Abstract: 1,068,536. Suturing appliances. NAUCHNO-ISSLEDOVATEL 'SKY INSTITUTE EXPERIMENTAL 'NOI KHIRURGICHESKOIAPPARATURY I INSTRAMENTOV. April 30, 1964, No. 17947/64. Heading A5R. [Also in Division F2] A stapling device, for suturing with staples arranged in a row simultaneously, comprises a body member 1 carrying a staple anvil 2 and a slide 13 which is biassed towards the anvil by leaf springs 27, a staple magazine (43) and a staple punch 37 mounted on the slide, the punch being actuated by a lever 54 pivoted on the body member, means for adjusting the distance between the slide and the anvil according to the thickness of tissue to be sutured and clamps 7<1>, 10<1> for holding the tissue. The staple anvil 2 has a base plate 15 and transverse grooves 6, 9 located distally and proximally. An inverted U-shaped upper portion of the slide is hooked over a portion 11 of the frame. The staple magazine (43) having staple-receiving slots (47) arranged in a row transversely of the instrument is mounted on a pin 30 fixed to the slide. A sleeve on the pin may be turned by a handle (35, Figure 6, not shown) so that projections secure the magazine against movement relative to the slide. The staple punch 37, having along its lower edge projections corresponding to the slots in the magazine, has a forked upper end which is slidable on the pin. An operating lever 54 is pivoted on a pin 55 fixed to the frame 1 by a metal strip 56, its distal end extending through the slide and into a slot in the staple punch. When the instrument is not in use, a slidable plate 65, forming a safety catch, wedges the distal end of the lever against movement relative to the slide. The distance between the lower edge of the slide and the magazine from the anvil is adjusted by sliding the tapered end of a plate 24 under lower faces 23<1> of lateral projections at the upper end of the slide. In use, the tissue to be sutured is held in clamp jaws 7<1> located in the groove 6 or clamp jaws 10<1> located in the groove 9, the distance between the slide and the anvil then being adjusted to grip the tissue. After removal of the safety catch plate 65, the handle 3 and lever 54 are moved together at their proximal ends thus operating the punch to force staples into the tissue and against the anvil. The clamp jaws 7<1>, 10<1> are L-shaped and have notches or projections on their gripping faces.

Title: Improvements in electrical measuring indicating systems
Inventor: BERGEN STEPHEN ARCHBOLD
IPC: G01R17/08
Filed: 1950-07-19
Abstract: 680,853. Current and voltage measuring. EVERSHED & VIGNOLES, Ltd. July 11, 1951 [July 19, 1950], No. 18043/50. Class 37. [Also in Group XL (b)] Current to be measured e.g. from a thermo-couple 1, Fig. 1, is applied to a moving coil 7 to which is attached a second coil 9, the moving coils varying the illumination of a pair of photo-electric cells 26, 27 in a bridge circuit whose out-of-balance current controls the current in the second coil 9, so that a position of balance is reached where the larger current through coil 9 is proportional to that through coil 7 and can be used to actuate remote indicators 50 .... 52. The moving coil system 8, 9, Fig. 2, carries a slotted shutter 20 between a light source 21 and mirrors 24, 25 so that the position of the shutter determines the relative illumination of the two cells 26, 27. The out-of-balance current from the bridge 26, 27, 36, 37, Fig. 1, is applied to valve 41 to vary the current through coil 9. The controlling spring 56, Fig. 2, is anchored to one end of a bimetallic spiral 58, so that variation of ambient temperature will produce a variation in controlling torque to compensate for variation in the current through the coil 7 due to the variation in temperature of the cold junction of the thermo-couple. Variation of ambient temperature also results in variation of resistance of the two coils; this is compensated by providing a resistance 65, Fig. 1, of a high temperature coefficient of resistance (e.g. nickel) in series with coil 9 and a resistance 66 of negligible temperature coefficient (e.g. maganin) in parallel with the coil 9 and resistance 65 and preferably varied by a shunt resistance 67 also of manganin. The zero setting of the moving coils is adjusted by arm 61, Fig. 2, rotating the bimetallic spring 58.

Abstract: 930,939. Bourdon gauges. MANNING, MAXWELL & MOORE Inc. May 18, 1961 [May 19, 1960], No. 18149/61. Class 106 (2). A Bourdon-tube system for measuring a small range in the total pressure variation, comprises an input Bourdon tube S1 the tip 34 of which is constrained against deflection by a spring 38 of a material, such as the alloy " Ni-Span C " (Trade Mark), having substantially temperature - invariant elasticity modulus, until the desired pressure range is reached, whereupon deflection of the tube S1 will raise, or lower, the wheel 42, thus pivoting a semi-circularly-shaped, spring-loaded " flapper "  valve F, pivoted near the straight edge at 31, 32, to vary its distance from an air-nozzle 27 supplied by a constant pressure source through inlet 45. R is a diaphragm-valve system, and variations in the back pressure at nozzle 27 are applied, via the air-tube 28 (this is supported on, but separate from, a second Bourdon tube S2 to be referred to presently), to a diaphragm 47 (Fig. 6) to move the valve member 58a, thus causing variation of pressure in a tube U leading to a pressure-gauge G, recording device D, or a pressure switch S. Pressure in the tube U is also applied, via channel 25a, to a feed-back Bourdon tube S2 the tip deflection of which is such as to move the nozzle 27 the correct amount to maintain linearity of the back pressure variation with the input pressure variation. The separation between nozzle 27 and the flapper valve F may be varied by rotation of the latter about a vertical axis.

Title: Improvements in net-making machines
IPC: D04G1/00
Filed: 1922-07-03
Abstract: 209,119. Goold, L. W., (Yamamoto, T.). July 3, 1922. Net-making machines; netted fabrics and netting.-Knotless netting is made on a machine in which spindles 7 carrying yarn are arranged on the inside of a cylindrical platform provided with holes in which are mounted shafts 4 carrying star-wheels 6, 6<a> and discs 3. The holes in the platform are so placed that the spindles 7 can be driven round between them and the discs 3 in serpentine paths by the star-wheels, which are arranged in a line of flattened S-formation and are operated by bevel gearing &c. from a main driving shaft. The twisting of the yarns together to form meshes is performed by the alternate star-wheels 6 each of which take round a pair of spindles 7 the number of times necessary to form meshes of the desired length. As the spindles revolve on the wheels 6 pinions 10 mesh with stationary racks and by rotating the spindles put a twist on the yarns. The meshes are interlocked by the exchange of spindles on the alternate star-wheels 6a, the wheels 6 being stationary. Groups of adjacent meshes as shown in Fig. 9 are twisted in the same direction, but the direction of twist is reversed at intervals and the interlock is made as shown in Fig. 20. The edge twines are made from stronger yarns which do not traverse and are interlocked as shown in Fig. 21. The interlocks are tightened by means cf a reciprocating plate with V-shaped slits through which the meshes pass. The netting is taken up by a series of rollers geared together, the lowest roller being provided with hooks. The end meshes are caught on the hooks by a camactuated hooking device.

Filed: 1937-01-21
Abstract: 494,226. Printing processes. MATUSCHKE, W. Jan. 21, 1937, No. 18232/36. [Class 100 (ii)] In a process of printing metal plates are used to replace rubber printing-plates adapted to print from inks which are solutions or dispersions of organic dyes, or mineral dyes in volatile solvents. The invention consists in a method of printing from a metal printing-forme, which comprises preparing a forme in which the printing-surfaces lie accurately in a plane, or in a cylindrical surface, freeing the forme from grease and polishing it, applying an ink formed of pigment dissolved or suspended in a volatile solvent by means of an accurately cylindrical inking roller but with very slight pressure, and printing from the inked forme with very slight pressure. Screened printing-plates with unusually deep etching may be used as the printing-formes. The process is carried out in an ordinary printing-press used for rubber printing-formes in which ink is taken by an applying roller from an immersed roller which dips into the ink box.

Title: Improvements in or relating to electrical musical instruments
IPC: G10H3/10
Filed: 1932-06-28
Abstract: 403,444. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., Chase Road, Willesden, London, and BOURN, L. E. A., 22, Stanwell Road, Ashford, Middlesex. June 28, 1932, No. 18235. [Class 88 (ii).] In an electrostatic musical instrument an undulating potential, which is preferably transmitted through an amplifier to a loud speaker, is produced by relative movement between an electrode and a charged phonic member. Fig. 1 indicates the method of production of a single note. A stationary ring 3 of undulating formation is charged, on closure of a key contact 7 and a stop contact 9, through a potentiometer resistance 5. An electrode 4 rotates over the ring 3 at a speed controlling the frequency, and is connected to the amplifier 1 and loud speaker 2. In the complete instrument there are twelve similar discs comprising groups of rings 3, each disc bearing, on the edges or surfaces of concentric rings, sine-wave forms corresponding to a note and its octaves and all the harmonics thereof. The twelve rotating arms 4 are geared together in the ratio 12#2. Where different partials of different octaves of a note are of the same pitch only one ring 3 on a disc is provided. Provision is made for sixteen partials in the five lowest octaves, and for ten in the highest octave. The rings for corresponding partials of all notes are connected to the same one of sixteen busbars 6 (Fig. 2, not shown). A key 8 in the five lowest octaves makes contact on all the busbars, but only those partials of the note are sounded for which the corresponding bus-bars have been energized by the drawing of a stop 10 carrying the requisite combination of contacts 9 (Fig. 3, not shown). The contacts 9 are connected to different points on the potentiometer resistance 5 so that the various partials are sounded with the correct relative intensity, high resistances 13 being interposed to prevent short-circuiting. The same discs may be connected to a number of keyboards. The rings are earthed through leak resistances 11 so as to discharge when a note is to cease. The effects of bells, sustaining, reverberation, &c., may be obtained by stops controlling the value of the resistances 11 (thereby controlling the rate at which the potential fades) or throwing in condensers 14 in parallel with the resistances 11 (thereby causing a less percussive attack).

Abstract: 865,775. Protective cut-out arrangements. GENERAL ELECTRIC CO. Ltd. June 2, 1959 [June 9, 1958], No. 18361/58. Class 38 (5). In a balanced-voltage feeder protection system having comparator means adjacent each end of a protected section and arranged to be operated in dependence upon the current flowing in a closed loop pilot circuit and to be restrained against operation in dependence on the resultant voltage across the pilot circuit in the manner of an impedance relay having a substantially circular resistance/reactance characteristic, each comparator means includes an impedance arranged so that when the power flow is from the adjacent end, the current to which a comparator means is responsive is the sum of the currents flowing round the closed loop and through the impedances so as to offset the characteristic along the resistance axis to reduce the response of the comparator means to apparent capacitive impedance of the pilot circuit. In Fig. 8 each comparator means comprises a relay having an operating winding 7 and a restraining winding 12 which acts as the impedance. In Fig. 11 each comparator means comprises a relay having its single winding 24 wired in a comparator circuit comprising full wave rectifiers 28, 29, the rectifier 28 being connected in series with the pilot circuit and the rectifier 29 being connected to the secondary winding 30 of a transformer having its primary winding 33 connected across the pilot circuit as shown and constituting the impedance referred to above. A non-linear resistance 15 reduces the reach of the relay under heavy throughfault conditions. Reference is also made to the use of a transistorised comparator.
