Abstract: 807,245. Fork lift trucks. CLARK EQUIPMENT CO. Oct. 15, 1956, No. 31313/56. Class 78 (3). [Also in Group XXIX] In a fork lift truck having double-acting actuators for tilting the uprights and the actuation of an auxiliary device, and a single-acting actuator for elevating the loadsupporting carriage, a dual unit pump has one discharge line connected to an inlet 30 of the valve assembly, and the other discharge line connected to an inlet 34. Valves 72, 74 have grooves 44, 48 and 50, 54 leading to double-acting actuators, actuation of one of the valves opening its grooves respectively to the inlet port 30 and exhaust so that the associated actuator is supplied by one pump only. A valve 78 has a groove 60 leading to a single-acting actuator, and a handle 126 for actuating the valve also operates a valve 76. Moving handle 126 clockwise causes valve 78 to close an outlet port 86 and to open groove 60 to the inlet port 34, valve 76 being simultaneously moved to open a path from inlet 30 to valve 78 so that both pumps supply the actuator. The valve unit may be enclosed in a casing and all exhaust liquid be returned to a sump through a return line, alternatively the valve unit may be mounted in the sump.

Title: Improvements in or relating to perforation sensing apparatus
Inventor: WOODHEAD JAMES
Filed: 1958-10-01
Abstract: 917,348. Sensing statistical records. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Aug. 19, 1959 [Oct. 1, 1958], No. 31326/58. Class 106 (1). A perforated record 1 is sensed by pins 4, one for each column or row position, each pin being controlled a spring 9 and an eccentric stud 6 moving in a slot 8. As the stud 6 rotates the pin 4 moves towards the record, passing through a hole if one is present, to bring an arm 10 into line with a slider 11. Continuing rotation of the stud moves the lower end of the pin member sideways so that the arm 10 displaces the slider 11 and closes contact 13. If there is no hole present the pin member cannot move to align the arm 10 with slider 11 so that the contact 13 is not closed. If the tape is moving when sensed, the pin member tilts about the stud 6 while it is engaged with a perforation.

Means for disengaging a latch 24 holding a door 12 comprises an operating rod 21 actuated by a piston 40 enclosed in a casing 39, the piston being operated by fluid supplied through pipe 38 and flexible tubing 46 from another piston enclosed in a casing 37 placed on the ground, the latter piston being operated by a pivoted lever 33 which is moved, in the case of a garage door, by the wheel of a vehicle passing over it. The door is biased to an open position by a spring 31 or by a counterweight and a lever 18 allows the door to be opened manually. The piston rod 42 of the piston 40 has secured to it a hollow tube 43 within which the end of the operating rod 21 slides so that after the piston 40 has moved to disengage the latch it can then be returned to its original position by the spring 41 without further moving the latch. A reservoir 47 with a one-way valve 50 feeds the system in case of leaks and a bleeding point is provided in the ground-sited casing 37.

Abstract: 1,175,988. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORP. 1 July, 1968 [17 July, 1967], No. 31423/68. Heading G4H. In a keyboard controlled typewriter a record of the position of a printing head with respect to the paper is up-dated in two ways: (1) as the printing head is letter-spaced forwards or backwards along a line a horizontal position word is repeatedly augmented or decremented by unity, the word being reset to zero whenever a cariage return signal occurs, and (2) when the printing head is tabulated to a new position, the horizontal position word is compared in turn with an ascending sequence of pre-stored words representing the positions of those tab stops that have been set, until the first one which is greater than the horizontal position word is found, whereupon this tab stop word is taken as the new horizontal position word. Tab stop words are also available from store in reverse order so that backward tabulation is possible.

Title: Improvements relating to method and apparatus for reducing silicon steel strip
IPC: C21D8/12
Filed: 1954-11-01
Abstract: In a process for producing grain-oriented silicon steel strip of high magnetic permeability, cold-rolling of the strip is preceded by hot-rolling a slab into strip by repeated passes back and forth in a mill, the temperature between successive passes being controlled by heating in furnaces to impart the optimum texture for rendering the subsequent grain orientation most effective and the time intervals between successive passes being regulated to allow the grains to recover from plastic deformation. The hot-rolled strip is annealed in an oxidizing atmosphere at 1600 DEG F., treated in a pickling solution of 10 per cent sulphuric acid and 5 per cent hydrochloric acid at 160 DEG -190 DEG F., cold-rolled to 0,025-0,035 in., annealed in a reducing atmosphere in a muffle furnace at 1600 DEG -1800 DEG F., cold rolled to 0,012,0,014 in., annealed in a reducing atmosphere at 1300 DEG -1800 DEG F. and finally batch-annealed at 2100 DEG F. in a hydrogen atmosphere.  The steps of rolling of the ingot to slab form followed by re-heating and of annealing before pickling may be omitted.

Abstract: 1,146,546. Velocity-modulated tubes. SIEMENS A.G. 14 July, 1966 [15 July, 1965], No. 31574/66. Heading H1D. In an E-type travelling wave tube, in which a strip-shaped electron beam is projected on to a helical path along a delay line in the electrostatic field provided by a cylindrical capacitor, the electron gun includes an apertured accelerating anode 5; a cathode 1 having an emitting surface positioned perpendicular to the anode and to one side of the aperture; a deflecting electrode 7 positioned parallel to the cathode surface but on the opposite side of the beam path; and a set of beam-forming electrodes, a first one of which, 9, is positioned between the cathode surface and the anode, and a second of which, 10, is positioned between the cathode surface and the deflecting electrode 7. The strip beam is formed by a slot aperture 3 in the modulating electrode 2, the additional electrode 11 permitting fine adjustment of the beam path, and variation of the potential of the deflecting electrode 7 permitting adjustment of the exit angle of the beam from the gun. In modified arrangements, the angled electrode portions 6 and 8 may be replaced by separate electrodes, and the cathode may have a concave emissive surface. Disturbance of the beam by the transitional electric field between the gun and the drift space field produced by the cylindrical capacitor, of which one electrode (16, Fig. 2, not shown) is in the form of a slow wave structure, is reduced by the provision of a parallel plate capacitor (14) through which the beam passes after its emergence from the gun. The relative potentials applied to the various electrodes are given.

Abstract: 986,159. Steroids. BOEHRINGER INGELHEIM G.m.b.H. Aug. 21, 1962 [Nov. 21, 1961], No. 32062/62. Heading C2U. Saponins and sapogenins are recovered from the liquid obtained by fermenting juices expressed from Agave sisalana by blowing air through the liquid to concentrate the saponins and sapogenins in a surface foam, separating chew liquid from beneath the surface foam and recovering the saponins and sapogenins from the surface foam and, if desired, hydrolysing the saponins to sapogenins. Flotation and wetting agents may be added to the liquid before the treatment with air. The above process may be repeated in which case water may be added to the separated foam before air is passed through the liquid. The crude surface foam product may be dried to separate the saponins and sapogenins, for example at a temperature of 80‹ to 150‹ C., which heating may be continued after the drying process is completed. The dried material is better suited to subsequent saponification. In an example, the dried sediment obtained by the above process is acid hydrolysed, treated with milk of lime and then hecogenin extracted which is acetylated to hecogenin acetate.

The oscillation frequency is a measure of the flow-rate, and may be determined by making the oscillating body interrupt a light beam. In fig. 1 the flow through conduit 10 is indicated by arrows 52, 53; the pivoted body is a sharp edged plate 22, which pivots about an axis normal to the drawing. The pivotal motion is limited by stops 34, 36. A light detector is seen at 50, and a light source (not shown) is mounted above it so that the plate can break the path between the source and detector. The apparatus may measure How-rates from or to the lungs of a human patient, e.g. for diagnosis. A digital counter may be used to display the flowrate. The detector signal may be integrated to give the total flow.
