Title: Process for the manufacture of titanium dichloride
Inventor: COOPER MICHAEL JOHN
IPC: C01G23/02
Filed: 1958-07-11
Abstract: Titanium dichloride is prepared by reacting titanium tetrachloride vapour with a mass of particulate aluminium at 400 to 475 DEG  until the aluminium constitutes not more than 95% of the mass which is then contacted with titanium tetrachloride as a fluidized bed at above 475 DEG C. but not exceeding 650 DEG C.  The titanium tetrachloride may be mixed with a gas inert under the reaction conditions, preferably argon.  According to a typical example, a bed of aluminium fluidized with argon was heated to 400 DEG C. in an externally heated reactor and titanium tetrachloride was introduced until the aluminium content of the bed fell to 89%, after which the bed temperature was raised to 550 DEG  and the titanium tetrachloride vapour flow was increased. Aluminium chloride effluent was recovered and the bed ultimately consisted of free-flowing black titanium dichloride containing about 1% of aluminium compounds.  The reaction may be effected in a plurality of fluidized beds by passing the aluminium particles in countercurrent to the titanium tetrachloride vapour successively through a plurality of fluidized reaction zones.  The temperature of the first zone or zones may be from 400 to 475 DEG C. until the aluminium connect of the fluidized material has decreased to below 95% and the reaction is completed in later stages operating at 475 to 650 DEG C. and preferably not above 550 DEG C.

Title: Improvements in and relating to lubricating apparatus
IPC: F16N25/02
Filed: 1951-09-25
Abstract: 698,297. Lubricating. SCHMEMANN, sen., A., and SCHMEMANN, jun., A., [trading as DE LIMON FLHUME & CO.]. Sept. 25, 1951 [sept. 25, 1950; May 22, 1951 ; June 19, 1951], No. 22408/51. Class 12 (iii). A lubricant distributer is connected by two pipe-lines with a central pumping apparatus, and comprises a control piston 3 and a conveying piston 7 which are moved alternately by the hydraulic pressures in these lines, the piston 3 being acted upon on one side by thin oil under periodically varied pressure supplied from one pipe-line 12 and on the other side by the constant pressure of a second medium, for instance grease, supplied from the second pipe-line 13, one of the two media being delivered to the lubricating points as a lubricant. In Fig. 1, the pump (not shown) has placed the oil line 12 under pressure and set the pistons as shown, the constant pressure of grease in the line 13 having been overcome. The grease now passes through duct 14 to the left-hand side of the piston 7 to move it to its right-hand extreme position and expel grease through the duct 11 and the connection 16. A control apparatus (not shown) then relieves the pressure in line 12 so that the piston 3 is moved to the right under the pressure from line 13, the channel 14 being connected to the duct 11 so that the piston 7 is moved to the left to displace grease via duct 10 and connection 18. If the piston 3 is reversed, the distributer may be used to supply oil instead of grease to the connections, so that several distributers in a single installation may be arranged to supply oil or grease to bearings.

Abstract: 775,435. Solenoid-operated valves. WELT, B. P., MASLOW, M., and KREITCHMAN, M. A. Aug. 3, 1954, No. 22470/54. Class 135. A solenoid-operated valve comprises a valve body 26, Fig. 1, having an inlet passage 31 and an aligned outlet passage 31a mounting a seat nipple 25 engageable with a sealing member 24 loosely mounted in an elongated recess 45 in a transverse bore 22 of a plunger 20. Inlet pressure acts on the rear face of the member 24 to urge it into engagement with the seat. On the energization of a solenoid 10, the plunger 20 moves upwardly against a spring 19 to open the valve, the plunger moving initially with lostmotion with respect to the sealing member to strike the latter and break the seal between the member 24 and the seat 25. In a modification, two outlet passages 32,.33, Fig. 5, are provided. In the upward position of the plunger 39, the inlet passage 43 communicates with the passage 32 and in the downward position thereof with the passage 33. In a further modification, a seat nipple is fitted in each of the passages 31, 31a, and the sealing member 24 carried by an axially disposed lug of the plunger is engageable with either nipple depending upon the direction of flow through the valve.

Title: Device for controlling air flow as a function of temperatures in a space
IPC: F24F11/76
Filed: 1963-06-06
Abstract: 986,219. Valves. RANCO Inc. June 6, 1963 [June 11, 1962], No. 22543/63. Heading F2V. [Also in Division F4] A device for controlling air flow to a space in accordance with temperature comprises thermally responsive power means acting through a lever 34 on a pivoted arm 31 carrying an air flow control baffle 16, the arrangement being such that a restraint on the baffle will not prevent movement of the lever under the influence of the power means. As illustrated, the device is applied to a refrigerator in which air from a cooling unit is supplied through a duct 12 to a food compartment and returns to the cooling unit through a duct 13, the device controlling the air flow from the duct 12. The temperature in the air outlet from the food compartment is sensed by a capillary tube 17 containing a volatile fluid and communicating with a hollow element 55 formed of two dished metal diaphragms. A post 56 mounted on the element 55 bears against a knife edge 57 on the lever 34 to turn it with rising temperature about a triangular fulcrum pin 35 against the bias of a spring 37. The bias of the spring 37 over-rides that of a spring 33 coiled round the pivot 32 of the arm 31 carrying the baffle 16 and having its ends connected to that arm and to the lever 34 so that it biases the arm 31 towards the open position of the baffle and moves it towards that position with rising temperature. Decreasing temperature allows the spring 37 to return the baffle through the lever 34. The temperatures at which the baffle opens and closes may be adjusted by means of a spring adjusting screw 41 and a knob 53 which moves a cam 50 to pivot a lever 43 holding the head of the screw 41. The device may be used in cooling or heating systems for rooms or buildings.

Abstract: 1,137,635. Filing strips. EASTMAN KODAK CO. 20 Dec., 1965 [25 Jan., 1965], No. 22549/68. Divided out of 1,137,634. Heading B6E. The description is the same as that in Specification 1,137,634, but the claims refer to the strip separating fork comprising a base portion 37, two legs 36, 38, one of L-shape, and each with a strip contacting edge (41, 42) one being located above and in front of the other. Pieces of film 11 in sheet or short strip form and bearing information, are secured separately at their front ends on a stepped pad 13 so that their rear ends are exposed in overlapping formation 14, and the pad is slidably mounted in a holder 15 in a selector apparatus. The pad 13 is engaged by a lug (29), Fig. 6, not shown, on a member (27) which has a further lug (28) engaging a helical groove (24) in a cam (23), whereby when the cam is rotated by a knob (22) and pre-set according to an indicator (26) on the knob, the pad 13 is disposed in a selected position in the holder 15. In the latter position of the pad, the free end of a particular film 11 is disposed below the separator device which is guided for vertical movement produced by a rack and pinion means (45, 46) operable by a rod and knob (47, 48). As the mounting descends, one edge (42) on leg 36 engages and depresses all the film pieces below the piece to be selected, and edge (41) on the leg 35 rests on the free end of the selected film. Thus, when the pad 13 is moved towards the mounting (34), by rotating the knob (22), the deflected films are directed downwards, and the films overlying the edge 41 are directed upwards, and the selected film can then be located and positioned in registry with an optical axis (18, Fig. 5) for viewing without physically removing the film from the pad 13.

Title: Improvement in steam turbines
IPC: F01K19/08
Filed: 1931-08-12
Abstract: 381,656. Steam turbines. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Vasteras, Sweden. Aug. 12, 1931, No. 22806. Convention date, Aug. 12, 1930. [Class 110 (iii).] Relates to the use of high-pressure steam for maintaining the pressure in an extraction pipe. The Figure shows a turbine 2 working against a constant back pressure, regulation being effected by a valve 4 responsive to the exhaust pressure and also to speed. The pressure in the extraction pipe 13, which is fed by pipes 6, is kept constant by a pressureresponsive valve 8. At low loads the extraction steam is compressed and augmented by an ejector 11 which is fed from the main steam pipe 1. This supply is controlled automatically by a pressure-responsive valve 14. The ejector may be replaced by a pump driven by an engine the exhaust of which is passed into the pipe 13. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement shown in Fig. 2 (Cancelled), in which exhaust steam from a turbine 17 is compressed by live steam in an ejector 25 with which steam it mixes for re-use in the turbine. When this supply is insufficient for the load the speed governor opens a valve 20 which admits live steam direct to the turbine. This subjectmatter does not appear in the Specification as accepted.

Abstract: 430,777. Making bronze powders. KRAMER, E., 73, Sõchsischestrasse, Berlin. Aug. 9, 1934, No. 23073. Convention date, Aug. 9, 1933. [Class 100 (ii)] [See also Group II] Metal powder from a pounding-machine is carried to a sifter by a wind stream, the separated powder is precipitated, e.g. by a cyclone separator, and is then led directly to a polishing- machine which is not traversed by the wind stream. Material such as metal shavings, powder, or waste foil, is delivered from a container 7 by a rotary hopper 8 and is carried through a ball mill 1 by a stream of air or inert gas from a blower 14. The powder now in the form of small flakes is then carried to a sifter 10 from which the finished flakes pass to a cyclone separator 17 while the remainder return to the mill 1 for further grinding : the sifter 10 is one without sieves, and a mixed powder is therefore provided. The powder is delivered from the separator 17 by a hopper 19, passes into a polishing-device 20 comprising rotary brushes 24, and is delivered into a receptacle 26. A gas such as nitrogen with a small percentage of oxygen may be introduced into the apparatus at 28 so as to travel in the opposite direction to the powder and provide an oxide coating during polishing, most of the oxygen being thereby absorbed ; the gas then passes via a byepass 37 into the wind stream, a device 35 being set to release gas at a predetermined pressure. If the pounding-machine, sifter, and separator are to be operated with a gas filling independently of the polishing-drum, gas is introduced by a pipe 30. The pressure in the apparatus is slightly above atmospheric to avoid admission of air. Grease may be introduced at 27 for the pounding operation and at 32 for polishing. Specifications 341,561, 341,562, and 373,784 are referred to.

A limit switch operated by a monitor arm 11 has to be reset manually by a push-button 27 but resetting is prevented until the arm 11 is restored to its non-operated position. The arm 11 is secured to a shaft 9 carrying a seal ring 13 and a cam disc 10 which has a recess 10a normally accommodating one end of a rod 25. Rod 25 is slidable in fixed cross-members 20 and 23 but is stable only in its two end positions due to two leaf springs 26 arranged as an overcentre toggle mechanism as shown. The other end of rod 25 engages a push button 27 moulded in rubber-like material with a flexible skirt sealingly fitted into an aperture in the switch casing. When arm 11 is operated by the movable member to be monitored recess 10a cams the rod 25 sufficiently to make it snap to its other stable position wherein it forces the button 27 to stand proud of the casing (Fig. 3b, not shown). The disc 10 then prevents the rod 25 being moved back over dead-centre until lever 11 is returned to bring recess 10a in line with the rod, whereupon manual pressure on button 27 will make the rod snap back again. Switch units 30, such as those described in Specification 872,030, are provided and have movable contact strips 33 carried by spring-loaded insulator rods 32 which are engaged by cross-members 28 and 29 on the rod 25 such that the movement thereof causes contacts 33 to be snapped into and out of engagement with fixed contacts (not shown). Arc blow-out means are preferably provided as described in Specification 853,162. Instead of cross-members 28 and 29 the rod 25 may be provided with fingers engaging with lost motion in elongated slots in the insulator rods 32.
