Title: Traps
IPC: A01M23/26
Filed: 1958-03-24
Abstract: 864,265. Animal traps. ANIMAL TRAP CO. OF AMERICA. March 24, 1958 [March 29, 1957], No. 9308/58. Class 5(1). An animal trap comprises two frame members 10 and 11 having their end members 18 and 26 pivoted to each other so as to be rotatable about a common axis, and a spring 13 having at its ends two ring members 32 and 33 adapted to engage the end members 18 and 26 of the frames one on each side of the common axis. The action of the spring 13 is such as to force the ring members 32 and 33 apart, thereby pivoting the frame members to their " spring " position and trapping an animal. The trap is held in its " set " position by a detent 12 comprising a first trigger member 34 and a second such member 35. The first member 34 comprises a closed loop 40 threaded over the frame 11, and a closed hook 37 which is hooked over the frame member 10 when the trap is in its " set " position. The second trigger member comprises a portion 36 threaded through the closed hook 37, and a depending bar 41, the portion 36 being placed between the frame member 10 and the member 34 as shown in Fig. 4, with the result that when an animal interferes with the bar 41, the portion 36 prises the hook 37 off the frame member 10 and the trap is released. The member 39 of the detent, when positioned as shown in Fig. 4, prevents the movement of the hook 37 away from the frame member 10 and therefore serves as a safety device.

Title: Improvements in range-finding apparatus
IPC: B64D1/04
Filed: 1943-06-10
Abstract: 572,816. Range-finders. WALLIS, B. N. June 10, 1943, Nos. 9375 and 9446. [Class 97 (i)] [Also in Group XXI] A range-finder for a torpedocarrying aircraft comprises two transparent mirrors T<1>, T<2>, Fig. 1, pivotally movable in opposite directions about parallel axes, the angle between the mirrors being adjusted to an angle supplementary to the known angle subtended at the eye by a target C of known dimensions and being further adjusted to take account of variables such as size, speed and direction of movement of the target, speed of own aircraft or the state of the water surface. Fig. 1 shows the approach positions P<1>, p<2>, P<3> of the attacking aircraft, the position P<2> being the optimum position when the target is calipered by the rays from a source of light carried near the eye of the sighter. Fig. 5 shows a front view of the apparatus with the levers 29, 30 and knob 27 for adjusting the angle between the mirrors 15, 16 in accordance with scales on a dial 31. The apparatus is mounted for lateral and other adjustments on a ball joint at the end of a fixed arm situated near the windscreen of the craft. The mirrors are mounted on vertical pivots 17, 18, Fig. 3, and are interconnected by pin-andslot means for opposite movement when the arm 20 on pivot 18 is operated by an adjustable cam 22 against the action of a spring controlling an arm 25 on the other mirror pivot 17. The cam is mounted by a sleeve 28 on a eccentric portion 261 of shaft 26 carrying the push-pull knob 27, the two positions of which register separate cams with the arm 20 for attacks in rough or calm seas. The lever 29 adjusts the sleeve for varying ground speeds of the aircraft and the lever 30 rotates the cam to suit various sizes of target. If the target is not at right angles to the line of approach and is therefore foreshortened, the knob is turned to appear approximately parallel to the target, the eccentric 261 then conveying movement to the cam. A dark glass 33 may be adjusted to a position in front of the mirrors. By polishing the mirrors in closely-pitched parallel lines the single point of light appears as a line in each mirror between which lines the target is readily calipered. Specification 504,845 is referred to.

Title: Improvements in or relating to cemented carbides
IPC: C22C29/10
Filed: 1957-03-22
Abstract: Cemented carbides, especially for cutting tools, are made by grinding TiC in an oxygen- and nitrogen-free medium (e.g. benzene, hydrogen, vacuum, the inert gases, petroleum ether), mixing therewith finely divided Mo and at least one iron group metal, compacting the mixture, and sintering it at a temperature sufficiently high to establish a liquidus phase and in a nitrogen- and oxygen-free medium while on a support which is incapable of imparting to the compact any nitrogen or oxygen. The metals are preferably also ground in a N-free and O-free medium, whilst the support may be graphite, carbon or TiC. The carbide may be ground in a ball-mill to an average particle size of 1m , and the metals similarly.  In an example 65 per cent TiC is mixed with 35 per cent metals (comprising 75 per cent Ni, 25 per cent Mo) a lubricant such as stearic acid being added; the mix is cold pressed at 25,000 lb. per sq. inch, pre-sintered in hydrogen at 1200 DEG F for about 1 hour and finally sintered in a vacuum of 0.2m  of mercury at about 2500 DEG F on a graphite stool for 2 hours.

Title: Improvements in methods for the production of acetylene from calcium carbide
IPC: C10H21/00
Filed: 1943-06-11
Abstract: <PICT:0587567/IV/1> The temperature in the drum of an apparatus for the production of acetylene from calcium carbide is reduced by cooling a portion of the quantity of the acetylene gas leaving the drum (e.g. in the ratio of 3 c. ft. to 17 c. ft.) and returning it to the drum. Advantageously, the apparatus comprises a horizontal drum rotated within a casing and containing the calcium carbide on which water is sprayed.  Preferably, the gas is conveyed back to the drum only when the drum is rotating and the same motor may be used to effect the conveyance of the gas and to rotate the drum.  In one example, the cooling means adapted is based on the counter-current principle.  In the Figure, a perforated drum a rotating in the casing d contains lumps of carbide b which are sprayed with water through nozzle c, the acetylene so generated leaving by pipe e. Part of the acetylene generated leaves by pipe e1, by the action of the blower o, and is cooled by passage through coil h and water trap k1 before being returned to the drum to cool the acetylene being generated therein.

Title: A process for continuously reacting finely divided solids with liquids and/or gases
IPC: C07F5/06
Filed: 1957-03-22
Abstract: A reaction between solids and liquids and/or gases is conducted in the liquid phase in a reactor A full of liquid wherein the reactor is divided by means of screening plates X with perforations of such a size that at any given speed of gas stream, gas-buffers are formed underneath the screening plates, resulting in the liquid being impeded in its path from the solid/liquid inleg g through the reactor, maintaining a uniformly distributed solid in the reaction space.  An inert gas or an inert liquid may be used to provide the liquid/gas buffer in reactions in which the phase would normally be absent.  A solution of iron pentacarbonyl in petroleum, free from iron particles, can be produced by circulating carbon monoxide through the reactor with finely divided iron suspended in petroleum.ALSO:<PICT:0809310/IV (b)/1> Aluminium is reacted with olefins and hydrogen to produce aluminium trialkyls, the reaction being conducted in the liquid phase in a reactor (A) full of liquid wherein the reactor is divided by means of screening plates (X) having perforations of such a size that at any given speed of gas stream, gas-buffers are formed underneath the screening plates, resulting in the liquid being impeded in its path from the solid/liquid inlet (g) through the reactor and maintaining a uniformly distributed solid in the reaction space.  An inert gas or an inert liquid may be used to provide the liquid/gas buffer in reactions in which the liquid phase would normally be absent. Exemplified products are aluminium tri-isohexyl, aluminium triethyl, aluminium di-ethyl hydride.  In Example (4) finely divided magnesium in di-isobutyl ether is reacted with bromobenzene to yield phenyl magnesium bromide.

Title: Rolling mill frame with pre-stressed tie rods and rolling gap control
Inventor: METZGER SIEGFRIED
IPC: B21B37/64
Filed: 1967-03-01
Abstract: 1,135,715. Rolling. VERWALTUNGSGESELLSCHAFT MOELLER UND NEUMANN OFFENE HANDELSGESELLSCHAFT. 1 March, 1967 [9 March, 1966], No. 9705/67. Heading B3M. [Also in Divisions G2 and G3] A pre-stressed rolling mill has tie-rods 3 between upper and lower frame parts 1, 2, rigid spacing members 12, 13 on each tie-rod between the parts, and hydraulic pressure units 30, 32 urging the members away from the lower part 2. The spacing members for each tie-rod comprises a non-rotatable nut 12 and a screwthreaded member 13 which is driven by a drive wheel 14 from a worm drive 18. The prestressing is effected by hydraulic fluid in the pressure space 20. The mill frame may bo relieved by admitting fluid to the space 25 under the piston. The pressure units between the frame parts each comprise a ring piston 31 mounted on the tie-rod and a cylinder 30 preferably in the lower frame part 2. A sensing device 50 is connected to a piston 31 and when the piston moves from its required position under load it sends signals electrically to a coil 46b which controls an electro-hydraulic servo valve 46 to alter the flow of fluid to the cylinder 30. To alter the rolling gap the fluid is bled from the spaces 21 and fluid admitted to spaces 25 through a valve 41 controlled manually by a time relay. As the pressure in spaces 20 drops the pistons 31 move causing the device 50 to emit a signal which is compared with a nominal value from a device (60) in a comparator (61), Fig. 2 (not shown). The resulting error voltage is fed to the coil 46b of the control valve 46 until the error voltage is zero. The position of the piston 31 is held constant and the gap may be altered by the screw-down device. After adjustment the valve 41 is actuated to bleed fluid from the space 25 and fluid is admitted through a one-way valve 37 to the space 20 to prestress the frame. The pre-stressing is at least 1¢ times the rolling pressure. Since the rolling gap may not correspond to the desired strip thickness a strip is initially inched between the rolls and a second sensing device 60 is connected to a thickness measuring device (67). An error voltage is produced in the comparator (61) which affects the control valve 46 so that the pistons 31 are moved until the voltage is zero. The sensing device 50 is then adjusted to keep the pistons in this position. The measuring device (67) may remain connected to the comparator (61) to allow for roll wear or the temperature of the slab. In an alternative arrangement, Fig. 3 (not shown), the control valve is connected to the sensing device 50 initially and then connected to a telescopic sensing device 51, 52 which measures the distance between the chocks 6, 7. The arrangement is used similarly to the first arrangement using a strip thickness measuring device (67).

Title: Electric Motor Heating Unit
Inventor: BLAIR DARRELL JASPER
IPC: H02K15/12
Filed: 1969-02-24
Abstract: 1,187,759. Switching circuits. M. & B. ELECTRIC CO. Inc. 24 Feb., 1969, No. 9722/69. Heading H2H. An arrangement for keeping an electric motor warm during the period when it is switched off includes a switching circuit for applying a reduced voltage to the windings of the motor, the switching being delayed until the motor has come to rest after switching off. As shown in Fig. 2, the motor 10 is energized by a threephase supply at terminals L1, L2, L3 through a main switch MS. This switch co-operates with a further switch PS so that when the switch MS is closed, switch PS is open and vice versa. Hence, when the motor is turned off by opening switch MS, switch PS closes to energize a transformer T. Connected across the secondary winding 14 of the transformer, there is a time delay device 17 which, after a predetermined time longer than the time taken for the motor to come to rest, closes a switch 17<1>. A relay R is now energized and switches S1-S4 are closed. Hence, a voltage is applied to lines 20, 21, 22 which are connected to the input terminals of the motor. This voltage is selected from tappings on the transformer secondary, and is chosen so that the current in the motor windings is of the order of one-fifth of the rated current. Sufficient resistive heat is now produced to maintain the temperature of the windings 15- 20‹ C. above the ambient temperature and to prevent atmospheric condensation. When the motor is next used, closure of the main switch MS immediately opens switch PS, de-energizing the transformer T and the relay R. Should any of the contacts S1-S4 stick, the circuit is protected by fuses F1, F2.

Title: Improvements in or relating to glazed ceramic articles
IPC: C04B41/86
Filed: 1963-03-12
Abstract: A glaze slip which forms a gel when applied to an uncoated ceramic article comprises a ceramic glaze composition and cellulose crystallite aggregates having a level-off D.P. or their water-insoluble and/or organic solvent-insoluble derivatives, the aggregates or their derivatives having a particle size of from less than 1 micron to 300 microns, at least 1% by weight having a particle size not exceeding 1 micron.  Cellulose crystallite aggregates are made by controlled acid hydrolysis of cellulose (Specifications 874,945, 970,111 and 970,112).  Many hydrophilic and hydrophobic derivatives of the cellulose aggregates are specified.  The glaze slip may be applied by dipping, spraying or brushing to baked or unbaked ceramic articles, and provides a firm gel surface so that a patterned overglaze (which may or may not contain the cellulose aggregates) may be applied without blurring or intermixing.  The article may be fired after each application of glaze or after both glazes have been applied.  In an example, 10% by weight of a dry glaze formulation is added to an aqueous slurry containing 10% by weight of aggregates.  The glaze is applied to a tile.  A patterned overglaze (also containing cellulose aggregates) is then applied to the gel surface, and the tile is fired.
