Filed: 1976-12-06
Abstract: 1508623 Postage meters VICKERS Ltd 6 Dec 1976 [5 Sept 1975] 36756/75 Heading B6C Circuitry for a postage meter includes a digital electronic input register, a digital electronic total register, setting means for setting a printing device to the value in the input register, and totalling means for adding the value in the input register to that in the total register and placing the new total in the total register. Input may be manual, from a remote source, or from a weighing machine. Registers may also be provided for first and second class franking numbers, the number of labels as distinct from envelopes printed, the total number of frankings, and a credit register stepped down by each franking effective to prevent operation when no credit is left. The credit register may be protected by seals, combination locks and/or code keyings from access other than by authorized personnel. Alterna. tively, credit may be added using a single-use credit card with coded credit data which the machine reads and then charges the card to prevent reuse. The circuitry and keyboard may be in a removable module mounted on the printing device, the circuitry module being removed to a post office for replenishment of the credit register. The registers are preferably prevented from loss when power is disconnected by use of non-volatile memories, or volatile memories protected by battery power. The circuitry disclosed incorporates a number of fault-sensing procedures, e.g. if the setting of the printing machine takes more than a predetermined time, a printer fault is indicated and the machine locked; if the total register overflows or is about to overflow, or if the credit proposed to be added to the credit register is such as to produce an overflow, this is indicated; condition of the backup batteries may be tested; if a franking operation of more than a set value is required, this may only be achieved by a further keying operation; and this may be indicated by intermittently flashing the display. The circuitry may also enable any of the values in the registers to be displayed, and the display may include a fault-indicating position displaying codes representing the fault.

Title: Alkaline earth metal silicates and method for their treatment
IPC: C01B33/24
Filed: 1956-12-05
Abstract: A finely-divided amorphous alkaline earth metal silicate e.g calcium silicate having a surface area of 20-70 sq.m/g. may be obtained in the form of non-dusting water dispersable pellets, having a bulk density of at least 16 lbs./cu.ft. suitable for use in pigmenting paper, by tumbling in a container e.g. a rotatable cylindrical drum, at least half full, preferably 50-75% full, of said silicate. Tumbling may alternatively be obtained by a rocking or gentle shaking motion.  The bulk density of the initial material is normally from 9-14 lbs./cu.ft., and it may be prepared by reacting sodium silicate and 5-30% in excess of the stoichiometric amount of an alkaline earth metal chloride with gentle agitation under such conditions that the solutions are distributed throughout the reaction medium: in an example calcium silicate was prepared by admitting a plurality of streams of sodium silicate solution on to the surface of the reaction mixture in a tank into which the calcium silicate was introduced from below.  Air was passed into the tank to provide the desired agitation.  The so-formed slurry was removed, washed, filtered and dried to produce a calcium silicate of surface area 32-36 sq.m/g. and having a formula CaO.(SiO2)x where x = 3.1-4.75 depending on reaction conditions.  This material was charged into a rotary drum containing baffles parallel to the axis to facilitate tumbling, and rotated. Pellets were formed and increased in bulk density as the rotation was continued until a final bulk density of 23.4 lbs./cu.ft was attained: in another example a bulk density of 26.3 lbs./cu.ft. was obtained.

Abstract: 879,222. Supplying fuel to burners. LUCAS (INDUSTRIES) Ltd., JOSEPH. Dec. 9, 1957 [Dec. 10, 1956], No. 37610/56. Class 75(1). [Also in Group XXVI] A liquid fuel system .for a spill burner comprises a pair of proportional flow valves a, a<SP>1</SP> connected respectively to the supply pipe d and the spill pipe r, an intermediate passage s connecting the valves, a throttle u in the spill pipe, a secondary spill passage t communicating with the valve a<SP>1</SP> in the spill pipe and means dependent on the pressure difference across an aperture 4 in the secondary spill passage t for actuating the throttle u. The flow valve a includes a main passage e having a restricted orifice f and a chamber which divided into two compartment g, i by a flexible diaphragm k. The compartment g is connected to the main passage e by a passage o having a restricted orifice p. The compartment i is connected to the main passage e by a passage q. The diaphragm k carries a closure member n for a seating m. The return valve a<SP>1</SP> is similar to the flow valve a. The intermediate passage s extends from the seating m of the flow valve a to the compartment g<SP>1</SP> of the return valve a<SP>1</SP>. The throttle u is attached to a diaphragm y dividing a chamber into two compartments w, x. A tension spring z acts on the diaphragm y to close the throttle. The secondary spill passage t is connected to the compartment x and the compartment x communicates with the compartment y through the aperture 4 controlled by a plug 5. When the pump b is started the fuel pressure lifts both closure members n, n', and the fuel pressure in the secondary passage t opens the throttle u so that a large proportion of the fuel is returned from the burner c. If the plug 5 is retracted from the aperture 4 the fuel pressure difference acting on the diaphragm y is reduced so that the throttle moves to its closed position to reduce the amount of fuel returning from the burner c. The plug 5 may be actuated manually or by means responsive to a variable factor e.g. engine speed, temperature, pressure. In a modified construction the aperture 4 is constant and the tension of the spring z is varied by a pinion and rack to operate the throttle u.
