Patent GB-1525061-A (GB)
Title: Clutch-brake combination
IPC: F16D27/112
Filed: 1976-02-25
Abstract: The spring-pressure clutch has three discs (6, 2, 7) on an output shaft (3). The disc facing the fixed brake magnet (1) is designed as a pressure disc (6) and is acted upon by a compression spring (8). On the side facing away from the electromagnet, there is arranged a clutch disc (7) and, between pressure disc (6) and clutch disc (7), there is arranged an armature disc (2). The discs (6, 2, 7) are mounted in axially displaceable fashion on the shaft (3) and the central armature disc also has the ability to rotate thereon. While the armature disc (2) immediately brakes solid on the braking magnet during the braking process (1), a relatively small braking torque comes into effect on the output shaft (3). This braking torque is made up, on the one hand, of a friction torque corresponding to the contact pressure between pressure disc (6) and armature disc (2) and, on the other hand, of a friction torque corresponding to the magnetic attraction between armature disc (2) and clutch disc (7). As a result, very low braking torques are possible with full clutch torques. <IMAGE>

Patent GB-719450-A (GB)
Title: A process for the preparation of unsaturated alicyclic 2-methyl butenal compounds
Filed: 1952-05-16
Abstract: The invention comprises compounds of the formula: <FORM:0719450/IV (b)/1> where one R is methyl and the others are methyl or hydrogen. These are made from <FORM:0719450/IV (b)/2> where R1 is alkyl by partial hydrogenation, dehydration and acid cleavage of the product (an enol ether or hemi-acetal, formul  being given).  The starting materials are made as in Specification 719,417.  In preferred operating conditions the hydrogenation is carried out using a palladium catalyst partially inactivated by lead and quinoline; the dehydration is effected with phosphorus oxychloride in toluene and pyridine, by passing the vapour over aluminium phosphate above 300 DEG  C. or by heating with an organic acid such as toluene-p-sulphonic in an inert solvent.  The last-named produces re-arrangement of the enol ether to a hemi-acetal and often effects cleavage to the aldehyde as well.  Otherwise a separate step, e.g. standing with aqueous alcoholic sulphuric acid, is necessary.  The products, which are intermediates in the synthesis of Vitamin A, may be purified by solvent extraction, distillation or chromatography. Examples show the production of 2-methyl-4-(21-methylcyclohexylidene) - buten - 2 - al and 2 - methyl-4 - (21 : 61 : 61 - trimethylcyclohexylidene)-buten-2-al.  They are characterized as 2 : 4-dinitrophenylhydrazones.

Title: Apparatus for the production of energy by nuclear fission
IPC: D01D1/09
Filed: 1940-04-29
Abstract: 614,156. Atomic piles. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, (formerly CAISSE NATIONALE DE LA RECHERCHE SCIENTIFIQUE). April 29, 1940, No. 7662. Convention date, May 1, 1939. [Class 39 (i)] An atomic pile comprises a homogeneous or heterogeneous distribution of deuterium (free or combined) or helium as a moderator in a mass of uranium or thorium, means for initiating a chain reaction by generating neutrons inside or outside the mass and means for removing the heat developed. The moderator may be in gaseous, liquid or solid (e.g. powder) form and the uranium may be present as uranium carbide. Thick diffusing layers, e.g. iron, lead, beryllium, calcium carbonate, surround the fissile mass and reflect neutrons which would otherwise escape, thereby reducing the critical size of the mass. This critical size is also reduced by increasing density, as by using compressed uranium powder. The reaction is initiated by cosmic radiation or by introducing a mixture of radium and beryllium. Stabilization is stated to be achieved by rising temperature and the reaction is stopped by separating two parts of the fissile mass or by increasing the quantity of the moderator. Liberated heat energy is removed by conduction, convection or radiation or by performing endothermal reactions within the pile. The moderator itself may be used for the removal of this heat energy. Emitted radiations may provide additional energy. Water screens protect the operators of the pile. By-products comprise radio-active or rare isotopes or mixtures of isotopes in anomalous proportions. The Specification refers to fast neutrons reacting with deuterium and beryllium within the pile, each neutron producing two slow neutrons.
