Title: Improvements in and relating to power rebate meters, more especially of the prepayment type
IPC: G07F15/08
Filed: 1935-04-08
Abstract: 435,692. Electricity meters ; prepayment mechanism. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. April 8, 1935, No. 10858. Convention date, April 2. [Class 27] [See also Group XXXVI] A power rebate electricity meter, particularly for use with prepayment mechanism, comprises an ordinary Kilowatt-hour or amperehour meter 1, Fig. 1, driving one sun-wheel 32 of a differential mechanism 3, and a second meter 2 driving in the same or in the opposite direction the other sun-wheel 31, the meter 2 having a brake mechanism 22 so that it commences to run only when the rate of consumption exceeds a predetermined limit. The voltage coils 10, 20 of the meters are connected in parallel and the current coils 11, 21 in series. The planet wheel of the mechanism 3 drives a shaft 33 which returns to zero the usual differential mechanism of a prepayment mechanism 34. When the sunwheel 31 is driven in the opposite direction to the drive of the sun-wheel 32, the shaft 33 is rotated more slowly than if the meter 1 alone were in action and electricity is supplied at a cheaper rate above the predetermined rate of output. If a higher price is to be charged when the output is above the limit, the sun-wheel 31 must be driven in the same direction as wheel 32. A registering mechanism 12 driven by the meter 1 indicates the total consumption. The brake mechanism 22 may be arranged to act during a small fraction of a revolution of the rotor 2, so that the meter runs at a speed corresponding to the total power In a modification, Fig. 5, instead of the differential 3, a ratchet gear may be used, one pawl 36 being driven by the meter 2, and the other pawl 37 by the meter 1. If the price is decreased upon an increase of output, a locking device is provided for putting the meter 1 and pawl 37 out of action. If the price is increased with an increase of output, the pawl 36 overruns the pawl 36 and a locking-device is unnecessary.

IPC: D21F5/14
Filed: 1922-04-19
Abstract: 202,672. Minton, O. April 19, 1922. Drying.-In apparatus in which a web 1 is fed to and from a vacuum drying chamber through barometric seals, in order to reduce the volume of the seal and to prevent flapping of the web, the sealing chamber is cylindrical and nearly filled by a guide cylinder, and the web enters the seal in a substantially vertical plane, passes horizontally to the guide cylinder, and leaves the seal in a vertical plane. The vacuum chamber 34 comprises two sealing chambers 45, 46, nearly filled by the guide rollers 38, 44. The web is fed through the seals between endless bands of felt 36, 37, which are as wide as or wider than the web, so that the web is exposed only at its edges in passing through the seals. The upper band leads the web over the upper drying cylinders 39, 41, 43 and the lower band leads it over the lower cylinders 40, 42. The guide cylinders 38, 44. in the sealing- chambers may be steam-heated, forming additional drying cylinders. Steam jets may be arranged at 35, directed so as to strip the web from the cylinders and from the felts for threading the machine initially or when the web breaks. In other forms of the apparatus, the web meets and leaves the guide cylinders horizontally, both guide cylinders are arranged in a single sealing chamber, and the felts may be dispensed with. Specifications 142,810, 176,614, [Class 34 (i), Drying gases &c.], and 200,600 are referred to.

Title: Improvements in the heat process of manufacturing ferric oxide
IPC: C01G49/06
Filed: 1924-05-05
Abstract: In the manufacture of ferric oxide especially for use as a pigment, ferrous sulphate is first dehydrated, then ground to a fineness sufficient to allow it to pass through a mesh of 150 or upwards, but preferably of 200 to the inch and then roasted in a rotating inclined furnace.  The evolved gases are drawn off by a fan to be treated in the usual way for the production of sulphuric acid.  The ferrous sulphate crystals are first crushed and then fed on to a travelling grate maintained at a temperature varying from 400 DEG  to 500 DEG C.  The dehydrated product is ground, the length of treatment being sufficient to convert the material into a yellow to white mass containing no green crystals, and air-separated to give a powder of uniform fineness such as will pass for example through a 200-mesh sieve and is roasted in a rotatable furnace fitted with baffles.  The furnace is heated to a temperature of 800 DEG  to 900 DEG  C. and a current of air preheated to about 700 DEG  C. is drawn through it by a fan.  The concentration of the evolved sulphur trioxide and dioxide should not exceed 8 per cent.

Title: Manufacture of acid dyestuffs of the anthraquinone series
IPC: C09B1/34
Filed: 1932-04-18
Abstract: Greenish-blue dyes of the anthraquinone series are obtained by treating a 1-amino-4-halogenanthraquinone-2-sulphonic acid or a salt thereof with an amide of an aminocarboxylic acid of the benzene series or a derivative thereof, in which the amide group may be substituted by alkyl, hydroxyalkyl or cyclohexyl groups. According to examples the sodium salt of 1-amino-4-bromoanthraquinone-2-sulphonic acid is condensed with o-, m-, or p-aminobenzamide, 3- and 4-chloro-1-amino-5-benzamide, o-, m-, or p-aminobenzoic cyclohexylamide, m-aminobenzoic dimethylamide, and corresponding 3- and 4-chlor derivatives thereof, p-aminobenzoic methylamide, o-, m-, or p-aminobenzoic ethanolamide; o-, m-, and p-aminobenzoic mono and diethyl amides and chloro substitution products of these are also specified. Specifications 10378/14 and 7861/15, [both in Class 2 (iii), Dyes &c.], are referred to.  The amino-carboxylic amides employed are obtained by causing a nitrocarboxylic chloride of the benzene series to condense with an amine or ammonia, followed by reduction of the nitro group.

Title: Improvements in brake operating mechanism
IPC: B60T11/16
Filed: 1943-07-09
Abstract: 570,186. Hydraulically - operated brakes. GIRLING, Ltd., and GREEN, A. H. July 9,1943, No. 11142. [Class 103 (i)] A brake-operating system comprises a mastercylinder 3, the pressure chamber 3a of which is connected by passages 3b, 3c and pipe-lines to one set of brakes, for instance, the front brakes of a vehicle, and a piston 6 normally operated by the pressure in chamber 3a and connected by mechanical linkage 10 to another set of brakes, for instance, the rear brakes of the vehicle, so that normally proportional pressure is applied to the two sets upon operation of the pedaloperated piston 4. The movement of the piston 6 is limited by a stop ring 11 so that in the event of failure of the rear brake mechanism, hydraulic pressure may still be developed in the chamber 3a to apply the front brakes. Also, if the hydraulic system should fail, an'extension 4a of the piston 4, slidable in the socket 6b extending from the piston 6, engages the latter piston when the piston 4 is operated and ensures the operation of the rear brakes. A reservoir is normally connected to the chamber 3a through passages 9a, 9b in the screw-plug 9, and passage 3b but is cut off during a brake application, by the ball-valve 15 which then seats at 13. Specification 478,328 is referred to.

Title: Gauging apparatus
IPC: G01B7/00
Filed: 1972-06-22
Abstract: 1364292 Gauging diameters and tool movement THOMAS MERCER Ltd 22 June 1972 [23 April 1971]  11152/71 Heading G1M [Also in Division B3] A gauging apparatus comprises a first probe 3 for measuring a dimension of a workpiece, a second probe 2 for measuring displacement of a tool reducing the dimension of the workpiece, and a gauging unit adapted to display values sensed by the probes. The apparatus may be used in a machine for turning or grinding cylindrical workpieces. As described the probe 2 senses the movement of a grinding wheel and probe 3 is mounted in a caliper 4 for measuring the diameter of the workpiece 5. A changeover switch 11 connects one or other of the probes to the unit which has a further switch 12 so that either English or Metric units are shown on a display 6. Each probe is associated with a zeroing control 9, 10 and a calibration control 7, 8. The apparatus is set by inserting a master in the caliper 4. The unit has a range of DÀ1" or 2mm, and the master is selected from a range according to the desired diameter of the workpiece. In use, the master is placed in the caliper which is adjusted so that the unit displays the size of the master. The grinding wheel then effects one or more initial units in the workpiece and, with the switch operative to connect probe 2 to the unit, the display is adjusted to indicate a convenient number, say 1000. When the caliper is engaged with the workpiece, the desired diameter is subtracted from that indicated by probe 3 when the switch 11 connects that probe to the unit. Thereafter, with switch 11 activated to connect probe 2 to the unit the workpiece is ground until the subtracted amount referred to above is added to the above convenient number i.e. 1000. In another embodiment, hand operated wheels 14, Fig.2, can be set to the desired dimension and, with a workpiece in the calipers, a 'store' button 15 is pressed and the difference between the actual size and the size set on the wheels is indicated on a display 13. During traverse grinding, a hold switch is operative so that only the size at one end of the traverse is indicated. The read-out may be by meter instead of digital and the unit may be in the form of an air gauge rather than electronic.

Filed: 1974-03-13
Abstract: 1459831 Sprinkler system L C KAH 13 March 1974 11198/74 Heading AID [Also in Divisions F2 and G3] A sprinkler system comprises valves 50 (see Division F2) for delivering irrigating water to different areas, the valves being selectively operated by the pressure of water supplied to a signal pipe 14 by a pressure selector 10. The valves 50 are connected by conduits 6 to a main water supply 2, 2A and by conduits 8 to sprinkler units 4. The pressure A in the signal tube 14 is monitored by a pressure sensing transducer in the signal control means 10 and compared with the selected pressure B by means of an electrical signal. If A is larger than B, line 14 is automatically connected via a valve to dump line 30 to reduce the pressure and if A is less than B, line 14 is automatically linked to the pressure source 12 until the desired pressure is achieved. An automatic electronic signal producing device may be provided to produce electrical signals in a given sequence so that the corresponding areas are irrigated in that sequence. Each valve 50 comprises a spring biased diaphragm which can only be passed by the main flow of water when the pressure signal activates a valve which allows the pressure on one side of the diaphragm to alter to that pressure to which the particular valve 50 is adjusted.

Abstract: 768,911. Fluid-blast switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 19, 1955 [April 26, 1954], No. 11280/55. Class 38(5) Four arc extinguishing units 61, 47 are provided for a four-break, fluid-blast (as shown oil) circuitbreaker of the type described in Specification 759,461 and each comprises insulating plates cemented together, and vents 60 some at least of which are provided with spring metal valve members 75 to hold and control the pressure within arcing path 77. Unit 47 comprises a vent plate 68 having restricting portions 70 (Fig. 11) and a plate 76 (Fig. 17) providing inlets 90 and having integral flexible valve strips 80 to prevent a reverse flow of gas on high current interruption which could cause oil piston 49 to reverse. A further vent plate 84 has restricting portions similar to those 70 of Fig. 11. The other plates constituting unit 47 are similar to the ones already described but arranged as a mirror image. Unit 61 is similar to unit 47 but open inlet plates 91 (Fig. 14) replace the valve-controlled inlet plates 76, and each valve of this unit may, as shown in Fig. 2, comprise two valve members 75 thus causing unequal pressure conditions which causes additional oil flow towards unit 47, which is'stated to be a particularly suitable arrangement for intermediate values of currents. A modified type of unit (Figs. 4 and 5, not shown) with weak valve members but otherwise similar to unit 61 may be used in conjunction with similar units having no valve members (Figs. 1 and 9, not shown), The Specification describes also a form using outlet valve members of the type shown in Fig. 17 in combination with inlet valve plates 76 (Figs. 15 and 16, not shown). A cross-blast action can be achieved by providing valve members 75 on one side of the unit only (Fig. 20, not shown).
