Title: Apparatus for monitoring a sheet transport mechanism
IPC: G03G15/00
Filed: 1973-07-10
Abstract: 1413069 Sheet sensing devices in electrographic machines XEROX CORP 10 July 1973 [11 July 1972] 32862/73 Heading B8R [Also in Division G2] Sheets of paper, which have failed to be removed from a photoconductive belt 12 after transfer of a developed image therefrom, are detected by a photosensitive device 302 connected to a logic circuit 40 which both starts a pre-set timer 41 and energizes a rotary solenoid 303 that rotates a sheet deflector 306 to the position shown in dashed lines where it intercepts the sheet and guides it along a removal path towards a conveyer belt 32 leading to the fuser (not shown). The deflected sheet contacts an arm 310 of a micro switch 31 connected to logic circuit 40 that cancels the timer 41 and allows the machine to continue to run for a pre-set time long enough for the sheet to exit from the machine. Non-cancellation of the timer 41, due to the sheet not having been deflected, allows it to actuate the terminating device to stop the machine after the pre-set time which is slightly longer than that required for a deflected sheet to reach and actuate the switch arm 310. The machine may include a pressure sensing device in the suction extraction system connected to the cleaning brush housing 261, in case the sheet detecting or deflecting mechanism fails, which will detect any change of air pressure caused by a sheet being transported into the housing 261 and use the detection signal to immediately actuate the machine terminating device.
Patent GB-449443-A (GB)
Title: Improvements in the manufacture of artificial textile materials
IPC: D06M11/38
Filed: 1935-11-27
Abstract: Warps containing yarns of organic esters of cellulose are subjected to local saponification and thereafter woven into fabrics.  Warp print effects may be produced on the fabric by dyeing with a dyestuff having different affinities for the saponified and unsaponified portions.  When the saponification is superficial the fabric may be uniformly dyed by means of a dyestuff having affinity for organic esters of cellulose.  The warps may contain in addition to yarns of organic esters of cellulose, also other yarns, e.g. cotton, flax, reconstituted cellulose, cellulose ethers.  The saponifying agent may be applied as a paste containing a suitable thickening agent.  If superficial saponification is required, the saponifying agent may contain buffer or modifying agents such as soap, sodium acetate, or borax.  Substantially complete saponification may be assisted by the presence of swelling or softening agents, e.g. pyridine, acetone, ethyl and methyl alcohol, glycerine and the thiocyanates of sodium, potassium, and calcium.  After weaving and before dyeing, the fabric is treated with a weakly acidic medium to neutralize any alkalinity in the material, followed by a treatment with weak alkali, e.g. ammonia.  The fabric is dyed from a bath containing a dye or dyes having an affinity for the saponified portions, unsaponified portions, or both.  In an example, a warp of cellulose acetate yarns is printed with a paste containing sodium hydroxide, dried at 60 to 70 DEG  C., woven into fabric, treated with 0,2--0,5 per cent acetic acid or formic acid, water, and then with dilute ammonia or sodium carbonate, and dyed with cotton dyestuffs.

Filed: 1932-11-24
Abstract: 395,928. Burglar alarms. BOLTON, C. J., Garden Reach, St. Anthony's Drive, and LOCKETT, B. R., Glendowar, Eleanor Crescent, both' in Newcastle, Staffordshire. Nov. 24, 1932, No. 33226. [Class 118 (i).] Relates to alarms which are automatically operated by the forcible opening of a door and comprises the provision, in a lock of the pin tumbler cylinder or like type, of a cam mounted on the connecting bar of the lock and in engagement with a slidable pin controlling the actuation of the alarm, so that when the cam is rotated by turning the key to release the lock the pin is withdrawn from its operative position and the alarm is rendered ineffective. In the form shown the pin 8 is urged by a compression spring 11 into contact with the cam 1 and its outer end extends, when in operative position, between a roller 13a and a stud 14a on a pivoted trigger 12a adapted to engage the reduced part 37 of a firing pin 36. When the cam is rotated by turning the key 4 the pin is withdrawn by the spring 11 and the alarm is rendered ineffective. When the door is opened forcibly, the outer end of the pin 8 bears on the roller 13a and rotates the trigger 12a to release the pin 36 which descends under the action of a spring 38 and explodes a cartridge 44. The part 47 of the trigger is adapted, when the trigger is rotated, to complete a circuit through a contact 48 to light signal lamps or sound a siren. The pin 36 and cartridge 44 are mounted in extensions 6a, 6b of the hasp. The upper end or the pin 36 is internally threaded so that a stud 42 can be screwed into it to prevent accidental discharge of the alarm. In another form the pin 8 is adapted to operate a rotary switch so that when the door is forcibly opened a circuit is completed to fire a detonator attached to a cartridge

Title: Improvements relating to speed control of direct-current motors
Inventor: MCTAGGART JOHN
IPC: H02P7/06
Filed: 1953-11-30
Abstract: 748,853. Automatic speed control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 30, 1953, No. 33241/53. Drawings to Specification. Class 38 (4). The invention relates to systems of the kind in which the speed of a D.C. motor is controlled in accordance with the difference between its terminal voltage and a reference voltage, by varying the supply to the motor armature (e.g. from a Ward-Leonard generator or gridcontrolled rectifier); the field of the motor being supplied from a substantially constant source. According to the invention a further control signal is provided to compensate for changes in the motor field current due to variations of the supply or variations in resistance of the field winding. As described with reference to a Ward- Leonard system, Fig. 4 (not shown), the compensating signal is obtained from the voltage drop across a resistor in series with the motor, field. Alternatively the motor field exciter may be automatically controlled in accordance with the field voltage and current, Figs. 6 and 7 (not shown), and the speed control reference voltage taken from the field-exciter. Specification 748,841 is referred to.

Title: Improvements in or relating to electrical indicating means
Inventor: HAYMAN BERNARD MAX
IPC: G08B5/36
Filed: 1960-09-28
Abstract: 918,870. Signalling by visible signals; signals for road traffic. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 1, 1961 [Sept. 28, 1960], No. 33250/60. Class 118. [Also in Groups XVIII and XXXI] A gaseous discharge lamp is connected into the electrical system of a vehicle so as to receive alternating current from the dynamo or interrupted direct current from the ignition circuit of the vehicle, means being provided to control the supply of current in response to some predetermined change of condition so that the illumination or extinction of the lamp provides a visual indication of this change. In Fig. 2, the lamp 3 is shown connected in parallel with a capacitance 6 and with a pair of electrodes 1, 2 across the contacts 5 of the circuit-breaker of a spark-ignition motor vehicle. The electrode 1 is in the form of a metallic liquid container, e.g. the brake fluid reservoir, and a circuit is normally completed between these electrodes by the liquid. Current flows preferentially through this path and the lamp 3 is normally extinguished but when the liquid falls sufficiently to uncover the electrode 2, current flows through the alternative path provided by the lamp which is thereby illuminated giving a visual indication of the fall in level. The lamp 3 may be connected in series with the electrodes (Fig. 1, not shown) in which case the extinction of the lamp provides the warning signal. In the parallel arrangement a test switch 7 may be used to break the circuit through the electrodes and thus to test the lamp 3. If the container is of electrically non-conductive material the circuit may be completed between two electrodes projecting into the container (Figs. 3 and 4, not shown) or alternatively the electrodes 1, 2 may be replaced in the circuit by a switch 10 (Figs. 5 and 6, not shown) which may be operated by oil pressure or other means such as a float.

Title: Improvements in rotary printing machines
IPC: B41F27/12
Filed: 1933-11-29
Abstract: 429,356. Printing-machines. HOE & CO., Ltd., R., and TURRALL, G., 109, Borough Road, London. Nov. 29, 1933, No. 33484. [Class 100 (ii)] A rotary printing-machine of the kind in which the printing-cylinders 1 are fitted with two or more sets of printing- plates which are secured between one pair of margin bars 3, 4, and other pairs 5, 6 displaced laterally and staggered circumferentially relatively to the first pair, is constructed so as to permit the cylinders to be driven in a reverse direction for printing on either side of a web already printed in one colour. The margin bars 5, 6, which as shown are arranged at an angle alpha in rear of the bars 3, 4 when the cylinder 1 rotates in the direction of the arrow, Fig. 3, can be adjusted so as to be the same angular distance in rear when the cylinder 1 is reversed, and in order that the impression cylinder 2 may co-operate with the cylinder 1 effectively in each position of adjustment, the cylinder 1 is fitted with two impression blankets 7, 8 of the width of the printing-plates, and these blankets are passed through one part of a continuous slot 9, 9<a>; 10, 10<a> respectively in the cylinder 2, the slots 9-10<a> leading to recesses 13, 14 in which are secured blanket anchoring means 15 and straining means 16, 16<a>. For one direction of rotation of the couple 1, 2 the blanket 7 is secured to the left of the cylinder 2 and is passed through the slot 9 which co-operates with the bar 3, and the blanket 8 is secured to the right end of the cylinder and is passed through the slot 10. For the reverse direction of rotation the blanket 7 is passed through the slot 10<a>, and the blanket 8 through the slot 9<a>. The portions of the slots 9, 9a; 10, 10<a> which are not fitted with blankets are filled up with filling-pieces 11, 12 formed with ribs 19, 20 which can be moved along transverse grooves so as to occupy either the right or left ends of these slots, and the pieces are held in position by pivoted locking plates 21, Fig. 4, secured by bolts 23. The driving-connection between the cylinders 1, 2 includes a pin-clutch which enables the cylinder 2 to be adjusted relatively to the cylinder 1 by an angle equal to the angle of stagger, and for this purpose a clutch as described in Specification 395,413 is preferably employed. By similar means the drive of the couple 1, 2 may be adjusted relatively to an associated couple to compensate for the difference in the length of the web-run between two couples which can be driven in the same or opposite directions. The margin bars 3, 4, 5, 6 could be constructed so as to be interchanged in the same manner as the filling- pieces 11, 12.

IPC: E03C1/242
Filed: 1922-12-07
Abstract: 208,368. Esperstedt, K. Dec. 7, 1922. Lavatory basin overflow and waste fittings. - The outlets of lavatory basins and the like are fitted with a number of dip-plate traps arranged in series in a circle round the waste pipe 13. The traps are formed by plates projecting alternately from the top and bottom of the fitting. Discharge is started by exhausting the air of the seals by means of a pump connected to the pipe 15<1>. The pump may be of the piston type or of the form shown in Fig. 6 which comprises sets of cylinders, 24, 25, the former being adapted to be raised by means of a handle 29. A special overflow is unnecessary as the seals are blown and the basin discharged when the water level therein reaches a certain height. A form in which the pump is dispensed with, the basin being discharged by raising a plug 37, is shown in Fig. 9, where the central pipe opens into the outlet 5.

A vacuum-sealing device comprises a member 11, Fig. 1, having a ridge portion 22 which is adapted to penetrate a sealing gasket 12 upon relative movement between the member and the gasket and which has at least one side 24, Fig. 2, making an acute angle (90 degrees-#) of 45 degrees to 75 degrees with the direction of the relative movement thereby providing for the exertion against the gasket of a force perpendicular to that direction, movement of the gasket in response to the force being restricted by means on the member 11. The gasket 12 which is annular and, as shown in Fig. 1, of rectangular cross-section is of soft metal, e.g. copper, and is inserted between opposite annular ridges 22 on annular flanges 11 brazed on a pair of hollow components of a vacuum system which are to be joined together. The flanges are secured by bolts and nuts 14, 15 which, when tightened, cause the ridges to penetrate into the gasket. Lateral movement of the gasket under the action of the force transmitted by the bolts is limited by shoulders 25 on the flanges, the gasket being trapped in the compartment 32 formed between the shoulders 25 and the slanting sides 24 of the ridges. The angle #, Fig. 2, is preferably 90 degrees. In a modification, the flanges have no flat base portions 21 extending inwardly beyond the face 23 of the ridges 22 and the angle # is slightly less than 90 degrees. In Fig. 4, a flange 11 has a pair of ridges 38, 39 of triangular crosssection forming between their slanting sides 41 a compartment 42 where the gasket is trapped. A slot 43 may be provided through the ridge 38 to provide gas access from the vacuum system to the compartment thereby preventing leakage between them if a good seal is not made with the ridge 38. Alternatively, a gas-access aperture is provided through the flange 11 to the bottom of the compartment 42. The aperture may be connected to a gas-pumping apparatus to maintain a vacuum in the compartment.
