Title: Calculating measuring apparatus,and more particularly a fluid dispenser
IPC: G06F7/62
Filed: 1962-07-27
Abstract: 1,016,766. Electric selective signalling; counting; counters. SOC. POUR TOUS APPAREILLAGES MECANIQUES S.A., and SUD-AVIATION SOC. NATIONALE DE CONSTRUCTIONS. July 27, 1962 [Aug. 4, 1961], No. 28996/62. Headings G4A. G4D and G4H. In a measuring apparatus, e.g. a fluid dispenser, a mechanically-driven pulse generator is used to drive counters which indicate the quantity measured and a proportional quantity, e.g. the total cost of the fluid dispensed. The pulse generator comprises a drum 6 (shown developed) having rows of holes 19 which co-operate with lamps and photo-cells to give thirteen pulse trains on lines 12. The drum is driven by way of a flow-meter 1 and rotates once for each 10 centi-litres dispensed. On line 12v there appears a pulse for each centilitre flow, there being 10 holes in row 19v. The pulses are counted on decade counters 13-17, and the count, indicating the total volume dispensed, is shown at 36. For each revolution of the drum 6 there appear on lines 12 1  to 12 9  one to nine pulses. The price of the fluid per 10 centi-litres is set on switches 20-23, this pre-setting selecting certain of lines 12 1  to 12 9  for feeding pulses to decade counters 28-32. In the present example, for each 10 centilitres counter 31 receives seven pulses, counter 30 receives three, counter 29 four, and counter 28 nine. The total cost of the fluid dispensed is shown at 38. Since one counter may receive a pulse while the counter of the lower decade is changing from nine to zero and thereby emitting a carry pulse, units 33-35 are provided. When set by a carry pulse a subsequent pulse on lines 12k-12m causes the corresponding counter 31-29 to be advanced by one. The cost is correct after each revolution of the drum. In a modification, Fig. 2 (not shown), 5 centilitres is the minimum volume that can be priced correctly. In this instance an arrangement of switches halves the price set at 37 so that the cost shown at 38 is correct for each 5 centi-litres dispensed.

Abstract: 1361514 Regulating fluid-flow GENERAL ELECTRIC CO 21 June 1972 [2 July 1971] 29088/72 Heading G3H [ Also in Division F2] A fluid-flow control device 20, suitable for use in a solenoid-operated valve 10 for maintaining substantially constant the volumetric flow-rate therethrough, comprises a resilient disc 15 which offers a first set of flow-paths 19a in the form of through-bores 21 and a second set of flow-paths 19b in the form of peripheral recesses 22. Face 27b of the disc, which face lies opposite to a seat shoulder 14, is formed with three by-pass pads 23, 24, 25 which project from a raised annulus 28, the annulus 28 being dimensioned and disposed to form a seal with the seat 14 when the two are brought into contact. The pads are of uniform thickness but of varying cross-sectional area, pad 23 being the smallest and pad 24 the largest. The provision of such pads results in a progressive engagement of the annulus with the seat so as progressively to cut off flow through the recesses 22 until flow is restricted to the bores 21. In modifications, Figs. 3 and 4 (not shown), the disc construction is the same except for the pads which are made of equal cross-sectional area but of different thicknesses in the case, and of equal cross-sectional area and thickness but not equiangularly spaced in the other case. Either modification offers a mode of operation similar to that of the embodiment of Fig. 2.

Title: Electronic timepieces
IPC: G04F10/04
Filed: 1975-07-10
Abstract: 1480548 Electronic timepieces SUWA SEIKOSHA KK 10 July 1975 [11 July 1974] 29119/75 Heading G3T [Also in Division G4]  An electronic timepiece comprises a time standard oscillator, quartz crystal controlled, a binary f divider chain feeding at least one counter chain, for driving a time display and a chronograph display respectively, and at least one of the counter chains includes a variable frequency divider counter 12, Fig. 6, which produces pulses at approximately 10<SP>k</SP> Hz wherein K is an integral number,  and the effective frequency division ratio of which is automatically changed at selected instants e.g. it is changed from a 1/12 to a 1/13 divider alternately so that in a time interval integrally related to one second it will feed a predetermined number of pulses to the next succeeding counter stage 407, Fig. 6. In Fig. 6, pulses at 128 Hz from a divider chain 10 are fed to the variable counter 12 which feeds pulses at approximately 10 Hz to a chronograph counter chain 407 to 403 the content of which is applied to drivers 507 to 503 to drive an electrooptical chronograph display, the lowest unit displayed being 0.1 secs. A control gate circuit 13 detects the condition of counter 407 and responds by causing the divider 12 to operate alternately as a 1/12 and a 1/13 divider, whereby the counter 407 will have an output signal at exactly 1 Hz. The gate circuit 13 is adjusted to effect control satisfactorily provided that the crystal oscillator is within a specified tolerance range. Any frequency error #f in the quartz crystal 8 output with respect to a standard frequency, due to manufacturing tolerances, will thereby be negated. In Fig. 8, line M, 407, shows the counting mode of counter 407; line NC shows ten conditions from 1 to 10 and line CR shows the counting ratio of divider 12 in each condition. A cycle of ten conditions and therefore a cycle of changes of the division ratio takes place over a period in which 128 pulses are fed into 12. Fig. 11 is a detail of Fig. 6 circuit, a counter 15 corresponding to counter 407, a variable divider 16 to divider 12 and a control gate 17 to control gate 13. To change the effective division ratio, flip-flops 24 to 27 are reset to zero at appropriate instants, as illustrated Fig. 13, by reset pulses from an R-S flip-flop 32, 33 the states of which are switched by the outputs O (28), O (30) of a NAND gate 28 and a AND gate 30 respectively. As shown the reset pulses occur after divider 16 has counted up thirteen pulses and again after twelve pulses of its 128 Hz input IN, 16. The divider 16 in fact acts as a 1/12 divider only under conditions 3 and 8 as illustrated Fig. 12 (not shown) and as a 1/13 divider in the remaining eight conditions. The 128 Hz output of divider chain 10, Fig. 6, is also fed via an f divider 11 to a counter chain 106 to 101, to display time of day &c. on electrooptical display devices 306 to 301, the lowest unit displayed being one second.

Abstract: 307,367. Marks, E. C. R., (Bates Valve Bag Corporation). Nov. 1 1927. Feeding webs. - In apparatus for feeding webs, and particularly paper tubes having multiple folds such as shown in Fig. 7, the web is gripped adjacent to each edge by two series of members having gripping faces which grip the web along narrow bands adjacent to but spaced from the edges of the web. The web 23, Fig. 2, passing from a printing press or other source of supply passes over an adjustably mounted guide roller 75 to the feeding members which comprise pairs of opposed chains 21 carrying grippers 22 which engage the margins of the web between the fold lines. The entrance ends of the chains are further apart than the delivery ends so that the grippers do not engage the web before the opposing gripping faces are substantially parallel to one another so as not to injure the web. The upper runs of the lower chains are supported on guides 25 and the grippers of the lower runs of the upper chains are pressed resiliently on to the web by spring pressed guides 27. Any suitable means may be provided for driving the chains intermittently or continuously. The intermittent driving device described comprises a friction clutch mounted on the shaft 17 of the upper conveyers. This clutch consists of a disc 48, Fig. 4, keyed to the shaft 17 and carrying, in recesses 50, spring pressed rollers 53 adapted to connect frictionally the disc 48 with a ring member 43 loosely mounted on the shaft 17. The member 43 is oscillated by a pinion fast upon it connected through change gears with a gear on one end of a shaft 37, Fig. 2, which at the other end is provided with a pinion 36 engaging a gear quadrant 33 oscillated by a rod 32 from a convenient part of the machine. At the end of the feeding stroke of the quadrant 33 an adjustable stop 68, Fig. 6, carried thereby releases a latch 65 holding a brake member 60 which is then pressed by a spring 62 into engagement with a brake drum 59 on the shaft 17 so as to ensure cessation of the feed. The brake is released at the end of the idle stroke of the quadrant by the engagement therewith of a pin 64 on the quadrant.

Abstract: 1,089,904. Photo-electric photo-meters. PYE Ltd. July 24, 1965 [July 24, 1963], No. 29289/63. Heading G1A. In a null balance photo-meter, the sample and attenuator beams are derived from different light sources, and the intensity of auxiliary beams from the two sources are compared to control the relative intensities of the sources. Two beams 1, 14 of radiation from a spectrally variable source 12 pass, one through a sample and the other directly to a detector 19. Similar beams 2, 15 from an auxiliary source 13 comprising a filament lamp and an interference filter pass, one through an attenuator 25 and the other directly to the detector. Beam choppers 17 and 18 operate cyclically to direct to the detector the following beams: first quarter cycle, beam 14; second quarter cycle, beam 15; third and fourth quarter cycles; both beams 1 and 2. A synchronous rectifier 22 operating at twice the chopping frequency produces a signal indicative of the difference in intensity of sources 12 and 13 which is used to alter the current in lamp 13 or adjust an attenuator to equalize the intensity of radiation falling on the sample and attenuator 25. A second synchronous rectifier, 21 operating at the chopping frequency derives a signal indicative of the difference of intensity of the beams 1 and 2 after passing through the sample and attenuator respectively and this difference is nulled by readjustment of the comb attenuator 25, the position of which indicates sample transmissivity. In a modification the four beams 1, 2, 14 and 15 may be simulated by appropriate movement of the source and attenuator into and out of two beams.

Title: Pressure reducing valve
IPC: G05D16/10
Filed: 1928-10-11
Abstract: 323,286. Marks, Sir G. C., (Vapor Car Heating Co., Inc.). Oct. 11, 1928. Pressure-regulating and reducing valves.-In a pressure-regulating valve of the type used on locomotives for maintaining a supply of low pressure steam in a train heating system, communication between the high and low pressure chambers 9 and 10 respectively is provided by a ported main valve 19 and a concentrically fitted pilot valve 26, the latter normally functioning as the pressure-regulating valve whilst the main valve opens only during periods of abnormal demand. The stem of the pilot valve extends beyond that of the main valve and bears against a boss formed at the centre of a piston 34, the piston sliding freely in the cylindrical top cover of the unit. The underside of the piston is subjected to the pressure existing in the low pressure chamber. An extension of the stem on the lower side of the pilot valve head slides in a boss formed in a plug 12 closing the bottom of the high pressure chamber, and acts as a guide for both valves. A passage 86 leads from the low pressure chamber to a chamber 49 formed in a side extension of the main casing, this chamber being closed by a spring-loaded diaphragm 51 and a scnewed plug 66. The plug 66 carries a spring-loaded auxiliary valve 73 which controls the admission of steam from the high pressure chamber to the space above the piston 34, through the passages 76, 81 and 85; the end of the auxiliary valve stem bears against the diaphragm 51. When an excessive drop in pressure occurs (as at starting or when additional carriages are coupled up), the diaphragm 51 moves inwards, thus opening the auxiliary valve 73 and admitting high pressure steam to the chamber above the piston 34 which then causes the main valve 19 to open, thus permitting a flow of high pressure steam direct tc the low pressure chamber. The minimum pressure at which the auxiliary valve will open is determined by the compression on the spring 61, this being adjusted by the handwheel 60.

Abstract: 1,151,504. Reciprocating pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. July 15, 1966 [July 13, 1965], No. 29582/65. Heading F1A. An actuating slide for a windscreen washer pump is operated in one direction by the windscreen wiper motor and in the other by spring means, operation in said other direction being dependent on the release of a catch by a solenoid. As shown a slide 17 is moved to the left by power means engaging the end 18 and is urged to the right on the pressure stroke by a spring 16 in the pumping member 15; movement to the right is prevented by the catch 23. The slide 17 is movable to the left by an amount sufficient to disengage the catch 23 which is then close to the pole 22 of solenoid 21. If the solenoid is not energized then the catch reengages the hole 25 on the short return movement of the slide 17. If the solenoid is energized then the slide makes the full stroke under the influence of spring 16. In a modification the slide operates the pumping member, through springs, on the pumping stroke and the suction stroke is provided by a spring within the pumping member.
