Title: Silicing apparatus
IPC: B26D7/32
Filed: 1974-02-22
Abstract: 1456306 Slicing apparatus PETER ECKRICH & SONS Inc 22 Feb 1974 [16 April 1973] 8271/74 Heading A4C In a slicing apparatus comprising a rotary knife 12, a feeding mechanism consisting of chains 26, 28 to engage, e.g. a loaf, therebetween, and a forklike slice-receiver 68 consisting of tines 70, the slicereceiver 68 being adjustable by tilting it about a horizontal axis lying in the plane of the slicereceiver and passing through the centres of curvature 120 of four arcuate slots 116 in parallel guideplates 118 by manually operating a knob 140. This also tilts a weigh cell 76, a housing 144, a support rod 102 for the slice receiver and an inverted cup-like housing 152 surrounding the opening of a tube 154 having an oblong cross-section about the above mentioned horizontal axis through the movements of four rollers 114. The slice-receiver can also be tilted about a pin 88 perpendicular to said horizontal axis, the pin being in the plane of the slice-receiver, and can be rotated in its own plane. When a desired weight of the slices on the slice-receiver, indicated by the weigh cell 76 which is mechanically connected to the slice-receiver via the support rod 102, is obtained, a solenoid 156 is energized to extend a rod 158 and thereby to move a second fork-like structure comprising tines 162 along a slot 164 in a guide-plate 150 to a dotted-line position, Fig.2. This pushes the slices off the tines 70 on to a conveyer belt 74. The housing 152 and a'base-plate 108 along with its extension 130 shields the weigh cell 76 from the debris during slicing operation. A control motor adjusts the position of the knife 12 in the cutting area by extending or lowering a shaft 16.
Patent GB-714588-A (GB)
Title: Method of desulphurizing carbon-coated electrodes
IPC: H01J19/00
Filed: 1951-04-10
Abstract: A method of desulphurizing a carbon-coated electrode comprises heating the electrode in an atmosphere of hydrogen mixed with a relatively large percentage of inert gas, the heat treatment being continued sufficiently long to ensure that substantially all of the sulphur is removed but not continued thereafter for a sufficient length of time to give rise to the formation of methane, whereby the desulphurization is effected with little or no loss of carbon from the electrode coating.  The inert gas is nitrogen, helium or neon and the hydrogen comprises 5-10 per cent. by volume of the mixture.  The mixture of hydrogen and inert gas is passed over the electrode heated in a furnace to a temperature of from 900 to 1100 DEG  C. so that the electrode as well as being desulphurized is also outgassed.  In an example a carbon-coated nickel electrode is desulphurized by passing a mixture of approximately 7 per cent. by volume of hydrogen over the electrode heated at atmospheric pressure in a tubular furnace, which can be of the type described in U.S.A.  Specification 2,314,816, to a temperature of approximately 1000 DEG  C. for a period of approximately 15 minutes.  The rate of flow of the gaseous mixture is approximately one litre per minute per square inch of internal cross-sectional area of the furnace.  After the heat treatment the electrode is moved to a cooling zone of the furnace where it is still subjected to the gaseous mixture and is subsequently removed from the furnace when it has cooled to room temperature.

Filed: 1928-03-20
Abstract: 287,488. Soc. Civile pour l'Etude de la Photographie et de la Cinematographie en Couleurs. March 21, 1927, [Convention date]. Drawings to Specification. Diaphragms.-In taking colour records on films bearing a system of minute linear lenticular elements, or in reproducing such records by optical projection upon similar films, there is employed in the optical system a slit diaphragm arranged at right angles to the direction of the lenticular elements and therefore also to the direction of the juxtaposed colour filters employed in the system. The arrangement not only permits a reduction of the aperture (in the direction of its width) which will affect all three colour filters equally, but also reduces the effect of internal reflections in the film, and also, particularly in the case of reproduction, reduces the liability to watering.

Title: Improvements in thermal engines for example jet propulsion units and gas turbine engines
Inventor: KADOSCH MARCEL
IPC: F02C7/04
Filed: 1952-04-04
Abstract: 722,544. Gas-turbine plant; jet-propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 4, 1952 [May 30, 1951], No. 8721/52. Class 110 (3). [Also in Groups XII and XXVIII] The air supply to a jet-propulsion or gas-turbine engine with continuous combustion is partly or wholly compressed by forcing the air through a nozzle by means of a pulsating steam jet. The air supply to the ram jet propulsion unit shown is compressed in a diffuser 2 and then passed into a combustion chamber 3 through a nozzle 4 in which its pressure is increased by means of a pulsating steam jet 5. Water from a tank 10 is forced by means of a pump 9 through a combustion chamber jacket 11 having a helical partition 12 to a vaporizing coil 8 from which it passes through a pulsator 13 to the jet 5. The pulsator 13 may comprise a disc, rotating in a plane perpendicular to the conduit 5a, formed with a series of circumferentially aligned holes. Another form of pulsator, Fig. 3, comprises a cylindrical casing 14 mounted in the pipe 5a in which a rod 16 driven by an eccentric 18 reciprocates. A recess 20 in the rod co-operates with ports 15 to interrupt the flow of steam. To obtain a sharp cut-off and release of the steam, the width of the recess 20 is made smaller than that of the ports 15. The casing 14 is attached to the head 14b containing the eccentric by a nut 14c formed with two threads of opposite hand 14d and 14e so that rotation of the nut 14c allows the casing 14 to be moved closer to or farther from the head 14b to adjust the period during which steam is supplied. In a modification as applied to a gas-turbine plant, the pulsating steam jet is used to further compress the air leaving the compressor before it enters the combustion chamber. It is stated that the invention may also be applied to a plant in which a compressor is driven by a reciprocating or other engine.

Abstract: 680,002. Magnetic induction accelerators. METROPOLLTAN-VICKERS ELECTRICAL CO., Ltd. March 20, 1950 [April 4, 1949], No. 9125/49. Class 39(i) In a betatron which has the inner surface of the accelerating chamber coated with a layer of silver, graphite or other suitable conductive material, the layer is biased negatively with respect to the anode of the injector. This is in order to obtain such a contraction of the orbital radius of the electrons after injection as to ensure that they do not hit the injector after completing a revolution in the chamber. The phase of the injector pulses is advanced with respect to the times of zero magnetic flux in such manner as to oppose the tendency of the electrons to oscillate in the region of the injector due to the strong field there. A prior proposal for contracting the orbit in which energy is abstracted from the electron beam by passing a rapidly changing current through conductors placed above and below the beam orbit, is referred to.

Title: Manufacture of alcohols from marine animal waxes
IPC: C07C29/147
Filed: 1933-03-27
Abstract: Alcohols are produced by the reduction of marine animal waxes such as spermaceti and sperm oil by treatment with sodium and a lower aliphatic alcohol such as ethyl or butyl alcohol.  In an example, sperm oil freed from moisture is mixed with ethyl alcohol and molten sodium is added with agitation, the reaction mixture being finally heated to about 150 DEG  C.  Alcohol is added to combine with any remaining sodium, and then water is slowly added and the mixture is allowed to stand.  The aqueous layer is then removed, and the alcohols are purified if necessary by distillation in super-heated steam.  The alcohols are suitable for the production of sulphuric esters.
