Patent GB-362458-A (GB)
Title: Improvements relating to the manufacture of condensation products of aldehydes and to catalysts for use in such manufacture
IPC: C07C29/14
Filed: 1930-09-04
Abstract: In the condensation of aldehydes to esters using an aluminium alcoholate as condensing agent, the reaction including the combination of aluminium and an alcohol to form the alcoholate is initiated in the presence of a preformed alcoholate free from halogeniferous or other auxiliary substances as catalyst, whilst excluding auxiliary substances such as halogen compounds from the reaction.  Advantageously butyl alcohol may be used for the preparation of the alcoholate.  The aluminium alcoholate, especially when using the butylate, may be employed for the condensation in the form of a suspension in excess of alcohol. When the aldehyde treated is acetaldehyde, and the alcoholate is employed suspended in butyl alcohol a partial conversion of the ethyl acetate formed into butyl acetate takes place.  In an example, sheet aluminium shavings are added to preformed aluminium butylate free from auxiliary substances, the crystal paste is heated to melting, butanol is added gradually while heating, and, after cooling and setting aside a portion of the butylate for the next operation, acetaldehyde is added gradually while stirring and cooling and the mixture allowed to stand for 12 hours, whereby a mixture of ethyl and butyl acetates, ethyl alcohol and unchanged butyl alcohol is obtained, and separated by distillation or other known means.

Title: Improvements in electro-magnetically actuated friction clutches and brakes
IPC: F16D27/08
Filed: 1945-10-10
Abstract: 599,540. Friction clutches. CLERK, R. C. Oct. 10, 1945, No. 26522. [Class 80(ii)] [Also in Group XXXIV] An electromagnetically applied friction brake or clutch includes, Fig. 2, an auxiliary brake comprising an annular electromagnet 32 which, when supplied with current through a switch 39 and slip rings 37, 38 is attracted into metal-to-metal frictional engagement with an annular armature 22 secured to a shaft 23. The resulting movement of the electromagnet 32 causes balls 34 in suitably shaped pockets 35, 36, in the electromagnet and in an annular friction disc 28 splined to the shaft 26 respectively, to force the disc 28 axially into frictional engagement with the armature 22 and to force the electromagnet 32 out of engagement with the armature, so frictionally coupling the shafts 26, 23. The movement of the electromagnet 32 is limited by a flange 25 on the shaft 26, and pull-off springs 31 are provided. The disc 28 has a facing 29 of moulded friction material. In another form of the invention, Fig. 1, the ball and shaped pocket coupling 34, 35, 36 between the electromagnet and the friction disc is replaced by a screwthreaded connection between the armature 19 and a friction disc 17 which forces the friction disc 17 into, and the armature 19 out of, engagement with the electromagnet 10 when the electromagnet and the armature come into frictional engagement. A ratchet 21 prevents operation of the screw coupling when braking the shaft 13 from movement opposite to the usual sense. This form of the invention operates as a means of automatically adjusting the brake or clutch for wear. In two other embodiments of the invention, one having a coupling as in Fig. 2 and one a coupling as in Fig. 1 between the electromagnet or the armature and the friction disc, one shaft in the case of a clutch, or the member to be braked in the case of a brake, has two armatures which enclose two friction discs and two electromagnets associated with the other shaft or with the fixed member, and are adapted to make frictional contact with these as in the constructions described. In both of the latter constructions a ball and shaped pocket connection between the annular friction discs and their associated shaft or fixed member provides a selfintensifying action.

Title: Improvements in or relating to the manufacture of alloys
IPC: C22C1/10
Filed: 1952-10-24
Abstract: Dense alloys are formed by mixing tungsten and/or molybdenum with a solution of a compound decomposable by heat to form refractory oxide and with a solution of a compound of a metal of lower melting point than, and limited solubility in, the main constituent, which compound is capable of being reduced to metal, heating the mixture in a reducing atmosphere to produce a dry mixture of powdered tuggsten and/or molybdenum, refractory oxide and the said metal, pressing the dry mixture to form a compact and sintering at a temperature above the melting point of the said metal.  The refractory oxide forms 1-20 per cent of the alloy and the lower melting point metal not more than 10 per cent.  The refractory oxide may be thorium oxide added as a solution of thorium nitrate and the lower melting metal may be nickel, e.g. in a proportion of 0.5-1 per cent, added as a solution of nickel chloride.  Reduction may be carried out at 500 DEG  C. in an atmosphere of town's gas, forming gas or hydrogen.  Other refractory oxides may be used, such as oxides of alkaline earth metals, aluminium, cerium, titanium, zirconium or silicon.  Other suitable lower melting point metals are cobalt, iron and platinum.

In a stereophonic pickup an elongate magnetic member carrying a stylus is embraced by four polepieces 40<SP>1</SP>, 41<SP>1</SP>, 42<SP>1</SP>, 43<SP>1</SP>(Fig 15), the spacings 74<SP>1</SP>, 75<SP>1</SP> between the adjacent lateral edges of the polepieces 40<SP>1</SP>, 42<SP>1</SP> and of the polepieces 41<SP>1</SP>, 43<SP>1</SP> being greater than the spacings 76<SP>1</SP>, 77<SP>1</SP> between the adjacent lateral edges of the polepieces 40<SP>1</SP>, 43<SP>1</SP> and of the polepieces 41<SP>1</SP>, 42<SP>1</SP>. Cross-talk is thereby reduced. In addition, the polepieces 40<SP>1</SP>, 41<SP>1</SP>, 42<SP>1</SP>, 43<SP>1</SP> may have the included angles at 76<SP>1</SP> and 77<SP>1</SP> greater than the included angles at 741 and 75<SP>1</SP>. The pick-up includes coils (25), (26) (Figs. 7, 10, not shown) for one channel and coils (27), (28) for the other channel. The coils of each pair are connected in series aiding relationship for the generated signals. The polepieces (40), (41) (Fig. 11, not shown) of one channel are opposite and parallel, as are the polepieces (42), (43) of the other channel. The polepieces flare outwardly and extend through the centres of the respective coils, forming cores (44), (45), (46), (47) (see Fig. 10). At the rear ends the cores (44), (45) are connected by members of magnetic material, as are cores (46), (47). Overlapping portions of the members are separated by non-magnetic material (50) (Fig. 12, not shown). The fixed parts of the pick-up, including the coils, polepieces, cores and terminals (32 ... 35) (see Fig. 7) are embedded in polystyrene or polyester (54), (55). The assembly is encased in a shielding casing (56). The ends of the polepieces are insulated from the casing (56) by a washer (57). A removable stylus assembly includes a non- magnetic tube (60) (see Fig. 7) connected to a plastics or resin handle (61). The moving system includes the stylus (62), an aluminium tube (64) and a permanent magnet (63) (Fig. 8, not shown). The tube (60) fits with the ends of the magnet (63) disposed between the polepieces (40-43). The tube (60) is a sliding fit with the washer (57). The forward end of the tube (60). flares outwardly and is embedded in the handle (61). A resilient bushing (65) (see Fig. 8) serves as a fulcrum for the magnet (63) and dampens oscillations. A tie wire (66) (see Fig. 8) extends between a slit (67) of the tube (60) and the tube (64). In use the coils, polepieces and moving system are at an angle to the record surface to minimize the mass of the moving system. Because of this the direction of movement of magnet (63) is along lines (72), (73) and crosstalk compensation is required. Reference has been directed by the Comptroller to Specifications 847,138, 897,323 and 943,873.
