Title: A Method for the Production of Chairs, Sofas etc. from Plastics Material.
IPC: A47C5/12
Filed: 1967-06-24
Abstract: A chair shell 1 or frame is constructed, in a one-step moulding process, in the form of a single hollow unitary body of plastics material, such as nylon, polypropylene or polythene. Preferably, a heated divided mould is partially filled with plastics material, which is brought to settle, in known manner, on all surfaces of the mould.

Patent ES-343246-A1 (ES)
Title: Process for the manufacture under pressure of gases which may be substituted for natural gases
IPC: C10G/
Filed: 1967-07-20
Abstract: Combustible gas, exchangeable with natural gas, is made under pressure by (a) cracking liquid and/or gaseous petroleum hydrocarbons on a weak catalyst, e.g. refractory oxides or silicon carbide, in the presence of steam, (b) purifying the basic gas produced, and (c) subjecting the purified gas to an auto-hydrogenation with a catalyst which includes a metal of the platinum group said cracking being performed alternately and successively in at least two series of reactors in one of which the cracking is carried out whilst simultaneously in the other series of reactors the used catalyst is regenerated by means of air and steam at the same pressure as that employed for cracking and the gases resulting from the regeneration being added to the cracked gas to obtain the basic gas, the autohydrogenation of which is carried out, after cooling, at the same pressure as that used for the cracking. In a modification the amount of air added during the regeneration phase is such that the gas leaving the regeneration reactors contains about 10 volume per cent of nitrogen and this gas is fed to the burners for heating the cracking and regeneration reactors. In the purification step (b) H 2 S is removed from the gas by passage through granulated iron oxide or zinc oxide, before this purification the gas may be washed with a liquid petroleum fraction. The effluent from the auto-hydrogenation reactor is recycled after cooling to the inlet of this reactor, alternatively a reactor having an internal cooling circuit can be used.

Title: Toy vehicles combined with plural tracks and loading and unloading means
IPC: A63H18/00
Filed: 1967-08-23
Abstract: A toy vehicle track set comprises two different tracks 5 and 7 for toy vehicles driven by rotating coil springs 9, 91 respectively set into the tracks and engaged by driving pins 10 projecting from the vehicle undersides, track 5 is traversed by carrier vehicles 6, and track 7 is traversed by transportable vehicles 8. The latter vehicles 8 can be loaded and unloaded onto the carrier vehicles 6 at a loading and unloading station, 16 and 15, respectively. The loading station 16 has an access ramp 19 at one end and the unloading station 15 has an exit ramp 17 at the other end of track 5 which carries the carrier vehicles 6, and the other track 7 runs at one end onto the access ramp 19 of the loading station 16 and at the other end onto the exit ramp 17 of the unloading station 15. The carrier vehicles may be a train comprising a locomotive 31 and railway platform wagons 30, 301, 3011 and the wagons are interconnected and coupled to the locomotive by coupling strips 36, and the transportable vehicles may be toy motor cars. The loading platforms 32 are roughly flush with the ends of the ramps 17 and 19, and like the ramps, have a slot 33 for accommodating the driving pins 10. The platforms also have tracks 34 for the wheels 35 of the toy cars 8, and the rear ends 52 which cooperate with the access ramp are slightly flared and the tracks near the leading end curve to the side to register with the end of the exit ramp. The front end of the leading wagon 301 and the rear end of the last wagon 3011 are provided with catches 37 and 38 respectively to prevent the cars from rolling off the wagons. The catch is released when the horizontal lever arm 41 of the cranked lever is raised since this causes the vertical end 40 to be lowered to clear the slot 33 for the pin 10. The rear catch is released by an abutment 53 which projects into the path of the catch when the rear wagon is backed against the access ramp, and the front end catch is manually releasable. For controlling the loading and unloading operations each ramp is provided with a catch 24, 25 for intercepting the motor cars and comprises a manually tiltable lever 28 having two relatively spaced projections 29 which are alternately tiltable into the slot 21 in the ramp for intercepting the driving pins 10 of the cars. The coil springs 9 and 91 may be rotated by a miniature electric motor and a source of power in a housing 11. A lever 12 permits the motor to be started and stopped, whereas levers 13 and 14 permit the drive to be selectively applied to one or both of the coiled springs.

Title: Method of and apparatus for machining articles
IPC: B24B9/06
Filed: 1970-05-11
Abstract: A method of forming a bevel on an article, such as a disc of silicon, comprises mounting the article in a fixed position, disposing a quantity of abrasive material on the surface to be worked, engaging the abrasive with a moving tool surface having a configuration substantially the reverse of the bevel to force the abrasive into contact with the surface of the article, and maintaining the pressure until the bevel is formed. In apparatus for carrying out the method, a tool 30 made of tool steel is mounted in the chuck 32 of a drill press and has its lower surface formed with a recess having a frusto-conical wall 34. The article, such as a silicon wafer W, is secured by wax to a support 40, and abrasive, which may be diamond lapping material, is placed as a ribbon around the periphery of the lap. The tool 30 is thus rotated and lowered to cause the abrasive to form the bevel on the wafer. A gauge having a diameter D may be used to check the size of the bevel. After the bevel has been ground, the lapping material may be wiped off the wafer with a sheet of paper, the paper burnt, and the residue collected so that the lapping material can be separated for further use.
