IPC: B60B9/20
Filed: 1920-07-22
Abstract: 166,823. Martin, J. July 22, 1920. Spring wheels with continuous outer rigid ring and pneumatic hubs.-A resilient wheel is provided with a solid tyre .21 of a suitable material such as steel, and the resilience is obtained through sliding spokes 6 having each an outer flange 10 and an inner flange 5 resting on a pneumatic tyre 4; this rests in a rim 3 surrounding a hub ring 1. A spider wheel member 9 provides bearings 7, 8 for the spokes and is connected through torque blocks 17 to side plates 14, 15. An indented side plate 32 provides a location for a tyre inflating valve 36 and retains the tyre-retaining plate 29 and the inner rim 3 in position. The space 42 surrounding each spoke 6 is filled with lubricating-material and it is intended that except under overload (as shown), the outer flanges 10 of the spokes 6 shall not touch the outer rim 20, the whole of the weight being taken up by the pneumatic tyre 4.

Title: Improvements in apparatus for feeding tobacco to cigarette-making machines
Inventor: MORTIMER NOEL REGINALD FORTESC
IPC: A24C5/39
Filed: 1960-06-24
Abstract: 918,376. Pneumatic conveyers. VOKES Ltd. June 26, 1961 [June 24, 1960], No. 22302/60. Class 78 (1). In a pneumatic suction system for delivering tobacco from a single mechanical feeder 19, Fig. 3, to multiple dischargers 7-12 associated with utilizing machines 1-6, the tobacco is delivered to each of the dischargers 7-12, one at a time, according to the demand signalled by trip switches S A -S F  operated when the machines 1-6 are empty. The switches are sequentially connected to control circuits through a searching system, Fig. 1 (not shown), controlling the starting of the mechanical feeder 19 and the opening of valves 36-41 in one of the discharger suction lines 27-32. Tobacco is thereby fed into one of the dischargers 7-12 until it is full, at which moment the relevant one of a series of trip switches 53-58 is operated to stop the mechanical feeder 19 and reclose the associated valve 36-41. Removal of suction from a discharger permits the relevant exit flap 13-18 to fall open, releasing tobacco into the empty machine. A time delay circuit T, Fig. 1 (not shown) prevents re-connection of the dischargers with the suction line until sufficient time has been allowed for complete discharge. An air trip valve 35 operates to prevent the starting of the motor of the mechanical feeder 19 before the air velocity is sufficiently high. A thermal trip switch 142 (not shown) is also incorporated to prevent feed if the temperature in a discharger is too high.

Title: Improvements in or relating to a method of isolating protein from protein containing material
Inventor: TAYLOR HENRY
IPC: A23J1/14
Filed: 1951-09-26
Abstract: Vegetable globulins are precipitated from their aqueous alkaline solutions obtained by extraction from ground nut meal with a caustic soda solution having a concentration up to 0.1 per cent, by acidifying the solution to a pH of approximately 3.5 and thereafter adding caustic alkali to bring the mixture to the isoelectric point, a pH in the region of 5.  Preferably, small elements of streams of the aqueous alkaline solution of globulins and an acid precipitant to bring the resulting liquor to a pH of approximately 3.5 are progressively mixed under turbulence, the rate of delivery of acid precipitant being automatically controlled by the pH of the resulting stream of liquor containing precipitated globulin, and then small elements of this resulting stream are progressively mixed under turbulenece with so much caustic alkali solution that the resulting liquor attains the isoelectric pH value, the rate of delivery of caustic alkali solution being automatically controlled by the pH of the resulting alkali treated liquor containing the still undissolved precipitated vegetable globulin.  Suitable apparatus for such a process is described.  The acid precipitant is preferably 5 to 12 per cent hydrochloric acid containing an agent suppressing the action of bacteria and enzymes, e.g. sulphur dioxide. Specification 681,722 is referred to.

Title: Constant voltage transformer
IPC: G05F3/06
Filed: 1969-05-02
Abstract: 1,219,217. Transformers. VARO Inc. 2 May, 1969 [21 June, 1968], No. 22584/69. Heading H1T. A constant voltage transformer comprises a primary 11 (Fig. 1), secondary 13 and resonant winding 15 having a capacitor 16 across it, the core having a shunt member 20, 21 with a non-magnetic gap 22, and the core construction being such that the flux capacity of the core portion encircled by the primary 11 is greater than that of the core portion encircled by the secondary and resonant windings 13, 15 which latter is greater than the flux capacity of the shunt core member at the position at which its capacity is a minimum. Dimension A is preferably 20-60% greater than dimension B. The air gap 22 may be stepped or sloped in various ways (Figs. 2-7, not shown). An alternative core construction has the windings 11, 13, 15 (Fig. 8) on a stepped centre limb and separated by shunt members 42, 43 which may be of unequal lengths or different magnetic materials, e.g. of laminated, solid or sandwich construction. The gaps may be at either or both ends of the shunts. A number of variations of the core shape of Fig. 8 are described (Figs. 9-13, not shown). Where grain oriented core laminations are used the core is designed so that saturation occurs, e.g. in the core part surrounded by the windings 13, 15 before it occurs where the flux travels across the grain, e.g. in the I laminations adjacent the gaps 35. Alternatively, parts of the outer laminations or of the I laminations can be narrowed to secure initial saturation there (Fig. 9, not shown). In the E laminations width ¢D having a cross-grain flux may be about ¢(A+25%). Instead of having various widths of different core portions the different flux capacities may be secured by omitting some laminations, e.g. in the centre leg (Fig. 12, not shown), or by making different core portions of different materials. The output voltage of the transformer can be varied by varying the non-magnetic gap(s) 35 by varying the number of shims (of epoxy glass, mica or paper) in the gaps and then clamping. For use at higher frequencies the core may be of moulded construction (Fig. 13, not shown). The transformer may be provided with compensating windings.
