Title: Method of and apparatus for determining the extent of a displacement
IPC: F02P17/02
Filed: 1959-10-21
Abstract: 881,418. Method of producing a datum mark on an oscilloscope screen. HUBER, E. W. Oct. 21, 1959 [Oct. 21, 1958], No. 35632/59. Class 37. [Also in Groups XX and XXVII] In a method of producing an " angle " mark on a chart or oscilloscope screen corresponding to a particular angular position (or displacement in time) of the apparatus under test, a stroboscopic lamp 16 illuminates a scale attached to the apparatus simultaneously with the production of the mark, so that the reading corresponding to the mark can be made. The mark is produced on the screen by a pulse derived from stroboscopic unit 17, the pulse simultaneously triggering the lamp and serving as an extinguishing voltage for the C.R.O. trace to produce the mark. Alternatively, for a Duddell oscilloscope, the mark is produced by the lamp or a second similar lamp in response to the triggering pulse. In the embodiment, the apparatus under test is a diesel engine 6, pulses from an induction coil 13 in response to movement of marker 10 over the scale disc 9 triggering a pulse generator 14 the output pulses of which are differentiated and rectified providing control pulses for the triggering pulses of the stroboscopic lamp.

Title: Process for producing tobacco sheets and tobacco sheets obtained according to this process
IPC: A24B3/14
Filed: 1964-09-01
Abstract: A tobacco sheet is produced from tobacco material such as fermented, partially fermented, or unfermented tobacco leaves, leaf fragments, vanes, dust, smalls or shreds, by treating the material at a temperature not exceeding 100 DEG C. with an aqueous solution having a pH of 3-11 of a tobacco extract to release naturally occurring adhesives in the tobacco and form a pulpy mass which is passed on to a belt support and dried.  Alternatively, the tobacco material may be treated at a similar temperature with an aqueous solution (pH 3-11) of formic acid, acetic acid, propionic acid, oxalic acid, glacturonic acid, an inorganic acid such as a phosphoric acid, potassium hydroxide, sodium hydroxide, ammonia, ethylene diamine, ammonium carbonate, primary, secondary or tertiary potassium phosphates or ammonium phosphates or polyphosphates, ammonium formate, sodium acetate, sodium carbonate, potassium carbonate, or the disodium salt of ethylene diamine tetracetic acid.  Quantative examples are given.

Filed: 1970-07-23
Abstract: 1293974 Sink-float separation W L ROLLER 23 July 1970 35693/70 Heading B2H In a process for recovering valuable materials from dead storage batteries, the batteries 60 are first disintegrated in a shredder 50 while the acid content of the batteries is neutralized by a lime-water mixture injected through lines 55, 57, 59. The fragments 52 are then intro-  duced into a separatory vessel 54 containing a separating medium which consists of water and of lead oxide and lead sulphate derived from the batteries and which is maintained at a controlled specific gravity to enable the valuable organic material to float and the valuable inorganic material, viz. lead, lead oxide and lead sulphate, to sink. The organic float material is discharged through an opening 65 onto a first sluice screen 62 where it is washed with a flow of recirculating water 64 from a line 66 and is thereafter discharged at 70. The organic material may then be comminuted, mixed with ingredients to promote its combustibility and briquetted into smudge pots, e.g. for use in citrus orchards. The inorganic sink material is discharged from the base of the vessel 54 and delivered by a pump 80 to a second sluice screen 86 where it is washed with recirculated water 88 from lines 66, 90 and is thereafter discharged, mainly as metallic lead and lead oxide, on to a conveyor 98 and into a furnace where it is melted and then discharged through line 102 into pots 104 to be cast into mats or bullion. The wash water from the sluice screens 62, 86 contains lead oxide and lead sulphate and is directed through lines 91, 92 to a sump 94. From the top of the latter the supernatant liquid is returned as water via line 130 to the vessel 54 and from the bottom the mixture of wash water, lead oxide and lead sulphate is discharged through a line 140 and delivered by a pump 142 to a filter 110. From the filter the water is recirculated by a pump 68 through the line 66 and the filtered lead oxide and lead sulphate are transferred through a line 108 to the conveyor 98 to be also conveyed to the furnace 100.

Title: An improved circuit arrangement for the remote control of the driving motors of telegraph apparatus
IPC: H04L12/12
Filed: 1935-12-24
Abstract: 449,857. Distant - control systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 24, 1935, No. 35741. Convention date, Jan. 9. [Class 40 (i)] [See also Group XL] The motor of a telegraph receiver is controlled by impulses of predetermined length sent from the transmitter over the signal channel while similar impulses produced by interference have interruptions which, however short, cause the controlling circuit to revert to its initial condition. As shown, a line relay M if energized for a short predetermined period keeps its contact L open long enough to allow the relay A to release its contact a in spite of the lag circuit R1, R2, C shunting the contact L. The contact a thus energizes the winding BI of relay B to close the contact b2 in the circuit of the telegraph motor Mo, and the locking contact b1 in the circuit BII. A longer sustained impulse energizes the thermal switch Th through contact a long enough to open its contact th to de-energize the relay B and open the motor circuit. A manual control K2. K3 provides for closing the motor circuit and. that of the self-locking relay B to energize the motor and for opening the latter circuit to de-energize the relay B and hence the motor.

Title: Coding and decoding of data blocks
IPC: H04L9/06
Filed: 1977-09-01
Abstract: To protect data against unauthorised access, particularly in remote data processing, in a data block which is divided into n groups, each of 2 characters, each bit group forms an address for a code group in a code memory (SP), which can be loaded. In a non-linear transformation, this code group replaces the addressing bit group. In a linear transformation, the first character of each data block is shifted to the end. The bit groups are rearranged. These transformations are repeated alternately, in 2n passes. Encryption and decryption use an identical, symmetrical code, with code groups which are inverse to each other in pairs. <IMAGE>

Abstract: 444,424. Discharge apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 24, 1934, No. 37005. Convention date, Dec. 22, 1933. [Class 39 (i)] A gas- or vapour-filled tube comprises an anode of which only the surface turned towards the cathode is exposed to the interior of the vessel, and this surface is so screened from at least a portion of the electron source that some electron paths during the conducting phase are longer than any paths during the nonconducting phase. The lines of force during the nonconducting phase should not differ from each other in their possible length by more than a factor of three. In one form, Fig. 1, the anode 4 and its lead 5 are surrounded by a screen 6, which may be metallic and is then at cathode potential or insulated. The cathode 1 carries a plate 2 such that a discharge could only start between the anode 4 and this plate in the nonconducting phase. The spacing between anode and plate is then so chosen in relation to the gas-pressure that this discharge is inhibited. The cathode 1 may comprise a helical filament surrounding and connected to a support for the plate 2. As shown in Fig. 3, the anode 18 may be surrounded by a metallic screen 19 mounted on an insulating tube 20<1> and subdivided by screens 20, 21, 22. The open end of the screen 19 may be covered with gauze and the screen may be used for control purposes. In a modification, the filament 1 may be dispensed with and the plate 2 covered, at least on its lower face, with emitting material. The cathode may also be constituted by a discharge gap or may be liquid. Further control electrodes, for example, an ignition electrode on the underside of the plate 2, may be added. The filling may consist of mercury, or nitrogen, hydrogen, or iodine, or mixtures. According to the Specification as open to inspection under Sect. 91, a conductor 23, Fig. 4 (Cancelled), enclosed in a high potential electrode 24 is spaced therefrom by insulating bars 25, 26 carrying ceramic collars 27, 28 and, if desired, metal collars 29, 30.

Abstract: 1,027,354. Electrophotographic apparatus. RANK XEROX Ltd. Sept. 20,1963 [Oct. 1,1962], No.37066/63. Heading G2H. [Also in Division H1] In an automatic electrophotographic copying machine, adapted for reproducing continuous tone originals, utilizing an electrophotographic plate with a substrate containing an optical screen provided with a pattern of small, alternating, discrete transparent and opaqueareos (see Division H1), the plate is in the form of a transparent drum 21 supporting an optical screen 22 and a photoconductive insulating layer 23. An earthed conductive contact is made to the inside face of the photoconductive layer 23 either by making the screen 22 or conductive material or by interposing a thin transparent conductive layer between the screen 22 and the layer 23. The plate is charged by a corona discharge apparatus 26 and exposed to an image produced by projector 28. The inside of the drum is simultaneously illuminated by source 24. The optical screen 22 allows small "islands" of photoconductive layer 23 to be discharged thus breaking up the areas of charge to produce better reproduction of large areas of tone due to the strong fringing fields obtained. The plate is developed by cascading a mixture 32 of carrier beads and toner particles over the plate. A copy web 36 is pressed against the drum by idlers 37 and a unit 38 transfers the toner particles to web 36 by corona discharge. Alternatively, web 36 may be adhesive to the toner particles. The image on the web is fixed by heating unit 39 and the plate is cleaned by brush 42. With screen patterns coarser than about 80 lines per inch the pattern is visible after development but with finer screens this effect becomes negligible. The light source 24 is switched off when reproducing line copies since superimposition of the screening pattern breaks up the strong fringing fields present and reduces the quality of the copies.
