Title: Hemostatic clip holder
IPC: A61B17/128
Filed: 1971-05-19
Abstract: 1345394 Hemostatic clip holder CODMAN & SHURTLEFF Inc 19 May 1971 [20 May 1970 28 April 1971] 15785/71 Heading A5R A holder for surgical clips 20 and from which they may be withdrawn in the jaws of a clip applicator (11) comprises a housing 12 having supporting members 18, 19 for the ends of the clips, and a clip forming element 10 which is mountable in the housing and has a V- or U-shaped projection 36 arranged to bear on the clips and bend them towards a V- or U-shape.  The housing 12 may be divided into a plurality of pockets by spacing members 30, each pocket being intended for a single clip. Each spacing member has a slot (26) cut in it, the slots being aligned to form a channel (27) into which is received the projection 36 of the clip forming member. The combination of the pocket shape and the natural resilience of the deformed clip keep the clip locked in position, and correctly aligned for easy removal. In order to remove a clip from the holder (see Fig. 10) the jaws (40, 41) of a clip applicator are thrust into the front of the holder, between two adjacent spacing members, thus bending the clip around the projection 36. This action completes the formation of the clip and releases it from the shoulders so that it may be withdrawn from the holder. The outer surface of the clip may carry projections at its ends to mesh with complementary projections on the jaws of the clip applicator and thus positively locate the clip within the jaws (see Figs. 15-20, not shown).

Wireless tuning-apparatus, adjustment devices for.-The shaft 7 carrying the moving elements of a variable electric condenser is mounted in bearings between end plates 4, 5 and on it is frictionallv mounted an arm 10 held between elastic washers 11, 12 and a nut. The end of the arm is pivoted at 13 to a bell-crank or other lever 14 pivoted at 15 to the plate 5, and is rotated for fine adjustment by a screw device 19 engaging a tapped hole in the plate 5 and acting on the lever 14 through the forked ends 16 thereof engaging between shoulders 17, 18 on the screw 19. A spring 21 between the arm and a cross-piece 6 urges the arm in a given direction, takes up play at the joints, and serves as the connection between the moving plates and a terminal 26, which connection may be shunted by a flexible conductor. The spring may be a strip or of the form shown. Coarse and fine adjustments are respectively effected by the knobs 9, 20, fine adjustment being obtained by suitable choice of the dimensions of the arm 10 and lever 14. The friction of the arm must be more than that of the shaft 7 in its bearings and to this end the bearings comprise journals 21, 22 in bearings 23, 24 a tapered shoulder 25 and recess limiting the movement of the journals at each end and providing exact vertical adjustment. The adjustment may be made still more precise by a double-threaded screw 19 imparting a movement to the arm of the lever 14 equal to the difference between the threads.

Title: Improvements in Hand Grenades and the like.
Inventor: BREGEON EUGENE BREGEON TEMPLE
IPC: F42C9/12
Filed: 1916-11-16
Abstract: 111,161. Temple (formerly Bregeon), E. B. Nov. 16, 1916. Projectile fuses.-Relates to percussion fuses for hand-grenades and the like, adapted by the burning of a time-fuse to become armed at a predetermined time after the discharge of the projectile, and consists in the particular combination described. A disk 4, which may be eccentrically weighted at 5, bears an annular time-fuse 6, connected to a length of fuse 7 which leads to a suitable igniting-device. The disk 4 is pressed upwardly by a spring 12 and has a rod 3 which is kept in alinement with a fixed rod 2 by means of splints 9 bound round by rings 10 of time-fuse composition. The rod 2 is fixed to a plate which may form the top of the container 1 and beneath which is mounted an annular instantaneous fuse 15, connected to a detonator by a branch 16. A spark-proof washer 13 may be provided. When the time-fuse 7 is ignited and the projectile is discharged, the disk 4 remains locked in the position shown until the rings 10 are burned away. Subsequent impact will then cause the burning fuse to be brought into contact with the instantaneous fuse 15. The Provisional Specification also describes modifications whereby the projectile may be exploded by the time-fuse if the percussion fuse fails, and also a device for putting the percussion fuse out of action so that the time fuse alone may be effective.

Title: Improvements in or relating to the measurement of electrical signals from low current high impedance sources
Inventor: BODEN PETER STANDIDGE
IPC: G01R1/28
Filed: 1961-05-05
Abstract: 1,028,631. Transistor amplifying circuits. GEORGE KENT Ltd. April 30, 1962 [May 5, 1961], No. 16489/61. Heading H3T. [Also in Division G1] In an apparatus for amplifying an input signal derived from a low current high impedance source the input signal is stored over a predetermined charging period and the stored signal is compared with a direct current feedback signal to produce a resultant error signal pulse, or alternatively the input signal and feedback signal are initially compared to produce an error signal pulse which is stored. The error signal pulse is applied to an amplifier and the output thereof is used to control the magnitude of the feedback signal in proportion to the magnitude of the input signal, the error signal pulse being applied to the amplifier over a discharge period whose duration is less than half the predetermined charging period. A signal from a high impedance source 1 such as a pH cell is connected by means of the switching relay 5 (preferably a mercury wetted contact relay) to the bucket capacitor 8. The switch blades 7 operate repeatedly to apply the voltage on the capacitor 5 to the amplifier 12, a feedback resistor 10 being included in the path. When connected to the terminals 4 the bucket capacitor 8 is charged, the charging period being about 1 second, and when connected to the terminals 6, for about ten microseconds, the capacitor is very rapidly partially discharged, so that a very much amplified peak output current relative to the input is obtained. The signal from the amplifier 12 passes via a resistance capacity network 13, 14 to a diode current gate network 15, the unidirectional output from which is applied to the integrating amplifier 22. The output from the amplifier 22 is applied to the transistor stage 25, whose emitter circuit includes the feedback resistance 10 connected by means of the feedback line 26 to one side of the power supplies 27. The E.M.F. produced in the feedback resistor 10 by the output current of the apparatus opposes the flow of current from the bucket capacitor 8, so reducing the drain of current from the bucket capacitor and hence from the source 1. The magnitude of the smoothed direct output current of the apparatus corresponds to the input voltage applied to the bucket capacitor and this output current is used to operate an indicating, recording or controlling instrument. Two modifications specifically adapted for the measurement of voltage (Fig. 2, not shown) and current (Fig. 3, not shown) are described, and make use of a single-pole switch in place of the switching relay 5. However, the arrangement of Fig. 1 is to be preferred in that it isolates the high impedance source at all times.

Title: Improvements in and relating to gas eliminators for electric apparatus
IPC: H01F27/14
Filed: 1946-05-30
Abstract: 612,691. Actuating mechanism. BRITISH THOMSON-HOUSTON CO., Ltd. May 30, 1946, No. 16493. Convention date, June 1, 1945. [Class 135] [Also in Group XXXV] An electrical device such as a transformer is immersed in a halogenated hydrocarbon in a tank provided with a vent which opens to allow the escape of gaseous products of decomposition, an atomized substance being introduced into the escaping gas with which it combines. When an arc decomposes the liquid, which may be chlorinated benzine or chlorinated diphenyl, the pressure of the gas produced, e.g. HCl, ruptures a glass or other frangible diaphragm 6. Lever 7 and connected rod 9 move to release a latch 11 holding up a rod 12. When this drops, a substance under pressure in tank 16 is forced through a frangible diaphragm 14 and tube 17 and is sprayed at 18 into the escaping gas. This substance, which may be a solution of sodium hydroxide, sodium carbonate, potassium carbonate or potassium hydroxide, and may have anti-freeze properties, absorbs the toxic HCl and prevents danger to health in an enclosed space such as a locomotive or ship. Also a finely-divided powder may be used as absorbent. Modifications are described in which the diaphragm 14 is replaced by a valve, Fig. 2 (not shown), diaphragm 6 is broken by the impact of a spring- urged lever released by a bellows operated by the pressure in the transformer tank, Fig. 3 (not shown), and the absorbent material is released by a valve opened electrically when a pressure-operated contactor is closed, Fig. 4 (not shown). Specification 568,055 is referred to.

Abstract: 614,944. Wrapping-machines. SCHWEIZ INDUSTRIE-GES. May 31, 1946. No. 16527. Convention date, Dec. 28, 1945. [Class 94 (i)] In a method of applying wrappers to objects in which, during the working stroke, at least two gripping devices carry the object and the wrapper through a folding compartment whereby the wrapper is applied to at least two side walls of the object, the object and the wrapper being then brought under the action of a series of folding devices adapted to carry out further folding processes, on completion of the working stroke the folding and gripping devices return to the starting position, at least one of the gripping devices in so doing being adapted to pass outside the folding compartment. In the form shown the object G and wrapper H are moved upwards between the feeding slide 1 and dolly 2 (on a carrier 12 moved on the guide 14 by a draw-rod 13) through a folding box 3 of known construction, the wrapper being then folded from the top downwards. On reaching the top the stop 6 moves down and the pusher 4 presses the object against it. The feeding slider then moves down to the starting position and side folders 7 and 8 and the under-folder 5 press forward in sequence to form the wrapper into flaps under the object and support it so that the stop 6 is moved upwardly and the pusher 4 finally pushes the object over the static folder 10 to complete the wrapping. The dolly 2 is then rotated by known means and led downwards behind the edge 11 of the folder 5 to the position 2<111>, and then to the position 21. In a modified form the dolly is moved out away from its working position by translation instead of by rotation. In a further modification the dolly is in one piece and is non-rotatably slidable on a guide rotatable about its axis fixed to the frame of the apparatus, the dolly guide being controlled to rotate so that the dolly is moved out of the working position. The dolly may traverse a curved path during its feeding stroke.

Abstract: 1,076,363. Selective printing. ELECTRONIC ASSOCIATES Inc. April 20, 1965 [April 17, 1964], No. 16615/65. Heading B6F. A high-speed output printer comprises a type-wheel 10 which is stopped in selected position by an electromatically operated pawl 41 but the drive means comprising a stallable electric motor 32, worm 33, and worm wheel 28 is connected to the type-wheel 10 through a resilient connection shown as a helical spring 30 so as to permit continued motion of the drive and store up potential energy when the type wheel is suddenly stopped. When the next character is to be selected the type-wheel starts with the extra force stored in the spring 30. Reverse rotation is prevented by a spring detent 50 engaging teeth 52. Type-wheel construction.-The type-wheel 10 has an upper ring 10d, Fig. 1A (not shown), a middle ring 10b and a lower section 10c notched to receive the lower squared portion of the print lugs 11 to prevent their rotation. Electrical type-action.-When the type is in selected position an electromagnet 13 is operated to move the type-lug to effect impression. A second electromagnet 14 may be operated when it is required to print the character in a position 90 degrees to that of that associated with electromagnet 13. Input arrangement; type selection.-A sixbit input from source 56, Fig. 1B (not shown), is received in detector 55 which produces an output signal in the form of a high-voltage pulse having a steep leading edge when an input code exactly agrees with a local signal derived from six brushes sensing a code wheel 25. Upon coincidence, output from a terminal 55a is applied to a solenoid 40 operating the stopping pawl 41, Fig. 1. The code wheel 25 coacts with two sets of brushes 35, 35a which are switched into circuit according to which of the electromagnets 13, 14 are to be used. This is determined by a switch 99 and flip-flop network 93. Ink-ribbon mechanism.-The ink-ribbon is fed downwardly from a supply spool, then horizontally below the two printing solenoids 13, 14, and then upwardly over idler roller 100, to a friction roller 101 and pressure roller 103 before being taken up on a spool 105. This spool is driven by a friction drive from a motor and takes up the ribbon which is released by an escapement device comprising a ratchet 107 and an electromagnetically operated escapement arm 109. The arm is actuated each time a print magnet 13 or 14 is energized.

Abstract: 562,589. Hydraulic accumulators. PRATT, J. H., and GIRLING, A. H. G. Nov. 24, 1942, No. 16624. [Class 69 (ii)] [Also in Groups XXVIII and XXXIV] An hydraulic servomechanism suitable for operating the brakes of a motor vehicle comprises an accumulator supplied by a pump driven by an eccentric from the driving shaft of the vehicle and means for disengaging the pump piston from the eccentric when a predetermined volume has been delivered to the accumulator. A control valve device for controlling the supply and release of liquid to and from the brakes &c. may be attached to the pump and accumulator housing. A housing 5 supported by brackets 8 from a vehicle transverse frame member 9 contains a pump piston 11 arranged to be driven inwards by an eccentric 6a on the driving shaft 6 of the road wheels, the piston being returned by a spring 13. The liquid is drawn from a reservoir 19 through a passage 5d and past double non-return valves 24 into the pump cylinder 11a and is forced past a non-return valve 26 and through passage 5e into an accumulator chamber 16, thus forcing outwards the piston 15 against the pressure of springs 20, 21 bearing on a seat 22. The piston 15 is secured to a rod 17 upon which the piston 11 is slidable and the piston 11 has a greater area than that of the piston 15. As the pistons move to the right a rubber buffer between the piston 11 and the rod 17 is thus compressed. When the accumulator is full, the pressure in the chamber 11a falls by leakage past the piston 11 permitting the buffer to move the piston away from the eccentric 6a. Control of the brakes is effected by valves 28a, 28b contained in a casing secured to the housing 5. The chamber 27 is connected to the pipelines and is normally connected to the reservoir 19 through passages 29b in a piston 29 and a passage 5g. Operation of a lever 31 by the pedal moves the piston so as first to seat the exhaust valve 28b and then to lift the valve 28a to permit the supply of liquid from the accumulator to the chamber 27 and the pipelines through passages 5e, 25a. The brake pressure reacts through the piston 29 on to the pedal. A braking pressure in excess of that produced by the accumulator may, if desired, be applied by the pressure applied to the piston 29, this being rendered possible since outward movement of the accumulator piston 15 is limited by a stop 34.
