Title: Seals for rotary fluid-machines
IPC: F01C19/08
Filed: 1976-04-23
Abstract: 1486753 Rotary positive-displacement fluidmachines CATERPILLAR TRACTOR CO 23 April 1976 [22 Sept 1975] 16656/76 Heading F1F In a Wankel-type machine, which may be an I.C. engine, axial sealing-strips 24 have recesses 34 extending into the outer surfaces 28 from each side and disposed along the length of each strip so that the recesses on one side alternate with those on the other side, the sum of the widths (across the strip) of any two adjacent recesses on opposite sides being substantially equal to or greater than the overall width of the surface 28. This arrangement is said to improve lubrication of the surface 28. The oblique edges of the recesses may be orientated so as to deflect the lubricant towards or away from the sides of the strips. A generally similar sealing strip, Fig. 5, for the periphery of the rotor of a machine of the nutating-piston type, Fig. 4 (not shown), has arcuate recesses 126, 128 in place of the recesses 34. The recesses on one or both sides of each strip may extend from top to bottom of the strip.

Title: Raster process for classifying characters
IPC: G06K9/64
Filed: 1971-05-24
Abstract: 1326141 Character recognition systems ARTHUR KLEMT KG 24 May 1971 [27 May 1970] 16672/71 Heading G4R A system for recognition of m classes of characters (e.g. for 10 numerals m=10) in which the characters in any one class may differ one from another (e.g. as in handwriting or in different fonts) includes a matrix of n points on to which the character is imaged. The number n is small, e.g. 24. For the recognition of each class of character there is a respective group of n or less than n mutually independent resistance networks. Fig. 2 illustrates an arrangement for recognizing the numeral 1. It comprises a group of 15 resistance networks N 1 KL1- N 15 KL1. If the matrix points are denoted by numbers 1-24 as in section a then the net-  works receive signals from those points indicated numerically and diagrammatically to the left of the networks in sections b-d. The points employed in section b are those which, for the various different forms of numeral 1, are usually black. Those in section c are those which are never blackened. In section d each network receives signals from points which should have the same degree of blackness. The outputs of the networks are normalized at R 1 -R 15  and fed to a comparator V associated solely with this group. Only if each of the networks provides a signal of sufficient magnitude does the comparator provide an output indicating that a numeral 1 has been recognized. The reference level of the comparators is adjusted in accordance with the thickness or blackness of the character by a signal derived at A 1-24  representing the sum of all the signals from the 24 matrix points.

Title: Improvements in and relating to reduction gearing
IPC: G04B13/00
Filed: 1936-06-16
Abstract: 478,355. Cams; ratchet gearing ; toothed gearing ; clocks ; counting - apparatus. RAWLINS, G. H. V., LACKING. TON, S. H., MANNING, W., NUTTER, R. T., and KENT, E. C. June 16, 1936, No. 16727. [Classes 80 (i) and 80 (iii)] [Also in Groups XVIII and XIX] Reduction gearing comprises a two-armed lever 16 provided with pins or tooth-engaging elements 17 adapted to engage and disengage the teeth of a gear 15 to be driven, the lever being displaced longitudinally by an eccentric or cam 13 and rocked by an eccentric or cam 12 to impart intermittent driving impulses to the gear. Means are provided for nullifying the movements of the eccentrics or cams which are unnecessary for the longitudinal and rocking movements, and stop means are provided for limiting the rocking. In the form shown for driving a clock from a synchronous motor 10, the eccentric 13 carries a strap 18 with arms transversely slidable in the lever 16 to produce the longitudinal movement, and the eccentric 12, which is spaced 90‹ from 13, engages spring-arms 19 to pro. duce the rocking movement. The pins 17 engage the teeth of a 120-tooth driven wheel 15 and align them with the teeth of a fixed wheel 14 provided with 118 teeth (or 59 double teeth). The lever 16 is provided with a slot 23, the sides of which touch the spindle 20 to limit the rocking movement. The motor 10 rotates at 120 r.p.m. and thus drives the gear 15 at such a speed that a 2 : 1 reduction gear 26, 27 is heeded between it and the minute arbor 28. The normally-fixed gear 14 and spindle 20 may be rotated by a knob 30 to set the clock. In a modification (not shown), one of the pins 17 may be arranged to slide in a fixed slot while the other acts as a driving member for a single driven gear. According to the Provisional. Specification, a four-armed lever may be employed which is gyrated about a driven gear by the two eccentrics. The invention may be applied also to pendulum clocks, electric rotary switch mechanism, recording mechanism and registering mechanism.

Title: Amusement device
IPC: A63G7/00
Filed: 1925-07-01
Abstract: 248,240. Sherry, J. A. July 1, 1925. Roundabouts.-Cars 42 drawn by arms 6 carried by a rotating member 2 are enabled to move along the arms under the control of the passengers. A wheel 10 on the end of each arm runs on a track 11 and drives a chain 19 which has upper and lower runs, as shown in Fig. 5. A carriage 22 runs along the arm, being guided by rollers 23, and carries a pair of levers 25 which are connected by a link 26. The pivot of one lever 25 carries an arm 2 having pins 30 to connect with either run of the chain 19. The steering-rod 59 of the vehicle is connected by gearing and a chain 53 with an upright shaft 35 on the carriage 22. A collar 36 on the shaft engages frictionally with a spring-pressed arm 37 which has a slotted connection with a pin 41 on the link 26, so that a movement of the rod 59 throws over the levers 25 and reverses the radial movement of the car. Stops 20, 21 on the arm 6 also reverse the movement at the ends of the arm, overcoming the frictional resistance of the arm 37. Instead of the cars being traversed by the rotation of the roundabout, the chain 53 may drive a pinion engaging with a rack on the arm 6, or the simple roller connection shown in Fig. 9 may be employed, the movement of the wheels 98 effecting the traverse. In all cases, the connection of the car 42 with the carriage on the arm 6 is by a link 91 having a pivotal connection 94 with a rod 96 which connects the axles 97 of the wheels 98.

Title: Improvements in fluid heaters
IPC: F22B1/04
Filed: 1944-09-06
Abstract: 608,849. Fluid-pressure servomotor-control systems. BABCOCK & WILCOX CO. Sept. 6, 1944, No. 17018. Convention date, Sept. 16, 1943. [Class 135] [Also in Group XIII] In a fluid heator (see Group XIII) in which a fluent mass of refractory material, flowing from an upper chamber 10 to a lower chamber 11 through a throat 42 and being returned to the upper chamber by an external conveyer, transmits heat absorbed from a fluid, e.g. combustion gases; flowing upwardly through the upper chamber, to a fluid flowing upwardly through lower chamber, automatic control means are provided to maintain a desired fluid pressure difference between the ends of the throat 42 to prevent leakage of fluid in an undesired direction through the throat, to maintain the temperature and/or pressure of the fluid leaving the lower chamber constant, and to regulate the air supply for combustion. To prevent leakage of fluid through the throat 42, the pressure at the top of the lower chamber 11 is maintained slightly above or below that at the bottom of the upper chamber by connecting those parts of the two chambers by pipes to a transmitter 80, which transmits the pressure difference to a differential-pressure recorder-controller 82, which also records changes of fluid flow in the inlet 52 to the lower chamber, these changes being transmitted by a transmitter 81. The recorder-controller 82 establishes an air pressure, which depends on the pressure difference and is transmitted through a selector valve, which permits a change-over to manual control, to a servo-motor 85 which operates a damper 19 in the outlet 18 of the upper chamber. The pressure at the top of the lower chamber 11 may also operate a diaphragm valve 108 in the steam inlet through a steam pressure controller 105, relay 106, and selector valve 107. When the heater is used for superheating steam, a temperature-sensitive element 100 in the steam outlet 54 operates a temperature recorder 101 which, through a standardising relay 111, a selector valve 112, and three-way solenoid valve 113, controls a diaphragm valve 110 which regulates the fuel supply to the burners. The supply of air for combustion is controlled by a control device 90 which comprises diaphragms 92, 93 operated by variations in the rates of flow of fuel and air for combustion. The diaphragms, through a bell-crank 91 operate a pilot valve 94 which controls a loading pressure which is transmitted to a relay 95 which establishes a control pressure transmitted through a selector valve 96 to a diaphragm valve 97 in the air supply. In other apparatus, the diaphragm valve 108 and associated parts are omitted, and the diaphragms 92, 93, instead of being subject to the rates of flow of air and fuel, are both subject on one side to the pressure in the combustion chamber 21 and subject on the other side one to the pressure of the fuel supply and the other to the pressure of the air supply.

Abstract: 1,086,484. Centrifugal separators; separating impurities from oil. B. STARZYK. April 22, 1965 [April 30, 1964], No. 17026/65. Headings B1D and B2P. In an oil separator, oil to be cleaned is fed, e.g. from an i.c. engine, under pressure through an inlet pipe 10 which opens tangentially into a chamber 6 occupying the upper portion of the separator casing and separated from the remainder of the casing interior by means of a partition 12 which has a number of deflectors 13 projecting above its upper surface and facing against the direction of circulation of the oil, Fig. 3. Due to the action of centrifugal force and gravity the relatively heavy contaminants move towards the chamber periphery and simultaneously sink to the lower portion of the chamber 6 whereas the relatively lighter clean oil moves towards the centre and is discharged through a pipe,11. The contaminants circulating in the lower peripheral portion of the chamber are trapped by the deflectors 13 and deflected downwards, with some of the oil, into a chamber 7 to circulate in vertical planes so that further centrifugal and gravitational separation takes place, the light oil returning to the chamber 6 through openings 14 in the partition 12 and the heavy contaminants passing successively into chambers 8, 9 via conical outlets 17 in partitions 15, 16 respectively and finally settling as sludge in the bottom of the chamber 9 from which they can be removed via a valve 5.
