Patent GB-475402-A (GB)
Title: Improvements in or relating to cigarette making machines
IPC: A24C5/32
Filed: 1937-06-17
Abstract: To prevent lateral movement of cigarettes severed from a continuous-rod and evenly spaced on a conveyer, as described in the parent Specification, the conveyer is shaped so as to form a trough for receiving the cigarettes.  The cigarettes drop into grooves in the links of a chain conveyer or on to a flexible tape, the edges of which are bent upwards as it runs along a grooved block.  The groove may diminish in size along the length of the block to enable the tape to become flat before the cigarettes are removed by a deflector or the tape may run through a short grooved block and be unsupported until it engages a flat plate adjacent the deflector.  In high-speed machines the cigarettes may be delivered on to the conveyer beneath a top guide.

Title: Installation for cleaning a grating
IPC: E02B5/08
Filed: 1974-04-17
Abstract: 1455402 Bar screen rake DR ING A SCHREIBER 17 April 1974 [18 April 1973 11 March 1974] 16869/74 Heading BID [Also in Division F1] A bar screen 3 in an open sewage channel 1 is periodically cleaned by a rake comb 7 which is moved from a rest position to positions II and III, then moved up the downstream side of the screen with its prongs projecting therethrough to position IV and then advanced horizontally to position V to drop the collected debris into container 24 and returned to position I. The comb 7 is mounted on an arm 16 which is pivoted at 11 to a second arm 29 which is pivoted at 8 to a fixed framework, and the various movements are effected by hydraulic or pneumatic rams 6 and 10 which are advanced or retracted in turn by delivering fluid thereto. The comb 7 has wheels 15 which engage in vertical tracks 12 to constrain the comb to move from III to IV, this movement being effected by retracting ram 6 and controlled 'by a pressure limiting valve 14 through which fluid is simultaneously displaced from rams 10 (duplicated in Figs. 1 to 3). This enables comb 7 to retract if it meets an obstruction in screen 3. Roller 19 similarly constrains the advance of arm 16 to position V. Arm 16 carries a pin 20 which engages abutment 21 to release comb 7 so that it can tilt to discharge debris at position V, a cam 22 normally holding the comb rigid with arm 16. The various movements of rams 6 and 10 are each initiated by the magnetic pistons of the other ram actuating magnetic field switches 9, 13, 18 and 25 on the cylinders, to control valves in the hydraulic/pneumatic circuits. In Figs. 4, 5 the screen is inclined and the arrangement of arms and rams different from Fig. 1, and control of each movement is by a central pressure switch monitoring the fluid pressure adjacent pressure fluid source 5 and an electric programme unit.

Abstract: 1392355 Acoustic delay lines LICENTIA PATENT-VERWALTUNGS GmbH 13 April 1972 [29 April 1971] 17055/72 Heading H3U A cylindrical electro-mechanical delay line 1 comprises a cylindrical filamentary core 2, e.g. of quartz or glass surrounded by an envelope 3, the core having a mean refractive index for propagation of mechanical energy higher than that of the envelope. The diameter of the core is preferably of the same order of magnitude as the wavelength of the mechanical waves so that only one or a few modes are propagated. Input and output transducers, may take various forms, Figs. 2-7 (not shown), e.g. the core 2 may have deposited on an end face a thin magnetic layer 4 which is oscillated by an electromagnet 5 to produce longitudinal waves in the core. Alternatively the transducer may comprise a conductive layer (8) and an adjacent fixed electrode. In third and fourth forms, a layer of piezomagnetic material (9, Fig. 4) or piezoelectric material (10, Fig. 5), of a thickness approximately equal to half the wavelength of the mechanical waves, is respectively energized by an electromagnetic coil or a pair of electrodes. In further arrangements transverse waves are excited in the envelope by an electromagnetic coil or a piezoelectric ring. In a method of forming the transducer layer 4, a photo-sensitive layer is initially applied to the end of the core, exposed to light passing along the core and is then etched. The transducer layer is then applied and ground or polished.

Filed: 1961-07-31
Abstract: 1,018,492. Drying solutions, slurries and pastes in spray evaporators. R. O. H. BULL. Oct. 31, 1962 [July 31, 1961], No. 17145/61. Headings BIB and B2F. Solution slurries and pastes are dried by subjecting thin films of the material, in a drying chamber 13, to vibrations in the frequencyrange of 5 kilocycles to 50 megacycles per second by means of a transducer 12, and contacting the fine droplets of material so formed with a countercurrent stream of hot air, introduced into chamber 13 through a duct 18 from a heater 17. The finely-divided solid product collects in the base of chamber 13 where it is withdrawn by a pneumatic or worm conveyer, while the moisture-laden air passes out of the top of the chamber. In the spraying device shown in Fig. 2, the liquid is fed from the base of compartment 22 over the wall 23 of a hollow cone 24 which is vibrated vertically by a transducer 25 motivated by oscillator amplifier 14. The thickness of the liquid film on wall 23 can be controlled by regulating the distance between the outlet end of compartment 22 and the wall 23. In a modification, particularly suitable for slurries and pastes, the hollow cone is replaced by a perforated plate suspended from the base of compartment 22 by rubber bellows. In another spraying device, the liquid is supplied to two curved elements on each of which a magnetostrictive transducer is mounted. The liquidto-be-sprayed may alternatively be led into a cylindrical transducer which is joined to a tapered discharge-tube. The transducer may also be of the piezo-electric crystal type or of the moving coil type. The spray drying of milk and of antibiotics is referred to.

Title: Indexing means for grinding wheel dressers
IPC: B24B53/08
Filed: 1965-04-23
Abstract: 1,038,435. Trueing grinding wheels. LANDIS TOOL CO. April 23, 1965 [April 27, 1964], No. 17157/65. Heading B3D. Apparatus for dressing a grinding wheel 15, Fig. 3, comprises a dressing roller 20 mounted for rotation in a plane normal to the plane of the grinding wheel and disposed so as initially to engage the grinding wheel by one edge, feed means 14 for moving the dressing roller relative to the grinding wheel for a dressing operation, and incremental actuating means for indexing the dressing roller. The dressing roller is mounted on a shaft 21, Fig. 2 (not shown), rotatably supported in bearings 50 in a housing 22 which is carried by a bar 24 in a slide 12 movable to and from the grinding wheel by an hydraulic motor 32. The slide carries a follower 31 having the same diameter as the dressing roller and engaging a stationary template 30 corresponding to the grinding wheel so that as a carriage 11 supporting the slide is moved by an hydraulic feed motor 14 over the machine bed 10, the motor 32 also acts to urge the follower against the template so that the roller dresses the sides and face of the grinding wheel, which may be used to grind a crank-pin. The shaft 21 of the roller has an extension 57 in a housing 25 which is mounted on housing 22 and supports a motor 55 having a disconnectable coupling with the extension 57, whereby the dressing roller may be continuously rotated if desired. The housing 25 encloses a one-way clutch 60 having a rotor 62 which has an arm 61 movable by a rod 65 connected to pistons 66, 67, rotation of the rotor in one direction causing balls 63 to engage and rotate the extension 57 and hence the dressing roller. A toothed collar 68 is secured to the shaft and a plunger 69 is urged by a spring 72 towards the teeth of the collar, the spring being insufficient to cause the plunger to prevent rotation of the collar during indexing. The plunger is urged against the collar by hydraulic pressure to prevent rotation of the roller during dressing. In operation, the operation of the motors 14, 32 are of the pistons 66, 67 and plunger 69 are controlled by a relay circuit controlling solenoid-operated valves. When a push-button is pressed to instigate a dressing operation, a solenoid moves a valve so that hydraulic pressure acts on piston 67 to move the arm 61 and rotor 62 in one direction and then on piston 66 to move them in the opposite direction to effect an indexing movement of, say, 6 degrees, to the dressing roller, fluid pressure then being directed to plunger 69 to prevent further rotation of the roller. The motor 14 is then operated to move the roller across the grinding wheel and back again, the follower and template controlling the path of the roller. The axis of the roller is inclined to an axis at 90 degrees to the axis of the bar 24 so that an edge of the roller engages the grinding wheel. As the roller wears, it retains its same diameter until the other edge is worn, whereupon it is replaced.

Title: Improvements in fluid pressure braking systems
IPC: B60T15/20
Filed: 1959-05-20
Abstract: 890,441. Fluid pressure brakes. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. May 20, 1959 [Aug. 20, 1958], No. 17185/59. Class 103 (1). A fluid pressure braking system has a relay emergency valve 20 controlling the admission of pressure to brake chambers 24, 26 from source 22 in response to a predetermined pressure drop in emergency line 28 and in response to pressure variations in service line 30, the valve having a chamber 34 containing emergency piston 38 constantly subjected to emergency line pressure and to spring 40, and a spool valve member 46 slidably engaging the walls of a chamber 36 and being movable in response to pressure variations in the service line in one direction to connect brake chambers 24, 26 with pressure source 22 and in the opposite direction to connect the chambers 24, 26 to atmosphere. On charging, a compressor charges main reservoir 10 and via emergency line 14, 28 and one-way valve 54, the auxiliary reservoir 22, the trailer brake cylinders 24, 26 also being charged via port 56, passage 82, ports 76 in skirt of piston 46, chamber 62 and lines 64, 66. When pressure reaches 40 p.s.i. piston 46 is moved to a lap position and at 60 p.s.i., the pressure in chamber 34 moves piston 38 until extension 46 abuts cap 50, the spring 74 then moving piston 46 to the shown position to vent the brake cylinders to atmosphere via ports 76, passage 78 and filter 80. On braking, the driver's valve 12 supplies pressure from reservoir 10 to lines 18, 30 and port 72 to depress piston 46 to register port 76 and passage 82 to connect auxiliary reservoir 22 to the brake cylinders, the piston 46 moving to a lap position when brake cylinder pressure corresponds to pressure in line 18, 30. On release of pressure in line 18, 30, spring 74 returns piston 46 to the release position. Should the emergency line 14, 28 break or leak, the loss of pressure in chamber 34 allows spring 40 to move pistons 38, 46 to the " bottom " position for full or partial brake application.
