Patent GB-1438384-A (GB)
IPC: A63F7/02
Filed: 1973-06-11
Abstract: 1438384 Pin table obstacle BALLY MFG CORP 11 June 1973 [5 Sept 1972] 27745/73 Heading A6H [Also in Division H1] A ball bumper with electric switch means has a ball-engaging target member 16 with a stem 15 projecting through the table 13 and yieldingly held in a normal centralised position by a spring 17 in which position the free end 15A of the stem overlies a button 32 attached to the free end of a spring contact blade 31 and the blade is biassed for movement towards the free end of a spring contact blade 31 and the blade is biassed for movement towards the stem but is held by holding means comprising a land surface of the button 32 being in engagement with the free end of the stem. A contact 34 on the blade 31 cooperates with another contact 35 on a blade 33 and constitutes a 'bumper switch' 30 which is actuated when a ball strikes the target member 16 and causes displacement of the stem beyond a margin of the land surface and in such displaced position the holding means blocks the return of the stem so that the 'bumper switch' remains actuated until reset. In the embodiment described a ball reprojecting means is shown as comprising a metal ring 18 supported on two rods 19 passing through the table for attachment to a carrier plate 21 forming part of the upper end of a plunger 22 of a solenoid 24 and which is drawn sharply downwards against a restoring opening 23 when the solenoid is energised. Also attached to the solenoid structure is a movable resetting bracket 60 which has a central opening to accept the free end of the spring contact blade 31 and there is a 'breaker switch' 50 formed by two cooperating contact blade springs 51, 52, the latter having an extended end 52A which is engaged by an insulating washer 29 carried by the plunger for opening the switch contacts 51X, 52X when the solenoid is energised. In Fig. 1 the 'bumper switch' 30, the 'breaker switch' 50, and the solenoid coil 24 are connected in series with a source of electrical supply 37 so that ball actuation of the 'bumper switch' 30 energises the solenoid which then causes reprojecting means 18 to function and actuates the resetting of the 'bumper switch'. Various alternative and additional electrical circuit and score or control arrangements associated with ball bumper games are described including independent control for resetting the 'bumper switch' 30, and selective holding means with directional approach or reprojection characteristics as further game hazards can be introduced by using shaped stem engaging button members (Figs. 4, 4A, not shown).

Abstract: 1,179,740. Superconductor magnets. HITACHI Ltd. 16 June, 1967 [22 June, 1966], No. 27836/67. Heading H1P. A super-conductor coil comprises a plurality of sections each of which is supplied with a current less than its critical current in the magnetic field to which it is subjected. In an embodiment, each of the legs 11 of a pair of saddle shaped coils, Fig. 4, is constructed of three sections, the innermost section carrying the least current and the outermost section carrying the most current since they are subjected respectively to the highest and lowest magnetic fields. The three sections are connected in series to a single power supply, the currents through the middle and inner sections being reduced by by-passing some of the current through variable resistors. Fig. 10 (not shown). The legs of the coils can be wound to an arcuate cross-section. Fig. 7 (not shown), to reduce the size of the coil. Other ways of subdividing the legs and the bridging sections (12) are described, Figs. 6 and 8 (not shown). Circuits for supplying a large number of winding sections with different currents are also described. Figs. 13 and 14 (not shown). Each of the coil sections may be bridged by a super-conductor switch so that when the required currents have been established, the coil can be switched to the persistent current mode, Fig. 15 (not shown).

Title: Photographic cameras
IPC: G03B17/00
Filed: 1973-06-12
Abstract: 1433814 Cameras FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 12 June 1973 [19 Aug 1972] 27913/73 Heading G2A A camera has a central electronic control system comprising a step-by-step switch I arranged to sequentially initiate operation of various camera elements (e.g. diaphragm closing, mirror hinging, shutter opening) and responsive to a programme and control unit II into which are fed actual valve signals generated in response to the state of some of the elements and the state of manually operated elements (e.g. camera release member 27 multiple exposure selector 1). As shown operation of the camera release 27, causes the unit II to actuate a generator IIIa which switches switch I sequentially from steps zero to three during which the outputs 31 from switch I initiate light measurement by unit IV and corresponding adjustment of the diaphragm 10, 11 which also depends on the manually set film and shutter speed controls VIII, VI. In Fig. 2 (not shown), the shutter is controlled automatically, and film speed and diaphragm aperture are set in manually if a release block 16 is actuated unit II prevents further switching. Otherwise generator IIIa switches switch I to step four to close the shutter 14, five to hinge up the mirror 13 and open a protective shutter 3, six to open the shutter and energize a generator IIIb which compensates for battery voltage loss, and seven to energize an exposure timer IIIc (a monostable flip-flop, (35), Fig. 4 (not shown), de-energizing the shutter opening windings after a certain time in the case of long exposures) and via unit II to switch off generators IIIa, IIIb. Generator IIIc then switches switch I to step eight to close the shutter, generator IIIa is turned on to switch to step nine to operate the film wind 5, return the mirror and protective shutter and turn IIIa off again. When the mirror has returned unit II switches on generator IIIa and switch I is stepped sequentially from ten to fifteen to close the shutter, open the diaphragm and switch off the power. Pressing a measurement key 26 steps switch II from 0 to 3 to measure and indicate diaphragm value, Y adjustment of units VI or VIII is made switch I is returned to zero by unit II via lead 12. Y both key 26 and release 27 are pressed switch I is switched straight to step four to begin exposure. Multiple exposures Unit II receives an input 1 indicating selection of multiple exposures. Depressing release 27 above causes the whole programme, steps 1-14, to be carried out repeatedly i.e. the diaphragm is set afresh for each exposure. Depressing release 27 and measurement key 27 omits steps 1-3 i.e. the exposure pro-  gramme is carried out repeatedly with the same aperture. Depressing key 26 alone causes only steps 0-3 to be carried out. The photo-electric measurement system can be disabled for both single and multiple exposures; the exposure programme carried out again depending on whether one or both of release 27 and measurement key 26 are depressed.

Title: Improvements in or relating to steam power plants
IPC: F01K7/40
Filed: 1930-09-19
Abstract: 362,547. Feedwater supply systems for steam boilers. ROE, R. C., 167, Rockwood Place, Englewood, New Jersey, U.S.A. Sept. 19, 1930, No. 28079. Convention date, Oct. 12, 1929. [Classes 64 (i) and 123 (ii).] Feedwater is heated in stages by direct contact with steam bled from a number of points in a turbine of variable load. The steam power plant comprises a high-pressure steam generator 10, direct contact feedwater heaters 28 .. 32, bleed conduits 33 .. 37 connecting the heaters with points of different pressure in the turbine 12, centrifugal pumps 40, 43, 46, 52, 57 for pumping the feedwater successively through the heaters in the order of increasing pressure, and electric motors 48, 69 for driving the pumps. The flow and pressure characteristics of the pump and turbine are coordinated for different loads. The operations of the pumps and turbine, and of the load and feedwater heating are interrelated. The condensate from condenser flows to a hot-well 38 from which it passes by pipe 39 to pump 40. From here it passes to heater 28 by pipe 41, condenses steam therein, and passes by pipe to the next pump, and so on through the various heaters. The pumps 40, 43, 46 are on one shaft. Tanks 49, 61 and control apparatus are associated with heaters 30, 32. The connections between the pumps and heaters are arranged to provide sufficient head to effect an automatic adjustment between the various pump elements so that one regulator controls the combined units. The levels in the tanks 49, 61 depend upon the amount of steam used in the turbine. Float chambers are associated with the tanks. The floats affect pilot controllers. 68, 71 having electric contacts which control reversible, constantspeed motors 75, 77 to operate rheostats 76, 78 to vary the speed of the pump motors 69, 48. A float regulator may be placed in the hot-well 38. The pump units may be arranged on a single shaft and driven by a single motor. A float in a chamber 55 may be arranged beneath the heater to control a valve 74 in the discharge pipe. Valves opened or closed by oil pressure against the resistance of springs are arranged in the bleed-steam lines, and are closed when the emergency gear operates. Check valves 90 prevent accidental back-now of water through the bleed mains.

Title: Under-colour removal in colour reproduction systems
IPC: H04N1/60
Filed: 1957-09-06
Abstract: 812,322. Copying in colour by scanning. TIME Inc. Sept. 6, 1957 [Sept. 26, 1956], No. 28158/57. Drawings to Specification. Class 40 (3). Relates to a facsimile colour reproduction system for the production of three colour printers together with a black printer and in which " partial undercolour removal is employed as described in Specification 761,535 whereby in each area of a reproduction only part of the black is carried by the black printer, the remainder being provided by the three colour printers. In contrast to Specification 761,535 where the percentage undercolour removal remains constant, the present invention provides for a variation in the percentage removal, 71 per cent being employed in the shadows and 50 per cent in the highlights. In terms of the relationships for the glow lamp currents given in expressions 10 and 12 of Specification 761,535, the invention involves varying the exponent n of the selected maximum colour signal, i.e. the black signal. The undercolour removal is effected by modulating the colour signals by the black signal in non-linear modulator stages, and to carry out the invention the black signal is first passed through an amplitude selective distortion circuit, the characteristic of which together with the modulation characteristic of the modulators are arranged to render the amplitudes of the colour signals a function of the black signal raised to an exponent which varies as a function of the black signal from 0.71 for shadows to 0.5 for hiahlights. The modulators have the general characteristic where E 1 , E 2 , E 3 , K and p are respectively: the input colour signal voltage, the black signal voltage, the output voltage a constant and an exponent less'than one. If p is made equal to 0.5, the amplitude selective distortion circuit for the black signal is chosen as an exponential expander which provides expansion only over the lower end of the signal range corresponding to shadows, the output becoming thereafter a linear function of input. By this means, the value of p is effectively raised to 0.71 for shadows. Alternatively, if p is made equal to 0.71, the distortion circuit is chosen as an exponential compressor which compresses the signal only over the highlight range so that p over this range is effectively reduced to 0.5. U.S.A. Specification 2,580,692 also is referred to.

Title: Ethylene interpolymers
IPC: C08F10/00
Filed: 1959-08-18
Abstract: Normally solid copolymers of ethylene with an o -hydroxyalkyl vinyl ether, in which the alkyl group has 2 to 6 carbon atoms, are made, for example under the high pressure conditions used in the free-radical catalysed polymerization of ethylene.  The vinyl ether may be g -hydroxypropyl or d -hydroxybutyl vinyl ether and is preferably b -hydroxyethyl vinyl ether.  The preferred copolymers contain a molar proportion of ethylene in excess of that of the vinyl ether.  The use of a catalyst is preferred, e.g. oxygen or peroxide catalysts of which a list is given including acyl and diacyl peroxides, ketone peroxides, hydroperoxides, zinc peroxide, peracetic acid and salts of inorganic per-acids or an azo catalyst, e.g. bis-benzene diazosuccinate, salts of 2,21-diguanyl-2,21-azopropane, 2,21-azobis(methylisobutyrate) and 2,21-azobis (isobutyramide).  The polymers may be cross-linked through the bydroxyl-groups, e.g. by curing with organic polyisocyanates or polyisothiocyanates and a list of suitable polyisocyanates is given.  The reaction with isocyanates may be carried out in an inert solvent, e.g. toluene and xylene and in the presence of tertiary amine catalysts and also small amounts of water to produce foamed articles.  The copolymers may be compounded with stabilizers such as stannous stearate, lead stearate, dibutyl tin dilaurate, epoxy resins, glycidyl ethers of alkylene glycols, sulphides of dialkyl phenols and di-b -naphthyl-p-phenylenediamine, and with polyester p  plasticizers, cellulose, starch, carbon black and silicate and clay fillers.  They may be moulded and cast, and used for coating wires and metal sheets and for laminating metal, e.g. aluminium, sheets.
