Title: Improvements in or relating to food concentrates
IPC: A23J3/30
Filed: 1959-01-28
Abstract: A food concentrate having the taste of meat broth is produced by making an aqueous extract from animal or vegetable protein, subjecting either the extraction residue or different proteinaceous material to an acid hydrolysis to yield a hydrolysate for which the ratio by weight between the total nitrogen content and the free amino nitrogen content is smaller than ten and greater than one, adding the hydrolysate to the aqueous extract and drying, or partially drying, the ingredients, either before or after mixing them, whereby a liquid, paste or powdered concentrate capable of being dissolved in or diluted with water is obtained.  In a modification, the extraction residue is subjected to a further water extraction in the presence of a proteolytic enzyme and the residue from this extraction is subjected to the acid hydrolysis.  The food concentrate may consist, for example, of 10-25% of the product derived from the aqueous extraction and 75-90% of the product of the acid hydrolysis.  The food concentrate may be employed in a wide variety of foods of which many are specified.  For the aqueous extraction there may, for example, be employed beef, whale meat or yeast and for the acid hydrolysis the yeast residue, or extracted soya beans or gluten. According to an example, 1 kg. chopped-up meat was heated for an hour in water at 90 DEG C.; the mixture was filtered, the residue was treated once more and the two extracts were combined (aqueous extract).  The residue from the second extraction was mixed with 800 c.c. water, the pH was adjusted to 7.5 and then the mixture was heated to 40 DEG  C.; 0.4 g. trypsin was added and allowed to act for about a quarter of an hour, after which the mixture was filtered (enzymatic extract).  The residue was mixed with 800 c.c. hydrochloric acid, heated up to 100 DEG  C., filtered and the filtrate was evaporated to dryness; the treatment was repeated with the residue until completely dissolved.  The products obtained from these successive acid hydrolyses were dissolved in 200 c.c. water and decolorized by treatment with active carbon (acid hydrolysate).  The aqueous extract, enzymatic extract and acid hydrolysate were mixed and spray-dried.

Abstract: 1,271,216. Locomotives. KLOCKNERHUMBOLDT-DEUTZ A.G. 23 Jan., 1970 [23 Jan., 1969], No. 3343/70. Headings B7H and B7L. A railway vehicle has at least one gas turbine engine 4 as a motive power unit, the or each engine being mounted on the roof of the vehicle and means being provided for transmitting the power output of the or each engine to the drive axles of the wheels of the vehicle. An hydraulic pump 17 is coupled to the turbine of engine 4, either directly or via a reduction gear unit, and transmits the engine output to the drive axles by oil pressure ducts housed in a hollow shaft 19 and hydraulic traction motors mounted on the wheel sets, the pump and traction motors together forming the transmission means. The turbine pump and an exhaust gas silencer 18 are housed in a casing 4a rotatable through 180 degrees about the shaft 18 so that an air inlet scoop 20 may be positioned to face in the direction of forward travel. In an alternative embodiment, Figs. 7-9, not shown, the engine (4) is coupled to a reduction gear unit (24). The power output of the gear unit (24) is transmitted via a bevel-gear transmission to a vertical, rotatable shaft (25) and then via an hydraulic clutch (26) and reduction- and reversing-gear unit (27) to the drive axles. In a further embodiment, Figs. 1-3, not shown, the turbine is coupled to a high-frequency electric generator (5) which together with electric traction motors forms the transmission means. In a vehicle or train of vehicles having more than one gas turbine engine the maximum capacity of the turbine of each engine is substantially equal to the maximum power output of the vehicle or train required divided by the number of engines per vehicle or train respectively.

Title: Improvements in or relating to turbines having overhung rotors
IPC: F01D9/02
Filed: 1943-03-01
Abstract: 571,658. Elastic-fluid turbines. BUCHI, A. March 1, 1943, No. 3352. Convention date, May 23, 1942. [Class 113 (iii)] The motive fluid, which may be hot gases, passes tangentially from inlet blades 6 into the blades 17 of an overhung rotor 1, and exhausts into a diffuser 22. Four, or two, fluid inlet pipes 4, are separated by spiral blades 15. Gas leaves the rotor and enters the diffuser at a pressure which is lower than the pressure at the exit end' of the diffuser. The rotor blades may be integral with the rotor, and thickened towards the hub. The diffuser hub 24 may be integral with the rotor and the diffuser may curve away at right angles to the rotor. To couple together the casing parts 4, 7, which, otherwise might move relatively due to unequal heat expansion, keys 27 are provided. Cooling of the blades is secured by vanes 28 on the back of the rotor, cooling air being drawn from a space 29 fed either by the atmosphere, or from a casing 9 supplied by a blower B. The vanes 28 have a disc 31. Holes 32 lead to the rotor blades 17 ; notches may also be provided in the rotor periphery or air may flow over the disc periphery. Sealing means 33, 34, may be incorporated, the space 35 in between communicating with the atmosphere, or the exhaust 23 through a pipe 36. In a modified arrangement, two inlet ports 4, only, are provided. The exit edges 20, of the blades 17, are cut off obliquely, and the innermost diameter of the diffuses is smaller than the extreme diameter of the outer exit edges 20. The hub of the rotor, tapering forward into the diffuser, is cooled internally. The exit angles of the blades at their inner and outer diameters, are designed so that the relative gas velocities (rotor peripheral speeds to absolute gas velocities) are substantially equal to each other, and to the absolute gas velocities. The flow into the inner edge of the diffuser is axial, and that at the outer edge produces a vortex, to convert velocity into pressure energy with the least loss.

IPC: H03K3/10
Filed: 1947-02-04
Abstract: 644,633. Pulse generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 4, 1947, No. 3358. [Class 40 (vi)] A circuit for producing pulses of constant width comprises a cross-coupled pair of valves 1 and 2 which act as a multivibrator, or a flipflop, according to their individual biasses, the cathode coupling including a delay line 6, which determines the pulse width. In operation, an input pulse (or a random disturbance) reduces the cathode current of valve 1 and hence the bias on blocked valve 2 which conducts until the pulse has been reflected at the open remote end of the line and has returned to the input, where it causes conductivity, to be transferred from valve 2 to valve 1. The circuit then remains in this state until another input pulse reduces the anode current of valve 1, or until the capacitor 13 forming the other coupling has discharged sufficiently to allow valve 2 to conduct, if the D.C. bias applied to the valve is low enough, this being the case when the circuit acts as a multivibrator. Capacitor 13 may be replaced by a direct coupling. In a modification, Fig. 2 (not shown), the delay line has its remote end shorted, and is connected between earth and the cathodes of the valves which are connected together. Specification 578,690 is referred to.

Filed: 1961-01-30
Abstract: 900,740. Making chains. DIAMOND CHAIN CO. Inc. Jan. 30, 1961, No. 3528/61. Class 83 (2). In a method of making a chain link plate 10 or 15 having holes for the reception of transverse bushes 11 or pins 16, the holes are enlarged to final size by means of a drift or ball 20 after the plate has been heat treated. The holes may also be enlarged prior to heat treatment. A hardened steel ball 20 is forced through the pitch holes of the link plate 10 by a punch 21. Instead of a ball 20 a hardened pin with tapered ends and a cylindrical mid-portion may be used. The plate is then heat treated and the drift again forced through the hole to relieve internal stresses and increase the density of the metal. If necessary, a slightly larger drift may be used for the second operation. The edges of the pitch hole are then chamfered by means of a shoulder 26 and fillet 27 on the punch 21.

Title: Improvements in or relating to apparatus for identifying or finding a marked or indicated circuit or wire
IPC: H04Q3/00
Filed: 1957-02-04
Abstract: 820,817. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 4, 1957 [Feb. 4, 1956], No. 3852/57. Class 40 (4). In a calling line identification system the calling condition of a line causes a pulse to be fed into a delay line at such a time and in such a position on the delay line as to produce therefrom an output pulse in a particular time position in one of a number of successive cycles of time positions, the output pulse being compared with cyclically recurring pulses in order to determine its time position and the cycle in which it occurs, the former characterizing part of the identity of the calling line, and the latter the rest of the identity. Pulse supply arrangements.-Pulses circulate in the two delay lines N1 and N3, having delay times of 1000Ás. (microseconds) and 100Ás., respectively, synchronizing pulses applied to the and-gates 01 and 02 at 100Ás. intervals serving to regenerate the pulse in each of these delay Ines. The ten take-off coils M0 to M9 of line N1, are spaced at 100Ás. intervals whereas those (M10 to M19) of line N3 are at 10Ás. intervals. Thus the appearance of a pulse at one of the coils M10 to M19 defines one of ten time positions in a cycle of length 100Ás., whereas the appearance of a pulse at each of the take-off coils M0 to M9 defines the commencement of each of ten successive cycles. Operation.-When a pulse arrives at one of the take-off coils M0 to M9, say M9, it is amplified as at G9 and is applied via bus H9 to one input of each of ten and-gates, each associated with one of the ten lines having the tens digit " 9." For those lines which are not calling, e.g. line "90," the relevant K contacts connect negative potential to the resistance R of the gate and the pulse on H9 is without effect. If, however, a line, say " 99," is in the calling condition, its K contact is operated and connects positive potential to the corresponding resistance R; the and-gate passes the pulse on H9 to the vertical lens V9, it is amplified by F9 and applied to the transmitting coil S9 on delay line N2. The coils S0 to S9 are spaced 10Ás. apart and d4 is equal to 100Ás. delay so that for a line of which the number is mn, a pulse arrives at the take-off coil M20 at an instant (m+2)100 plus (9 - n)10 microseconds after leaving the transmitting coil T1. Coincidence of this pulse with one from the relevant take-off coil of M10 to M19 opens the corresponding and-gate, say 03, and the bi-stable device B9, indicative of the units digit, is operated. Coincidence of the output pulse of this device with the pulse from the next coil of M0 to M9 opens the and-gate, say 09, relevant to the tens digit and operates the device, B19, to register this digit. In order to prevent the identification of more than one line at a time, it is arranged that the output from the take-off coil M20 is inhibited by the operation of any one of the bi-stable devices B0 to B9. Rectifier-resistor and rectifiercapacity and-gates are described.
