Title: An improved method of and apparatus for producing twisted artificial silk from cuprammonium cellulose solutions according to the wet stretch-spinning process
IPC: D01D5/14
Filed: 1926-10-01
Abstract: 260,564. Bemberg Akt.-Ges., J. P. Nov. 2, 1925, [Convention date]. Apparatus for making filaments; ammoniacalcopper cellulose solutions, processes for making filaments from.-To enable threads of artificial silk obtained by the cuprammonia stretch-spinning process to be collected in centrifugal boxes, the threads, after leaving the spinning apparatus, are led over suitable guiding devices and are acidified during their passage in suchwise that the acidification process is completed by the time the threads reach the collecting apparatus. The guiding devices may consist of positively driven guide rollers, which may be smooth, ribbed or serrated and may be used in conjunction with the usual guide channels, rods, and tension rollers. Thus, the thread may pass from a spinning apparatus 1. Fig. 1, into an acid bath 6, being guided therein by a rod 3 and a tension roller 5, and thence may be led up to and over or wrapped round a positively driven roller 7 before falling into a centrifugal box 8. Instead of a bath 6, the threads may run over an horizontal or inclined gutter 6, Fig. 2, on to which dilute acid falls. In both forms, the tension roller 5 may be omitted, and the acid solution may be applied at the delivery roller 7. preferably in such a manner that acid runs back along the thread. It is preferred, however, to employ a guide rod or tension roller in advance of the delivery roller, since by this arrangement the threads can be placed under tension during the acid treatment.

Filed: 1925-09-30
Abstract: 240,848. Telefunken Ges f³r Drahtlose Telegraphie. Oct. 1, 1924, [Convention date]. Thermionic generators. - In order to avoid the necessity for alterations of the back coupling when the wave-length of the oscillator is varied, the grid coil is tightly coupled to a coil which is subjected to the oscillatory plate voltage but does not form part of the main oscillatory circuit. As shown in Fig. 1, the grid coil h forms the secondary coil of a transformer, the primary g of which is connected between the points x, y subject to the plate oscillatory voltage. The oscillatory circuit b, c may have tappings p, q for varying the plate connection and the tuning respectively. A block condenser d and a high-frequency choke e are provided as usual. In a further modification shown in Fig. 3, the choke is in two halves g<1>, g<2> forming jointly the primary winding of a transformer, the secondary h being in the grid circuit. The connection to the oscillaaory circuit b, c is taken from a point between the two halves g<1>, g<2>. The Specification as open to inspection under Sect. 91 (3) (a) refers to an arrangement in which the grid coil h is tightly coupled to the choke e, and the additional coil g is omitted. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to electric motor control systems
Inventor: DOLAN HARRY
IPC: H02P3/24
Filed: 1952-09-30
Abstract: 733,869. Control of A.C. motors. ENGLISH ELECTRIC CO., Ltd. Sept. 25, 1953 [Sept. 30, 1952], No. 24426/52. Class 38 (3). A slip-ring induction motor 10 has one phase of the stator winding 10b supplied from a substantially constant voltage source 17 of directcurrent for dynamic braking whilst the other two phases are supplied from a source 18 the voltage of which is varied in accordance with the rotor current of the motor. The induction motor drives a mine winder, and, assuming the winder to be at rest with one cage at a bank, closure of a push-button SB energizes a forward contactor F to connect the stator of the motor to the three-phase supply 12 and release the mechanical brakes. If, during the wind, a negative torque is required to maintain the desired speed, contacts EBI are automatically operated to open the contactor F and contacts EB2 close after a time delay to energize the dynamic braking relay B (provided that the source 17 has not failed). On the other hand, if the direct-current supply has failed, a relay DBF opens contacts DBF1, and the automatic opening of contacts EB3 when negative torque is required causes the de-energization of relay X. Contacts XI open to isolate contactor B and contacts X2, X3 close to complete a circuit to reverse contactor R so introducing countercurrent braking in place of dynamic braking. Near the end of the wind, the limit switch LSE opens to de-energize contactor R which opens contacts R3 to isolate no-volt coil 14 and trip circuit-breaker 13. Manually controlled switch means DBS1, DBS2, are adapted to render the relay X and coil 14 independent of the operation of the relay DBF whereby countercurrent braking may always be introduced when the contacts EB3 open. If thesupply 17 fails with the motor already connected for dynamic braking, the relay X is de-energized by the opening of contacts DBF1 so that contactor B is opened and contactor R closed, as before. If negative torque is not required during the wind then, even if the supply 17 fails, the contactor F remains closed until the limit switch LSB opens. A winder-operated switch TS is arranged to open the circuit-breaker and apply emergency braking if, with dynamic braking in operation, the supply 17 should fail near the end of the wind, or, if the directcurrent has already failed, the contacts EB1 are operated near the end of the wind. Specification 715,583 is referred to.

Abstract: 851,697. Uses of luminescence. NATIONAL CASH REGISTER CO. July 16, 1959 [July 23, 1958], No. 24457/59. Class 39(1). A luminescent device comprises a rigid foraminous sheet 24, Fig. 3, each foramen extending from face to face of the sheet and containing a luminophore 34 responsive to radiation directed through the foramen and containing sealing means 32 to insulate the luminophore from the ambient environmet. The incident radiation may be ultraviolet, light, X-rays or cathode rays and the luminophore may be such that it is excited by one incident radiation and quenched by another thereby providing a bistable storage element. The device may be mounted in or on the face plate of a cathode ray tube and scanned by the beam in order to write in and read out data. Each foramen may also contain a photoelectronic material of the kind described in Specification 845,939 which exhibits two stable colour states dependent as the presence or otherwise of incident radiation from the luminophore. The data stored by this means may be read out by photocells sensitive to the two colour states, which calls may be individual to each foramen or in the case of a scanned device, common to the whole sheet. The luminophore may comprise two phosphor in order to provide the necessary radiation to energise the photochromic material. The device may also be used to investigate phosphor properties by locating such phosphor on each foramen to be excited by the luminophore. In the device shown in Fig. 10 the luminophore 90 comprises phosphors emitting blue and red light when excited by an electron beam and the device is used to read out data stored in a red transmissive colour transparency 92, the data being represented thereon by blue opaque or blue transmissive squares, Fig. 9, in conjunction with a timing record comprising a colour transparency having a regular pattern of red opaque and red transmissive squares 91, Fig. 8. Scanning of such a device and reception of the coloured output on photocells R, 96 and B, 97 produces the data and clock signals shown.

Filed: 1925-10-02
Abstract: 240,860. Pouchain, A. Oct. 3, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Electrodes: separators; supports for electrodes. -In a zinc-lead storage battery the lead parts, particularly the supports for the active material of the positive electrodes, are made of pure lead instead of an alloy of lead and antimony. The reduced mechanical resistance which results is compensated for by providing the positive electrodes with ebonite &c. frames 2 which may be formed with feet 3 as shown in Fig. 1. Instead of a separate frame for each of the electrodes, the latter together with the separators may be held in comb-like members 6 as shown in Fig. 3. The members 6 may be formed by making slots in the walls of the container, or they may consist of horizontal plates having recesses to receive the electrodes and separators. Fig. 4 shows a further method of supporting the electrodes and separators. The positive electrodes 1 and negative electrodes 4 are separated by ebonite &c. frames 5<1> enclosed between wood separators (not shown). The parts are clamped together by bolts and nuts 7. To prevent short-circuiting the negative electrodes 4 do not reach the upper bolts 7 and the positive electrodes do not reach the lower bolts. Additional bolts may pass through the central portions of the electrodes and separators.

Title: Process for the manufacture of butyraldehyde
Filed: 1951-10-23
Abstract: Butyraldehyde is manufactured by a continuous process in which hydrogen is reacted with liquid crotonaldehyde under pressure and at a raised temperature in the presence of an aqueous phase and a hydrogenation catalyst, the liquid crotonaldehyde being introduced simultaneously with the hydrogen and the catalyst, and the catalyst being added as an aqueous suspension.  Small quantities of an emulsifying agent may be added and the hydrogen is preferably used in excess.  To obtain a good yield the hydrogenation should be conducted at a pH value of between 6.9 and 8.0.  The required pH is obtained by the addition of both a carbonate and a hydroxide of an alkali or alkaline earth metal, e.g. of calcium, magnesium, sodium or potassium.  Known hydrogenation catalysts may be used, e.g. nickel and cobalt catalysts and copper chromite.  They may be supported on carriers, for example, on pumice powder or kieselguhr and may be activated, for example, by Cr2O3, Al2O3, ZnO or SiO2.  Suitable emulsifying agents are soap or fatty acid condensation products.
