Title: Improvements in or relating to composite pigments
IPC: C09C1/00
Filed: 1962-04-02
Abstract: A process for preparing a titanium dioxidecalcium sulphate composite pigment comprises forming an anhydrite aqueous slurry in which the particle size of the anhydrite is from 0,30,7 microns, admixing titanium sulphate with the slurry and heating the mixture to boiling to hydrolyse the titanium values to form a co-precipitated hydrate, adding to said hydrate a titanium sol. as defined below and zinc as metallic zinc, zinc oxide, zinc titanate or a compound of zinc which upon calcination in the presence of titanium hydrate produces zinc titanate or zinc oxide, the amount of sol. being at least 0,3% and the amount of zinc calculated as zinc oxide being at least 0,5% both of which amounts are based on the weight of the titanium dioxide in the hydrate, and calcining the treated hydrate at a temperature between 840 DEG C. and 950 DEG C. sufficient to convert at least 90% of the titanium of the treated hydrate to the rutile crystal structure to form a titanium dioxidecalcium sulphate composite pigment, the amount of heating being insufficient to develop undertones that degrade the colour tone when the pigment is used in tinted or white paints.  The titanium sol. added is a semi-colloidal titanium material consisting of acicular crystals ranging in particle size from 50-1500  and having a crystal structure of at least 15% rutile. The zinc compound added may be zinc hydroxide, zinc sulphate, a zinc halide or an organo-zinc compound.  Examples are given of the use of different titanium sols. and these are compared with the results when no titanium sol. or when no zinc is added. Specification 848,617 is referred to.

Filed: 1960-04-11
Abstract: 896,069. Extruding. SCHLOEMANN A.G. April 11, 1960 [April 23, 1959], No. 12769/60. Class 83 (4). An extrusion press has a press disc 5, Fig. 2, cooled by air or gas. The disc is in two parts 14, 15 secured to the end of the press ram 4 mounted on a cross-head 6 driven forwardly by a main piston 8, Fig. 1, and retracted by plungers 11. In the extrusion of aluminium billets 3 at 500‹ C., selective gas or water cooling may be used under the control of three-way valves 29, 40 coupled together at 70 and actuated manually by remote control, or automatically in dependence upon the disc temperature or the position of the press ram. Inlet valve 29 is connected through pipe 28, containing a flow meter 68, flexible hose 27 and pipe 26 with the ram bore 16 which leads to an annular cooling chamber 19 in the disc. The coolant is exhausted therefrom through pipes 24, 37, hose 38 and pipe 39 leading to the exhaust valve 40. For gas cooling, valve 29 is moved into position 29a whereupon air or preferably nitrogen, charged into receiver 34 by compressor 35 passes into the disc and is exhausted therefrom through valve 40, then in position 40a, into the atmosphere. For water cooling, water is supplied through valve 29 by a pump 31 driven by motor 32 and is exhausted through valve 40 to three-way valve 50 controlled by thermostat 51. If the motor temperature is below 70‹ C. it passes directly into tank 43 which feeds pump 31; if the temperature is above 70‹ C. it passes into the tank through a cooler 53 which is circulated with coolant through filter 59 by a pump 56 driven by motor 57. The tank 43 has a filler pipe 44, overflow 46, sight glass 47 and electric heater 48. Telescopic pipes may be used instead of the hoses 27, 38.

IPC: G06C7/10
Filed: 1925-05-16
Abstract: 235,539. Krupp Akt.-Ges., F. June 16, 1924, [Convention date]. Cash registers with several itemvalue totalizers; differential mechanism.-Two differential members each controllable by its own bank of keys are connected in such a way that one member may also be controlled by the other. In the machine shown, the clerks bank of keys I - - V and the transaction bank A, C, R are disposed in echelon as seen from the front and the interconnection of their differential mechanism is such that the selection of the totalizer for actuation is effected by the differential mechanism of the transaction bank under the control of a key in either bank. Thus if a clerk's key only is depressed the differential mechanism of the transaction bank is positioned by that key, but if a key in each bank is set this differential mechanism is controlled by the transaction key. The differential mechanism is of the known latch type and the totalizers h<1> are arranged for radial displacement towards and from the actuating wheels f<2>, controlled by the amount keys B, and disposed within a drum-like casing G<1>. The cam disc J carrying the radially-slidable block J' grooved to effect the displacements of the selected totalizer is positioned by the differential member C<1> of the transaction bank, the latch c<3> of which (Fig. 11) is adapted to engage a transaction key. If no such key is depressed a pin c<23> on this latch will engage a similar pin c<17> belonging to the latch of the clerk's differential mechanism thus effecting the selection of the corresponding clerk's totalizer. The movement of the selected totalizer into and out of gear is produced by a grooved cam K connected by a sleeve k<3> with a pinion k<1> gearing with a toothed portion of the driving disc c<10> of the transaction differential mechanism.

Title: Telephone set
IPC: H04M1/23
Filed: 1965-03-26
Abstract: 1,094,335. Telephone sets. STANDARD TELEPHONES & CABLES Ltd. March 26, 1965 [April 1, 1964], No. 12911/6.5. Heading H4J. A telephone substation provided with a loudspeaking unit (not shown), and a handset 1 has a push-button for connecting to a trunk, secretarial or calling line and a second pushbutton 3 which, when pressed with the handset in its cradle rest, connects the loud-speaking unit to the substation line. When the substation is not in use (i.e. as shown in Fig. 1) the weight of the handset 1 in its cradle rest causes a cradle lever 5 to urge a spring-urged slide 7, via engagement of a pin 6 and a claw 7<SP>1</SP>, against the action of the spring to hold the left-hand push-button (a " trunk " push-button) locked. The substation can be brought into use by first removing the handset 1 from the cradle rest (Fig. 2, not shown). This operates a switch (not shown) to connect the handset 1 to the substation line. The spring then moves the slide 7 to unlock the left-hand (" trunk ") push-button for operation. Alternatively, the substation can be brought into use by first pressing the " loud-speaking " push-button 3. The slide 7 is thereby disconnected from the cradle lever 5 and, even though the handset is still on the cradle rest, the spring moves the slide 7 to unlock the left-hand ("trunk") pushbutton for operation. Once the " loud-speaking" push-button 3 has been depressed it is possible to change to use of the handset 1 by removing it from the cradle rest, and to change back to the use of the loud-speaker unit by replacing the handset 1 in the cradle rest. A call-completed push-button (not shown) when depressed releases the " loud-speaking " push-button and effects re-engagement between the claw 7<SP>1</SP> and the pin 6. Further pushbuttons may be provided for calling or secretarial connections.

Title: Improvements in or relating to apparatus for cleansing and drying hollow articles especially milk and the like cans
IPC: B08B9/08
Filed: 1925-05-19
Abstract: 256,348. O'Connell, J., and Kerr, H. H. May 19, 1925. Milk cans and the like, cleaning.-A device for cleaning hollow articles, particularly milk cans, comprises a tank 1 supporting a shell 17 provided with an angular opening and enclosing a rotatably-mounted grid formed of members 20, 21, the grid together with partitions 19 forming compartments each of which is adapted to receive an inverted milk can and a lid. The partitions 19 and the members 20 are secured to a sleeve 11 surrounding a column 2. The lid is held in place by a spring-pressed arm 24. The grid is provided with a rack 27 engaging a pinion 28 mounted on a shaft 29 which carries a toothed wheel 34 gearing with a pinion 35 on a shaft carrying fast and loose belt-driving pulleys 38, 39. The shaft 29 is provided with a wheel 74 formed with a notch 73 which is adapted to be engaged by a dog 72 on a spring-pressed lever 68 provided with a belt-shifting fork 76. When the dog 72 engages with the notch 73 the fork shifts the belt 40 on to the loose pulley 39, and the rotary movement of the grid stops. To start the grid, the handle 67 of the lever 68 is actuated to shift the fork and disengage the dog 72. In the construction shown, there are five compartments within the shell 17 occupying stations A - - E, and the arrangement is such that a milk can in a compartment passes from one station to the next, being stopped automatically on reaching a station and being re-started at the will of the operator, and during the intervals of rest it is subjected to the action of steam, sprays of cleansing liquid, hot water, and hot air. At station A where the milk cans are deposited on the grid and removed therefrom, there is provided a nozzle 58 in communication by a pipe 55 with a steam manifold 56. The supply of steam is controlled by a valve 51 operated by means of a cam 42 on the shaft 29. At station B, the cream, &c. from the can is collected by means of an arm 111, partly immersed in cleansing solution in the tank 1, the arm diverting the scum on the solution to an opening 112. The solution is kept rotating by admission of steam through a nozzle 90 connected by a bridge piece 92 to a pipe 91. The can at station C is subjected to sprays of cleansing solution pumped through nozzles 88, 89 for cleansing, respectively, the interior and exterior of the can. At station D, the can is cleansed by hot water from nozzles 66, 66a, the hot water being formed by condensation of steam in pipes 94<a> submerged in the cleansing solution. The water is forced out by pressure of steam controlled by a valve 59 which is actuated by a cam 43 on the shaft 29. By means of a dash-pot 63 the closing of the valve 59 is retarded sufficiently to allow all the condensed water to be removed from the pipes 94a. At station E, the can is dried by means of a fan which forces air into a chamber beneath the tank 1 and up through pipes 109. The air is heated as it passes below the tank.

Abstract: 583,956. Brake shoes. PRATT, J. H., and IRVING, J. S. July 8, 1944, Nos. 13095 and 16625. [Class 103 (i)] In brakes of the kind described in Specification 519,787 in which the shoes are not positively held out of contact with the drum but are in light rubbing contact therewith when the brake is in the "off" position, the backing afforded to the lining by the arcuate surface of the shoe is relieved at one point to allow the lining at that point to yield inwardly when the brake is applied and so wear at a lower rate than the remainder of the lining. When the brake is in the "off" position, the less worn part of the lining stands slightly proud and prevents contact of the remainder of the lining with the drum. The relief may be provided either by reducing the resistance to local bending of the shoe at one point or forming a flat or groove in the surface of the shoe flange. The point of relief may be located at or near the point of least drag between the shoe and drum. In one form, Fig. 1, a triangular opening d is formed in the web a of the shoe adjacent the flange b, and, if desired, a saw-cut e is made in the flange b. Alternatively, Fig. 3, a flat or groove f is formed in the surface of the flange b, or a portion of the surface of the flange is curved to a radius greater than that of the remainder.
