Title: Salt glazing apparatus
IPC: C04B33/34
Filed: 1947-05-02
Abstract: 631,613. Salt-glazing ceramic articles. FERRO ENAMEL CORPORATION. May 2, 1947, No. 11908. Convention date, May 4, 1946. [Class 51 (ii)] A tunnel kiln in which ceramic articles are subjected to a salt-glazing process comprises a salt vapour generator which is removably supported with its discharge outlet connected to the vapour inlet of the kiln, the generator including a fuel burner in a combustion chamber having a wall arranged transversely of the burner outlet to prevent unvapourized salt reaching the discharge outlet. In the form shown, the kiln comprises preheating, burning and cooling zones, and the ware 7 is loaded on cars 1 provided with sealing means 9, 10 and supported on tracks 8. The burning zone has side chambers 3, 4 heated by burners 5, 6. The salt vapour generator S is supported by rollers 17 on tracks 18 with its discharge outlet 19 engaging a recess in the kiln wall 20 around the vapour inlet 2 which communicates with a vertical passage 11 leading to the chamber 3. The joint around the outlet 19 may be sealed with fireclay. The generator, Figs. 5 and 6, comprises an L-shaped chamber 22 having a burner port 24 which is fed with salt via a pipe 27, funnel 29, and trough 28 from a hopper 30 fitted with vibratory discharge apparatus 32. The salt vapour mixed with products of combustion from the burner 25 is directed through a right angle by the wall 26 of the chamber so that a separating effect is obtained and unvaporized salt collects on the walls of the chamber and is not discharged into the inlet 2. In order to restrict the effective salt-glazing zone, salt vapours may be withdrawn from the tunnel ahead of the vapour inlet 2 or between the inlet and the exit end of the tunnel through passages 15, 16 communicating with longitudinal ducts 13 and 14.

Filed: 1958-04-15
Abstract: 878,445. Driver's brake valves. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. April 15, 1959 [April 15, 1958], No. 11913/58. Addition to 739,785. Class 103 (1). A driver's brake valve of the graduated release kind has one portion 11, 13, 17, 18 determining a control pressure in accordance with the position of the valve, and a second portion 12, 24, 26 to reproduce a pressure in the brake pipe 23 proportional to the control pressure (in passage 16), the pressures being restored for brake release or maintaining an existing reduce brake pressure from a main source (in passage 20), and has a valve 33 operable by the brake valve in the graduated release zone to close communication 31 between the control reservoir and the main source, and an arrangement 35-37 by which closure is freely effected. The control pressure acts through passage 21 on diaphragm 12 to connect brake pipe passage 23 to exhaust passage 25 via stem 26 or to the main reservoir passage 20 via valve 24 to equalize the control and brake pipe pressures for positions of lever 14 in the graduated release zone and the release and running positions, a valve 22 in brake pipe passage 23 being opened by cam 23. The control reservoir is charged from passage 20 through passages 31, 32 but in direct release apparatus the passage 32 is closed by plunger 35, 36 operated by lever 37 and a cam 34 opens valve 33 except in the graduated release zone of lever 14; hence when used in direct release apparatus the control reservoir pressure cannot be increased with lever 14 in this zone. The passage 32 is opened for graduated release apparatus. In emergency applications valve 29 is opened by cam 30 to vent brake pipe passage 23 directly to exhaust passage 25. The valve may be used in vacuum apparatus.

Title: Improvements relating to electrical discharge means particularly pulse-generating means and blocking oscillators for use therewith
IPC: H03K3/16
Filed: 1945-05-11
Abstract: 621,781. Valve circuits. SPERRY GYROSCOPE CO., Inc. May 11, 1945, No. 11947. Convention date, May 11, 1944. [Class 40 (v)] A pulse generator for producing bursts of high-frequency oscillations, comprises a grid controlled valve having a resonant circuit connected in the lead to the cathode or other control electrode, and a pulse transformer having one winding connected between its anode and the positive H.T. supply and a second winding connected via a capacitor to its grid and the positive H.T. supply. The Figure shows a conventional blocking oscillator with the gridleak returned to a high potential to give stability of recurrence frequency. During the regenerative process, the tuned circuit 18, 19, 30 is prevented from oscillating by the damping effect of conduction, but when blocking occurs, capacitor 18 is left in a charged condition and damped oscillations occur in the circuit. During negative swings in cathode potential, valve 11 conducts again momentarily and charges the grid negatively by reaction through pulse transformer 12 to accentuate the damping which is adjustable by means of resistor 30. After oscillations cease, the charge on capacitor 26 leaks away in normal manner and the cycle is repeated. Valve 11 may be a pentode in which case the tuned circuit may be inserted in the lead to the screen grid. Fig. 5 (not shown), and synchronizing pulses may be applied from source 35.

Title: Image scanning apparatus
IPC: G03G15/22
Filed: 1961-04-04
Abstract: 986,268. Zerography. RANK-XEROX Ltd. April 4,1961 [April 4, 1960],No. 12003/61. Heading G2H. A zerographic apparatus comprises means for positioning any image of a multiple image document at a projection station for projection on to a zerographic surface, and means for selecting any one image for projection: In the apparatus shown (see in particular Fig. 3) a microfilm is moved on to a support 21, (121) and is then viewed by means of lamp LMP 1, lenses 22, 23 and mirrors 25, 26 on a screen 27. The mirror 25 may then be moved out of the light path and an image of the film 4 reflected by means of mirrors 30, 31 on to a xerographic plate in the form of a rotating drum 33 which has already been charged at station 37. The image thus formed is then developed by means of a shoot arrangement 48 operating with a toner dispenser 50, passed through a discharge station LMP 2 into contact with a transfer sheet 55 fed by rollers 56, 57, 58 and then past an image transfer station 59, after which, sheet 55 is stripped by an air jet 63 off the drum and fed by belt 46 past a fixing station 65 and up guides 66 to a holder 67. The drum is then cleaned by a lamp 77, a brush driven by motor M6 and a second lamp LMP 3. In order to position correctly a particular image on a multiple image film, relative to the projection means, the device partly shown in Fig.4 is used. The films are initially stacked in compartments 80-82 in a housing 16 and are held there by flanges at the bottom of each compartment. A film support 109 on a block 95 is slid into position beneath a particular compartment and is raised by piston 98. An electric switch 8-10 LS is thus closed by a lever 117 on block 95 which operates a vacuum pump below support 109 so that a film is sucked out of its compartment and may be carried on the slidable support to a position below support 121. The vacuum is then operatively transferred, by electrical means, to support 121 so that the film is then held on support 121 and support 109 can be slid away. The support 121 is connected by levers (not shown) to two cams controlled by the same motor so that when the motor is rotated by an amount determined by a dial on the apparatus housing the support 121 is moved by a certain amount in two mutually perpendicular directions to position a particular image on the film in the operating position. The support 121 is then moved, so that the image may be scanned, at the same rate as that at which drum 33 rotates by means of the device shown in Fig. 9. A motor M4 rotates drum shaft 176 and through gears 179, 180, clutch 182 and shafts 181, 183 a cam 184. This cam acting through cam follower 185 and lever 160 moves support 121. The initial movement of 121 causes, through an electric circuit (not shown), an air cylinder 128 to be energized and move the mirror 25 out of the light path so that the image can be xerographically recorded.

Title: Improvements in and relating to telescopic hinges for trunks, suit cases, attache cases and the like
IPC: A45C7/00
Filed: 1929-04-19
Abstract: 332,587. Deutsch, E., Sip÷cz, H., and Dix, P. April 19, 1929. Attaching h inge members to articles adjustably.-Telescopic hinges for suit-cases &c. of adjustable capacity are so constructed that after the hinged connecting bracket has been turned through an angle of 90 degrees or thereabouts with respect to the telescopic members, the detent can be freed from the rack by a slight pull on the telescoping parts, and vice versa, after the bracket has been swung back through such an angle the detent is locked to the rack and the telescopic parts cannot be separated. The construction shown in Figs. 1, 2, comprises an outer telescopic part d attached to the body of the case by a fixed bracket e, an inner telescoping part a, an actuating slide g, a doublearmed detent lever t, and a filling piece Z, the device being connected to a hinged bracket c attached to the outer part of the case by a hingepin b passing through elongated slots in the parts a and g. The hinge-pin is rigid with the bracket and carries a tooth p which, in the position of the bracket shown in Fig. 2, engages the squared end k of the slide g. In this position of the parts, a pull on the telescoping members causes. a slight motion of the inner slide relative to the part g and thereby, by reason of the ramp s, an outward movement of the upper end of the detent lever t which is carried by the part a. The effect of this is to cause the withdrawal of the detent tooth x from the rack f provided on the outer telescopic member, permitting free adjustment of the parts. The parts are returned to normal position by a spring 10, causing the detent to become again engaged with the rack. If the bracket c is turned back into the position shown in Fig. 1, any pull applied causes no relative movement of parts a, g, and the detent accordingly remains locked to the rack. In the modified construction shown in Fig. 11, a second pin 13 parallel to the pin b is provided in the bracket c and is adapted in the position corresponding to Fig. 2 to engage the turned over upper end 15 of the slide which is thus held while a pull on the part a causes disengagement of the detent lever t as before. The slide in this construction is made shorter. Specification 332,586 is referred to.
