Filed: 1956-06-07
Abstract: 809,164. Levels. ENIS, F. B. D'. June 7, 1956 [Aug. 31, 1955], No. 17675/56. Class 97 (2) In a level of the pendulum type the pendulum is pivoted about the axis of symmentry of an annular magret system which damps its movements, pendulum and magnet being relatively axially adjustable. As shown in Fig. 5, the pointer 4, moving over a scale 9, is secured to a spindle carried in bearings 6, 7. A disc 8D, attached to the spindle, moves over the face of an annular magnet 10 and carries a weight in the form of a mercury capsule 8C. The effective separation of the magnet 10 and disc 8D may be varied by adjusting the magnet, by substituting a disc of different thickness or adding an extra disc 8E. In the form shown in Fig. 1, the pendulum 8 hangs within the magnet system, or it may hang past the end face with a cylindrical end portion projecting in proximity to the outer face of the magnet. A further cylindrical portion may project within the magnet. The casing 1 carries tangential straight edges 2, 3. The magnet may be formed of two juxtaposed horseshoe portions. A cam-operated device may be provided to centre the spindle within the magnet system.

Abstract: 731,640. Endless track vehicles. McEWEN, C. L. June 25, 1953 [July 14, 1952], No. 17703/53. Class 79(1). [Also in Group XXX] In an endless track tractor of the kind in which the track frames 4 are mounted on a dead axle 3 and are connected to the front of the tractor body by a leaf spring (not shown), a U-shaped scoop carrying frame 11 is pivoted to the tractor body at 12 and is luffed by a pair of double acting rams 14 which are supported on the frames 4 by brackets 13. The pivots 12 and dead axle 3 are carried by a frame 2 secured to the tractor body and are so spaced that when the loaded scoop 9 is raised the tractor body pivots clockwise about the axle 3. A pair of rods 18, each pivoted to one bracket 13, and slidable through a hole in a bracket (not shewn) on frame 2 are provided with adjustable abutments adapted to engage the brackets on frame 2 so limiting this movement of the tractor body and temporarily locking together the track frames and tractor body to increase the stability of the machine. When the scoop is unloaded the abutments do not contact the brackets on the frame 2 and thus the track frames are free to pivot independently about the dead axle 3.

Title: Improvements relating to the dielectric heating of materials
Inventor: BARNES HERBERT ROY
IPC: H05B6/78
Filed: 1962-05-09
Abstract: 1,016,435. Microwave heating apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 11, 1963 [May 9, 1962], No. 17875/62. Addition to 893,936. Heading H5H. [Also in Division H1] Dielectric heating of material is effected by radio frequency energy in a waveguide 5A or cavity which is terminated at each end in an effective open-circuit 5B, the energy being supplied at approximately the cut-off frequency for the waveguide or cavity which is then " tuned " to cut-off at this applied frequency, In the form shown, the terminations are sections 5B of waveguide of greater depth G2 than the depth G1 of the main portion 5A which is provided with choked slots for the passage of strip material to be heated. Energy is fed by way of coaxial cables 19 and 17 to a loop 15 enclosed in a dome 21, e.g. of P.T.F.E. The inner conductor of the coaxial cable 17 consists of a group of wires spaced around the periphery of a circle so that the end of the inner conductor together with the loop 15 can be rotated through a small angle. Coarse tuning of the waveguide 5A is effected by a longitudinal rod 23 eccentrically mounted on spindles 25 one of which carries a knob 27 and pointer 29. Fine tuning is effected by a longitudinal rod 33 mounted on rods 35 which are coupled to the operating shaft of a thrust motor (not shown). The difference in signals provided by two probes 39 spaced #/4 along the feeder 19 in the presence of standing waves due to the waveguide 5A being off-tune is fed to a coil of the motor to reset the fine tuning rod 33 automatically. A stabilizing negative feed-back signal proportional to the rate of change of position of the rod 33 is obtained from a second coil in the thrust motor. Limit switches associated with the rod 33 provide an indication by coloured lamps when resetting of the coarse tuning rod 23 is necessary. This may be effected manually or automatically.

Filed: 1932-06-24
Abstract: 403,663. Tumbler switches. JOHNSON, J. Y., 47, Lincolns Inn Fields, London.-(Arrowhart & Hegeman Electric Co. ; Hartford, Connecticut, U.S.A.) June 24, 1932, No. 17902. [Class 38 (v).] A snap-action switch has an operating member 44 fixed on a spindle 49 and operatively connected by a transmission spring 60 to a switching member 16 rotatable on the spindle and having a contact button 17 at its lower end. A pin 64 on the switching member engages an aperture in a locking plate 70 which is pressed by a spring 80 so that teeth on its edge engage recesses 74 on a fixed frame plate 31. Thus the switching member 16 and plate 70 can only rotate together. A plate 76 fixed on the spindle 49 has struck up lugs 78 which engage similar lugs on the locking plate 70 to move it axially out of engagement with the recesses 74 and allow the switching member 16 to rotate. In action the operating member is moved thus straining the spring 60, until the operating member reaches its final position when the plate 76 engages the locking plate and allows the switching member to move until arrested by the teeth on the locking plate engaging the next set of recesses 74. Two sets of fixed contacts 20, 22 are provided thus giving two switching positions and a central zero position. Reference has been directed by the Comptroller to Specifications 21037 /11, 253,223, and 332,025, [all in Class 38 (v), Electric switches &c.].

Abstract: 745,051. Electrolytic production of titanium tetrahalides. BRITISH TITAN PRODUCTS CO., Ltd. June 29, 1953 [July 16, 1952], No. 17971/52. Class 41. Titanium tetrahalide is prepared by electrolysis of a fused metal halide salt bath in which the anode comprises a mixture of titanium compounds, containing at least 90 per cent titanium dioxide, and carbon, the halogen liberated at the anode reacting with the titanium dioxide to form titanium tetrahalide. The fused salt may be potassium chloride, bromide, iodide or fluoride, sodium chloride, bromide, iodide or fluoride, calcium chloride or magnesium chloride, or a mixture of two or more of these, preferably having the same halogen radical. The electrolysis may be carried out in a bath heated to 700 to 1400 C., using a tantalum, graphite or iron cathode, or a liquid cathode of zinc or cadmium. The anode and cathode may be separated by a diaphragm, such as a porous pot, or by a non-porous barrier immersed below the electrolyte surface. The titanium compound may be a synthetic oxide or a natural oxide such as mineral rutile, mineral brookite, or mineral anatase, and may be mixed with charcoal or coal. The mixture may be contained in a porous pot with a carbon rod inserted therein, or the mixture may be bonded with gum, pitch or glue and a carbon rod inserted into the mass; the mixture may also be made into a paste with glycerine or dehydrated castor oil, shaped, dried and baked, with or without a carbon core, or the paste may be fed on the top surface of a decaying anode which is progressivelv lowered into the bath. The titanium tetrahalide gases, such as titanium tetrachloride, are withdrawn from above the anode, with carbon monoxide and dioxide, and condensed.

Title: Improvements in the Oil-Hydraulic Control of Stepwise Movements for the Rapid Acceleration of Large Masses
IPC: F15B11/00
Filed: 1968-04-17
Abstract: 1,176,318. Forging manipulator control. SCHLOEMANN A.G. 17 April, 1968 [29 April, 1967], No. 18048/68. Heading B3H. [Also in Division F1] In an hydraulic system wherein an hydraulic motor 9 is required to impart stepwise movement to a load having a high inertia, e.g. a workpiece gripped by manipulator tongs during forging, the supply to, and exhaust from opposite sides 8, 10 of the motor are cut-off at the end of a step by closure of a valve 2, the consequent build-up in pressure on the exhaust side 10, due to the inertia of the load, being relieved through a pressure-limiting retardation valve 14 and a by-pass line 15 to the supply side 8. The system thus causes the supply and exhaust sides 8, 10 of the motor to remain under a residual pressure so that when the next step is initiated by opening of the valve 2, the pressure in the exhaust side collapses while the supply side is still under an initial pressure. When the valve 2 is opened, a valve 3 is also opened so that exhausted liquid by-passes the limiting valve 14 and a non-return valve 13 to flow to a return line 12. A non-return valve 1 in the by-pass line 15 is opened when the valve 2 is closed. The motor 9 may be a double-acting piston and cylinder type or, as shown, a rotary motor. The system described is duplicated to enable stepwise movement of the motor to be reversed. The valves 1, 2, 3 may be electrically or mechanically operated.
