypodermic syringe comprises a barrel 50 with an open rear end and a front outlet passage, a remarkable protective cap 69, which is mounted on the front of the barrel and is constructed so that in one position it provides flow passages for sterilising fluid from the exterior to the interior of the cap, and in another position closes said flow passages, and a plunger reciprocably mounted in the barrel, co-operating means on the plunger and the barrel closing the rear end of the barrel when the plunger is in forward position. The syringe barrel 50 has a bored boss 53 fitted with a hypodermic needle 55. The protective cap 69 covers the needle and fits a groove 58 between the boss and an outer annular flange 57 at the front of the barrel. Fluid passages 60 are formed in the flange and allow communication between the interior of the cap and the surrounding medium when the rear edge of the cap is pulled out of the groove but are closed when the cap is pushed firmly into the groove. Alternatively the passages may be notches cut in the rear part of the needle cap, the annular flange being omitted. A piston 19, which may be made of rubber is reciprocable in the barrel and has a stem 76 which at the rear is integral with a hood 82 and a plug 81 which closes the barrel when the plunger is pressed forward. The hood extends forwardly and is telescoped over the barrel when the plunger is projected. When the plunger is fully retracted it is located with a clearance in a flared rear part of the barrel. Notches 85 at the forward end of the hood then allow the passage of sterilising fluid between the barrel and the surrounding medium. Indicating ribs 90 on the outer wall of the hood register with markings on the barrel to give the barrel capacity for various positions of the plunger, a stop rib 88 outside the hood registering with a groove 67 at the rear end of the barrel when the plunger is retracted for sterilising. In another construction, the needle is protected against contamination by unsterilised portions of the cap as it is withdrawn, by a guide in the form of a spring strip (not shown) with a central aperture for the needle. The ends of the strip are bent against the interior of the cap. The barrel, protective cap, plunger stem and hood may be made of polyethylene.

Filed: 1962-09-23
Abstract: 969,417. Change-speed control. AUSTIN MOTOR CO. Ltd. Sept. 4, 1963 [Oct. 23, 1962], No. 40016/62. Heading F2D. Change-speed remote control mechanism for use with a motor car gear-box comprises double-acting piston type master cylinders connected by pipes to selector and ratio establishing slave units within the gear-box, the pistons in the master cylinders being operable by a gearshift lever and carrying at their ends coaxial annular valve washers serving to control flow of liquid between the pipes and a reservoir of liquid. In one form, a gear shift lever 1, Figs. 1, 2, is integral with two arms 5, 6 each engaging slots 7 in the pistons 8, 9 of two master cylinders arranged at right angles to each other. Pipes 17, 18 connect the spaces at the ends of the piston 9 with a double-acting slave unit 20 fast with a shaft 21 reciprocated thereby to engage a selector finger 23 with one of three gear strikers 24-26. Pipes 31, 32 connect the spaces at the ends of the piston 8 with a double-acting slave unit 30 connected with an arm 28 splined on the shaft 21 and operative to rotate the latter, thus sliding the selected gear striker 24, &c. to establish a ratio. Valve washers 13 loose on spigots 14 on the master pistons open axial grooves 16 along the pistons to connect the pipes 17, &c. with a reservoir 12 of liquid. When the gearshift lever 1 is pivoted in one plane, the arm 6 reciprocates the piston 9 to operate the slave unit 20 and engage the selector finger 23 with a desired striker 24, &c., the piston 8 remaining stationary. As soon as the piston 9 moves, the valve washer 13 at the operative end of the piston shuts-off the pipe 17, 18 from the reservoir 12. When ratio selection has been effected, establishment is obtained by pivoting the gearshift lever in a perpendicular plane. The piston 9 now remains stationary, but the piston 8 is slidden along its cylinder to operate the slave unit 30. In a modification, two master cylinders containing pistons 8A, 9A, Figs. 3, 4, are arranged at right angles and one below the other. Two rectangular cages 33, 34 connect the depending end 1B of a gearshift lever 1A with the pistons 8A, 9A. When the gearshift lever 1A is pivoted in one plane the cage 34 and the piston 8A move, while the cage 33 and the piston 9A remain stationary. When the gearshift lever 1A is pivoted in the perpendicular plane, the cage 34 and the piston 8A remain stationary, while the cage 33 and the piston 9A move. As before, the pistons 8A, 9A are provided with axial grooves leading to a reservoir 12A and closed by loose valve washers at their ends. Specification 735,664 is referred to.

Title: Piezoelectric transducers
IPC: B06B1/06
Filed: 1974-09-20
Abstract: 1451247 Piezoelectric transducers; ultrasonic probes ROCKWELL INTERNATIONAL CORP 20 Sept 1974 [25 Oct 1973] 41124/74 Heading H4J A piezoelectric transducer comprises a stack of spaced piezoelectric elements 11, 12, 13 which are charged simultaneously and are then discharged in sequence. The embodiments relate to an ultrasonic device for use in detecting flaws in metals and the time sequence of discharging the elements may be such that the discharge of all except the first element is timed such that the acoustic wave produced by the element is in phase with the acoustic wave arriving from an earlier pulsed adjacent element. In the discharging circuit of Figs. 2, the elements 11-13 are first slowly charged simultaneously via resistor 25. A trigger pulse is supplied to a first thyristor 26 to discharge the first element 11, and the acoustic wave so produced causes an electrical impulse to be produced by the second element 12 to cause thyristor 29 to trigger via capacitor 27 and delay 30, the delay being such that element 12 discharges at the required phase of the inpinging acoustical wave. Subsequent elements are triggered in like manner.  A further discharging circuit (Fig. 3 not shown) makes use of a plurality of coupled monostable circuits to perform the sequential triggering of the elements. In Figs. 4-6 (not shown) are illustrated sequential triggering circuits for use where a stack of elements is used without insulating material 15, 16 (Fig. 1) therebetween. In such arrangements elements are discharged in pairs. For use in the audio frequency range, each element may be subdivided into a plurality of sub-elements, the sub-elements of an element being discharged simultaneously (Fig. 7, not shown). In any of the above arrangements, the final element of the stack, e.g. element 13, may be used as a receiver. Transducer Construction.-The piezoelectric elements may comprise ¢ wavelength thick bars of material such as lead metaniobate, lead titanate zirconate or barium titanate produced by knoun ceramic methods, and polarized in a right angle mode (d 31 ). The electrodes are of vapour deposited silver and the intermediate layers 15, 16 of insulation may be of mica, which layers are glued to the elements using an epoxy EC 1469. An acoustic damper 17 is attached to the first element, which damper is formed of a metal loaded matrix material having a composition as given in table 2 (not shown). The housing 18 is filled with a plastic material or oil.
