Title: Improvements in radio communication systems
IPC: H04B1/54
Filed: 1939-07-05
Abstract: 531,554. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and SPAGNOLETTI, P. H. July 5, 1939, No. 19566. [Class 40 (v)] A radio telegraphic system is provided with automatic means under the control of the keying device for interrupting the operation of the master oscillator at the transmitter when the keying device remains unoperated for a predetermined time. The key C operates a relay A having a pair of contacts a<SP>1</SP> which when closed connect H.T.+ via conductor K to the keyed stage of the transmitter not shown. A second pair of contacts a<SP>2</SP> when closed cause energization of relay B to close contacts b<SP>1</SP> thus connecting suitable bias from H.T. over conductor O to the master oscillator not shown. Relay B also controls change-over contacts b<SP>2</SP> for connecting the aerial lead AN to the transmitter lead T or receiver lead R. Relay B is made slow to release such as by a slug S. Thus during normal transmission contacts b<SP>1</SP>, b<SP>2</SP> remain in a position to energize the oscillator and to connect the aerial for transmission. If however key C remains open for a given time, relay B drops off to render the oscillator inoperative and connect the aerial for reception.

Title: Improvements relating to yeast or protein preparations
IPC: A23J3/34
Filed: 1936-07-16
Abstract: Vegetable protein materials containing at least 25 per cent of substantially undegraded protein which is substantially insoluble in water, e.g. soya meal, brewers' grains, and ground peanut cake, or casein are subjected preferably in a closed vessel to an aqueous treatment at temperatures sufficiently high to render soluble a substantial proportion, e.g. 60 per cent and over, of the protein in a few, e.g. 2--3 hours, the product being treated, if desired, after removing the fraction still insoluble as by centrifuging, with active yeast autolysate to degrade the proteins and give a food or medicinal product.  The predigestion may be effected by heating the protein material at 100--135 DEG  C. at atmospheric or higher pressure and the aqueous medium used may be acidified, preferably with phosphoric or other acid without action on the cellulosic constituents of the material; the acid used may be capable of reacting with a base, e.g. sodium carbonate, to form buffer substances for controlling the pH in the subsequent proteolysis.  The predigestion may effect a partial degradation of the protein to amino acid.ALSO:Products rich in degraded proteins, for food or medicinal purposes, are prepared from vegetable protein materials containing at least about 25 per cent of substantially undegraded protein which is substantially insoluble in cold water, e.g. soya meal, brewers' grains and ground peanut press-cake, and from casein, by subjecting the materials, preferably in a closed vessel, to an aqueous treatment at temperatures sufficiently high to render soluble a substantial proportion, e.g. 60 per cent and over, of the protein in a few, e.g. 2-3, hours, the product, from which the fraction still insoluble may be removed, as by centrifuging, being mixed with active yeast autolysate for protein degradation. The predigestion may be effected by heating the protein material at about 100-135 DEG  C. at atmospheric or higher pressure and the aqueous medium used may be acidified, preferably with phosphoric or other acid without action on the cellulosic constituents of the material; the acid used may be capable of reacting with a base, e.g. sodium carbonate, to form buffer substances for controlling the pH in the subsequent proteolysis.  The predigestion may also effect a partial degradation of the protein to amino acid; it may be carried out with the material in dough-like form, and the treated material may be brought by heating, e.g. for about 2 hrs. in an oven at 120 DEG  C., to dryness or semi-dryness before the yeast autolysate is added.  The yeast autolysate may be prepared and may be used for the proteolysis as set forth in Specification 450,529.  Examples of the treatment of soya meal and ground nut meal are given.

Abstract: 1314991 Fluidic circuits PNEUMOTECH AG 24 April 1970 [24 April 1969] 19865/70 Heading G4P [Also in Division F2] A fluidic digital control device defines first and second paths for a fluid to flow through, and includes a fluid flow switching device for controlling the fluid flow along said paths; said switching device comprising a valve assembly comprising at least two valves and a rigid member supporting said valves and movable between a stable and a labile operative position, and a control element for moving said rigid member from said stable to said labile position in response to a control signal; the switching devic e allowing the fluid to flow either along said first path when the rigid member is in its stable position, or along said second path when the rigid member is in its labile position without overlap affects during the switching period. Fig. 1, AND gate. In the OFF position a supply fluid from duct 11 inflates a moulded flexible bellows 32 which moves hollow piston 23 leftwards and forces seal 35 against fixed member 7, hence no fluid passes to output 13 which is connected to atmosphere 9 via hollow piston 23. When a control fluid pressure at 39 is provided, bellows 17 expand rightwards and engage with the tube 24 sealing it from the atmosphere 9. Then the bellows 17 push the tube 22 rightwards thus unsealing 37 and 7 and allowing the supply from duct 11 to pass to output 13. This device can also give pressure amplication owing to the different bellows areas used. The circuit may be partly made in integrated form using machining or photo-etching. The device can be modified to form an inverter to produce a "snap action" switching, to produce a mechanical output to or to produce a combined AND gate and invertor (Figs. 2 to 6, not shown). Fig. 7, AND gate.-This comprises a two part housing 165, 166. An input to rolling bellows 171 through bore 183 causes the bellows to contact tube 188 and cut off the output 193 from atmosphere 181. Next the seal 190 is moved from surface 192 and the supply passes from chamber 194 to output 193. The supply and output pass through hollow mounting screws 168, 169. The device may be modified by addition of a leaf spring (Fig. 8, not shown) and the AND gate of Fig. 7 can be modified to form a negator (Figs. 9 and 10, not shown).

Title: Improvements in or relating to axial flow fans
IPC: F04D29/34
Filed: 1955-07-11
Abstract: 816,921. Axial-flow fans. AIR CONTROL INSTALLATIONS Ltd., and REEVES, H. C. Oct. 11, 1956 [July 11, 1955], No. 20047/55. Class 110(1). To reduce blade flutter in an axial-flow fan, each blade is formed either in one part or in two parts arranged end-to-end, and a pivotal connection is provided either between the inner extremity of each one-part blade and the hub or between an outer part of each two-part blade and an inner part secured to the hub so that the axis of pivotal movement extends across the width of the blade substantially parallel to the general plane thereof or to a chord of the blade section; and the pivotal connection between the hub and each one-part blade or between the two parts of a two-part blade or the connection between the hub and the inner part of each twopart blade is rotatably adjustable about an axis radially disposed with respect to the axis of rotation of the fan, clamping means being provided for maintaining the adjustment. In the three-bladed fan shown, each blade 10 is of curved or aerofoil cross-section and formed from sheet metal riveted at 28 to a cast steel shoe 25 having two bosses 26 by which it is pivoted about a pin 23 carried by a block 17, the pivotal axis being substantially parallel to the general plane of the blade or to a chord of the blade section at the locality of the pivotal connection. The block 17 can be turned to adjust the blade angle after loosening the nut 18 which fixes it to the impeller hub 11. Each boss 26 is attached to the pivot-pin 23 by means of a rubber bush 31 bonded to outer and inner sleeves 29, 30 fixed to the boss and pin respectively, so that pivotal movement is torsionally resisted. Alternatively, conventional lubricated bushes may be used, providing free pivotal movement. The shoe 25 carries a part-circular sleeve 32 which limits the pivotal movement relative to the block 17. In an alternative construction, the pivot is provided between a radially inner part and a radially outer part of the blade. For this purpose, the inner end of the outer blade part is riveted to a shoe 25, and a block corresponding to the block 17 is carried by a further shoe riveted to the outer end of the inner blade part. The block may be adjustably secured to the further shoe or integral with it. In the former case, the adjustable connection between the inner blade part and the impeller hub may be replaced by a fixed connection. The inner blade part may depart from true aerofoil form for strength purposes.
