Title: Improvements in or relating to process and apparatus for the manufacture of a stiffened or reinforced web,advantageously of paper
IPC: B31F5/00
Filed: 1963-10-10
Abstract: 1,025,516. Laminates and laminating. W. ROSLER, and J. ROSLER, [trading as DRAHTWERKE ROSLER KOMM-GES.]. Oct. 10, 1963 [Oct. 18, 1962], No. 40088/63. Heading B5N. Reinforced sheet material, e.g. textile, plastics foil or, preferably, paper, comprises two webs of the material bonded together with an interlayer of longitudinally extending filaments or wires and transversely extending filaments or wires, the latter being formed from a continuous filament or wire laid sinuously. In the continuous production of such sheet material, webs 3, 4 (Fig. 2, not shown) are fed via adhesive applicators where they receive a coating, e.g. of bitumen, on the surfaces to be united, to the nip of cylinders 6, 7, longitudinal filaments 10 also being fed to the nip, at a predetermined spacing, from spools 8 (not shown). To form the transverse filaments, a filament 12 is fed to a guide member 15 which is caused to reciprocate in an arcuate slide track 16, by a beater device comprising an upper beater 22 (Fig. 4, not shown), and a lower beater 23 which is coupled therewith and which is driven by a crank 25 from a shaft 24. From the guide member the filament is laid around a finger 21 of a width-retaining member 19 on one side of the cylinders 6, 7, and the guide member moves to the other side of the cylinders. In this position the filament forms a chord to the arcuate track 16 and is transported with the webs through the nip. Simultaneously, the finger of the width retaining member on the same side as the guide member pivots about a pin 20 and engages the transverse filament, whilst the width retaining member on the other side pivots out of engagement of the loop which has been formed. The guide-member then moves to the other side of the slide-track and the cycle repeats itself. Optionally, instead of using bitumen, one or both webs may have a watersoluble adhesive coating, in which case the applicators apply water to webs to activate the adhesive.

Title: Improvements in or relating to apparatus for studying rheological behaviour of plastic lubricants
IPC: G01N11/10
Filed: 1961-11-13
Abstract: 1,000,152. Studying plastic lubricants. HOUILLERES DE BASSIN D'AQUITAINE, and G. CUEYE. Nov. 13,1961 [Nov.16, 1960], No. 40556/61. Drawings to Specification. Heading G1N. In an arrangement for studying the behaviour of plastic lubricants one element of a bearing lubricated by calibrated measures of the lubricant under test is driven at a predetermined speed or series of speeds by a D.C. motor the armature current of which is measured by measuring the potential across a shunt as an indication of the drag torque of the bearing. The bearing is housed in a chamber the temperature of which is controlled by air conditioning plant to be held constant at any temperature between -20‹C.to 180‹C. or to follow a programme, and the torques, lubricant temperature and test chamber temperatures are continually sequentially recorded on the same recording tape through a selector switch, the drive of which is synchronised with the tape. The motor is coupled to the bearing via a clutch and drives also a tachometer generator, its speed is regulated by adjustment of the D.C. bias on a thyratron through which the armature current is supplied, the tachometer output being also applied to the thyratron to hold the speed constant. Ward Leonard or variable inductor control may be used. In a servomotor arrangement for controlling the temperature and for providing an indication thereof described with reference to Fig. 14 (not shown), cam operated contacts control the supply of hot or cold air obtained by passing the fan output over heater or a refrigerator. For the programming of temperature, the thermocouple voltage is opposed by a reference voltage corresponding to the desired temperature obtained from a slide wire by a mechanical cam arrangement. The manner of calibration is described and changes of torque with speed and temperature are described with reference to Figs. 19a-19d.

Title: Digesters
IPC: D21C7/00
Filed: 1960-11-25
Abstract: 939,604. Endless conveyers. BAUER BROS. CO. Nov. 25, 1960 [Nov. 30, 1959], No. 40695/60. Class 78 (1). [Also in Group XIII]  A continuous treatment digester of the moving conveyer type consists of a cylindrical tube closed at both ends, one end having a closure unit with an inwardly facing concave surface, a conveying means in the tube to conduct fragmentary fibrous material continuously along the tube from an inlet to the concave surface and then back along the tube to an outlet, and flights on the conveying means to receive the fragmentary material in loosely packed form, each flight having a leading inclined edge that leads the flight into the turn at the end with the closure unit. The digester as shown has an inlet 29 and an outlet 36 in the tube shell 10 and is filled with a quantity of cooking liquor below the levels of the inlet and outlet. A rotary valve 33 admits predetermined metered quantities of fibrous material, which is conducted down the tube by the continuous conveyer which consists of a chain or chains 19 with flights 26. The material is turned through 180 degrees in an arcuate passage 35 formed by the concave surface 16, and conducted up the tube to the outlet 36 and a rotary outlet valve 38. The tube 10 is partitioned off into upper and lower flight passages 24 and 25 respectively, by a hollow central partition 23. It is around the end of this partition 23 that the leading inclined edges of the flights 26 turn, so keeping the volume between two flights approximately equal in the flight passages 24, 25 and the arcuate passage 35. The closure unit 14 constitutes a false bottom to the tube 10, and consists of a cylindrical portion 15 slidably mounted in the tube 10 and a hemispherical part forming the concave surface 16. The cylindrical part 15 extends beyond the hemispherical part and provides rotary bearings for a transverse shaft 17 on which are mounted discs 18 providing guides and mountings for the chains 19. The chains are driven by sprockets 21 mounted on a transverse shaft 22 driven by an external means not shown. A compression spring 44 is based on a plate 45 forming part of a stuffing box 43 on the bottom of the closure cap 13, through which passes a rod 42 attached to the closure unit 14. The spring reacts against a stop 46 adjustably mounted with a nut 47 on the end of the rod 42, and keeps the chains 19 under tension. Specification 939,271 is referred to.

Title: Safety Control System particularly for a Nuclear Reactor
IPC: G21C7/36
Filed: 1968-08-28
Abstract: 1,197,528. Controlling reactors. COMBUSTION ENG. Inc. 28 Aug., 1968 [15 Sept., 1967], No. 41184/68. Heading G1C. In a nuclear reactor safety control system, the control rods are released so as to shut down the reactor, when variables monitored, such as primary coolant flow, water level, load and neutron flux, vary from predetermined values. Each variable is monitored by several, independent, sensing devices which are arranged in groups, each group containing one sensing device for each of the variables. Each sensing device energizes an associated relay coil during normal reactor operation and the coil is deenergized to fail safe when the undesirable condition of the variable monitored occurs. The contacts controlled by the relay coils are arranged in a number of independent matrices, each of which incorporates the contacts of some of the relays. This results in " redundant instrumentation " which permits correct operation of the safety control system when only some of the sensing devices are functioning satisfactorily. In a further embodiment, the control circuit is formed of a number of isolated sections, each supplied from a separate energy source.

Abstract: 895,076. Nuclear fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 4, 1959 [Dec. 5, 1958], No. 41289/59. Class 39 (4). A nuclear fuel element casing comprises a cylindrical body 13 provided with sets of fins 14, 15, having the shape of portions of helices, each set being of opposite hand to that of adjacent sets. Narrow passages C 1 , C 2  may be provided between the sets of fins, or the fins in one set may be joined to those of adjacent sets to form a herring bone shape right round the casing. The fins in one set may be staggered with relation to the fins in an adjacent set and the two sets of fins may overlap, forming a broken passage between the sets. The space between the fins may vary throughout one set or from one set to another. The passage between the sets of fins may be longitudinal with respect to the casing or shaped as a helix of distinctly greater pitch than that of the fins. Fins may also be of differing height or inclined at an angle to the body of the casing. The construction of the fins creates turbulence in the cooling fluid and so improves heat exchange.

Title: A cash register
IPC: G06C11/02
Filed: 1965-10-04
Abstract: 1,118,216. Cash registers. STYNER & BIENZ A.G. 4 Oct., 1965 [17 Feb., 1965], No. 41926/65. Heading G4T. A cash register comprises differential racks 62 adapted for movement to positions determined by stops of a keyboard and at least one indicating device 68 and one calculating device 95 operable by the racks, the racks being continuously directly coupled via gearing with numeral wheels of the indicating device. The wheels of the calculating device, on the other hand, may be brought into or out of engagement with racks 97 displaceably mounted on the racks 62. In each denomination, when a key is depressed, its inclined surface engages a corresponding surface of a control bar 34, whereby the control bar is shifted into its lower position. The depressed key is locked in position by a tooth on the control bar 34 whereas the other teeth of the control bar engage below teeth of the keys remaining in their undepressed condition. When shifted, each control bar engages with its surface 52 below the web 53 of the associated zero stop 53, 54 and lifts the stop into the inoperative condition shown. The start key 25 is then depressed and main cam-shaft 10 executes one full rotation and the gear 11 through gear 9 completes two revolutions. At the beginning of the rotation of gear 11, the cam 147 lifts lever 150 so that slide (152) is moved to the left so that lugs (153) are spaced from arms (106) of stop latches (101) (Fig. 9, not shown) associated with racks 97. At the same time, a recoil stop 70, 71 (Fig. 4) is completely disengaged by rotation of the cam disc 74 so that all differential racks 62 are free to move. Shortly after the beginning of the cycle, cam disc 344 allows lever 44 and release bar 42 to swing, whereby all control bars 34 which have not been displaced by a key are now pulled downwards into a keyboard locking position by their hooks 40 engaging into slots 41 of the release bar. The operating cycle comprises two phases. During the first phase, the racks 62, which have been set during the previous cycle, are restored and the amount registered thereby entered into the calculating device 95 by racks 97, tens transfer being effected by means of the latches (101). During the second phase, the racks 62 are re-set in accordance with the keys now depressed, the racks being differentially stopped by tongues 33 on key-carried lugs 32 engaging pressed-out projections 69. The numeral wheels 68 have resilient spokes.
