Abstract: 492,182. Portable huts ; ventilating ; heat-controlling. NEWCON INDUSTRIES, Ltd., CROWDEN, G. P., and ADAMS, C. H. March 15, 1937, Nos. 7592 and 30767. [Classes 20 (i) and 137] [Also in Group XIII] In order to avoid extremes of temperature within a cabinet or building, the walls and roof are formed of three separated layers, one or all of which are metal faced, forming double air spaces, and conditioned air is supplied to the cabinet and passes through apertures in the wall to the inner wall space, thence to the inner roof space and out through apertures in the outer layer. Air is supplied through the conditioner 18 to the interior, and apertures 50 are provided in the lower portions of the walls through which the air passes to the inner wall spaces, through communicating apertures 52, Fig. 2, to the inner roof space and thence through aperture 56, 58 to the outer air. The walls and roof are formed of juxtaposed panels, each provided with sealing edge strips 48, Fig. 4, and the panels are joined by toggle levers 60. Each panel comprises E-shaped frame bars, outer layers 42 of laminated paper impregnated with artificial resin, and a middle layer 44 faced on both sides with aluminium foil. The external layers of the panels may be plywood impregnated with resin or sheet material having an asbestos basis to render the building non- inflammable. The floor panels are constructed of cork faced with linoleum and are assembled with overlapping joints at the edges of their metal frames. In an alternative construction, the panel-frame members are formed of two channel-section bars secured together by adjacent flanges with the middle layer between them, and the securing bolts passing through the flanges of the bars are insulated from the central layer.

Abstract: 214,061. Cooksley, A. March 16, 1923. Mortising.-Guards for chain-mortising machines comprise a guard plate 14 pivoted upon a vertical rod 11 supported upon the splinter pad attachment 5 of the machine. The plate 14 comes in front of the cutting chain 2, which rises and falls with a sliding head 1 operated by a handlever 3. An arm 10 extending from the pad 5 supports the rod 11, which in turn carries a collar 12 upon which the guard-plate hinge 13 rests, so that the plate 14 rises with the pad 5. The plate 14 is normally locked in the operative position shown in Fig. 1 by a tooth 15 depending from the hinge 13 engaging a recess 16 in the collar 12. The guard plate is opened like a door into the position of Fig. 4 by first raising it by hand to free the tooth 15. The pad 5 is pressed down by the weight S and a rod 19 limits the descent of the tool.

Abstract: 847,705. Semiconductor devices. SHOCKLEY TRANSISTOR CORPORATION. March 11, 1958 [March 18, 1957], No. 7876/58. Class 37 A semiconductor device comprises a semiconductor body of one conductivity type having a grain boundary along which extends a diffusion produced zone of opposite conductivity type Fig. 1A shows a P-type silicon crystal having a grain boundary 12 produced by growing the crystal from a pair of seed crystals and tilting the crystal lattice 15 produce a bi-crystal with edge dislocations. Donor material is diffused into the surface to produce a layer of N-type material with deeper penetration along the grade boundary as shown in Fig. 1B. A second dispersion treatment utilising a high density of acceptors is then applied so that an outer P-layer is formed which cuts through the N-layer along the grain boundary as shown in Fig. 1C. A masking, etching and cutting treatment is employed to form two junction transistors as shown in Fig. ID, the upper and lower P-layer constituting the bases, and the two N-type regions in each case, the emitter and collector electrodes. The structure may also be used as a field effect transistor, the upper and lower P-type regions constituting the source and drain respectively in each case, and the N-type regions the gates. A modification is described, to provide a field effect transistor with, low drain-gate capacity, in which the first diffusion is applied in two stages to provide first an N- and then an N + region. Fig. 3 shows an alternative arrangement in which an N-type crystal with grain boundary 11 us subjected to diffusion by acceptors and then etched to produce the junction transistor structure shown in Fig. 3C in which the emitter and collector are constituted by the N-type regions on either side of the grain boundary P-type zone.

Title: Improvements in and relating to automatic machines for assembling in the form of panels, laths and similar elements and the panels resulting therefrom
IPC: B27M3/00
Filed: 1954-03-18
Abstract: <PICT:0746135/III/1> In a machine for gluing laths together to form panels, one side of laths fed by rollers 117, 119 is coated with glue by a slightly-crowned roller 154 supplied with adhesive from the arcuate opening 157 of a duct 158 adjustably connected to a reservoir 159 by a screw 160.  The laths pass between a pivotallymounted blade 137 and rollers 139 which normally press them against the gluing roller but, after a predetermined number of laths have been counted by means such as a chain 148, dog 147 and switch I2, the blade 137 and rollers 139 are pivoted by a solenoid 145 to withdraw one lath from the gluing roller, in order to determine the beginning of a new panel.  A short length of this lath, extending tangentially beyond the circumference of the gluing roller, has already had adhesive applied and this serves to connect adjacent completed panels in a readily-detachable manner.

Title: Novel esters and a process for the manufacture thereof
Filed: 1954-07-07
Abstract: The invention comprises alkyl esters of 4-methyl - 6 - [21.61.61 - trimethyl-cyclohexen-(11)-yl] - hexadien - (2.4) - oic(1) acid in which the alkyl groups contain from 1 to 4 carbon atoms. They may be prepared by condensing 2-methyl-4 - [21.61.61 - trimethyl - cyclohexene - (11) - yl] buten - (2) - al(1) with a halogeno - acetic acid lower-alkyl ester and dehydrating the resulting 2.3 - epoxy - trimethyl - 6 - [21.61.61 - trimethylcyclohexen - (11) - yl] - hexen - (4) - oic(1) acid ester or 3 - hydroxy - 4 - methyl - 6 - [21.6.61-trimethylcyclohexen - (11) - yl] - hexen - (4) - oic(1) acid ester by heating in a solvent in the presence of an acidic dehydrating agent.  The condensation step is carried out in known manner by using a metal, e.g. zinc or sodium, or an alkali-metal alcoholate, e.g. sodium methylate, as condensing agent.  Preferably the condensation is carried out as a Reformatsky reaction using a bromo-acetic acid lower-alkyl ester.  The product is a hydroxy ester. Alternatively the condensation may be carried out using a chloroacetic acid ester and sodium methylate in which case the product is an epoxy ester. The latter may be converted by heat into the corresponding keto-acid ester which may be reduced to the hydroxy ester.  The dehydration of the hydroxy ester or the epoxy ester may be carried out by heating the ester in a solvent such as toluene or xylene in the presence of an acidic dehydrating agent such as p-toluene-sulphonic acid.  In the example (a) a mixture of 2-methyl-4 - [21.61.61 - trimethyl - cyclohexene - (1)1 - yl]-buten - (2) - al - (1), bromo - acetic acid ethyl ester and ether are added to zinc to give 3-hydroxy - 4 - methyl - 6 - [21.61.61 - trimethyl-cyclohexen - (11) - yl] - hexen - (4) - oic - (1) - acid ethyl ester which is heated in toluene solution with p-toluene sulphonic acid to give 4-methyl-6 - [21.61.61 - trimethyl - cyclohexen - (11) - yl]-hexadien-(2.4)-oic-(1) acid ethyl ester.
