Title: Apparatus for removing solid impurities particularly rust insoluble in a fluid flow from a fluid flow passing through a circuit
IPC: F28B9/04
Filed: 1975-05-05
Abstract: 1505586 Filters in steam condenser MASCHINENFABRIK AUGSBURG - NURNBERG AG 5 May 1975 [8 May 1974] 18687/75 Heading BID [Also in Division F4] Filter units are provided in or adjacent cooling tubes 2 of a steam condenser 1 (Fig. 4), connected for example to a steam turbine 16, to filter the secondary water which circulates round a closed circuit through tubes 2 and a dry cooling tower 17, 18. Condenser 1 may include one or more banks of tubes 2 connected in parallel and series, with filter units fitted to some or all tubes in each bank. Filter units may decrease in porosity in the direction of flow. Each filter unit may comprise a rigid self-supporting filter or a flexible filter 9 supported within a cage 8 (Fig. 2). By closing the inlet and outlet sides of the condenser and opening drainage and venting lines (15, 14, Fig. 1 not shown), the condenser may be drained under gravity, thus reversing the flow through the filter units. Such reversal may invert each filter 9 to a position inside a secondary support cage 13 and clean the filter for re-use. Alternatively flow reversal may overcome the pressure applied by ribs 32 of cages 8 to the tube interiors to displace the filter units permanently from their positions in tubes 2. This enables filter units to clean the rust particles from the circuit shortly after installation, after which the units are not necessary so they are removed and no longer impede coolant flow.

Title: Improvements in and relating to methods of regulating vapour electric convertors and the like apparatus
IPC: H02M1/04
Filed: 1935-07-04
Abstract: 461,003. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. July 4, 1935, No. 19150. Convention date, July 4, 1934. [Class 38 (ii)] In a polyphase rectifier, inverter, or frequency changer comprising a plurality of arc discharge paths arranged to be initiated in sequence to transmit power between supply and load circuits and wherein the amount of power transmitted is controlled by delaying ignition, the arrangement is such that ignition at the various anodes is delayed by unequal amounts in order to retain a good power factor when a limited amount of power is being transmitted. Thermal conditions at the various anodes are equalized over a number of cycles by changing the order in which the anodes are subjected to delay. For example, in the Figure where the anode voltages for a three-phase arrangement are represented by curves 1, 2, 3, their conducting periods being represented by thick lines, first the anode 3 is delayed, then the anode 2, next anode 1 and so on for a given amount of power transmitted. For smaller amounts of power, one anode is completely suppressed and another progressively delayed, the order in which the control voltages are distributed being changed each cycle. This may be effected, e.g. by supplying A.C. potentials to control grids at half the frequency of the anode voltages but of reversed phase rotation, or by supplying voltage impulses to the grids through synchronously-driven rotary distributers. Reference has been directed by the Comptroller to Specifications 398,364, 400,635, and 401,404.

[Also in Groups XXXVI, XL (b) and XL (c)] In the assembly of an article of electronic apparatus, such as a television or radio receiver, comprising components supported between two parallel insulating plates carrying printed wiring by the insertion of their terminal leads into notches, connecting with the printed wiring, formed in the peripheries of the plates, the components may be contained in a hopper from which they are taken in the correct sequence and placed on a moving belt which conveys them to a point from which they are inserted automatically into the circuit. The insulating plates are supported in a rotatable holder and the components to be mounted between the plates are contained in a rotatable hopper in the order in which they are to be inserted in the equipment. An operator picks the components out one at a time and places them on the conveyer belt, his hand interrupting a beam of light shining on a photo-electric cell each time he does so and causing the plates to be rotated through an angle corresponding to one notch and the conveyer belt to move a corresponding distance forward. On reaching the end of the belt, the component runs down a shoot whence it is delivered into the appropriate notches on the panels. Between each movement of the panels a double soldering-iron assembly is applied automatically at a point which is a predetermined distance round the plates from the end of the shoot to solder the component at that point to the printed wiring.

Title: Improvements in or relating to differential locking devices
Inventor: BENNETT WILLIAM ALFRED
IPC: F16H48/30
Filed: 1962-05-18
Abstract: 958,460. Differential gear and control. FORD MOTOR CO. Ltd. Feb. 13, 1963 [May 18, 1962], No. 19318/62. Heading F2D. [Also in Division B7] An hydraulically operated differential lock is released when the steerable wheels are turned by more than a predetermined amount from the straight ahead position (see Division B7) by connecting conduit 27 to an hydraulic reservoir instead of to the outlet 37 of an hydraulic pump. An overriding manual control 41 may release the differential lock by connecting the pump outlet 37 directly with the reservoir. The differential look comprises a piston 29 slidable in a bore in axle casing 43, splined at 47 to extension 46 of the bevel gear on axle shaft 59 and having dogteeth 55 which are engageable with corresponding teeth on coupler 53, which is itself connected by dog teeth to differential carrier 54, to lock the differential. The dog teeth 55 engage the coupler 53 when pressure hydraulic fluid is supplied through conduit 27 to annulus 28 and the piston moves axially against the pressure of spring 50. Release of the hydraulic pressure allows the spring 50 to disengage the dog teeth 55 and hence the differential lock. The hydraulic pressure in conduit 27 is controlled by cam surface 10 of rocker shaft 8 and in the straight ahead position shown in Fig. 1 pressure fluid from pump 36 passes through annuli 34 and 20 of spool control valve 1 and acts on the larger side of differential area head 61 of valve 18 so that pressure fluid conduit 31 is connected to conduit 27 engaging the differential lock. When rocker shaft 8 is rotated and valve spool 9 displaced to the left the upper side of head 61 is connected to the reservoir through annuli 20 and 35 allowing the pressure fluid in conduit 22 acting on the smaller side of head 61 to raise the valve spool and connect conduit 27 through valve 18 with the reservoir so permitting spring 50 to disengage the differential lock.

Abstract: <PICT:0596525/III/1> <PICT:0596525/III/2> <PICT:0596525/III/3> <PICT:0596525/III/4> Gum or a similar substance is removed from or applied to a flat horizontal surface such as the top of a table for screen printing by means of an apparatus which comprises a plurality of independently mounted and self-levelling blades resting on the surface and pressed resiliently thereon, and carried on bars extending across the surface and mounted on a carriage also carrying a gum container, the carriage being mounted on rails on the table or other surface so that it can traverse the table from end to end. Referring to the Figure, a table 8 has rails 9 at both sides, on which wheels 10, mounted on carriage 11, run. Mounted on carriage 11 are cross members 12 in front of which are parallel flat cross members 13 each having a handle 14 at each end so that members 13 may be turned parallel or at right angles to the table.  Arms 15 are slidably fixed in sockets 16 turnable on members 12.  At the end of arm 15 are a pair of cylinders 17 on short arm 15a, Fig. 4 and 6, having springs 18 surrounding rods 19 and pressing on shoulders thereof nuts 20 regulating this pressure, while at the foot of rods 19 are blades 19a.  The adjustment of nuts 20 allows the blade edge to be set at the efficient working angle.  Arms 15 rest on members 13 so that by turning handle 14 the arms can be tilted off table 8 or can be brought to rest thereon under their own weight.  At the front of carriage 8 is mounted tank 21 having wheels 22 running on rails 23 and having a delivery opening 24 controlled by valve 25 to run liquid on to the table.  At the other end of the machine are pivoted arms 26 with slots 27 and rachets 28 with which pawls 29 cooperate to hold down on the table a roller 30 on which is wound a length of cloth. Gum is removed from the table by moving the apparatus along the table with the front and back blades down (by lowering cross members 13) and supplying water to this table when the blades scrape off the old gum.  The carriage is then returned to the starting end, the roll of cloth mounted in slots 27 of arms 26, which are pulled down to press cloth on table, handle 25 turned to allow gum to flow on to the table, and the carriage moved along the table.  As the gum flows on to the table front blades 19a push it in front of them leaving a gum coating which is smoothed off and spread thinly by the rear set of blades so that the cloth from roller 30 coming along behind is gummed evenly and smoothly to the table.
