Abstract: 155,684. Ranbach, B. Oct. 16, 1919. Traversing-cutter type. - In cardboard boxes of the matchbox type having the sides slit near one end so that when partly open the end of the box may be bent down to expose the cigarettes &c., the two slits are made simultaneously, while the box is held on a slotted block, by knives carried by slides operated by links and a hand-lever. Fig. 4 shows part of the block a on which the box, previously scored on the line where it is to be bent, is placed in an inverted position. Its top edges are rounded to facilitate the positioning of the box. At each end of it is an inclined slot c opening into a bore c' for receiving and giving escape to the waste material. Corresponding knives f, Fig. 3, mounted on slides e, register with the slots. The slides are worked by links g connected to a hand lever at opposite sides of its pivot so that when this is rocked the knives are simultaneously operated. More than one slit may be made in each side, and piercings of other shape may be produced, for instance, thumb holes.

Title: Improvements in or relating to the extraction of titanium from its halides
Inventor: QUIN JAMES PATERSON
IPC: C22B1/08
Filed: 1951-11-01
Abstract: 717,930. Extracting titanium IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 31, 1952 [Nov. 1, 1951; June 11, 1952], Nos. 25566/51 and 14691/52. Class 82 (1) Titanium tetrachloride is reacted with sodium in an inert atmosphere at a temperature between 200‹C. and the melting point of sodium chloride, preferably at 480‹-620‹C., whilst maintaining in the reactor an agitated, non-adherent, particulate bed of reaction products, titanium being thereafter recovered from such products. Before recovering the titanium, the reaction products may be heat treated above 800‹C. in an inert atmosphere. The sodium chloride may be extracted by heating with water or with a 1 per cent. aqueous solution of sulphuric acid, or may be volatilized in an inert atmosphere at a temperature above the melting point of titanium which is then removed in massive form. The vessel 1, Fig. 1, is half filled with powdered sodium chloride free from oxygen and nitrogen and heated, whilst stirring, to 500‹ C. Molten sodium is then fed through the pipe 6 and liquid titanium tetrachloride through the pipe 7, air in the vessel having been replaced with argon through the pipe 5; reaction products are removed at 10. In a modification, Fig. 2, argon is circulated by the blower 2 through the reaction. vessel 1 which contains graded steel balls 5 on a grid 4, the balls supporting a bed 6 of reaction products.

Patent GB-1343244-A (GB)
Title: Magnetic pulse compression radio-frequency generator apparatus and method
IPC: H02M7/523
Filed: 1972-06-01
Abstract: 1343244 Inverting MEGAPULSE Inc 1 June 1972 [12 Aug 1971] 25659/72 Heading H2F [Also in Divisions H3-H5] A radio frequency generator comprises two or more pulse generators each having a saturable magnetic pulse compressor at its output; the outputs are connected together to supply a load, positive part cycles being supplied by one generator and negative part cycles by another. To avoid interaction between the generators the pulse compressors are arranged to have a low output impedance when delivering current and to have a high output impedance at all other times. Fig. 1 shows two pulse generators, of which only the one in the upper half of the figure will be described. When SCR 11  is triggered the capacitor C 11 , which was previously negatively charged by source B # , is positively charged to a value slightly under 2E dc  + B # , the exact value depending on losses in inductor L 11  and the SCR and capacitor. This charging occupies time T 1 , Fig. 2, and raises the capacitor voltage to e c11 , SCR 11  becoming reverse biased and switching off  after a delay of T REC1 . SCR 21  is then triggered, and the charge on capacitor C 11  is passed to capacitor C 21  which was previously charged by voltage B 2 . B 2  is of a lesser magnitude than B # . A rise in voltage e c21  thus occurs on capacitor C 21  as seen in Fig. 2. This capacitor is connected to a saturable reactor SR 11  which is normally fully saturated in a negative direction by bias current I B , but as charge from the capacitor flows through the reactor it is driven to positive saturation and it becomes a very low inductance. When this happens the current rises rapidly, and a pulse i 3  is delivered to the transformer T 11  and thus to load Z L . This pulse is of duration # 3 , giving a pulse compression ratio of # 2 /# 3 , Fig. 2. The capacitor C 21 , saturable inductor SR 11  and the load are matched, so that they form an under - damped resonant circuit, which results in diode D 11  being reverse biased after the discharge. This provides a high output impedance during that part of the cycle when the generator in the lower half of Fig. 1 produces a pulse. Only two basic generators are shown in Fig. 1, but the number required to produce a continuous wave oscillation of period T is given by T/# 3 . This number can be reduced with a high Q load at the expense of output amplitude ripple.

Title: Improvements in heavy oil carburettors
IPC: F02M15/02
Filed: 1934-09-07
Abstract: 444,020. Charge mixing devices; vaporizers. RUGEL, J., and LUTZ, A., (trading as RUGEL & LUTZ MASCHINENFABRIK), Ravensburg, Wurtemberg, Germany. Sept. 7, 1934, No. 25773. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 11, 1935.] [Classes 7 (ii) and 7 (iii)] Unvaporized fuel in the mixture delivered by a carburetter is projected against the walls of a pipe i, jacketed by exhaust gases, by a centrifuging wheel e, which has a central imperforate portion l disposed transversely to the direction of flow of the mixture. The upper and lower parts of the vanes of the wheel are bent to form parts d<1>, d<3> which draw in the mixture and which force it into a chamber k whence it passes to the engine. The wheel e may be driven by a pulley a or by a wheel, having inclined vanes, rotated by the suction of the engine. A valve m allows a petrol carburetter to be used at starting. In a modified construction, the walls of the pipe are spirally corrugated and the pipe contains several single wheels each having a central imperforate portion around the periphery of which the vanes are attached. The fuel may be preheated before entering the carburetter by passing through an exchangeable insertion in a tube passing through the exhaust pipe. The drawings of the Specification as open to inspection under Sect. 91 show also a modified form of wheel. This form does not appear in the drawings of the Specification as accepted.

Abstract: 1492108 Disc brakes; hydraulic brake cut-off valves EATON GmbH 18 June 1975 [22 June 1974] 25875/75 Headings F2E and F2F  In a vehicle such as a fork lift truck, a disc brake assembly arranged between two of the vehicle wheels comprises pairs of opposed pistons 13, separate conduits 22, 26 for supplying hydraulic fluid to chambers 18 between the pistons, and axially movable discs 9, 10 which are acted on by the pistons so as to brake the wheels. As shown, the discs are urged into contact with fixed pads 11 on wheel drive transmission parts 5, 6 and the pistons carry pads 14, from pairs of pistons being provided. Conduits 22, 26 are supplied with fluid either from a tandem master cylinder or, as shown in Fig. 3, a single-stage master cylinder having a spool valve 24 at its outlet arranged to cut off the supply to the line in the event of leakage in that line. Normally fluid from chamber 28 passes through bores 45, 46, chambers 43, 44 and outlets 23, 27 to the conduits but in the event of a significant pressure drop in the latter, the pressure in one of the chambers 43, 44 will exceed that in the other and the spool 35 will move accordingly. A projecting part 38 of the spool is arranged to operate a signalling switch 50 in this event.

Title: Device for regulating room temperatures
IPC: H05B1/02
Filed: 1971-04-19
Abstract: 1350153 Temperature regulators ZENTRA ALBERT BURKLE KG 19 April 1971 [2 April 1970] 25995/71 Heading H1N In a room temperature regulator having a bimetal 12 controlling a microswitch 16 with a large switching differential, the bimetal is provided with an anticipatory heating or cooling element 18 and is cyclically rocked by a cam 10 to reduce the differential. The bimetal 12 is supported in contact with the operating button 15 of the microswitch between two pivot points 13, 14. Point 13 is fixed by a temperature setting cam 20 while point 14 is moved by the cam 10 through a follower 25. The cam 10 has a low portion 32 entry of the follower 25 into which is limited by a stop 31 set so that the total deflection of the bimetal by cam 10 is a little greater than the switching differential of switch 16 so that if the room temperature is near to the set value the switch 16 will be switched off during each cycle of the cam. The differential of the switch 16 is made deliberately large so that once the switch is on the room heater 19 cannot raise the temperature fast enough to switch it off again during the cycle of the cam. In addition a further step 43, 45 may be provided on the cam of sufficient depth that the bimetal cannot cool fast enough to overcome the deflection it causes before the end of the cycle so that the switch cannot be switched on during the latter part of the cycle. The steep rise 40 at the beginning of each cycle means that unless the temperature is very close to the set value the switch 16 is switched on close to the beginning of the cycle. Thus, in heating the room, the regulator switches the heater on for whole cycles of the cam but there is a small proportional range close to the set temperature. Since the switch cannot be switched on during the latter part of the cycle the regulator is suitable for controlling gas and oil fired boilers which must be on for a minimum period. For electric heating the step 43, 45 may be omitted. If room heater 19 is replaced by a cooling plant of an air conditioning system the heating element 18 is replaced by a cooling element, e.g. working by the Peltier effect. The cam 10 may be driven by the motor of a timeswitch associated with the heating or air conditioning system.

Abstract: 802,081. Reaping machines. BOMFORD, D. R. Sept. 13, 1956 [Sept. 13, 1955], No. 26219/55. Class 6(3). Apparatus, e.g., as described in Specification 738,765, for cutting vegetation on banks or hedges at the sides of roads, has a reciprocable cutter blade 11 mounted on a bracket 13 with a bearing 14 encircling a shaft 15 so that the cutter blade and fixed blade 12 may be swung upwards about the shaft by a lever 19, for variation of the inclination of the blades. In such apparatus a plate 31 is mounted on a bearing 24 at one end of a connecting rod 25 (which forms part of the drive by which the blade 11 is reciprocated), or is mounted on the blade itself adjacent the bearing 24. The plate 31 therefor reciprocates with the blade 11 and applies a similar movement to any cuttings approaching the bracket 13 so that their accumulation on the bracket 13 and on a cranked lever 23 is avoided. The plate 31 may be adjustably mounted on a rod secured to the end bearing 24 of the rod 25. A crank pin on the driving shaft 15 drives through a link 20 the cranked lever 23 which has a pivot pin 29 journalled on the bracket 13 and which carries a pin bearing in the end 24 of the rod 25 which is thus reciprocated to drive the cutter blade 11 through a bracket 28 on the blade. A tubular cross-bar 10 for supporting the blades and their mechanism is mounted on a tractor and may be moved up or down. The Provisional Specification describes also the plate disposed at right anglse to the blade or in the same direction as the bracket.
