Title: Improved packing and slicing machine for comestibles
IPC: B26D7/06
Filed: 1931-01-31
Abstract: 364,879. Cutting fish &c. ATLANTIC COAST FISHERIES CO., 111, John Street, New York, U.S.A.-(Assignees of Taylor, H. F. ; 111, John Street, New York, U.S.A.) Jan. 31, 1931, No. 3150. Convention date, Feb. 1, 1930. [Class 5 (i).] A machine for producing steaks from fish fillets or other soft comestibles comprises a number of screws 16 arranged circularly, Fig. 7, to form a trough-like space 20 into which the fish pieces are placed, the screws acting to compact the mass and feed it through an aperture 25 where it is wrapped spirally by a ribbon supplied from a reel 72 which is rotated planetarily around the issuing mass. The wrapped mass is then moved by an endless conveyer 96 towards a rotary knife 118 having a cutting edge in the form of a helical spiral, the knife cutting the mass into steaks. The screws 16 are interconnected by gear wheels so that they rotate alternately in opposite directions necessitating alternate screws being of opposite pitch. The threads are rounded at the tops and bottoms and the spaces between them are filled by strips 26. The conveyer 96 is tensioned by a screw-adjusted roller 103, and is driven by bevel gearing 110, 111 from the shaft 43. The knife is driven by bevel gearing 137, 134 from the same shaft, the gearing, shafting and supporting brackets being adjustable to permit the necessary repositioning of the knife when the effective diameter of the knife becomes smaller owing to grinding. The knife 118 is sprung into position on a helical support 115 and is secured thereto by screws. The wrapped mass is guided towards the knife by side strips 113 and is supported at the cutting position by a troughlike member having a groove which receives the knife edge at its largest diameter. To prevent lubricants from contaminating the food, bearing surfaces may be of lignum vitµ or other material not requiring lubricant.

Abstract: 1375073 Valves KOEHRING CO 24 Jan 1972 [2 Aug 1971] 3198/72 Heading F2V A valve element 7 governing the connection of service passages 8, 9 with a supply passage 13, 14 and a return passage 15 is biased to the neutral position shown by a spring S and may be held in a pair of working positions by a detent 30 which is released by a plunger 31 responsive to a predetermined pressure in a supply passage of the valve. The element is first moved manually to a position in which the detent 30 engages a cavity 35 and fluid from supply passage 13, 14 flows through a check valve 24, a bridge passage 16 and a port 11 to a ram which has its opposite end connected to the return passage 15 through a port 12 and passages 21, 19 and 22. When an increase in pressure occurs in passage 13, for example due to the ram piston reaching the end of its stroke, bores 38, 36 communicate the increased pressure to a valve 40 and the plunger 31 which is thus displaced against a spring 32 to release the detent. The spring S now displaces the element 7 to a position in which the detent engages a cavity 34, the connections to the ram are reversed and the bore 38 is in communication with the passage 16. The detent is again released and the element 7 returned to neutral when the ram reaches the end of its return stroke or a rise in supply pressure occurs. In a modification, the element "holds" the ram when in neutral instead of allowing it to "float".

Title: Improvements relating to the manufacture of an additional material for hard-soldering and welding purposes
IPC: B23K35/30
Filed: 1933-02-02
Abstract: 400,817. Uniting by fusion ; soldering. KANZ, H., 17, Letzigrabenstrasse, Albisrieden, Zurich, Switzerland. Feb. 2, 1933, No. 3222. Convention date, Feb. 4, 1932. [Class 83 (iv).] A copper-containing hard solder or welding material in rod or wire form is composed of two or more different alloys, one at least of which is produced in such form by mechanical shaping so as to form at the joint an alloy of melting point materially lower than that of copper and which cannot itself be made by mechanical shaping. For soldering brass, a low melting point solder containing zinc with 42 per cent of copper, which cannot be obtained in wire form by pressing, rolling or drawing, is produced at the joint by forming by mechanical shaping a wire of a copper zinc alloy containing more than 58 per cent of copper and thus of high melting point and filling or coating it with zinc. Coating may be effected by electrolysis, dipping, sherardizing, or by pulling one or more zinc tubes over the wire. For making a filled wire, a brass tube may be filled with a zinc or zinc alloy wire or with molten zinc or zinc alloy and drawn down into wire form. Such a wire may be further furnished with a metallic coating. Silicon, aluminium, magnesium, or manganese may be added to prevent oxidation or evaporation of the solder. The high melting-point alloy may thus consist of 62À5 per cent of copper, 37 per cent of zinc, and 0À5 per cent of silicon.

Abstract: 1427864 Excavators POCLAIN 24 Jan 1974 [25 Jan 1973] 03286/74 Heading E1F [Also in Divisions Fl and F2] In the circuit shown in Fig. 1 a relief valve 10 opens at a first pressure when both the pumps 13, 14 are connected to a ram 1 and opens at a second higher pressure when the pump 14 only is connected to the ram 1. With a valve 30 in the position shown the output of pumps 13, 14 is connected to either chamber 2 or chamber 3 of the ram 1 by a manually operated valve 4. If valve 30 is moved to connect the output of a pump 32 to lines 29, 28, a valve 19 is moved by pilot pressure in ram 21 to connect the output of pump 13 to the reservoir 9 and pressure of the ram 12 causes the overload valve to remain closed until a higher pressure is reached in the line 8. Fig. 2 shows the construction of the valve 10. When both pumps are connected to the ram a closure member 39 is held against a seat 38a by resilient washers 11. If only a single pump is delivering, pressure in a line 28 moves a piston 42 to the left and the pressure exerted by the piston is added to that of the washer 11 by a member 44 which abuts a stem 39a. As described, the ram 1 raises the boom 51, Fig. 3, of an earthworking machine.

Abstract: 986,583. Welding by fusion. LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCROS Jan. 29, 1962 [Feb. 6, 1961], No. 3354/62. Heading B3R. [Also in Division H5] In a constricted arc torch having means for passing an inert gas such as argon over the free end 2 of an electrode 3 and through a hollow electrode 5, the latter is provided with oblique passages 15 the axes of which intersect the axis of the electrode 5 near the outlet aperture 17 thereof, and a further gas which may carry a powder for use in welding workpieces 18 is introduced through the passages 15. The axial position of the electrode 3 in a conductive guide 6 is controlled by rotating a knob 7. Argon is fed through a tube 12 and passes through grooves 13 in the guide 6 to a space 14 between a refractory insulating member 28 and the end 2 of the electrode 3. The electrodes 3 and 5 are shown schematically as connected directly to a generator 22. In practice these connections are effected by conductors 23 and 24 fixed to the inlet pipe 32 and outlet pipe 33 of a fluid coolant system comprising chambers 29 and 30 connected by a rubber pipe 31. In the arrangement shown there are four passages 15 with their axes intersecting at a point. In a modification (Figs. 4 and 5, not shown) a wire of metal to be deposited and which may contain a flux, is fed to this point through a further passage. Alternatively (Figs. 6 and 7, not shown) the wire may be fed laterally at the exit of the electrode 5. Further modifications consist of connecting the passages 15 in opposed pairs to separate gas sources (Figs. 8 and 9, not shown) or providing two sets of passages of different inclinations whose axes intersect the axis of the electrode 5 at the same point (Figs. 10 and 11, not shown). The electrode 3 is of refractory metal or alternatively of a fusible metal which is fed continuously to the arc.

Filed: 1944-02-23
Abstract: 591,451. Making grids for thermionic valves. M-O VALVE CO., Ltd., CRAIG, R. H., and MEDCALF, W. H. Feb. 23, 1944, No. 3360. [Classes 83 (ii) and 83 (iv)] Welding.-In a machine for making grids for thermionic valves and the like, two metal rings are supported on a mandrel and molybdenum wire is fed automatically to one ring and spot welded thereto after which the mandrel is displaced and the wire spot welded tor a second ring and cut, leaving a length protruding from the wire feed means sufficient to be welded to the first ring after the mandrel has been indexed for the next operation. The mandrel 1, Fig. 1, is carried on a spindle 2 threaded at each end 3, 4 to receive nuts 13, 14. The first ring 11, Fig. 2, is located against a shoulder 6 by a thin cylinder 7 which has slits 8 at its free end and is attached at the other end to a sleeve 26 so that it can be drawn towards the shoulder to accurately position ring 11 by rotating a handle 9 on a member 28 having internal screw-threads 27 engaging threads on sleeve 26 ; whereafter the handle may be locked. A second ring 12 having an inturned flange is then located against a disc 5 on the mandrel with its open end facing ring 11 and nut 13 is screwed on to threads 3 to locate the flange of ring 12 between it and disc 5. Nut 14 is then rotated to draw the disc and ring 12 into the correct position with relation to ring 11. The mandrel has a recess 24 to receive a brush 25, Fig. 3, completing the welding circuit through the ring being welded and an electrode 21 disposed perpendicular to the mandrel axis. A bobbin 16 contains the grid wire 15 which is fed through diamondfaced jaws in a member 17 and a guide tube 18. The electrode descends to weld the end of the wire to ring 11 and the slide 22 containing the mandrel is then displaced to bring ring 12 into welding position and members 17 and 18 are moved towards the bobbin, about pivot 19, to expose a length of wire sufficient for a second grid wire to be welded after the first is secured. The electrode again descends, welding the wire to ring 12 ; and a knife 20 which has reciprocating motion parallel to its axis then cuts part way through the wire so that the ring is not scored ; the wire being completely severed by its own tension. The mandrel is then indexed by a ratchet-wheel and displaced to bring ring 11 back to the welding zone for attaching the end of the next grid wire. Welding current may be controlled by a gas-filled relay and its associated circuit and the first fitting of ring 11 may be accomplished by a cylinder similar to, and fitted in the manner of, the ring 12 having sufficient length so that before the disc abuts the mandrel the ring is positioned on the shoulder 6. This setting cylinder is then replaced by the ring 12.

Filed: 1953-02-03
Abstract: 731,472. Automatic voltage control systems. GENERAL ELECTRIC CO., Ltd., and BRYER, R. F. Feb. 5, 1954 [Feb. 3, 1953], No. 3423/53. Class 38 (4). In an automatic tap-changing voltage control system, the system is periodically unbalanced in alternate directions, but correction is only effected when the voltage deviation causes the system to remain unbalanced regardless of the periodical unbalancing arrange - ment. A voltage proportional to the output is rectified at 2, Fig. 1, and applied to a bridge which includes lamps 3, 4 and resistors 6, 7. The bridge is periodically unbalanced by switching a resistor 8 into alternate arms by a camoperated switch 9. A polarized relay RL/1 is connected across the bridge and the circuit constants are so arranged that when the output voltage is correct, relay RL/1 changes over its contacts RL1, each time switch 9 changes over, but when the voltage deviation exceeds a predetermined amount the unbalance of the bridge causes contact RL1 to remain stationary regardless of the position of switch 9. Contact RL1 energizes one or another of a pair of solenoids 18, 19, Fig. 2 which control a pawl 16 on an arm 12 oscillated by the same cam 11 as operates switch 9, and so phased with respect to switch 9 that under normal voltage conditions when the solenoids 18, 19 are being alternately energized, the pawl armature 15 is nearer to the unenergized solenoid and hence is not attracted to cause the pawl to engage the ratchet wheel on the tap changer. When one of the solenoids is continuously energized, the pawl armature is attracted and the pawl engages to rotate the tap changer in the corrective direction.

Title: Improvements in or relating to methods of or means for measuring or comparing the light scattered by particles in illuminated media
IPC: G01N21/51
Filed: 1919-02-12
Abstract: 137,637. Pollard, A. F. C. Feb. 12, 1919. Photometric apparatus.-Relates to apparatus for measuring light scattered from small particles in a solid or fluid medium, and consists in means for collecting all the light scattered at a definite angle to the axis of the incident beam and directing it in such a manner that its intensity can be measured either directly or by comparison methods. In the apparatus shown in Fig. 1, the scattering-medium, contained in a cylindrical cell or ground and polished to cylindrical shape, is placed in a cavity 1 at the centre of a reflector 2 consisting of a frustum of a right cone which reflects the light scattered in a plane at rightangles to the axis of the incident beam and directs it on to a similar frustum 3 which reflects it on to a highly-polished right cone 4. The intensity of the beam reflected from the cone 4 may be measured directly, or it mav be compared with that obtained from a similar apparatus containing a standard light-scattering medium through which part of the incident beam is passed. The generators of the cone 2 may be straight lines inclined at any desired angle, or they may be curved lines such as parabolas or ellipses; the generators of the cone 3 may also be curves. Fig. 5 shows an arrangement for comparing the scattered light with that scattered from a standard medium, in which a second frustum 5 surrounds the standard medium, and the frustum 3 collects the light from both the frusta 2, 5, the face of the frustum 5 being covered by an optical wedge. Instead of this arrangement, a single frustum split along its diameter may be employed, the two half-frusta being at different positions along the axis of the instrument. In order to compare the intensity of the scattered light with that of the incident beam, the cone 4 may have a central aperture through which the incident beam passes. Alternatively, part of the frustum 3 may be cut away and the corresponding part of the cone 4 bevelled off, the incident beam being reflected on to the plane part of the cone, as shown in Fig. 8. In a further modification, only the upper halves of the frusta 2, 3 and cone 4 are used, and the scattered and direct beams are directed by reflecting and refracting prisms so as to be in juxtaposition in the field of view.
