Title: Vehicles
IPC: B62D5/09
Filed: 1971-04-19
Abstract: 1345591 Vehicle steering DEMAG AG 19 April 1971 [16 April 1970] 27130/71 Heading B7H A heavy vehicle, e.g. a container straddle loader comprises two spaced wheel frames 1 each on a respective longitudinal side of the vehicle and each supported on a group of four road wheels 3. Each wheel 3 is mounted in a vertically pivotable fork 2, the cross-piece 14 of which forms a two-armed lever to one end 6 of which is connected a steering ram 15 and to the other end 6 is connected a tie rod 5 which links with the further forks 2. A valve 10 controls flow of fluid from pump 7 to cylinders 16 which are arranged so that the front wheels steer oppositely to the rear wheels. The fluid lines 17, 18 of each side 12, 13 are interconnected by lines 19 while the tie-rods 5 of each side are connected by lever 23. In a modification, the two sides of the vehicle may have separate hydraulic systems controlled by two valves 10 which are linked. The tie-rods 5 of each side may be connected by a slave control valve instead of lever 23. In a further modification a single valve 10 supplies fluid to one side of the vehicle, while the slave control valve which connects the two sets of tie-rods 5 also controls flow of fluid to the other side of the vehicle. The vehicle may also have an automatic steering system by means of sensors 34 which scan an induction cable in the ground and control the electronic valves 10. Non-steerable wheels may be provided between the front and rear steerable wheels.

Title: An improved combined two-speed gear and back-pedalling brake for cycle hubs
IPC: B62M11/16
Filed: 1937-10-07
Abstract: 503,238. Coaster hubs. STEVENS, A., H. (Mussehnan, A. J.) Oct. 7, 1937, No. 27251. [Class 136 (ii)] [Also in Group XXIV] In two-speed coaster and brake hubs for cycles, the driving-sprocket 1 is held in place against a ball-bearing 6 in the hub by a flange 4 on the worm 3 operating the driving freewheel clutch and brake and by a disc 11 formed on the sun-wheel 12 of an epicyclic gear of which the planets 9 are supported on the worm 3 and the annulus is formed within the sprocket 1. A sliding brake-cone 17, carrying pins 27 sliding in the disc 11, is adapted to be brought into engagement with a stationary cone 16 for low speed, and the pins 27 may be engaged with the sprocket 1 for direct drive. By removing the cone 16 and the sleeve 14 on the central axle on which it is secured, the gearing and the worm 3 may be removed for replacement by a suitable standard combined sprocket and worm. The cone-clutch nut 44 carries teeth 43 for engagement on back-pedalling with teeth 42 on a sleeve prevented from rotation and moved axially by such action to press wedges 40 between brake segments, which are thus expanded against the hub.
Patent GB-868399-A (GB)
Title: Improvements in and relating to the inoculation of liquids flowing in pipes
IPC: C02F1/68
Filed: 1959-08-10
Abstract: 868,399. Liquid dosing apparatus. SCHMITT, P. Aug. 10, 1959 [Aug. 8, 1958; June 6, 1959], No. 27290/59. Class 86 In a dissolving and dosing apparatus for supplying a constant proportion of a softening or other reagent to a flow of water, the reagent is contained in a chamber A the pressure in which is above that in the mixing chamber C during operation, but below when the flow of water is stopped by a valve downstream of the apparatus, thus preventing over-dosing. Granular polymeric phosphate is placed on the porous diffusion layer 7 in the chamber A to which water is admitted by the duct 4, forming a concentrated phosphate solution which diffuses through the layer 7 to provide a saturated solution in the space B. The main flow of water enters the apparatus through a non-return valve 1 and passes through a nozzle 2 which creates a zone of reduced pressure in the neighbourhood of the aperture 3 connecting with the mixing chamber C; as the duct 4 and chamber A are supplied with water of inflow pressure through a pressuresensitive valve 5, phosphate solution passes from chamber B to the mixing chamber C through passage 14, adjustable needle valve 6 and non-return valve 11. The pressure in chambers A, B is equalized without time-lag by means of the connecting tube 8 and perforated sphere 25. The pressure-sensitive valve 5, see Fig. 3 (not shown) is set so that when water is flowing in the main, the valve is open as shown in Fig. 3 and admits water to duct 4. If, however, the flow is stopped by closing a valve in the main downstream of the apparatus, the consequent rise in pressure of the main will close the valve 5. The duct 4 and chamber A will then be isolated at the pressure obtaining during flow, while the pressure at valve 1, nozzle 2, aperture 3 and chamber C will rise to the new mains pressure, preventing any outflow of reagent through the non-return valve 11. The non-return valve 1 isolates the apparatus from any drop in mains pressure during non-operative periods. The chamber A and porous layer 7 may be incorporated in a refill cartridge, see Fig. 5 (not shown).

Title: Bakery pan registration control system
IPC: A21C9/08
Filed: 1974-06-20
Abstract: 1446373 Automatic control of deposition of dough pieces on pans AMF Inc 20 June 1974 [9 Oct 1973] 27347/74 Heading G3N Relates to an arrangement for controlling the positioning and movement of baking pans and the deposition of dough pieces at one or more predetermined locations on each pan. The arrangement comprises a dough piece dispenser 10, Fig. 1 which dispenses a row of for example four dough pieces at a time, transversely of the direction of a baking pan conveyer belt, there being a constant time interval between rows, and the conveyer belt speed is controlled as a function of the dispensing rate, the conveyer drive motor 26, Fig. 3 being energized by a tachogenerator coupled to the shaft of a dough cutting drive motor 16. The conveyer moves the pans at a high speed until the leading pan 20a is sensed by a proximity detector PRS- 1 whereupon a solenoid SOL 1 is energized to cause a retractable conveyer to be moved into working position. When the pan arrives at the dispensing position, as sensed by a proximity detector PRS-2 a relay r13 is momentarily energized causing energization of relays r14, rl4A which lock-in and cause the conveyer motor to move the conveyer belt at a slower speed. At the same time a clamping means is activated by a solenoid SOL 2 to clamp the pan 20a stationary against a guide rail (32) Fig. 2 (not shown) while the conveyer belt continues to move below it. A cam 2 continuously rotates in synchronism with the dough cutting motor shaft, and has a 'high' cam surface portion which is arranged to switch a switch LS 2 to its position (a) at the time the dispenser 10 releases dough pieces whereupon energization of relays r16, r15 causes de-energization of SOL 2 hence release of the clamp. The pan now proceeds at a slow speed and a counter 54 counts the number of rows dispensed. When this number equals a desired number pre-set on a selector 56, the latter produces an output to an AND gate 52. At this stage the gate 52 is also receiving an input via relay contacts r17a,b so that it produces an output to reset the counter 54 via a delay circuit 62 and to energize a relay 23. The normally closed contacts (1)(4) of relay 23 open, de-energizing relays 14, 14A, 15, 16, 17 and 23. The deenergizing of 14A switches a resistor R3 across the conveyer motor instead of R4 causing it to move the pans at the higher speed, moving pan 20a away and bringing the next pan into the desired initial registering position detected by PRS-2. The process is then repeated. Alternatively PRS-2 may be arranged to detect the rows of dough piece receptacles or cups instead of the leading edge of a pan.

Title: Improvements in steering mechanism for dirigible craft
IPC: G05D1/02
Filed: 1922-10-11
Abstract: 209,799. Jackson, P. R., (Sperry Gyroscope Co.). Oct. 11, 1922. Steering and manoeuvring automatically.-In steering-gears for dirigible craft means actuated by the rudder are provided for determining and establishing automatically the mean position of helm, that is a virtual central position which may or may not coincide with the true central position and which takes account of winds, tides and like forces tending to force the ship off its course. For establishing mean helm, the rudder 43 is connected by an adjustable link 150 to a segment 151 freely mounted on a spindle 152 above a larger segment 155. This segment 155 has rods 156, 157 extending therethrough, the lower ends having rollers 158 adapted to move over cams 160, 161 when the segment 155 is moved and the upper ends having ratchets whereby the worm 170, Figs. 5, 6 and 8 is rotated to move the segment 151 and thus the rudder relatively to the large segment 155. For small resultant forces in one direction the rudder is thus held on a new virtual centre Z Z. The ordinary contacts 86, 91 - - 97 used in connection with the rudder head in the automatic steering gear described in Specification 214,561 are now similarly placed with reference to the segment 155 when the mean helm device is used.
Patent GB-860378-A (GB)
Title: Improvements in or relating to the production of b-trichloroborazols
IPC: C01B35/14
Filed: 1959-08-12
Abstract: B-Trichloroborazole is prepared by reaction of dry boron trichloride gas with ammonium chloride particles in a dry, heated, fluidized bed and is condensed in a substantially completely moisture - free atmosphere.  The ammonium chloride particles together, if desired, with inert solid particles, e.g. magnesium turnings, glass or tower packings to increase agitation in the bed, decrease the agglomerating tendency of the ammonium chloride, and increase the yield of B-trichloroborazole, are fluidized by a dry gas, e.g. N2, air, A, CO, CO2, O2 or HCl (gas) or, in a modification of the process, with the boron trichloride gas itself, and are heated until substantially moisture-free.  Boron trichloride gas, if not already present as the fluidizing gas, is then introduced into the bed in any amount up to 100% of the incoming gases.  Reaction temperatures of 120-350 DEG  C. in the fluidized bed may be obtained by an electric heater and the fluidizing gas and boron trichloride gas or boron trichloride gas alone, if acting as the fluidizing gas, may be pre-heated to about the same temperature as the bed which is preferably at 150-170 DEG C.  The B-trichloroborazole produced is removed from the bed in the stream of fluidizing gas and/or residual boron trichloride gas and is isolated by condensation, for example in a series of water-cooled condensers.  The residual boron trichloride gas leaving the condensers may be recycled to the system.
