Filed: 1945-07-31
Abstract: 627,965. Panel heaters; electric fires. DAY & NIGHT MANUFACTURING CO. July 31, 1945, No. 19625. Convention date, Aug. 15,1944. [Classes 39(iii) and 126] A space heater operated by gas which issues from a burner located at the lower end of a tube constituting the heating element and having a vent at the opposite end of the tube for carrying off products of combustion includes a collector box 60, Fig. 3, for said combustion products which is open at its outer or front end, said opening being covered by a louvred plate 92, is mounted on a shelf 55 closing off the upper end of a reflector 23 partly surrounding the heating' tube 30 through which shelf the upper end of said tube protrudes, and is connected to a flue 65 the outlet being restricted by a down draft baffle 67 in the form of an inverted channel member. The heating tube 30 has a baffle 35 depending from a tube cap 33 with an eccentrically located opening 34 and indentations 31 are struck in the tube opposite the faces of said baffle. A protective casing 24 encloses the sides and back of the unit and a false flue 76 surrounds the flue 65 which discharges into an asbestos cement or like outlet flue 78, Fig. 10. The whole structure forms a panel heater attached to and installed in the wall W, Fig. 7, of a room being secured in position by screws 88 passing through side moulding units 85 attached to the reflector 23 and casing 24. A number of modifications incorporating the same downdraft construction and mounted in the dividing wall of a room show combinations, either front or back-to-back or both, of two or more heating elements and also a single unit with back-to-back reflector constructions designed to heat two rooms at once, independent control of the gas supply from either room being shown. One single unit Fig. 26 (not shown) has a back-to-back reflector construction whereby a larger arc of the heating tube is exposed on one side than on the other. The Specification as open to inspection under Sect. 91 discloses a double back-toback reflector construction serving two rooms in which long vertical electrical resistor elements replace the heating tubes, Fig. 29 (not shown). This subject-matter does not appear in the Specification as accepted.

Abstract: 1444324 Window for a sloping roof VBK RASMUSSEN 3 May 1974 [15 May 1973 6 Sept 1973] 19646/74 Heading E1J A window for mounting in a non-horizontal position comprises a main frame 1, 2, 3 and a sash 4, 5, 6 with pivots 7 and links 9 hing- edly attached at or near the lower sash member 6 and at or near the mid-point of the side member of the main frame. The pivots 7 may be attached to the sash and slide in the tracks 8 in the side members 2 of the main frame or may be attached to the main frame and slide in tracks in the side members of the sash. The torsion bar 10 biases the arms 11 upwardly so that the shoes 12 sliding in the grooves 13 partially counter balance the weight of the sash during opening and when open; this may be replaced by a system of cords and weights or springs. The sash may be reversed for cleaning by releasing the pivot 7 from the track 8 through the exit slot 14 or by other means. When open the sash frame does not obscure the view or block the opening so that it may be used as an emergency exit.

Title: Improvements in or relating to methods of manufacturing unitary solid state electronic circuit complexes and to said complexes
IPC: H01L21/761
Filed: 1960-06-08
Abstract: 959,667. Semi-conductor circuits complexes. FAIRCHILD CAMERA & INSTRUMENT CORPORATION. June 8, 1960 [Sept. 11, 1959], No. 20055/60. Heading H1K. A circuit complex is made by forming a wafer of intrinsic semi-conductor material and controllably deffusing selected impurities into it to form separated zones of extrinsic material. These are then developed into discrete semiconductor devices each of which is provided with at least one electrical contact. In one arrangement the separated zones are of the same conductivity type. The isolation between them may be improved by including a zone of opposite conductivity type between the intrinsic region and one or more of the zones. A similar improvement is produced by providing a zone of opposite conductivity type in the intrinsic zone between adjacent separated zones. In the above arrangements if the intermediate zones are thick enough to prevent transistor action between the separated zones the latter are coupled only through the reverse resistance of a PN-junction and the intrinsic region in series for direct voltages but through the capacity of the junctions for alternating voltages. The capacity is, however, small where each junction is associated with an intrinsic region. A typical arrangement comprising a pair of transistors is shown in Fig. 10 and consists of two zones 102, 103 of N-type antimony-doped silicon forming the collector zones, isolated by an intrinsic region 109 flanked by P zones 104, 107. The collector and P zones 104, 107 are formed by diffusion of donor and acceptor impurities respectively through masks from both faces of an intrinsic wafer simultaneously and the base zones 111, 113 and emitter zones 112, 114 by subsequent diffusion of appropriate impurities. A conductive channel 118 through the intrinsic region is produced by forming a molten zone containing gold on one face of the wafer and then passing it through the thickness of the wafer by zonemelting. Plated connections to the various zones are made, as shown, through holes etched in a protective silicon suboxide layer 116. Intrinsic material for the original wafer is either highly purified silicon or doped silicon the impurities in which have been rendered ineffective by diffusion therein of a deep level impurity such as gold.

Title: Improvements in or relating to a device for creating a human or animal body
IPC: A61H9/00
Filed: 1963-05-21
Abstract: 979,094. Treatment chambers. N. A. MACLEOD. May 21, 1963, No. 20066/63. Heading A5R. A device for creating pressure variations in the body comprises a chamber for liquid under pressure, the chamber having a sealable opening for receiving the body or a part thereof and means for creating pressure pulses in the liquid when in the chamber. The opening 11 is closed around the body part by inflating a tube 13. As the chamber is filled with liquid, e.g. water, through an inlet 19, air escapes through a manometer 20. The liquid is maintained at the desired temperature by circulating it by a pump through a heat exchanger 24. The pressure of liquid in the chamber is varied by a piston 32 reciprocated in a cylinder 31 communicating with the chamber. The piston is connected for reciprocation by rods 34, 39 to an eccentric pin 41 which is rotated by a motor 45. The piston and cylinder may be replaced by a flexible diaphragm (Fig. 3, not shown) which forms the closed end of the chamber and which is connected for reciprocation to a pin which travels in an eccentric cam groove rotated by the motor. Additional means for -varying the liquid pressure may comprise a piston adjustably fixed in a cylinder, which communicates with the chamber, or a piston operated by a solenoid against a spring to provide an increase or decrease in pressure of short duration. The chamber may be constructed to receive the whole body of the patient who is provided with a breathing mask. The apparatus and the patient may be disposed in an enclosure in which the air pressure is greater than atmospheric by 1 to 50 1bs. per square inch.

The ring is made by the sequence of steps shown in Fig. 3. The metal may be steel having a higher carbon content adjacent that periphery which will provide-the raceway surface. Gear teeth may be cut in the periphery remote from the raceway, or a mounting member welded thereto. Centrifugal casting.-The initial casting process is carried out in the apparatus shown in Fig. 4. The metals (e.g. steels of differing carbon content) which are to form the outer and inner layers of the cast tube from which the rings will be cut are supplied to the rotating mould sequentially. By control of the intervening time period, the layers merge to form a unitary body. Roll forging.-The heated ring is roll forged in the apparatus shown in Fig. 10. The ring is rotated by a drive roll 41, and radial pressure is applied by a roll 43 supported by movable members 45, 46. Guide rolls 44 can be applied to the outer periphery of the ring.
