Patent GB-445995-A (GB)
Abstract: 445,995. Control systems for welding- arcs. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 15, 1935, No. 28472. Convention date, Oct. 16, 1934. [Class 38 (iv)] [See also Groups XXXVIII and XI] In a system wherein the supply voltage across a welding arc may be controlled by the welding operator, means are arranged at the operator's position so as to facilitate control over a special conductor and one or other of the welding current supply conductors. As shown, the supply voltage is generated by a generator 10, preferably of the type described in Specification 159,374, [Class 35], having series and shunt fields 13, 11 the former of which is tapped by a switch 15 and the latter is connected through a regulator 12. The regulating equipment is operated by a motor 17, the switch being driven through a Geneva mechanism 28. The motor is controlled for rotation in one direction by a switch 18 mounted on the electrode holder and adapted to close the motor circuit over a control conductor 25 and the welding current lead 5. A reversing circuit for the motor is provided over the conductor 25 and the welding current lead 7 and is completed when an electrode 29 is placed in contact with the work. The electrode 29 is provided with a spring controlled insulating sleeve 31 which telescopes within the sleeve 30 to expose the electrode when the electrode is forced down on the work. The generator is provided with brushes 10, 9, 8, the brushes 10, 9 producing substantially constant voltage while the voltage between the brushes 8, 9 varies according to the condition of the arc. In a modification instead of providing a third brush, a tapped potentiometer connected across a pair of brushes may be employed. Instead of providing control switches on the electrode holder, an independent control means which is accessible to the operator may be employed.

Abstract: 1,272,817. Feeding webs. F.M.C. CORP. 10 Sept., 1969 [17 Sept., 1968], No. 44756/69. Heading B8R. A web unwind stand comprises a frame in which are rotatably mounted a pair of turret arms 62, (61) Fig. 2 (not shown) for supporting a first roll 66 in a position for unwinding a web therefrom in a counter-clockwise sense, as shown, or in a clockwise sense (Fig. 4, not shown) and for supporting a second roll 64 in a standby position, and a plurality of splicing rollers 49, 51, 57 mounted between pivoted brackets 41, (43) for movement between splicing a web unwinding in a counterclockwise sense to a position for splicing a web unwinding in a clockwise sense. As shown, when the running roll 66 approaches exhaustion an operator gives a pull-start to the standby roll 64 so that the leading end of the new web 67, prepared with an adhesive strip 68, drops vertically between the splicing rollers 57, 49 and contacts the expiring web. Pneumatic cylinders 53, (55) are then actuated so that nip pressure is applied to the splice in two places, between rollers 57 and 49, and between rollers 57 and 51. If the running roll has to be unwound in a clockwise sense a lock 45 is disengaged and the brackets 41, (43) are pivoted into a second position where the lock 45 can engage within a hold 47, and the arms 62, (61) are suitably positioned (Fig. 4, not shown) so that the same procedure as described above can be followed when it is desired to make a splice. The unwind stand may form part of an installation (Fig. 1, not shown) including a printing station, a drying oven, and a rewind stand, and it is provided with a control system to maintain the in-feed web tension constant. This tension control system includes first and second pneumatic brakes (75), (76) Fig. 2, (not shown) interconnected with the core shaft of the running roll to apply braking torque thereto under the control of signals derived from a tension sensing dancer roller (22) Figs. 1, 5 and 6 (not shown), the arrangement being such that brakes (75), (76) are both energized at the start of a full roll, but only brake (75) being effective later in the unwinding process. Electric brakes may replace the pneumatic brakes (75), (76) and a load cell type of sensing roller may be used instead of the dancer roller (22).

Filed: 1974-10-16
Abstract: 1462709 Spray drying NIRO ATOMIZER AS 16 Oct 1974 [22 Oct 1973] 44899/74 Heading BIB Powder, from milk or similar liquids, is produced by spray drying in a first stage of rotary atomizer in hot gas to obtain a moist powder which is after-dried in a second stage in hot gas in a fluidised bed to the desired moisture content of the final product while the fine particles carried along are separated from the gas leaving the two stages, the process being characterized by a combination of the following measures: a. The temperature of the hot gas which is supplied to the first stage is at least 10C higher than the highest temperature which would be permissible for the liquid in question if the spray drying for the production of the final product with the moisture content desired were to be performed in only one stage and with the same degree of heat damage, b. the spray drying in the first stage is carried on to a moisture content of the powder obtained from this stage, which, dependently on the liquid to be dried, is 2-15% by weight higher than the desired moisture content in the final product and the highest value of which moisture content is determined with due regard to the fact that agglomeration shall be substantially avoided, and c. the fine particles separated from the gas are added to the main bulk of the powder produced after the latter has been dried to a moisture content of at the most 10% by weight, with due regard to the fact that the fine particles should not stick thereto to such an extent that stable agglomerates are formed.

Abstract: 1,219,277. Radar. DECCA Ltd. 30 Sept., 1968 [3 Oct., 1967], No. 44911/67. Heading H4D. In an airborne Janus-type Doppler system a backward beam is on a frequency sufficiently different from that of a forward beam that signals reflected from areas illuminated by one beam do not significantly affect the signals received from areas illuminated by the other beam; for example, the frequencies may differ by at least the highest expected Doppler frequency. Thus the deleterious of side-lobes is reduced. In an embodiment utilizing three CW beams A, B, C, Fig. 2, beam C is on a different carrier frequency, derived from an oscillator 34, Fig. 3, the difference frequency (10À7 Mc/s.) being used as an I.F. A reference signal at 10À7 Mc/s. is afforded by a mixer 38. Receiving aerials RA, RB, RC, corresponding to the three beams, are provided; signals from aerial RA are heterodyned with signals from frequency multiplier 35 and likewise for aerial RB, aerial RC output being heterodyned with an output from frequency multiplier 31. The outputs of each I.F. amplifier 43, 46, 49 are mixed in mixers 53, 54, 55 with phase-quadrature outputs from mixer 38 and after filtering the mixer outputs are fed to respective tracking loops 59, 60, 61. The extracted Doppler frequencies are fed to circuits 62 to give aircraft velocity in known manner. Circulators, e.g. 32, 36, are included to prevent unwanted frequencies entering the channels.

Title: Data processing system
IPC: G06F15/78
Filed: 1961-12-15
Abstract: 1,002,159. Electronic computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 15, 1961 [Dec. 30, 1960], No. 44962/61. Heading G4A. Associated with a main computer 10 is a so-called input - output processor which is used to correct (up date) functions computed at relatively long intervals of time by computer 10 and required accurately to perform e.g. a control operation during the intervals. The input-output processor consists of: a magnetic drum (100) (called storage means 14 in Fig. 1) on which are three tracks: a delta track (106), a quantity track (105) and a transfer track (104); an adder-subtractor 17; and an input mixer 18 (or circuit). The last computed value of the function occupies one word location on the quantity track and its expected increment is stored in a corresponding location on the delta track. On each revolution of the drum the delta and quantity words are combined in adder-subtractor 17 and read back to the transfer track. This track is merely a device to delay writing into the quantity track until the appropriate word location is under the quantity track head, and may be replaced by a delay in a line between the quantity track write head and the adder, or obviated if the adder is synchronized with drum rotation. The last operation is to write the incremented quantity into the quantity track. The output of the adder subtractor is, in the application shown, input to an error generator (a subtractor) where it is compared with a digital representation of the positions of a shaft, the error signal controlling the shaft motors. To determine the value to be entered on the delta track the two last computed values of the function are differenced and the result divided by the number of drum revolutions. A second function of the input-output processor is the provision of accurately timed pulses. A specific value is entered on the delta track with the quantity track blank. The delta track is added into the quantity track until there occurs overflow. The overflow bit is sent to circuits 24 as the required pulse. Variations in the delta value due to external events are recorded on a counter 35 and share the same line to adder 17. The adder is controlled by the sign of the delta quantity as sensed by circuit 19. Delta length control 38 increases the value in a word on the delta track by storing overflow from the previous delta word and entering it at the first bit time of the next addition on to the adder. Means may also be provided for shifting the delta value in a word so as to increase or decrease its magnitude. Specifications 844,308 and 861,688 are referred to.

Abstract: 1443008 Isomerizing hydrocarbons; catalyst for cracking hydrocarbons UOP Inc 27 Sept 1973 [28 Sept 1972 (3)] 45278/73 Heading C5E [Also in Division B1] Hydrocarbon feeds are converted, e.g. hydrocracked, hydrotreated and, in particular, isomerized in contact with a catalyst formed by reacting an alumina composite containing 0À1 to 5% wt. of a platinum group metal or nickel firstly with a Friedel-Crafts metal halide then, in a non-reducing atmosphere at 100-600 C., with a polyhalo compound which contains at least two halogen atoms on the same carbon or sulphur atom or is a boron trihalide. The isomerization may be effected at 65-235 C., a pressure of 1 to 140 atmos., a LHSV of 0À5 to 10 and a hydrogen to hydrocarbon mole ratio of 0À25 :1 to 20 : 1. The feed may be a C 4 -C 8  straight chain paraffin hydrocarbon, 2- or 3- methylpentane (to give 2,2- and 2,3-dimethylbutane) or a naphthene, e.g. dimethylcyclopentane (to give methylcyclohexane) or methylcyclopentane to cyclohexane. The Examples describe the isomerization of butane and of a mixed n-pentane/n-hexane feed to give isopentane and 2,2-dimethylbutane. Catalysts containing nickel as the Group VIII metal are suited to C 4  isomerization but not C 5  isomerization. The use of the catalyst for hydrocracking of heavy oils to form petroleum and LPG at up to 300 C. and a pressure of 5 to 70 atm. is also mentioned.

Abstract: 1482706 Spacial filtering DYNELL ELECTRONICS CORP 21 Oct 1974 [2 Nov 1973] 45472/74 Headings G2A and G2J [Also in Division H4]  Three-dimensional information defining an object surface is generated by successively irradiating the object 10, Fig. 1, via a plurality of masks 28a-28d, Fig. 2, on a mask strip 24, the resulting images being photographed on film 20 as successive frames 34a-d, Fig. 3, which are placed between associated light sources 36a-d and sensors  38a-d mounted on a scanning mechanism 40 so that for each point, such as Pi on the object  surface in addition to the x and y position coordinate data a digital pulse pattern such as 1010 is generated providing indication of the order in the record succession of those records which include point P 1 . From these signals the spatial positioning of each point may be determined and the surface of the object reproduced in three-dimensions. Instead of recording separate frames 34a-d for each of the masks 28a-28d, irradiating radiation at different frequencies may be used e.g. the clear and opaque segments of masks 28c may be replaced by different colour filters and the exposed colour film analyzed using colour sensitive sensors. Since the signals derived-by the sensors 38a-38d will exhibit overlap due to light dispersion, signals for gating the outputs of the sensors may be derived from the sensor output signals Figs. 5-7 (not shown). The configurations of masks 28d-28f may be produced by moving mask 28c successively vertically. The projector-mask combination may be effected by projection  cathode ray tubes suitably excited to define the operative projection field.
