Title: Improvements in and relating to the ventilation of vehicles
IPC: B60H1/26
Filed: 1929-03-11
Abstract: 330,878. Wise, C., and Dumbleton, G. H. March 11, 1929. No Patent granted (Sealing fee not paid). Bodies.-In a ventilating system for motor vehicles of the type in which longitudinally extending air ducts are formed in the roof of the vehicle and are connected with the interior thereof by controlled apertures through which, during movement of the vehicle, air may be introduced into and extracted from the interior of the vehicle, the cross members which support the roof covering are formed with apertures between adjacent roof longitudinals and the space or spaces between the longitudinals enclosed to form one or more ducts for the ventilation of the vehicle. A funnel-like member 1, Fig. 1, is arranged in the front of the canopy 2 so that when the vehicle is in motion air is both forced and sucked into this funnel; baffle plates 4 and gauze covering the inlet serve to retain moisture &c. The air passes into one or more ducts 11, which are formed in the spaces between pairs of roof longitudinals 8 by constructing the cross members with holes 10 and attaching waterproof material 12 to the inner side of the longitudinals. When a regulator 18 is open part of the air is deflected by a plate 24 to pass into the vehicle. The regulator comprises a fixed member 20 having a number of holes therein, and a movable member 22 with a corresponding number of similar holes. The other portion of the air passes to the rear of the vehicle and over a plate 27 where, when a regulartor 26 is open, this current of air causes a flow of air from the interior of the vehicle. Discharge occurs at the outlet 14. In the case of a vehicle with a sliding roof in which the movable portion 29, Fig. 3, of the roof slides under the rear fixed portion 28, the inlet of the duct 11 is formed by a hinged flap 30 controlled e.g. by a Bowden wire. When. the movable portion of the roof slides over the rear fixed portion, the forward end of the air duct may open into the forward end of the fixed portion of the roof. When the roof is opened by movable portions which slide laterally, the front end of the duct may be formed partly in each of the movable portions of the roof along their abutting edges. In all the above cases the opening at the front end of the duct may be dispensed with and the regulators arranged so that the partial vacuum at the rear of the vehicle when the vehicle is in motion is utilized to extract air from the interior thereof. Also separate ducts may be used for the supply of air to the interior of the vehicle and the extraction of air therefrom. The first Provisional Specification states that the walls of the duct may be formed of timber or metal and separate from the roof of the vehicle, and also that the invention may be applied to vehicles other than motorvehicles, e.g. railway carriages and aircraft. The second Provisional Specification states that the inlet duct may be arranged at the bottom of the vehicle and the extraction duct in the roof.

Title: Improvements relating to the production of semi-conductor devices having alloyed junctions
IPC: H01L21/00
Filed: 1961-03-06
Abstract: 977,328. Semi-conductor devices. TELEFUNKEN A.G. March 6, 1961 [March 4, 1960], No. 8000/61. Heading H1K. An alloyed junction in a semi-conductor device is produced by heating electrode material in a depression on a support and the semi-conductor body to alloying temperature and then bringing the material and body into contact. Fig. 1 shows a semi-conductor body 1 resting on a ledge 3 in a receptacle 2 and held in position by a weight 4 which contacts only the supported regions of the body. A pellet of alloying substance 5 is placed in a depression 6 in support 7, pellet 5 being just sufficient in size to fill depression 6 when molten. Support 7 is placed on a ceramic tube 8 having a temperature-sensitive device 9, and inserted into the bottom of receptacle 2 where it is heated to alloying temperature out of contact with body 1. During heating, undesired impurities may escape by evaporation via slits provided in receptacle 2. The support 7 is then raised to bring the alloying material and the body into contact over a predetermined area against the pressure of weight 4. In a modification (Fig. 3, not shown) the support comprises a plurality of portions each providing a depression, which are used to provide a series of annular electrodes; springs are associated with the portions so that the contacts between the body and the material in each of the depressions may be made successively. Fig. 3 shows a further modification for use in a sliding kiln. The support assembly is situated in a quartz tube 19 through which flow protective gases and contact between the semiconductor body 1 and the molten material in depression 6 is produced by withdrawing slider 20 to allow receptacle 2 to drop downwards. Two adjacent complete support arrangements are provided. A further arrangement is described (Figs. 5 and 6, not shown) suitable for use with a moving belt and a tunnel kiln, in which a lever is rotated to allow the semiconductor support to slide into contact with the support containing the alloying material. The alloying material may consist of indium and the devices may form diodes or transistors.

Abstract: 492,302. Television. GARSIDE, J. W. March 18, 1937, No. 8008. Convention date, March 21, 1936. [Class 40 (iii)] Scanning at the receiver or transmitter of a television system is effected in a series of radial lines by means of a single mirror which is simultaneously rotated and vibrated. As shown the mirror 37 is mounted upon a torsion rod 35 and is vibrated by energizing electromagnets 26, 28 at a frequency related to that of the rod 35, all these elements being in turn supported upon a disc 23 which is revolved by a motor at a speed yielding the number of frames per sec. desired. In order to energize the magnets 26, 28 at a frequency equal to that of the torsion rod 35 or a submultiple thereof, the magnet coils may be connected to a number of polepieces 44 and windings 45 arranged round the disc 23 and co-operating with a number of fixed coils 48 on a stator 46, Fig. 3. For the purpose of scanning a square instead of a circular area a mask be employed, or the amplitude of the vibrations of the mirror 37 may be cyclically varied during each revolution of the disc 23, as shown in Fig. 5. In this arrangement, the windings 30, 32 of the magnets 26, 28 are energized by an alternating current derived from the generator 46 and amplified by a valve 51, the grid bias on which is cyclically varied by a circuit including a valve 57 and a variable condenser which comprises a stator 53 and a rotating armature 52 mounted on the shaft 22 of the disc 23. The shape of the stator may be varied to correspond with that of the area it is desired to scan. For transmitting and receiving stereoscopic pictures, two radial scanning devices operating at different frequencies may be utilized.

Title: Esters of hydroxydihydronorpolycyclopentadienes
IPC: C07C35/22
Filed: 1943-05-20
Abstract: Carboxylic esters of hydroxydihydronorpolycyclopentadiene of the formula <FORM:0566308/IV/1> where n is 0 or a small integer such as 1, 2 or 3, and R is a hydrocarbon or substituted hydrocarbon radical are prepared by reaction of an organic carboxylic acid with a polycyclopentadiene having two double bonds per molecule at below depolymerization temperature of the polycyclopentadiene under acidic conditions. The esters upon saponification give the corresponding alcohols. With strong organic acids, no further acid need be added, but with weak acids, sulphuric or hydrochloric acid, a sulphonic acid, zinc chloride, aluminium chloride, boron trifluoride, or organic complexes of BF3 are added.  In an example, dihydronordicyclopentadienyl formate is prepared from dicyclopentadiene and formic acid, which may be saponified to hydroxydihydronordicyclopentadiene.  Dicyclopentadiene may be replaced by tri, tetra, or penta-cyclopentadiene or homologues thereof.  Other examples give the preparation of esters using acetic, propionic, chloroacetic, levulinic, caproic, crotonic, a -hydroxyisobutyric, lactic, oxalic, salicylic, a -ethyl hexoic, lauric, stearic, oleic, undecylenic, furoic, benzoic, naphthenic, isobutyric, and adipic acid, linseed oil fatty acids and mono esters of phthalic acid.  Other acids which may be used are butyric, valeric, isovaleric, caprylic, capric, myristic, palmitic, glycollic, acrylic, methacrylic, phenylacrylic, cinnamic, di- and tri-chloroacetic, bromoacetic, thiocyanoacetic, a - or b -chloropropionic, chlorocrotonic, methoxyacetic, ethoxyacetic, butoxyacetic, phenoxyacetic, butoxypropionic, undecylenic, linoleic, succinic, pimelic, naphthenic, abietic, naphthoic, tricarballylic, citric, tartaric, chloromaleic, chlorosuccinic and g -acetyl-g -methyl pimelic acid.  The esters may be used as solvents, plasticisers, softening agents for synthetic resins, synthetic or natural rubber, as hydraulic fluids, components for printing inks, nitrocellulose compositions, and as intermediates for insecticides, textile finishing agents, waxes, resins, and wetting agents.

Title: Improvements in or relating to variable speed friction gears
IPC: F16H61/662
Filed: 1931-03-19
Abstract: 374,943. Variable speed friction gearing. FLINT, F. P. and FLINT, A. V., 6, Stanley Road, Edmonton, London. March 19, 1931, No. 8431. [Class 80 (ii).] In variable-speed gearing comprising a roller 5, Fig. 1, engaging overlapping driving and driven friction discs 3, 4 and movable automatically by precession to keep the speed of the driven shaft suitable to the load, the change of resistance of controlling springs 8, 9 to movement of the roller transverse to the line of centres of the discs is proportional to the change in distance of the roller from the axis 2 of the driven disc 4. In the embodiment of Fig. 1, this effect is produced by pivoting the shaft 6 on which the roller 5 slides at a point 7 on the other side of the driving-shaft 1 from the driven shaft 2. When the load changes, the shaft 6 pivots up or down against the spring system 8, 9, and the roller slides by precession along the shaft 6 until it reaches a place where the leverage of the spring system is able to bring the shaft 6 and roller back to the aligned position of equilibrium at a different speed ratio. Arrangements are described comprising multiple gear units as shown in Fig. 1, compounded, the various rollers moving independently. An embodiment shown in Fig 4 comprises interconnected rollers 34, 35 gearing a driving disc 31 to two driven discs 33, 32. The shafts 36, 37 of the two rollers are floatingly supported, the inner end of each being connected through a lever such as 43 to the outer end of the other. The controlling springs 46, 47 may be arranged to act on one of these connecting levers 43 as shown.
