Title: Improvements in angle determining instrument somewhat like a sextant
IPC: G01C1/08
Filed: 1931-04-07
Abstract: 374,992. Angle-measuring instruments. MACNEIL, P. H., Huntington, New York, U.S.A. April 7,1931, No. 10279. Convention date, Nov. 24, 1930. [Classes 97 (ii) and 97 (iii).] An angle-measuring instrument comprises an infra-red ray detector, a frame, a swinging member pivoted to the frame and provided with a tubular extension for admitting rays to the detector, and means for indicating the angle between the swinging member and the horizon. The instrument may be used for measuring the altitude of the sun in a fog. In the form shown the frame 1 carries a graduated arc 2 and a hollow hub 20 into one end of which is threaded a plug 25 supporting a handle 32 for holding the instrument and a heat-sensitive element 4 such as a thermocouple, photo-electric cell or a temperature-sensitive electric resistance. A swinging arm 17 is provided with a hub 19 fitting telescopically over the hub 20 and a tubular extension 22 for directing heat rays on to the sensitive member 4. Part of the tube 22 is cut away almost along its full length and a sector shaped shield 23 having a hub 24 surrounding the hub 19 coacts with the opening thus formed to provide an enlarged funnel for directing heat rays on to the element 4 when locating the hot body. The sensitive element 4 is connected if desired through a booster or relay to a voltmeter or galvanometer 8 the indications of which are reflected by a mirror 7 into a telescope 6 fixed to the frame 1. The instrument is levelled by swinging a hinged part of the mirror 7 out of position and sighting the horizon directly through the telescope 6 or a bubble level on the meter 8 is used as an artificial horizon. In use the instrument is levelled, the hot body located and the shield 23 moved to close the aperture in the tube 22. The swinging arm 17 is then moved until the meter 8 registers its maximum deflection and the angle of altitude of the hot body, e.g. the sun, is read off on the scale 2. In a modification the tube 2 may be replaced by a cylinder of greater diameter having at its bottom a parabolic reflector for focusing heat rays on to the element 4 suitably located in the cylinder. Alternatively a lens may be used for refracting the heat rays on to the element 4.

Title: Improvements in or relating to the manufacture of artificial teeth
IPC: C04B33/32
Filed: 1950-04-27
Abstract: Ceramic masses are fired under reduced pressure or in a highly diffused atmosphere.  The process is particularly applied to artificial teeth composed of quartz, feldspar and kaolin with the possible addition of opacifying agents e.g. zirconium oxide, and colouring agents e.g. titanium dioxide, chromic oxide.  Binders e.g. starch, dextrin, may be added in forming the green teeth, but are burnt out in the firing which is partially conducted under a vacuum ranging from complete to 20 inches below atmospheric. Alternatively, the firing may be partially in a highly diffused gas or mixtures of such gases e.g. helium and hydrogen or the two firing techniques may be combined.  The firing is preferably carried out in three stages, firstly in a normal furnace in an oxidising atmosphere at 900 DEG -1000 DEG  C., secondly in an electrically heated furnace (see Group XI) under vacuum or in a diffused gas or both, and at a temperature of 1350 DEG  C., and thirdly, in the second furnace, under air at atmospheric pressure, at 1350 DEG  C. or even under increased pressure.  In a modification, this third stage is omitted.  All firing stages may be conducted in one furnace, and the firing may range between 800 DEG  and 1500 DEG  C. Specifications 254,075, [Class 81 (ii)], and 498,806 are referred to.ALSO:Artificial teeth are prepared from a ceramic mix of quartz, kaolin and feldspar by firing under a vacuum (complete or partial) or in a highly diffused gas, or a combination of both.  Under such conditions a more homogeneous tooth is obtained, one which is stronger and wherein the vesicular structure is substantially eliminated.  The tooth is more translucent, and may even be completely so.  Colouring and opacifying agents may be added to simulate natural teeth (see Group V). Specifications 254,075, [Class 81 (ii)], and 498,806 are referred to.

Title: A new or improved marking implement
IPC: F22B13/12
Filed: 1936-04-09
Abstract: A marking-implement, in solid form, is made of a composition comprising a pigment, a solid carrier therefor, a drying oil, and a drying accelerator for such oil, the implement having a hard removable surface film, formed by exposure of the composition to air, the said film maintaining the interior portion of the marking implement in unhardened condition.  According to an example, pine rosin and linseed oil are melted together, and cobalt acetate and lead subcarbonate are added to form driers.  Titanox and oleo-stearin are then added, and the mixture poured into moulds to form pencil-like marking implements.  A hard surface film develops after exposure to air for a few hours, and, before using the implement, a portion of this film is scraped off.  Salts of manganese or nickel may be substituted for the metallic salts mentioned above, other pigments may be used, tung oil may be used instead of linseed oil, and other solid fatty materials may be used instead of the oleo-stearin.  The Specification as open to inspection under Sect. 91, mentions the use of perilla oil and of a mixture of stearin and paraffin as ingredients of the composition, but this subject-matter does not appear in the Specification as accepted.

Title: Electric pulse communication systems
IPC: H04J3/00
Filed: 1946-04-06
Abstract: 610,464. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. April 6, 1946, No. 10664. Convention date, Aug. 25, 1944. [Class 40 (v)] In a pulse multichannel communication system, spaced segments from the signals of a number of channels are interleaved together and used to time modulate the transmitted pulses. In one embodiment, a base pulse producer 4 feeds pulses at the repetition frequency of each individual channel through a pulse shaper 8 to a delay line 10 to deblock each channel amplifier 12 in turn, thus producing spaced pulses of amplitude corresponding to the instantaneous signal value of each channel. Unmodulated pulses at the repetition frequency of the system as a whole are fed to phase modulator 19 by a pulse multiplier 6 controlled by pulse producer 4. The output pulses from 19, modulated in accordance with amplitudes of the signal sectments from amplifiers 12, are fed to a clipper mixer 21 together with synchronizing pulses from shaper 8 or a separate pulse shaper 8a. The output of mixer 21 modulates a transmitter 23. The time modulator, Fig. 3 (not shown), may be of the type in which the unmodulated pulses and the signal segments are fed to a delay network including a cored coil, the inductance of which varies with the amplitude of the signal pulses, to delay the channel pulses by varying amounts. The synchronizing pulses are distinguished from the signal channel pulses by width. In a modification, Fig. 4 (not shown), pulses at the repetition frequency of the system as a whole are fed through a pulse divider to provide synchronizing pulses and deblocking pulses for the channel amplifiers. The pulses also control a wave producer, the triangular wave output of which is fed to a gate clipper together with the signal segments to provide width modulated pulses, which are differentiated and clipped. The resulting phase modulated pulses are mixed with the synchronizing pulses, and clipped to provide pulses for modulating the transmitter.
