Title: Improvements in or relating to apparatus for the development of photographic prints
IPC: B23F5/20
Filed: 1935-08-21
Abstract: 445,235. Photographic developing- apparatus. KALLE & CO. AKT.-GES., 23, Rheinstrasse, Biebrich-on-Rhine, Germany. Aug. 21, 1935, No. 23529. Convention date, Nov. 6, 1934. [Class 98 (ii)] Apparatus for the development of photographic prints by gas, especially ammonia gas, consists of a developing chamber containing a driven roller, a perforated or inter. rupted stationary guide surrounding the roller at a small distance and extending from the point where the prints are received by the roller to the point where they are discharged, and one or more rollers, for example, disc rollers, penetrating the interruptions in the guide and bearing under spring pressure on the driven roller. In the form shown, the driven roller 2 is mounted in the chamber 1 and is surrounded by the wire guide 3 and pressing rollers 5. Heating elements 13 are arranged in the chamber 1 and the inlet and outlet passages a, b are provided with metal strips 7, 9 for preventing escape of gas, which is either generated in a heated gutter 15 or blown onto the prints by pipes 17. A driven roller 8 engages the roller 2 at the outlet passage and the prints on emerging enter a passage 11 containing heaters 18 and through which air is drawn by a fan 19. The pressing rollers 5 are in the form of parallel discs bearing on the roller 2 between the wires of the guide 3.

Title: Improvements in or relating to remote controlled selecting arrangements
IPC: G01N23/22
Filed: 1944-11-27
Abstract: 586,182. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and RATTUE, E. A. Nov. 27, 1944, No. 23605. [Class 40 (v)] In a wireless communication system comprising a transmitting station and a number of receiving stations, selection of any one receiving station is made in response to the transmission of signals comprising trains of pulses alternately of two different carrier frequencies and which are keyed in a manner characteristic of the station to be selected. The transmitter oscillator 2 operates on one of two adjacent frequencies (e.g. 2.002 and 2.004 Mcs. /sec.) determined by the piezoelectric crystals 5, 6 connected to the opposite contacts 11, 12 of the relay contact assembly 8. Operation of the dialling means 10, interrupting the energizing circuit of the relay 9, causes a predetermined number of reversals of the contacts 8, and the transmission of a corresponding series of R.F. pulses, alternate pulses being of the alternative carrier frequencies. In the receiver, the amplified R.F. pulses are passed to a mixing valve 16 whose oscillator section operates at a third adjacent frequency (e.g. 2.000 Mcs./sec.) determined by the piezoelectric crystal 17. The resultant A.F. pulses (i.e. 2 kcs. and 4 kcs.) are separated by means of crystal filters 18, 19 and applied to the control grids of the twin detector valve 20, 21. The rectified D.C. pulses in the anode circuits are applied to the opposing windings 22, 23 of a relay 24, successive pulses thus causing alternate reversals of the relay contacts 25. The resultant energizing of the selector-unit windings 28 causes stepped operation of the ratchetwheel 32. Transmission of the correct digit trains of pulses causes the wheel 32 to be latched after each train, the final position taken up completing the circuit 33 and energizing the relay 34. Energization of the relay 34 closes the locking contacts 35 and also closes contacts 36 to ring the alarm bell 37. An interrupter key 38 may be provided for release of the locking circuit, and known means may be employed for returning the selector mechanism 32 to normal.

Title: Improvements in or relating to polishing machines for sliding-clasp fasteners
IPC: B24B19/00
Filed: 1953-08-28
Abstract: 721,130. Polishing sliding-clasp fastener elements. NAGELE, K. F. Aug. 28, 1953 [Aug. 29, 1952], No. 23821/53. Class 60 A machine for polishing sliding-clasp fastener elements secured on a continuous beaded type in groups separated by portions of tape to which elements are not secured, comprises two brushes 3, 4 of fine steel wire, rotated in opposite directions by a motor 2. The tape 7 is fed through the machine by rolls 6 also driven by the motor 2 and is kept taut by a brake 12. The tape passes over deflector guides 10, 11 associated with the brakes and comprising fixed studs 13 or rollers rotatably mounted on studs. Each deflector stud has an annular groove 14 which only partially accommodates a fastener element 15 so that it projects therefrom and is treated by a brush. When a portion of tape 16 free from fastener elements is passing over the deflector guide, the beaded portion lies wholly in the groove and is not treated by the brush. A blower 8 driven by the motor 2 withdraws dust-laden air from inside the machine and passes it through a filter 9. The brushes 3, 4 are carried by bearing supports 17, 18, adjustably fixed by locking screws 20, to a shaft 19 which is oscillated by an arm 21 on the shaft held by spring means against a cam disc rotated through pulley 22 by the motor 2. Alternatively, the reciprocation of the brushes is effected through a bell crank 25, 26 by two pulleys 27, 28 driven with equal circumferential velocity but having different diameters so that their rates of rotation differ. The opposed hubs of the pulleys are inclined obliquely to the pin 29 on which they are mounted.

Title: Improvements in or relating to electric circuit arrangements
IPC: H04Q3/00
Filed: 1967-05-23
Abstract: 1,149,316. Automatic exchange systems. SIEMENS A.G. 23 May, 1967 [24 May, 1966], No. 23857/67. Addition to 1,086,576. Heading H4K. The line finder of the parent Specification is modified for. the case where there are a large number (e.g. 100 or 1000) of lines. The appearances of the lines are arranged in matrix form, as for the 100-line case shown. An input marking on line appearance 23 say, causes stage EZ2 of the ring-like tens allotter ZK (which forms the bases of the parent Specification) to be marked via an OR gate MGZ2 associated with all the appearances having a tens digit value of 2. An output from the marked stage EZ2 is applied to the AND gates KG20-KG29 associated with the appearances of tens digit value 2. In this instance gate KG23 only opens so as to mark stage EE3 of the units allotter EK via OR gate MGE3 associated with the appearances having a units digit value of 3. The outputs from ZK and EK correspond to the address of the marked line appearance. When the two allotters have each produced an output in response to the input marking, a pulse from a reset pulse generator resets allotter EK. An output just-reset pulse from EK in conjunction with a pulse from the generator. then resets the higher-order allotter ZK. In addition the setting of ZK in response to an input marking produces a pulse which automatically resets the lower-order allotter EK to provide a " doublecheck " that EK is reset before an input marking is applied to it (Fig. 4, not shown). An extension of the system to a 1000-line system using three allotters (corresponding to hundreds, tens and units digit places) is described with reference to Fig. 2 (not shown). Fig. 3 (not shown) depicts a simplified 1000-line system which requires less AND gates of gates KG00- KG99 in Fig. 1, than the Fig. 2 system. A schematic of the Fig. 2 arrangement together with the reset arrangement of Fig. 4 is depicted in Fig. 5 (not shown).

Title: Process of producing pig iron
IPC: C21B5/02
Filed: 1946-08-13
Abstract: Pig iron containing 1-4 per cent silicon, 0.25-1.0 per cent titanium, and of improved fine graphite structure is produced in a blast furnace by charging with iron ore, a titanium bearing material (e.g. ilmenite, rutile, sludge waste from the electrolytic reduction of bauxite), limestone, sufficient coke to reduce the oxides present, and if necessary silica-bearing material; regulating the proportions of the constituents of the charge to maintain a slag volume of 1000-1500 pounds of slag per ton of iron produced, and to produce a basic slag containing in excess of 42 per cent (preferably 44-48 per cent) combined CaO and MgO; and smelting the charge using air temperatures greater than 1250 DEG F.  The preferred amount of titanium in the pig is 0.4-0.5 per cent, whilst the preferred air blast temperature is between 1500-1600 DEG F.  The pig iron so produced is said to be a heavy scrap carrier and to be particularly suitable for the production of easily machinable castings.

Filed: 1950-10-02
Abstract: 684,523. Automatic pressure control systems. SMOOT, C. H. Oct. 2, 1950, No. 24022/50. Class 38 (iv). In a servo-operated system for controlling a slow responding variable, a servo displacement signal is opposed by a reset signal to maintain the variable condition at a set value. As shown, the pressure of fluid flowing up a pipe 10 is detected by a device 13 and controlled by a valve 11. The signal voltage from a detectoractuated potentiometer 16 is opposed by a voltage from a transformer 18 to give zero error voltage at the required setting. The error voltage applied to amplifier 29 controls a twophase reversible servomotor 26 actuating the valve 11 and having a velocity feedback from a generator 32 and a displacement feedback from a potentiometer 34. A similar servomotor 36 controlled by the error signal is arranged to operate a potentiometer 45 at the rate at which the pressure is restored after the valve 11 moves, the voltage from potentiometer 45 being introduced through transformer 46 into the control circuit in opposition to the displacement voltage from potentiometer 34 whereby the system is maintained in balance at the required setting. The control voltage for the resetting servomotor may be taken from the response adjustment potentiometer 24, and the reset voltage introduced between the velocity feedback generator 32 and the amplifier 29, Fig. 2 (not shown).

Title: Improvements in and relating to semiconductor devices having coupled bistable elements
IPC: H01L29/00
Filed: 1969-05-14
Abstract: 1,263,622. Bi-stable transistor circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 May, 1969 [17 May, 1968], No. 24529/69. Heading H3T. [Also in Divisions G4 and H1] Bi-stable semi-conductor devices are coupled by intermediate semi-conductor regions which include a "conductivity modulation" region receiving minority carriers drained from an accumulation region of the preceding bi-stable device and connected to the accumulation region of the next device. In the shift register shown, if a first thyristor 1 is conductive, lowering the terminal 36 to a negative voltage causes the upper base of a double base diode to become negative and thus the emitter 17 to become conductive. Minority carriers thus drain from the accumulation region adjacent the gate of the thyristor and switch the thyristor off. The carriers transferred to the conductivity modulation region of the double base diode allow the latter to conduct when the voltage at 36 is restored and this either fires the next thyristor or confirms its conductive condition. If thyristor had initially been off, the double base diode would not have fired thyristor 2 and if it were on the action of the second double base diode 2 would have switched it off. Diodes 21 and 25 prevent false operation due to reverse currents. In Fig. 2 (not shown), the thyristors are replaced by four-electrode double base diodes, the emitter electrodes being connected to the upper base by a diode (not shown) to provide a low resistance path during the shift pulse and thus to prevent false firing. The connection (67) corresponding to 16 may be a hook collector. The circuit may be made in integrated circuit form and it is stated that some of the connections could be in point contact form. It is also stated that the invention could be applied to a ring counter.
