Title: Engine mounting
IPC: F16F1/362
Filed: 1962-10-01
Abstract: 1,009,788. Spring mountings. ROBINSON TECHNICAL PRODUCTS Inc. Oct. 1, 1962 [Oct. 10, 1961], No. 37060/62. Heading F2S. A trunnion mounting comprises a plurality of cylindrical cushions 28, 32, arranged radially of the axis of the trunnion and a pair of tubular cushions 34, 36 extending axially of the trunnion, the inner ends of the tubular cushions being crenelated to provide semi-circular pockets for receiving and securing the cylindrical cushions. In the construction shown the inner ends of the cylindrical cushions abut against the trunnion receiving sleeve 16 and their outer ends co-operate with shallow metal cups 44, 48 of a trunnion ring 22. The tubular cushions 34, 36 are clamped about the cylindrical cushions in annular depressions 30, 32 of two flanges 18, 20. The inner peripheries of the flanges 50, 52 pass over a reduced diameter portions of the sleeve 16, the portions being then rolled over to lock the flanges in position. The cushions may be fabricated from transversely crimped lengths of wire lying longitudinally of the cushions and crimped together. The lengths of wire may comprise separate pieces of wire joined at their ends or the parallel segments of a piece of wire turned back and forth upon itself. The tubular cushions 34, 36 are produced by pressing a cylindrically shaped cushion in a mould. Thus the material extending into a pocket of the cushion is more compressed than the material in the region between the pockets. The initial lengths of cushions are greater than their mounted lengths thus allowing a predetermined pre-stressing to be effected.

Title: Improvements in and relating to tubular heaters
IPC: F24H1/40
Filed: 1954-12-22
Abstract: 754,098. Tubular heaters. AKT.-GES. FUR TECHNISCHE STUDIEN. Dec. 22, 1954 [Jan. 18, 1954], No. 37070/54. Class 64(1). A heater, for heating the gaseous working medium of a thermal power plant to a temperature exceeding 600 ‹C. by using burning fuel as an external source of heat, comprises a radiation part in which the working medium flows through vertical tubes and the combustion gases flow in a direction parallel to the tubes, and a contact part in which the tubes extend across the direction of flow of the combustion gases, the arrangement being such that the working medium to be heated flows first through the tubes of the contact part and then through the tubes of the radiation part, the temperature of the tube walls in the contact part not exceeding 600‹C. Fuel oil is fed to a burner 4 through a duct 3 and is burnt in a combustion chamber 1, combustion air being fed to the burner through a duct 5. The resulting combustion gases flow vertically downwards from the burner, transmitting heat by radiation to vertical tubes 6 encircling the chamber 1, and then impinge in cross flow on the tubes 8 which form the contact part of the heater, eventually leaving the heater through the aperture 9. The working medium to be heated passes through the heater via the duct 10, the tubes 8, the vertical pipe 13 and the heating tubes 6, eventually leaving the heater via the duct 16.

Title: Method and apparatus for the antiskid braking of a vehicl
IPC: B60T8/1764
Filed: 1975-09-10
Abstract: 1484229 Aritiskid braking systems FIAT SpA 10 Sept 1975 [17 Sept 1974] 37258/75 Heading F2F A control device for an antiskid system comprises a comparator 12 which selects the lower of the sinusoidal output signal Fi from wheel speed sensors 11a and 11b and outputs a signal Fi dependent thereon which is then transmitted to a second comparator 6 which compares it with a reference signal Fo such that the brakes are released by control means 7 if Fi is less than or equal to Fo. The value of Fo is computed from the assumption that there is a wheel deceleration threshold at which skidding is likely and that the value of this threshold is linearly dependent on initial wheel speed and vehicle deceleration for a given time period such that where A, B and C are constants, d v  is the output of a vehicle decelerometer 10 and T 1  is the period of the wheel sensor output signal Fi. The reference signal generating circuits include a clock 8 and counting circuit 1 which process the signal Fi to give an output N 1  from counting circuit 1 proportional to the period T 1 , which is fed with the corresponding F i  value to memory 2 which stores and then passes on the signal N 1  to a "read only" memory 3 which generates a signal dependent on N 1  and d v  which is passed through multiplier and divider circuits 4 and 5 respectively to give an output from divider 5 for Fo of the form of the equation quoted above. When a brake release cycle begins a modified reference signal Fo* is generated which decreases linearly with time at a rate proportional to the deceleration of the vehicle at the moment when brake release was initiated such that the brakes are reapplied when the vehicle reaches a certain threshold speed represented by Fo*.

Title: Folding of sheet material
Inventor: LISTER SAMUEL WILLIAM
IPC: D06F89/00
Filed: 1965-09-01
Abstract: 1,112,933. Folding sheets. LISTER BROS. Ltd. 30 Nov., 1966 [1 Sept., 1965], No. 37375/65. Heading D1S. Apparatus for folding sheet material comprises a belt conveyor 1 movable in one direction in synchronism with a table 3 reciprocable under the lower run of the conveyor 1 and means for raising the lower run away from the table 3 during the return stroke of movement of the table 3. A slide 6 is movable in a vertical guide 5 fixed to the table 3 and rotatably receives a crank pin 7 mounted on a wheel 8 on a shaft 9. A cog wheel 10 on the shaft 9 is connected by a chain 12 to a cog wheel 11 on the output side of a speed reducing gearing 13 driven from a motor 14 via a coupling 15. Rotation of the wheel 8 is transformed into reciprocation of the table 3 on guides 4. A rack 16 on the table 3 meshes with a gear 17 on a shaft 18 carrying a gear 20 which meshes with a gear 21 on a shaft 19. Cog wheels 22, 23 are carried by the shafts 18, 19, respectively and are connected by shafts 24, 25 to two free wheeling cogs (not shown) carried by a shaft 26. The conveyor 1 is driven by a cog wheel 29 driven by a chain 28 from a cog wheel 27 on the shaft 26. The free wheeling cogs are arranged alternately to drive and free wheel during successive strokes of the table 3 so that the conveyor 1 is driven in synchronism with the table 3 but always in one direction. An end roller 30 of the conveyor 1 is rotatably mounted on a member 31 carrying a pawl 32 associated with a rack 33. A roller 34 on the rack 33 follows a cam 35 on the shaft 9. In operation, a sheet, e.g. a washed tea cloth, is placed on the upper run of the conveyor I and as the table 3 moves to the left of Fig. 1 a length of the sheet is laid between the lower run of the conveyor 1 and the table 3. When the table 3 completes this stroke a lobe of the cam 35 raises the rack 33 and the member 31 to raise the lower run clear of the length of sheet. As the table 3 moves to the right of Fig. 1 a fold is produced and a succeeding length is laid on the previous length. When the table 3 begins to move to the left of Fig. I the rack 33 and the member 31 are lowered, the member 31 to a lesser extent than the rack 33 because the lower run of the conveyor 1 contacts the folded lengths. As this stroke continues a third length of sheet is laid on the second length. The process is repeated for succeeding sheets and when a thickness of sheets has been built up equal to the spacing between adjacent notches, the pawl 32 engages in the next higher notch in the rack 33 as it is lowered. Eventually, the pile of folded sheets reaches a predetermined height and the member 31 opens a switch (not shown). A second switch (also not shown) associated with the table 3 is opened each time the table 3 completes its return stroke and the, table is stopped when both switches are opened.
