Title: Vehicle space heating installation
IPC: B60H1/18
Filed: 1962-06-15
Abstract: 946,042. Heating vehicles; heating air by I.C. engine exhaust. F. A. E. PORSCHE. June 15, 1962 [June 27, 1961], No. 23176/62. Headings F4S, and F4V. In a motor vehicle heating installation, a separate blower, mounted at the end of an internal combustion engine opposite to that from which the main drive is taken, supplies fresh air, which is heated by the engine exhaust gases in a silencer constructed as a heat exchanger and disposed directly below the blower, to a space in the vehicle. As shown, Fig. 1, a vehicle 1 is powered by a rear-mounted air cooled engine 2, whose two rows of cylinders are supplied with cooling air by blowers 3 and 4 which are belt-driven from the engine crankshaft 7, Fig. 2. The engine cooling air reaches the blowers through vertical slots 13 in a rear cover panel 12, and through apertures 14, Fig. 2, in a cross bearer 15 of the vehicle body. The blower 27 for the heating installation is coaxial with the blower 4 and is driven through a flexible shaft 28 having a splined portion 29 slidably engaging in a splined sleeve 30, which may be moulded integrally with a synthetic plastic impeller 31. Fresh air is drawn into ducts 36, 37 through slots 42, 43 behind the vehicle rear window, and passes down to the ends of a box section 33 formed by a channel portion of the cross bearer 15 and a closure plate 32. The air enters the blower 27 through an inlet duct 34 and is passed down through a short duct 47 to the heat exchanger/silencer assembly 23, where it passes along passages formed by a corrugated member 54 separating an outer wall 52 and an inner wall 48 which latter constitutes the upper half of the silencer. The lower half 49 of the silencer is of much lighter construction and carries the exhaust inlet and outlet connections and cross walls 56 which divide the silencer into a number of closed chambers, interconnected by short pipes 57 piercing the walls 56. The heated fresh air passes through connections 58, 59 to distribution ducts 60, 61 respectively. A flap valve (Fig. 3, not shown) may be arranged at the outlet of the blower 27 to divert some or all of the air to a by-pass duct 64 which leads unheated air direct to the distribution ducts.

Class 20(2) In a fluid pressure actuated mine roof support system a pressure pipe 9, Fig. 1. and a return flow pipe 10 are connected to groups of props 3 constituting individual support frames 1, 2 adapted for alternate advancing movements by operation of horizontal piston and cylinder unit 5 connected between pairs of frames 1, 2, the connection between each of the groups of props 3 and the pipes 9, 10 being made by means of a reversing valve 8 and a differential pressure safety valve 7. The safety valve 7 comprises a poppet valve 20 formed on a piston having three portions 19a, 19b and 19c, Fig. 4 slidably mounted in a chamber in a valve housing 23 having portions 22a, 22b and 22c of different diameters. The chamber 22c is connected to a passage 33 which communicates with the pressure pipe 9 by way of the reversing valve member 8 and a bore 29. The chamber 22c also communicates through a restricted passage 21 with a bore 28 to which the associated group of props is connected. The eross-sectional areas F', F<SP>2</SP>, F<SP>3</SP> and F<SP>4</SP>, and the crosssectional area of the passage 21 are so proportioned that in the event of loss of pressure in the pressure pipe 9, the poppet valve 20 will close to seal the prop cylinders connected to the bore 28 against loss of pressure and the valve 20 will remain open as long as the pressure in the pipe 9 does not fall below a predetermined value at a rate in excess of a predetermined rate. The reversing valve member 8 consists of a rotatable conical plug 24 having a bore 24a which can be positioned to place the prop cylinders in communication with the pressure pipe 9 or may be rotated through 90 degrees to the position shown in Fig. 4 in which the bore 24a completes a passage from the prop cylinders connected to the bore 28 to the return flow pipe 10. The plug 24 is forced against its seat by the resultant of forces acting in opposition against the conical surface of the plug and the annular surface K<SP>2</SP>. A spring 36 maintains the seal of the conical surface of the plug in the event of a complete failure of pressure. Specifications 750,293 and 781,644 [hoth in Group XXIX] are referred to.

Filed: 1967-05-19
Abstract: 1,126,392. Polarizing devices. STANDARD TELEPHONES & CABLES Ltd. May 19, 1967, No. 23388/67. Heading G2J. A linear optical polarizer comprising multiple layers 50 of transparent thin film dielectric layers on a glass plate 51 is arranged such that for a particular wavelength and angle of incidence, an incident beam of light plane polarized normal to the plane of incidence gives rise to a reflected beam which is the resultant sum of the components reflected from each layer, whereas, a similar incident beam plane polarized parallel to the planes of incidence is incident on some layers at more than the Brewster angle and on other layers at less than the Brewster angle, so that the resultant of the reflected components has zero amplitude. This system gives 99% reflection of incident light polarized normal to the plane of incidence, and 99% transmission of light polarized parallel to the plane of incidence. The thin film layers are alternately of 1À35 and 1À50 refractive index and are of a thickness giving an optical path difference which is an odd number of half wavelengths between light reflected at the top and bottom of each layer. The layers are of cryolite and a higher oxide of silicon, and an anti-reflection layer 52 of zinc sulphide is provided on the underside of the glass 51.

Abstract: 462,027. Discharge apparatus; thermionic valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 26, 1935, Nos. 23873, 23874, and 23875. Convention dates, Aug. 24, 1934, Aug. 25, 1934, and Aug. 25, 1934. Drawings to Specification. [Classes 39 (i) and 40 (v)] An electric discharge device has within its envelope a " negative resistance, connected either in parallel with the discharge path, or in series with the cathode lead. A " negative " resistance is one which, by virtue of a negative temperature coefficient of resistance, carries a voltage independent of the current passing through it over a certain range. The parallel connected resistance serves to maintain the anode voltage constant in spite of variations of supply voltage, which are taken up by a series ohmic resistance. The resistance in the cathode lead supplies grid bias which is independent of variations of the anode current. Both resistances may be used simultaneously in the same device. The grid bias resistor may include an ohmic resistance which may also form part of the resistance connected in series with the negative resistance in parallel with the discharge path. The resistance materials are preferably electron-conductive metal oxides such as those of uranium, chromium, cobalt and manganese, formed into rods. To enable the negative resistances to work at the correct temperature they may be heated by placing them in reflectors collecting heat from the hot electrodes of the discharge device or by coating them with white aluminium oxide, barium sulphate or magnesium oxide ; or they may be cooled by screens protecting them from hot electrodes or by coating them with black carbon dust. High resistances may be provided with a core of refractory material such as thorium, magnesium or aluminium oxides, to increase their mechanical strength. Other ohmic circuit resistances may be mounted in the envelope.
