Patent GB-447159-A (GB)
Title: A method of effecting continuous hydrogenation and other catalytic reactions
IPC: B01J19/20
Filed: 1935-04-08
Abstract: <PICT:0447159/III/1> In catalytic reactions such as the hydrogenation or reduction of liquid organic compounds e.g. oils, nitrobenzene, in which a powdered catalyst is employed in a suspended state, high tension alternating current is applied during the reaction to promote agitation of the materials, and after the reaction, high tension direct current is applied to effect separation and retention of the catalyst in the reaction chamber, whereby successive batches of materials are readily treated.  In the arrangement shown, the reaction vessel 2 is surrounded by a heating device 1 and serves as one electrode which is earthed.  The insulator 4 carrying a central electrode 3 which may be covered with insulating material, is arranged to end below the surface of the liquid.  Hydrogen is introduced through inlet 6 and a stirrer 7 arranged to assist the electrical agitation.  After the reaction, high tension direct current is applied to the electrodes by means of switch 10 and rectifier 12, electrode 3 functioning as an anode.  The catalyst, e.g. nickel, is deposited on the walls of vessel 2, and the reaction product removed through outlet 9 by the introduction of fresh material by the inlet 5.  The fresh material is then treated with the application of alternating current.  According to examples: (1) soya bean oil is mixed with 5 per cent of NiO, heated to 200 DEG  C., and hydrogen introduced at the rate of 100 c.c. per minute.  An alternating voltage of 18000 was applied during the reaction, and after the reaction 18000 volts direct current was applied to effect separation of the catalyst; (2) Nitrobenzene was reduced to aniline by treatment for five hours, using 1 per cent of nickel as catalyst and applying 18000 volts alternating current to the electrodes. Separation of the catalyst was effected by the application of direct current.

Title: Improvements in or relating to artificial horsehair for upholstery stuffing material, brush material, bristle material and the like
IPC: D01C3/00
Filed: 1936-04-16
Abstract: Artificial horsehair, bristles, &c. are obtained by converting hide, leather, &c. into a highly swollen paste still containing the natural fibres of the starting material, and then extruding the paste under high pressure through nozzles of 0,5--1,0 mm. diameter, the extruded threads being dried and if desired treated with tanning and water-extracting agents.  For this latter purpose baths of common salt, bicarbonate or ammonium chloride, or tanning baths containing a high proportion of common salt or sodium sulphate may be used; after subsequent drying, the threads may be tanned as by zirconium or chromium compounds.  To prepare the fibrous paste, the material may be first limed and then treated with hydrochloric acid, or heated with water until the desired swollen condition is attained, and the starting material may first be subjected to a partial hydrolytic decomposition; before use, the swollen product may be mechanically treated as by kneading or mixing, and it may be dehydrated as by treatment with glycerine &c.  The nozzles used for the extrusion are preferably long and of gradual taper.  Softeners such as castor, paraffin and train oils may be introduced into the water-swollen threads preferably after dehydration by acetone, alcohol, &c., and into the hardened threads after treatment with organic swelling agents such as glycerine.  The threads may be coloured and curled. In examples, pastes made from hide wastes, leather parings, &c. after liming and treating with hydrochloric acid, are extruded, and the threads are dried and thereafter passed into a sodium sulphate bath followed by a basic chromium sulphate bath, or into a sodium bicarbonate bath followed by a zirconium chloride-sodium sulphate bath.  Specifications 422,990, [Group IX], and 429,039 are referred to.  The Specification as open to inspection under Sect. 91 refers to the threads being passed without drying into the water-extracting or tanning baths, and instances alcohol as a suitable coagulating medium; and it also mentions that meats, flesh, sinews, &c. may be used as the basis of the paste.  This subject-matter does not appear in the Specification as accepted.

Title: Acceleration and retardation control arrangement for electric motor-driven vehicles
IPC: B60L3/00
Filed: 1948-04-26
Abstract: 641,763. Controllers. SVENSKA AKTIEBOLAGET BROMSREGULATOR. April 26, 1948, No. 11430. Convention date, May 5, 1947. [Class 38(iii)] A device for automatically controlling the acceleration of electric motor-driven vehicles on starting comprises a brake adapter of the kind in which the braking- power is controlled in dependence on the vehicle-load by means of a control spring operated by a force derived from and varying with said load, and means for controlling the torque of the driving- motors which is also operated by the same control spring. Braking mechanism for a vehicle comprises a spring 3 which is deflected in accordance with the vehicle-load so as to determine the ratio between the force exerted by the brake cylinder and that transmitted to the brake shoes. A pin 11 on an arm 10, which is pivotally mounted at 9, is pressed into engagement with the spring 3, one end of the arm being formed as a contact 13 co-operating with studs 14 in the driving-motor circuit. The arm 10 occupies different positions with different vehicle loads, so adjusting the driving- torque in accordance with the vehicleloading. In a modification, Fig. 3, (not shown), a single shaft mounts a resilient arm co-operating with the control spring 3. This arm is pressed against the spring 3 by another arm on the shaft which is coupled to a spring within a fluid-containing cylinder. Movements of the shaft, which also carries the contact-arm, are therefore damped. In a further modification, Fig. 6, (not shown), the shaft is locked in the position in which it is set by the spring 3 by means of a solenoid which is energized when the vehicle is started. The solenoid may be replaced by a compressed air cylinder. The contact device may be arranged to afford a linear relation between the vehicle load and the adjusted torque. Specifications 565,517, 578,174 and 639,486, [all in Group XXXIV], are referred to.

The coils 13, 16 may be in series or in parallel.

[Class 78 (i)] [Also in Group XII] Air and fuel are fed to a furnace through a single conveyer conduit 26, the air being supplied by a blower 9 to the conduit at a point intermediate the source of fuel 25 and the furnace 1. The conveyer 28 has a greater capacity adjacent the furnace than at the part 32 adjacent the source of fuel so that the part of the conduit adjacent the furnace is only partly filled with fuel. Space is also left between the conveyer and the top of the conduit for the passage of air. At the point 30 some of the turns of the conveyer thread may be omitted to provide a resistance to back flow of air towards the fuel source. Any air or gas flowing back to the source of fuel may be withdrawn by a conduit 33 leading to the atmosphere or to the inlet of the blower. The air supply to the blower is controlled by a valve and a branch from the conveyer conduit leads air to the chamber 4 beneath the grate. At the point 30 the threads of the conveyer may be of smaller diameter or have a greater capacity or pitch than at the point 31.

[Class 40 (iv)] An auxiliary circuit such as a monitoring circuit or a branch of a distribution system is coupled to a main transmission line by means of a transformer associated with a resistance (which may be the resistance of the secondary winding) in such a way that the impedance, looking back into the transformer &c., is equal to that of the input of the auxiliary circuit itself, or when a narrow band of frequencies is concerned, by means of a substantially self-terminated band pass filter, i.e., one in which the dissipative part of the impedance of the end arm (series or shunt) is equal to the derative impedance at that end at the mid-band frequency. In this case the impedance of the auxiliary circuit is adjusted so that the impedance looking back from the auxiliary circuit to the main circuit equals the impedance-of the auxiliary circuit if the resistive parts of the impedances of the arms nearest the main and auxiliary circuits respectively are regarded as belonging to such circuits and not to the filter. The Specification shows how to calculate the values of the resistance in the case of a filter of " constant k " type.
