Title: Wrapping tube sealing and separating apparatus
IPC: B65B51/30
Filed: 1965-06-16
Abstract: 1,072,287. Seaming non-metallic sheet material. FR. HESSER MASCHINENFABRIKA.G. June 16, 1965 [Aug. 18, 1964], No. 25407/65. Heading B5K. [Also in Division B8] A wrapper tube S containing articles G is sealed at intervals by reciprocating jaws 4, the upper jaw being associated with a knife (20), Fig. 2, and the members 4, (20) being mounted on crank bars 6, 7 comprised in linkages 1, 2 (duplicated at the other side of the apparatus) and operated through gear-wheels 12, 13 and 14, 15 respectively. Each crank-bar 6 is pivoted at its ends to arms 10, 11 on which are carried rollers 16 engaging stationary edge cams 17. The arms 10, 11 pivot on gear-wheels 12, 13, respectively. The crank bars 7 are similarly mounted, through further arms 10, 11, on their respective gear-wheels 14, 15. All the gear wheels are driven continuously via the wheel 15 from a gearing 3 which drives the tube feed mechanism synchronously. Due to a flat 19 formed on each of the edge cams 17, the crank bars 6, 7 carrying the jaws 4 and knife (20) are given a horizontal movement during a part of their rotation so that the members 4, (20) accompany the moving tube S. The knife (20) is operated to produce a draw cut by means of a roller (22) running on a fixed cam rail (21), Fig. 7, and is carried by pivoted arms (25), Fig. 2. The gearing 3 includes two pairs of eccentric wheels 27, 28 adjustable relatively to one another thereby enabling the speed of the crank arms' movement to be varied according to different sized articles.

Title: Improvements in or relating to selective printing devices
Inventor: PHILLIPS ALAN
IPC: H04L13/06
Filed: 1965-06-16
Abstract: 1,144,501. Selective printers. EXCHANGE TELEGRAPH CO. Ltd. 1 June, 1966 [16 June, 1965], No. 25566/65. Heading B6F. Type-carriages; electric signal input arrangements; letter-spacing arrangements.-A teleprinter in which type characters are selected in response to a telegraph code signal comprises a carriage 14, provided with a printing head 14 and mounted on a guide rail 19 for movement in letter spacing direction in response to a signal which causes a magnetic clutch 30 to be energized and to drive a toothed belt pulley 24 so as to displace the carriage through one letter space; thereafter the clutch 30 is de-energized and a magnetic brake 32 applied to hold the carriage in a fixed printing position. Carriage-retaining mechanism,-On completion of a line, a carriage return signal releases the magnetic brake 32 and energizes clutch 31 which drives the toothed belt pulley 24 in a direction opposite to the letter-spacing movement and at a rate which is 10 times faster than the latter movement. Sound deadening arrangements.-When the carriage 14 is a short distance from a carriage stop 34 a steel plate 35 on the carriage cooperates with a clevis of a magnetic proximity switch 36, which energizes the magnetic brake 32 to slow down the carriage and bring it to rest by disengagement of the clutch 31, which thereafter is energized once more to complete the carriage return. As the carriage approaches the stop 34 a switch 37 disables the magnetic clutch 31 and energizes the magnetic brake 32 which is held until print signals are received. Web feeding arrangements; line-spacing arrangements.-On receipt of a paper feed signal solenoid 8 is energized momentarily causing lever 9 to disengage the tooth 7 of a half-revolution clutch 11, and thus allow a feed roller 3 to rotate and in conjunction with spring pressed roller 4 to advance the second medium by one line space. Record medium is supplied from a roll 1 and the slack is taken up by a take-up roller 16 which is driven by a slip-clutch pulley 17. The record medium is guided by a roller 2, platen 5 and a further roller 15.

Abstract: 839,336. Bogie mountings. METALASTIK Ltd. July 7, 1958 [Aug. 13, 1957], No. 25596/57. Class 103(6) In a suspension system for resiliently supporting a railway vehicle on a bogie 7, Fig. 1, the weight of the body 5 is carried by side bearers 30 comprising a plurality of rubber discs 33, Fig. 3, bonded to metal interleaves 34 which are secured to the upper surface of sole bars 31 and by members 32 to the body underframe 6. so that vertical loads are carried by the bearers in compression and horizontal movements by the bearers acting in shear. Traction and braking forces are applied to the body 5 by a column 8 which projects from the underframe and which is secured to a plate 10, Fig. 2. The central portion 11 of the plate receives rubber bushes comprising inner and outer cylindrical sleeves 12, 13 with a rubber bush 14 therebetween and a pin 15 passes through a cuff 16 received within the inner sleeve 12, Column 8 and the assembly secured thereto lies within transoms 17 and a bracket 18 is secured to each transom to support a similar assembly comprising sleeves 21, 22 bush 23, cuff 20 and pins 19. Pins 15, 19 lie on the central longitudinal axis of the vehicle and a link 24 is secured between pin 15 and the next adjacent pin 19. Relative sideways movement between the bogie and body deflects the column 8 from the central longitudinal axis of the vehicle and carries the adjacent ends of links 24, which movement is restricted by flanges 26 of an inverted channel strut 25 extending over the links and between transoms 7. Small deflectors of the column 8 are resisted by the torsional resistance of the bushes and greater deflections by the compressive resistance. The bracket 18 may be supported from the body 5 and the plate from the bogie 7 in an alternative arrangement

Abstract: 211,526. Holliday, J. F., and Acres, C. M. Sept. 22, 1922. Grates.-In a travelling furnace grate formed of links jointed to transverse rods, a damaged or broken link is readily replaced by a link of the form shown in Figs. 1 and 2 adapted to engage the link rods bv a transverse movement thereto and to be secured in position bv looking means actuated by such movement. The replacement link 1 is provided with recesses 4 having slots 1<b> in the walls 1<a> to engage the link rods and cams 2 pivoted at 3, the cams being tapered so that they fit tightly in the recesses. When the came are open, the upper parts project into the space to be occupied by the link rods so that, when the link is placed on the link rods, the latter engage the cams and cause them to close and lock the link in position.

Title: Process and means for carrying out heat-exchange
IPC: F28D19/02
Filed: 1947-09-23
Abstract: 643,881. Regenerators for furnaces &c. UNION DES VERRIERES MECANIQUES BELGES SOC. ANON. Sept. 23, 1947, No. 25862. Convention date, Oct. 11, 1946. [Class 64(i)] An inert pulverulent material is caused to fall freely through a hot vertically ascending gaseous current of unobstructed cross-section and longitudinal section, the duration of contact between the material and gas being controlled by regulating the speed of the gaseous current, and the heated material being brought into contact with a substance to be heated. Two superposed chambers 2, 3 each provided at the top and bottom with an outlet 16 or 21 and an inlet 15 or 20 for the gas and an inlet 13 or 17 and an outlet 6 or 19 for the pulverulent material are each of the same width over a height which is substantially greater than the width, to form a drop-shaft for the pulverulent material. In the regenerator shown, a tower is divided into superposed compartments 2, 3 through each of which a gas flows, and through which sand is sprayed successively by distributers 14, 18 on to which the powder is fed by hoppers 13, 17. The two compartments are separated by two apertured partitions 4, 5 with dampers 8, 9 which are linked so that when one is closed the other opens. In a modification, the partitions 4, 5 and dampers 8, 9 are replaced by a constriction, escape of gas from one compartment to the other being prevented by automatic regulation of the relative pressures of the two gases. In a third form, this escape of gas is prevented by a liquid seal formed by the use of a powder which melts when heated in the upper compartment. A funnel which forms the bottom of that compartment dips into a cup in which the molten material collects. The material overflowing the cup splashes on the lower distributer 18 and falls as drops. The two compartments may be arranged side by side.
