Title: Direct lighting luminaires
IPC: F21V3/00
Filed: 1944-10-25
Abstract: 583,421. Overhead lamps. HOLOPHANE, Ltd. (Holophane Co., Inc.). Oct. 25, 1944, No. 20756. [Classes 75 (ii) and 75 (iv)] A luminaire for a rectilinear light source, L, has end pieces 10 joined by lower tie pieces 13, having upwardly opening channels to receive reflectors 17, and upper tie pieces 12 with flanges which co-operate with clips 30 to hold the reflectors in place. The plane through the light source and the upper edge of a reflector 17 is substantially at right angles to that through the upper and lower edges of the reflector, and the planes through these upper and lower edges and the light source are both inclined at approximately 30‹ to the horizontal. On their inner surfaces, the reflectors 17 have right angled ribs 18 with the incident face of each rib perpendicular to the light from the source L, the concavity of the reflectors being such that light enters the incident face of a rib without deviation, is totally internally reflected and emerges through the other face of the same or a different rib without deviation. The reflector is so shaped that rays of light striking the reflector above the horizontal plane through the light source are reflected away from the vertical axis, while those striking it below the horizontal are reflected across the vertical axis. One supply wire is connected to a terminal of a lamp socket, while the other is led out through the hole 55 and along an arm 11 of the end member to a bushing 56 on the tie piece 13. It passes through the bushing and up the other end member to the other lamp socket, in this way being protected from the heat from the light source. The fixture has a supplemental reflector 31 and ventilation passages 32, and in a modification, the end pieces 10 also extend upwardly and outwardly to hold a reflector with outer totally reflecting prisms to return the upward light to the source L.

Title: Improvements in or relating to vulcanising presses
IPC: B29D30/06
Filed: 1959-06-17
Abstract: 867,135. Tyre vulcanizing presses. CHRISTIANSEN & MEYER. June 17, 1959 [July 23, 1958], No. 20832/59. Class 87(2). A tyre press comprises a fixed lower mould half 2 and heating plate 4, upper movable half 1 and heating plate 3, and an inflatable shaping member 16 which is fixed at its lower end by clamping rings 11, 13 and is moved at its upper end by rings 18, 19 connected to a piston rod 6. The outer diameter of the lower part of the upper ring is made greater than the upper part of the lower ring. It is stated that this helps to remove the tyre from the lower mould half. In operation, with the mould open, vacuum is applied to the member 16 to bring it to the position shown dotted, a tyre canvass is placed on the lower mould half 2, and the upper half 1 lowered on to the rings 18, 19. Compressed air is then supplied to the member 16, and the mould fully closed. The tyre is vulcanized by the plates 3, 4 and by supplying steam through a passage 29 to the member 16. After vulcanization, the mould is opened, and the rings 18, 19 moved upwardly. When the rings have completed their stroke the member 16 is completely withdrawn from the tyre. Vacuum is applied to the member 16 to allow the lower bead ring of the tyre to pass over it. The upper mould half is then moved axially, and an ejector ring 25 pushes the tyre out of the upper mould half on to a grid 27.

Title: Circuit arrangements for correcting demodulated signals
IPC: H04L27/233
Filed: 1977-05-18
Abstract: 1529284 Data transmission SIEMENS AG 18 May 1977 [26 May 1976] 20852/77 Heading H4P In a known demodulator (Fig. 3, not shown) a first demodulated signal is obtained by multiplying a modulated data signal by a first reference signal having a frequency equal to that of the data signal carrier and filtering the product, and a second demodulated signal is similarly obtained by multiplying the modulated data signal by a second reference signal displaced 90 degrees in phase relative to the first reference signal. However, in this known arrangement it is not always possible to regulate the phase angle between the data signal and the first reference signal to the theoretically correct value, and this results in some corruption of the output signals. To correct for this, the invention provides means SS for producing first and second transformation signals S3, S4 corresponding respectively to the cosine and sine of the phase angle between the carrier signal and the first reference signal. The first demodulated signal S1 and the signal S3 are multiplied in M3, whilst the second demodulated signal S2 and the signal S4 are multiplied in M4, the outputs of multipliers M3, M4 being summed in an adder AD 1 to produce a corrected first demodulated signal A. The corrected second demodulated signal B is similarly derived, by way of multipliers M5, M6 and an adder AD2, by summing the product of the signal S1 and a transformation signal S5 (which is an inverted version of signal S4) and the product of the second demodulated signal S2 and signal S6 (which is the same as signal S3). The device SS which produces the transformation signals may be constituted by an arrangement of comparators, gates, a pulse generator and a counter (Fig. 6, not shown), and the way in which this arrangement operates to produce the required corrected signals is described with reference to Fig. 4 (not shown).

Abstract: 736,260. Pressure gauges. HERAEUS GES., W. C. July 29, 1953 [July 29, 1952], No. 21033/53. Class 106 (2). An apparatus for the measurement of low gas pressures comprises a feeler suspended in the gas, heated and cooled surfaces separated by the feeler, and an automatic arresting device adapted to hold the feeler stationary when the apparatus is not in use. The feeler may be a light cylindrical member 4, Figs. 1 and 2, suspended in an air-tight housing 1 connected at 22 to the gas under test. The temperature difference between an electrical heater 7 within the cylindrical member 4, and an outer cooling jacket 16 acts on vaned projections formed in the cylindrical member 4 to cause it to exert a torque the value of which is dependent on the pressure of the gas under test. The deflection of the cylindrical member 4 against the resistance of its suspension means 11 may be optically determined through the medium of a mirror 5 secured to the suspension means 11. The automatic arresting device may be bimetallic elements 10 supported by the heating means and adapted to bear against the cylindrical member 4 whilst the heating means is cold. When the heater is energized the strips 10 deflect in a manner releasing the cylindrical member 4. Various arrangements of the bimetallic strips 10 are described. The instrument is arranged to have two possible temperature differences to enable different pressure ranges to be more accurately gauged. A mirror 25 secured to a bimetallic strip 24 serves to indicate which temperature difference is being employed. The movements of the cylindrical member 4 are damped by eddy currents induced therein by permanent magnets 15.
