Patent GB-658477-A (GB)
Title: A process for preparing moulded catalyst masses of great mechanical strength
IPC: B01J37/02
Filed: 1949-10-25
Abstract: Catalysts of high mechanical strength are obtained by impregnating a carrier with a solution of a metal compound decomposable by heat to the oxide, heating to produce the oxide, reimpregnating the material with a further solution of the metal compound, drying, compressing into pellets and then heating to form the oxide.  An example describes the preparation of a nickel oxide-chromium oxide on alumina catalyst from nickel and chromium nitrate solutions.  Other specified active component metals are iron, cobalt, copper, manganese, and molybdenum.  The catalysts may be employed for hydrogenating and refining oils, the hydrogenation of aldehydes to alcohols, of esters to alcohols and the hydrogenating purification of alcohols.

Title: Improvements in or relating to high velocity liquid jets
Inventor: FRANZ NORMAN CHARLES
IPC: B24C1/00
Filed: 1969-05-30
Abstract: 1,242,929. Liquid jet cutting. N. C. FRANZ. 30 May, 1969 [31 May, 1968], No. 27500/69. Heading B5L. [Also in Division B3] The penetration into a workpiece surface of a high velocity liquid jet, e.g. for cutting wood, is increased by dissolving a long chain polymer in the working liquid, so that the viscosity of the liquid at low shear rates is raised to render the jet more cohesive. Solid particles, e.g. glass beads, may be added to the working liquid, which is generally water containing e.g. dissolved polyalkylene oxides, gelatin or methylcellulose polymers, and the polymer may be dissolved in a water-miscible solvent such as a lower alkanol, prior to mixing with the water.

Abstract: 652,510. Making gilled tubes. BENNETT, F. M., and WEAVER, C. J. Oct. 22, 1948, No. 27541. [Classes 83 (ii) and 83 (iv)] Tube expanders.-In apparatus for making gilled tubes discs strung on a tube in spaced relation are moved over a stationary expanding tool to effect pointing. An electromotor 19 drives a chain 55 with clamping carriage 73 to which a tube T is secured. Loose fins 83 strung on the tube are spaced by opposed helicallygrooved rolls 45 rotated by the electromotor 19. A removable expanding head on a fixed mandrel 63 is positioned within the tube. As the tube and the fins are pulled over the head the tube is expanded to secure the fins. The chain 55 is driven at constant speed and the speed of the rolls 45 is varied by changing gears 31, 32 in the driving-chain.

IPC: C13B35/08
Filed: 1949-10-28
Abstract: A dialysis membrane in which is incorporated 1/2 to 35 per cent of a finely-divided decolorizing agent such as active charcoal is formed of a hydrophilic organic material such as cellulose hydrate, alkyl, hydroxy-alkyl and carboxy-alkyl or mixed cellulose ethers, cellulose esters such as low nitrated cellulose nitrate, low esterified cellulose acetate or formate, gelatine, casein, de-acetylated chitin or water-swelling resins such as water-swelling polymers of acrylic acid, methyl-methacrylates or polyvinyl alcohol.  Denitrated nitro-cellulose is preferred, and the materials after incorporation of the decolorizing agent are formed, for example, by extrusion, into foil, films, sheets, bags or tubes, which may then be coagulated, cured or indurated.

Cellulosic membranes may be modified by precipitation at one or both surfaces or at an intermediate plane of melamine-formaldehyde, urea-formaldehyde or other resin, preferably by impregnating one or both surfaces with a water-soluble preliminary condensate and polymerizing in situ to form a water insoluble deposit within the membrane as described in Specification 655,663.  Specification 262,131, [Class 1 (i)], also is referred to.ALSO:A dialysis membrane comprises a pellicle of a hydrophilic oragnic material in which is incorporated between one-half and 35 per cent by weight, and preferably 8-15 per cent of a finely divided decolorizing agent such as activated carbon.  Suitable organic materials are cellulose, gelatin, casein, de-acetylated chitin and water swelling resins such as polymers of acrylic acid, methyl methacrylate, polyvinyl alcohol resins, denitrated nitrocellulose being preferred.  Cellulose pellicles may be modified by precipitation on the surface or at some intermediate plane of a water soluble resin such as melamine formaldehyde or urea formaldehyde.  Inorganic salts such as copper ferrocyanide may be incorporated in the finished pellicle which may be formed in sheets, bags or tubes.

Title: Improvements in or relating to motor driven vehicles
Filed: 1936-11-13
Abstract: 483,214. Controlling motor vehicles. GUY, S. S., and AVERNS, R. DEAN-. Nov. 13, 1936, No. 27778/37. Divided out of 478,614. [Class 79 (v)] In a motor vehicle provided with an electric generator driven by the vehicle engine for purposes extraneous to the vehicle propulsion such as a searchlight, means are provided whereby the vehicle change - speed gear is rendered inoperative when the generator circuit is completed, and vice versa. In the construction shown the armature shaft 2 of the generator connects the engine 3 to the clutch 6 and change-speed gear so that the shaft 2 always rotates with the engine shaft. The change-speed gear is controlled by a gearlever 44 through a control shaft 32. The generator circuit is controlled by a switch 8 operated by a hand-lever 27 through a hollow shaft 35, arm 28 and link 29, the hand-lever having two positions determined by a quadrant 33. A second arm 30 on the shaft 35 rocks a locking plate 31 adapted, when in operative position, to prevent axial movement of the gear control shaft 32 from the neutral position. When the generator is to be used the vehicle is stopped, the gear-lever is placed in the neutral position, and the hand-lever 27 is moved to its second position to lock the gear control shaft 32 and close the switch 8. At the same time the engine throttle 13 is adjusted to provide a suitable engine speed when the generator is not under load. For this purpose a shaft 34, normally rotating with the shaft 35, carries an arm 36 forming an adjustable stop for a lever 16 connected to the throttle and the accelerator pedal 25, this stop determining the slow running position. The shaft 34 has a second arm 37 connected by an adjustable link 39 to a lever 38 mounted on the hand-lever 27 and bearing against a stop 41 which can be adjusted to regulate the running speed of the engine under " noload " conditions. When the generator is in use the engine speed is automatically controlled by a solenoid governor the circuit of which is completed simultaneously with the closing of the main switch 8.

Fig. 1a shows an 8-place binary code obtained by a coding device CS, Fig. 3, using a code in a programme store CP whereby HF pulses generated in a transmitter oscillator SO are phase modulated as shown in Fig. 1b. In Fig. 4 the device CS is replaced by two HF transmitters SO1, SO2 operating at frequencies fl, f2 and keyed by the store CP. In Fig. 2 the received echo signals pass to the delay line V through a mixer stage EM and the limiter stage EB. In Fig. 4 the stage EB is followed by two lines L1, L2, containing bandpass filters F 1, F2 tuned respectively to fl, f2. G1, G2 are rectifiers, UST is an inverter stage and ZE is a combiner. The stage EB drastically clips the received signal at a level R which is the inherent noise level of the receiver. The threshold device EP is set at a higher level e.g. five times R.

Abstract: 1310953 Rolling mills GENERAL ELECTRIC CO 12 June 1970 [27 June 1969] 28445/70 Heading B3M The rolls of a rolling mill are set to roll a workpiece to a desired thickness, the roll setting being computed according to a material hardness factor (M.H.F.) appropriate to the workpiece, and to the mill stretch. The value of M.H.F. is derived from a family of curves stored in a computer, each curve plotting M.H.F. against workpiece width for different values of resistance to deformation of the workpiece. Similarly, the value of mill stretch at the anticipated force level is derived from a family of curves representing mill stretch against roll separating force for different workpiece widths. The M.H.F. is related to the resistance to deformation and is used to modify the value of mill stretch when setting the mill; the mill stretch value is multiplied by a factor K1 + K2 (M.H.F.- 1-0) to provide a final roll setting, where K1 and K2 are predetermined constants.
