The message bytes are entered into SR1 and SR2 in reverse order, Z k <SP>1</SP> first, from distributer 44 with a shift between each byte. After entry of Z 1 <SP>1</SP>, the registers are shifted once more as C 1 <SP>1</SP> is shifted into SR1 and C 2 <SP>1</SP> is shifted into SR2 so that they then hold the syndromes S1, S2 respectively. The number of shifts is counted by a counter B1 preset to (k + 1). A further y shifts are then performed, at the end of which S1 is entered into SR2 whch then holds S 1 (+ )T<SP>y#</SP>S 2 . A counter B3 gates out SR1 and SR2 after a further x shifts so that S1 and an error pattern e j =T<SP>x#</SP>(S1( + )T<SP>y#</SP>S 2 ) are passed to error corrector 68 which generates corrected bytes Z 1 -Z k . A further gating circuit 80 is supplied with S1, e j  and signals N 0 , N 1 , N 3  indicating no error, only one track in error, and more than two tracks in error respectively to detect a large percentage of uncorrectable errors. The check bytes C1, C2 are generated by a pair of shift registers SR1, SR2 similar to those shown in Fig. 3.

Filed: 1969-09-29
Abstract: 1282737 Moulding tyres GOODYEAR TIRE & RUBBER CO 29 Sept 1969 [30 Oct 1968] 47710/69 Heading B5A In a method of curing the material of a moulded article a hot liquid under pressure is placed in thermal contact with the material for moulding and curing it, and the liquid is then removed from the article and replaced by a hot gas under pressure. A tyre T is cured in a mould 16 by supplying high pressure hot water to the interior of a bladder 24 and discharging it therefrom by high pressure steam whereby the hot water is fed to a tank interior maintained above atmospheric pressure. A timer 34 controls the curing cycle and first opens a steam inlet valve 42 to admit pressure steam from a supply 46 and via nozzles 50 to the bladder and chamber 32 to force the tyre against the mould; the steam valve is then closed and a hot water valve 62 opened to admit hot water under pressure to the bladder and chamber from a water heater 64. A small quantity of hot water may circulate back to the heater via a drain valve 54 and a by-pass valve 74 during the main curing period. The hot liquid is discharged by opening a valve 82 leading to a header 84 and tank 86 maintained at above atmospheric pressure. When the pressure in the bladder and chamber decays to the steam supply pressure a valve 88 opens and steam is supplied to force the hot water more rapidly to the header and to fill the bladder and cavity with steam. After a pre-determined time the steam valve 42 and hot water drain valve 82 are closed and a vent valve 104 opened to exhaust the steam to atmosphere, after which the mould is opened and the cured tyre removed.

Title: Improvements in the manufacturing of composite pipes
IPC: B29C53/80
Filed: 1969-09-29
Abstract: 1,273,229. Composite pipes. REDLAND PIPES Ltd. 29 Sept., 1969 [30 Sept., 1968; 22 May, 1969], No. 47779/69. Heading F2P. A composite pipe comprises an inner core pipe 1 wound with a layer of filaments of reinforcing material 6 coated with resin. The horizontally mounted pipe 1 is rotated and draws bundles 5 of parallel filaments from bobbins 4 through a comb 7, around a guiding bar or roller 8, around one or more tensioning rollers 9 and around a further guiding bar or roller 10. The large diameter rotatable tensioning roller 9 dips into a bath 13 of liquid resin so that it is coated with a film of resin as the roller rotates. An adjustable scraper 14 ensures even distribution of the resin on the surface of the roller to obtain the required resin thickness on the roller to coat the filaments as they are passed around the roller. The angle of contact a of the filaments with the roller can be adjusted by the guide bars or rollers 8 and 10. A braking action is applied to the roller 9 by a device 12 to set the required tension in the filaments as the coated filaments are wound on to the pipe, the apparatus, mounted on a carriage 16, is moved along the rails 17 parallel to the pipe so that the filaments are wound helically. When a layer of filaments has been wound on to the pipe from one end to the other, the carriage 16 is moved in the opposite direction. When the required quantity of filamentary material has been wound on to the pipe 1, the resin is cured and the bundles 5 severed. In a modification, the braking action is applied to the roller 9 by an hydraulic pump which is connected to an hydraulic motor of smaller capacity which rotates the pipe 1 and a pressure relief valve is provided in the hydraulic connection between the pump and the motor. The core pipe may be of metal, ceramic material, plastics, asbestos cement or concrete based on normal cements or synthetic resins and the filamentary material may be of glass fibres, h.t. metal wire, carbon nylon, " Terylene " (Registered Trade Mark). Longitudinal reinforcements may also be incorporated.

Title: Internal combustion machines
IPC: F01L9/10
Filed: 1975-11-20
Abstract: 1499587 Fastener driving tool MAX CO Ltd 20 Nov 1975 [20 Nov 1974 17 June 1975 28 June 1975] 47887/75 Heading B4C [Also in Division F1] An I.C. engine for driving a power tool, e.g. a nail driver, comprises a cylinder 12 having a piston 14 with a nail-driving rod 142, the cylinder 12 being surrounded by a combustion chamber 15 and brought into communication therewith by the opening a valve 18 by means of explosion of an air-fuel gas mixture in the combustion chamber. Fuel gas is supplied from a reservoir 23 and pressurized air is supplied from a compressor 22 to a reservoir 21. The pressurized air is used to form an explosive mixture, to maintain the valve 18 closed and to scavenge the combustion chamber. To operate the engine a pilot valve 35 is moved upwardly, thus lifting a fuel/air control valve 36 against a spring bias and closing an exhaust valve 33. Compressed air enters the chamber 15 via a duct 46c whilst fuel-gas also passes (via regulator 24 and ducts 47, 46b) into the chamber, and as the pressure on both sides 362, 363 of valve 36 equalizes the valve 36 closes under the spring bias. A sparking plug 16 is fired causing an explosion and high pressure in the combustion chamber 15, which pressure lifts a control valve 28 and a sensing valve 50. The control valve 28 puts a duct 31 in communication with the atmosphere via a duct 30a and allows compressed air to escape from a cavity 191 enabling the valve 18 to lift and explosion gases to enter into the cylinder 12 to drive the piston 14 downwardly. Sensing valve 50 allows compressed air to pass from a duet 51 into a scavenging chamber 48 and along a duct 49, to lift open the exhaust valve 33; this venting exhaust duct 34 to atmosphere; and also to force down a spring-biased scavenging valve 383. Scavenging air passes along ducts 40, 41 through the combustion chamber 15 and out of the exhaust duct 34. A delay in venting the exhaust duct 34 and opening the scavenging valve 383 is obtained by adjusting the volume of the scavenging chamber 48 and the size of a vent 52 to atmosphere. As compressed air escapes through vent 52 the scavenging valve 383 closes. Compressed air forces down control valve 28 and valve 18 while the piston 14 is returned by a spring 14a. In a modification (not shown) the spring 14a is omitted and gases on the lower side of the piston are admitted to the combustion chamber, which gases return the piston to its upper position after a power stroke.
