Title: Method and apparatus for the continuous demoisturising of leather and like fibrous materials
IPC: C14B1/00
Filed: 1969-02-20
Abstract: 1,221,165. Demoisturizing leather. MASCHINENFABRIK TURNER A.G. Feb.20, 1969, No.9209/69. Heading C6C. Leather is continuously demoisturized by feeding it between a pair of endless conveyer belts 2, 3 which are constructed of permeable material having a capacity of retaining moisture at least by a surface tension effect and which are resilient at least in a direction at right angles to the belt surfaces, whereby moisture can be transferred from the leather to the belts by applying pressure to the conveyer belt - leather - conveyer belt sandwich, there being provided, in addition to such pressure-applying means, means for passing a current of air through the belts or /and for shaking the belts to remove the collected moisture either before or after separation of the belts to discharge the squeezed leather. In the embodiment of Fig. 1, the leather is gripped between the belts 2, 3 and the sandwich passed successively between a first pair of plates 13 to which pressure is applied in the directions of arrows 5, so that most of the water 6 contained in the leather is squeezed out and retained in the belts 2, 3, between a pair of suction nozzles 8 to which suction is applied to withdraw the water 6 from the belts, and then between a second pair of plates 13 which are vibrated in the direction of arrows 12 to extract more water from the leather, the belts then being separated by being passed over rollers 15 and the further water being removed from the belts either by blasts of air from a conduit 17, which drive the water into collecting ducts 18, or by a shaker plate 11, which shakes the water into a trough 20, or by a combination of both these methods. In an alternative embodiment Fig. 4 (not shown). The water is caused to be transferred from the leather to the belts (2, 3) by passing the belt - leather - belt sandwich over a bar (14) which causes a sudden change in direction of the sandwich, the bar incorporating an air nozzle which drives the water from the leather. Suction nozzles thereafter remove the water from the belts. Each belt consists of a plurality of resilient rubbery or plastic fibres in the form of a mesh, Fig.2, sufficiently fine for water to be retained by a surface tension effect.

Title: A process for the preparation of saturated or unsaturated cyclododecanones
IPC: C07C45/58
Filed: 1959-03-17
Abstract: 1,2-Epoxycyclododecane and 1,2-epoxycyclododecadi-5,9-ene are rearranged to the corresponding cyclododecanone and cyclododecadienone by heating with a catalytic quantity of a polyvalent metal salt which is combined with an organic electron donor, such as an ether, ketone or epoxide, to form a Lewis acid complex.  The metal salt may be a halide of a polyvalent metal of the 2nd or 3rd Group of the Periodic Table or of iron or another salt of magnesium.  Temperatures of 50 DEG -200 DEG C. are preferred.  A solvent may be present.  In Examples: (1) the epoxycyclododecane is rearranged using an ethereal magnesium bromide or iodide or aluminium bromide solution or magnesium iodide or perchlorate or zinc chloride, bromide or iodide, which form catalyst complexes with the epoxide reactant; (2) the epoxy diene is rearranged using ethereal magnesium iodide solution.  Specification 849,238 is referred to.

Title: Electric control of temperature and other conditions by means of conditionresponsive contact-carrying instruments
IPC: H01H47/22
Filed: 1949-04-05
Abstract: 659,449. Automatic temperature control systems. BUSER, T., and SAIA AKT.-GES. FUR SCHALTAPPARATE. April 5, 1949, No. 9283. [Class 38 (iv)] [Also in Group XXXVII] In an arrangement wherein a temperatureresponsive or other instrument z controls the current to a load v by engaging maximum or minimum contacts which control relays 1, 2, these contacts are adapted to take only the small current required to demagnetize relays 1, 2 whose armatures are held by remanent magnetism, and the circuit through these contacts is broken elsewhere. The relays 1, 2 each comprises an L-shaped armature 9 held in the position shown by a contact spring 11 and adapted when attracted to open contacts 12 and close contacts 13. The armatures of the two relays also co-operate with a centrally-pivoted rocker 21 controlled by a dead-centre spring 18 and carrying two arms 15, 16 each carrying contacts 22, 23. The arm 16 is situated behind the arm 15, Fig. 1. Energization of either relay will pull down its end of the rocker if it is not already in that position and subsequent release of the relay will have no effect on the rocker. In Fig. 4, relay 1 is " released " and relay 2 has its armature held by remanent magnetism. When, with change of temperature, the instrument z engages its maximum contact, a small A.C. demagnetizing current passes through the resistance W2 and the relay coil 2 causing release of its armature, breaking of the load circuit v and of the demagnetizing current at 2a and completion at 2r of a circuit to relay 1 which operates its contacts 1a and 1r and reverses the position of rockers 15, 16, thereby breaking the relay circuit at 15a and preparing at 1a a demagnetizing circuit for the relay 1. This latter circuit is completed when the instrument z engages its minimum contact, whereupon relay 1 releases and completes a circuit through relay which brings all parts back to their original positions.

Title: Improvements in or relating to teleprinters for page printing
IPC: H04L13/06
Filed: 1954-03-30
Abstract: 739,763. Type-printing telegraphy. AUTELCA AKT.-GES. March 30, 1954 [Nov. 25, 1953], No. 9338/54. Class 40 (3). In a page - printing teleprinter comprising a marking device for printing a symbol serving to distinguish incoming from outgoing messages and operated solely during one direction of traffic, a symbol stamp is provided with coupling means which, on energization of an electromagnet, move into operating relation with means provided for the operation of the marking device, the closure of the energizing circuit of the magnet being dependent upon the operation of a contact by a cam disc which rotates solely during operation of the teleprinter in the one traffic direction. The symbol stamp having a printing head 14 is rotatably and axially movable in limbs 15, 16 of a member 20 fixed to the printing carriage and carries a lever 10 having an arm 10a normally held by a spring 11 in a slot 9 of a cheek 12 of the member 20. If the device is to be operated for outward-going messages a cam 2 on the transmitter shaft 1 closes contacts 3, which in conjunction with contacts 17 closed when the printing carriage is at the beginning of a line, energize a magnet 4 rocking an arm 6 and depressing a lever 8 so that the arm 10a is moved clear of the notch 9 and the stamp member moves to the left under the action of the spring 11 with the upper surface of the arm 10a in engagement with the non-recessed portion of the cheek 12. The other arm 10b of the lever is riveted into the path of a member 18 on the printing carriage so that its movement to the right to print a character on the platen 21 moves the shaft 13 and the type-head 14 to print a symbol at the beginning of a line. The stamp and shaft move to the left under the action of the spring 11, and the magnet 4 being de-energized, the arm 10a snaps back into the notch 9 in the cheek 12. In a modification, Fig. 4, in which the symbol member 26 is operated by the line-shift mechanism, the symbol stamp 26 is mounted on a pivoted lever 29 carrying an operating arm 30 normally biased by a spring 33 so that a coupling pin 32 is out of the range of a cam on an arm 22 which is rocked to provide the line-feed movement. When the line-feed signal is transmitted, contacts closed by the carriage at the beginning of a line and by a cam on the transmitting shaft energize the magnet 34 which brings the pin 32 into operative relation with the cam so that its movement to effect line-feed rocks the lever 29 counterclockwise on its pivot 28, and the stamp 26 prints the symbol on the paper carried by the platen. The transmitter may be operated by a keyboard or perforated tape.

Title: Improvements in and relating to continuously loaded conductors
IPC: H01B13/28
Filed: 1923-06-19
Abstract: 221,753. Felten & Guilleaume Carlswerk Akt.-Ges. June 19, 1923. Addition to 200,497. Annealing.-Relates to a process for producing equal values of self-induction per unit length in the manufactured lengths of continuously-loaded conductors. Use is made of a source of heat that conveys the annealing heat to the conductor from the outside, the source of heat moving relatively to the conductor and being such that only a short portion of the conductor is brought to the annealing temperature at a time. The selfinduction is measured during the annealing, which is interrupted when the desired value is reached. Before annealing the conductor is wound on a drum a in well-defined spirals which do not touch each other. The conductor is then lead over the annealing point b in a regular manner and wound on a second drum c. Alternatively, the conductor is wound on a drum in regular spirals and the source of heat is moved along the longitudinal axis of the drum during the rotation of the latter, in such a manner that the annealing point follows the whole length of the conductor.

Title: Improvements in cathode-ray tube television receivers
IPC: H01J31/12
Filed: 1941-07-26
Abstract: 547,124. Television amplifiers. STANDARD TELEPHONES & CABLES, Ltd. July 26, 1941, No. 9522. Convention date, July 31, 1940. [Classes 40 (iii) and 40 (v)] Relates to television receiving apparatus including a cathode-ray tube in which the ray is focused on a luminescent screen and is modulated by being laterally shifted before passing through an aperture, this modulation being non- linear. According to the invention, this non- linear defect is compensated by distorting the input signal on its way to the modulating device. As shown, the electrodes 26, 27, 26<1>, 27<1> controlling the lateral shift of the ray before it passes through the aperture disc 22 are connected in pairs between one terminal of the signal input and a tapping 39 on the anode resistance r<1>, r<2> of a multi grid thermionic tube 41, to which the signal is also fed. A bias battery 40 is inserted in the lead to the tapping 39, and the various electrodes of the tube 41 are connected and biased as shown so as to produce a variable voltage across the resistance r<1>, r<2> which compensates the non-linear defect of the modulating device of the cathode-ray, thereby giving an overall linear relation between modulation of ray and signal input.

Title: Improvements in or relating to means for operating mercury switches
IPC: H01H29/24
Filed: 1928-03-29
Abstract: 290,597. Soc. Anon. Hewittic, and Demontvignier, M. May 16, 1927, [Convention date]. Addition to 273,257. Thermal switches; mercury switches; protective arrangements. - To enable the thermallyoperated mercury switches of the parent Specification to operate with a substantially constant time limit under varying conditions of supply voltage &c., the heating current for the bimetallic strip is automatically kept substantially constant. This may be effected, as shown in Fig. 1, by inserting in the heating circuit a self-regulating resistance 3, the resistance of which increases quickly with the temperature, in a modification (Fig. 3, not shown), by putting the bimetallic strip and a similar self-regulating resistance in shunt with a normal fixed resistance in the main circuit or, in another modification (Fig. 4, not shown), by putting the bimetallic strip in circuit with the secondary coil of a saturated current transformer the primary of which is in the con-- trol circuit. Fig. 2 shows the application of the invention to a protective system, four thermally operated mercury switches 10 - - 13 being soarranged that, at time intervals, adjustable at will, they successively bring about three attempts at re-closing of a contactor 18 after a break, and if the overload persists, the closing of a circuit to a warning device. When any one of the three switches 10 - - 12 is tilted, circuit between two contacts at the right hand end of the tube is broken and a circuit is momentarily closed between one of these contacts and a third contact at the left hand end, the latter circuit serving in each case to bridge ccntacts 21 which have been opened by the contactor switch 18 and' thereby to energize momentarily the actuating coil 19 of the contactor. The switches 10 - - 13 are operated in succession by current flowing in a circuit 14, the power from which is obtained through a transformer 23, 14, the primary circuit of which is closed at 22 when the contactor 18 is open. The fourth switch 13 serves to close the ' warning ' circuit. A self-adjusting resistance 15- is included as shown, so that the current in the circuit 14 is substantially constant in spite of the variation in resistance produced by the inclusion of one or more of the bimetallic strips 6 - - 9 in the circuit.
