Title: Improvements in or relating to self-charging hydraulic accumulators
Inventor: JEROMSON JAMES R
IPC: F15B1/24
Filed: 1959-02-26
Abstract: 871,264. Hydraulic accumulators. THOMPSON RAMO WOOLDRIDGE Inc. Feb. 26, 1959, No. 6737/59. Class 69 (2). A self-charging hydraulic accumulator for use in power steering and power brake systems comprises a cylinder 14 containing a main piston 19 connected on one side to a source of pressurized hydraulic fluid and on the other to an air chamber 18, and an auxiliary piston 27 coaxially movable with the main piston to compress air which is in a sleeve 26 secured to the cylinder and periodically supplied to the chamber 18 to replenish air lost therefrom. The sleeve is connected to atmosphere by a pipe 33 and a poppet valve 37 urged to the closed position by a light spring 43. The air in a chamber 34 in the sleeve is compressed by the auxiliary piston 27 when the pressure of fluid in a pipe 23 moves the main piston 19 to the right to compress the air in the chamber 18. The compressed air in the chamber 34 passes through a one-way valve 47 into a passage 44 in the auxiliary piston and, after several strokes and the pressure in the passage has risen sufficiently and the piston 19 has returned to the left reducing the pressure in the chamber 18, the air in the passage passes through a one-way valve 51 into the chamber 18. The movement of the auxiliary piston to the left reduces the pressure in the chamber 34 so that atmospheric pressure in the pipe 33 opens the valve 37 and air passes into the chamber 34. The cylinder 14 is coaxial with an outer cylinder 11 and the annular space 16 between the cylinders is connected to the chamber 18 by ports 17 so that equal pressure acts on the opposite sides of the walls of the cylinder 14.

Title: Improvements in and relating to water boilers
Inventor: SHORT RONALD VICTOR
IPC: F24H1/18
Filed: 1953-03-12
Abstract: 742,367. Hot-water boilers. STILL & SONS, Ltd., W. M. March 4, 1954 [March 12, 1953], No. 6830/53. Class 64(1). In a hot-water boiler comprising a water drum 10 in which the water level is maintained within predetermined limits A and B, e.g. by a ball valve 18 and discharge pipe 26, a pipe 30 extends down from an opening 28 in the lower part of the drum, then upwards to a height above the highest water level A, and then downwards to a discharge point 36 below the lowest water level B. A burner 42 heats the pipe 30 most intensely at a part so spaced from the opening 28 and discharge point 36 that the resistance to flow is greater towards the former than the latter. As a result, the heated water flows through the pipe 30 from the opening 28 to the discharge point 36. The pipe 30 is a helical coil connected at the top to the opening 28 and at the bottom to a pipe 32 which rises in the tank above the level A and is surrounded by a pipe 34 open at the bottom and closed at the top except for a small hole 40 for the escape of steam. A perforated hood 50 is provided over the opening 28. The drum 10 has a flue 14 and an associated baffle 54. Steam pressure in the boiler controls valves 20, 44 respectively regulating the rate of water supply to the drum 10 and the gas supply to the burner 42. Two or more pipe coils 30 may be provided, arranged if desired concentrically. Dimensions are given.

Title: Improvements relating to cloth piling pits and the like
IPC: D06B23/00
Filed: 1934-03-06
Abstract: <PICT:0431418/IV/1> <PICT:0431418/IV/2> Cloth piled in a pit for liquid treatment is withdrawn after the desired period of treatment by floating it upon or by water or liquor in the pit and drawing it through the bottom of or beyond a false bottom in the pit by a downward pull to a point approximately beneath the centre of that pile.  The process may be continuous, cloth being fed into and withdrawn from the pit simultaneously.  Where water is used to float the cloth in a non-continuous process, the water may assist the washing treatment, which may thereby be shortened.  In one form of apparatus, shown in Fig. 1, the pit a is divided into two parts by a partition b forming two spaces c, d in which draw-off rollers h, f are placed.  Rollers g near the bottom of the pit a support cloth which tends to fall to the bottom.  The plaited cloth is floated by passing water into the pit, preferably through the channel c, and is drawn off as shown, between rollers i.  In another construction, shown in Fig. 2, a number of floats r are secured to arms q pivoted at o, p respectively to side members k adapted to be guided in vertical channels on opposite sides of the pit.  The members k are carried by two endless chains t coupled together to prevent relative tilting movement.  Cloth guides 4 suspended from two cross-members 2 carried on two right and left-handed screw shafts 3 define the width of the pit available for the piling of cloth.  The cloth is withdrawn between rollers i and over draw-off rollers h, f near the bottom of the pit, and passes through a channel c as before.

Filed: 1939-03-03
Abstract: 527,219. Electrophoretic treatment of rubber dispersions. SEMPERIT OSTERREICHISCH-AMERIKANISCHE GUMMIWERKE AKT.-GES. March 3, 1939, No..7094. Convention date, March 10, 1938. [Class 41] In separating the disperse phase of or purifying or concentrating aqueous dispersions of rubber or rubber-like materials as described in Specifications 492,030, 505,752 and 505,753, the rate at which the particles of the disperse phase migrate towards the electrodes is increased by increasing or changing the electric charge on the particles by adding polar substances such as electrolytes, buffer solutions, emulsifying agents such as lipins, cholesterols, salts of cholic or choleic acids, or wetting- agents. In treating rubber latex, which contains negatively-charged particles, the negative charge may be increased by adding ammonia, or converted to a positive charge by adding acid or in an alkaline medium by adding cationic soap. The polar substances may be added to the liquid in the electrode compartments ; they diffuse through the diaphragm walls into the dispersion. The dispersions treated -may be those of rubber, whether vulcanized or not, guttapercha, balata, neoprene or the aqueous dispersion obtained by . polymerization of an emulsified mixture of butadiene and styrene.

Title: Improvements in and relating to Elecric Motor Controllers.
Inventor: HIRST JOHN ARTHUR
IPC: H02P1/06
Filed: 1917-05-18
Abstract: 113,046. Hirst, J. A., and Brook, P. S, May 18, 1917. Controllers, actuating-mechanism for; handles; with auxiliary switches.-The hand-lever of a controller has a limited movement independent of the controlleractuating movement and this limited movement actuates a switch which controls the main circuit. Release of the handle automatically opens the controlling - switch. The contact arm A has a jaw a<3> in which works an insulated crank-pin g<2> attached to a shank f<1> journaled in a support K. The handlever H is pivoted on a pin h<1> in a casing F on the shank f<1>, and its inner end has two jaws h<2> pivoted on studs p on a plunger P. The plunger carries a segmental plate p<2> to engage a projection on the arm of the switch T which controls the actuating circuit of the main switch, and a spring S<1> normally keeps the plunger in the position shown in Fig. 3 with the switch T open. When the handle is depressed, the plate p<2> is lifted and the spring t<4> closes the switch T to complete the main switch operating-circuit. Resistance may be cut out by rotation of the lever H in the ordinary way. A contact S on the arm A bridges the contacts s<1>, s<2> in the full " on " position of the arm and short-circuits the switch T, and a contact R on the arm A bridges the contacts r<1>, r<2> in the zero position of the arm. The contacts r<1>, r<2> are in the main switch-actuating circuit so that this can only be completed in the zero position of the arm. When the main switch closes, an auxiliary switch completes a maintaining circuit. The plate p<2> may be provided with ratchet teeth engaged by a pawl to prevent backward movement of the arm A while the switch T is closed.

Patent GB-814137-A (GB)
Title: Improved method and means for measuring phaseshifts of electric signals
IPC: G01R25/00
Filed: 1956-03-08
Abstract: 814,137. Electric tests; electric analogue calculating systems. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. March 8, 1956 [March 9, 1955], No. 7330/56. Class 37. [Also in Group XL (c)] The phase of an alternating voltage with respect to a reference is determined by controlling the phase of the reference so that after the two signals have been multiplied together and the product integrated over a definite period the output is zero. The Specification shows that under these circumstances the phase angle between the two signals is equal to the angle through which the phase of the reference has been moved. Fig. 2 shows an arrangement for comparing the phase of a signal applied at terminal 2 with that of a reference at terminal 1. The reference is fed through a phase-shifting arrangement 4, and the signals are multiplied together by an arrangement consisting of transformers 12, 14 and squaring circuits 13, 15. The arrangement is that the two signals are added in one transformer and subtracted in the other. After subsequent squaring one signal is inverted at 16 and the two resulting signals are then added. The combined output is then proportional to the product of the two signals. The product signal is then integrated by means of a D.C. amplifier 5 provided with a capacitive feedback circuit and the output signal fed to a servo amplifier 7 which controls servomotor 17 to adjust the phase of reference 1. The phase adjustment of the reference signal is indicated on meter 19. The reference signal may be of the form s = cos #t instead of s = sin #t. Instead of applying a single reference signal of form s = sin (#t) and introducing a phase shift of # so that the signal becomes s = sin (#t + 0) the signal may be formed as shown in Fig. 4 in which sin (#t) is applied to terminal 1 and the cos (#t) to terminal 25 while a cosine potentiometer 26 modifies the sine input and sine potentiometer 27 the cosine input. Thus the compound output is sin #t cos # + cos #t sin #. The servomotor 18 adjusts both potentiometers simultaneously. In a still further arrangement (Fig. 5) noises and transients are removed by means of a double arrangement in which the reference in one channel is sin (#t + # + #) and in the other sin (#t + # - #). The output of integrator 55 will be proportional to cos (α = # + #) where a is the phase angle to be determined. The output,of integrator 5 is proportional to cos (α - # - #). The Specification shows that the addition of these two signals produces a signal proportional to sin (α - 6) sin #. Sin # is a constant determined by offsetting the two phase-shifting devices 44, 54 and the output is therefore proportional to sin (α - 6) which is used to drive servomotor 18 and hence two phase adjusters. The use of the pair of channels means that noise appearing in both circuits is cancelled out.

Title: Improvements in or relating to apparatus for the suspension filing of sheet-like articles
Inventor: RUDAT GUSTAV
IPC: B42F15/06
Filed: 1961-03-01
Abstract: 980,919. Suspension files. OTTO KIND G.m.b.H. March 1, 1961, No. 7409/61. Heading B6E. A suspension filing cabinet of the type comprising a number of cross-bars 4-8 having filing pins 9, the cross-bars 4-7 running on guide rails 3 adjacent the top of the side walls of the cabinet, and adjacent cross-bars being releasably connected to each other, is characterized in that the first cross-bar 4 is coupled to the front wall of the cabinet, the front wall being hinged to the cabinet by its lower edge. The cross-bars 4-7 have inverted U-shaped cross-sections and have end-plates 11 secured thereto. The end-plates carry rollers 10 running in tracks in the guide rails 3. Each crossbar 4-7 houses two longitudinally slidable rods 14. One end of each rod projects beyond the associated end of the cross-bar and engages an aperture 16 in the end-plate 11 of the adjacent cross-bar. In the case of cross-bar 7, the projecting ends of rods 14 engage apertures in the guide rails. Handles are provided on the inner ends of the rods 14, whereby the projecting ends thereof may be withdrawn from the apertures 16 to release a cross-bar. The leading edges of the end-plates 11 secured to the cross-bar 4, have rollers 19 mounted thereon and extend into recesses 18 in the front wall of the cabinet. They are maintained in the recesses by coverplates 20. On releasing a cross-bar, the front wall may be pivoted about its lower edge to separate said cross-bar from the succeeding one and permit filing or removal of documents to take place. In a modification, Fig. 10, the endplates 11 of the cross-bar 4 are coupled to the front wall 17, by fixed pins 22 engaging slots 24 in said end plates. The latter have lateral flanges 21. A cranked arm 25 is pivoted on each pin 22 with its lower edge resting freely on a ledge 29. Thus the front wall may be opened in two stages as shown in dotted outline. At the first stage the filing pins 9 between two cross-bars are separated sufficiently to allow the documents to be viewed but not removed.

Title: Apparatus for sorting and distributing coins, tokens and other similar articles
IPC: G07D3/12
Filed: 1936-03-12
Abstract: 463,347. Sorting and testing coins; money-delivery apparatus. KARAVODINE, N. DE. March 12, 1936, No. 7526. Convention date, March 13, 1935. [Class 27] The entrance slot of an apparatus for sorting and testing coins and similar articles is provided between an inclined plate 4 and the upper edge of an inclined surface 3, the coins being swept in bulk up the surface 3 by hand and allowed to fall down the slot. The coins pass from the slot down a short incline 6 to a diameter sorting track 9, along which are placed at decreasing heights a series of deflectors 14a ... 14h which deflect the coins according to their diameter into passages 16 leading to different coin compartments 1. The deflectors 14 'have outwardly curved edges for engaging the coins, and are cylindrical about an axis coincident with the lower rail of the track 9. The upper end of the sorting track, adjacent the inlet, progressively increases in cross-section to avoid jamming of the coins ; a blade spring 13 ensures that they travel in single file past the deflectors. At 10, the lower rail of the track is sufficiently narrow to release overthin coins to a receptacle 12. Instead of passing directly from the deflectors 14 to the receptacles 1, coins of certain diameters may be first passed through a weight or thickness testing track in order that spurious coins, for example, may be rejected. A weight-testing track is provided with three deflectors similar to 14, and, beneath the first two, light spring- blades over which the coins roll. Underweight coins fail to depress the first spring-blade sufficiently to clear the first deflector which ejects them from the track. Correct coins similarly just engage the second deflector which ejects them to a coin compartment 1. Overweight coins pass the second deflector and are ejected by the third. A thickness-testing track has a single thickness-gauging slot in its lower rail, the coins passing through this slot, or to the end of the rail according to their thickness. The apparatus may be arranged for delivering change by providing in each coin compartment 1 an exit slot leading to a common channel for conveying the coins to a receptacle. Each exit slot is similar to the entrance slot of the sorting apparatus, and is provided with a curved surface up which the coins are swept by hand.
