Patent GB-671844-A (GB)
Title: Improvements in and relating to hairdressing
IPC: A61K8/20
Filed: 1949-09-12
Abstract: A process for imparting a permanent change in the configuration of hair on the living human scalp includes the steps of bringing the hair into the desired configuration, treating the hair with a reducing permanent waving solution and subsequently treating the hair with a chlorite solution.  As reducing agent there may be used a mercaptan, thioglycolate, or bisulphite.  An alkali metal chlorite solution may be used with or without additions of sodium carbonate, chloride, sulphate, mono- or di-sodium phosphate, boric acid, sulphuric acid, or other substances which regulate the reaction or adjust the pH value, which may range from 7 to 12. The proportion of mercaptan or other reducing agent may be up to 25 per cent of the reducing solution, and a solution of a chlorite in a concentration of 0.5 to 3 per cent may be used for the subsequent treatment.  The chlorite treatment may be effected at 20-100 DEG  C.  The hair, dry or moistened with a reducing solution, e.g. ammonium thioglycolate solution, may be wrapped on solid rods, and then saturated or re-treated with the solution.  It is then allowed to remain in this state at room temperature until tests show formation of wave ridges when a strand of hair is uncoiled.  The hair is then thoroughly rinsed by spraying with warm water, and is continuously treated for 3-5 minutes with a solution of a chlorite at 40-50 DEG  C.  The hair is unwound from the rods and again treated with chlorite solution. This solution may contain 10 grams of sodium chlorite, 0.63 grams of sodium carbonate and, if desired, 10 grams of urea per litre. Instead of winding the hair on rods, it may be coiled into pin-curls and suitably fastened.  Alternatively, the hair may be wound upon hollow curler rods and the various solutions and rinsing water are forced through the curls from the inside by means of a pump.  In another method of treatment, the curler rods are removed after the curls have been fastened in place.  The reducing solution may contain a mixture of reducing agents, e.g. mercaptans may be mixed with sulphites, or bisulphites.  The solution may also contain sulphates or carbonates.  Heating devices such as exothermic chemical pads and machine heaters may be used in the treatment.

Title: Tractors having power lift mechanisms
IPC: A01B63/112
Filed: 1965-06-03
Abstract: 1,113,681. Tractor power lift mechanisms. MASSEY-FERGUSON Inc: 3 June, 1965 [9 June, 1964], No. 23677/65. Heading A1P. A tractor power lift mechanism having a manual draft control lever 73 is characterized by a control 92 which is operable independently of the lever 73 to select the range of draft controlled by this lever. Signals originating from the movement of an attached implement are transmitted via the upper link 16 to a leaf spring 23 having a rod 50 engaging a cam surface 49 associated with the control 92. Lever 46 is thus pivoted about a fulcrum roller 80 to operate at linkage and move a link 61 having a one-way connection with a lever 36 operating the control valve 35. A lever 63 connected to link 61 is movable by a cam 71 connected to the manual lever 73. The control 92 is rotatable to move the rod 94 and thus the cam 49 longitudinally in order to vary the effective spacing between rod 50 and roller 48 on lever 46 to alter the range of draft force regulated by the lever 73. The sensitivity of the draft control is variable by movement of the fulcrum 80 for the lever 46 whereby movements of the upper link 16 affect movements of the valve-controlling linkage to a greater or lesser extent. This fulcrum roller is moved by a manual lever 84. The valve-controlling linkage includes three-armed lever 58 having an arm 58a arranged to engage an adjustable stop 76 when the mechanism is moved to the transport position, whereby the linkage is locked against movement by the draft control arrangement.

Title: Control device for machine for sub-titling of cinema films
IPC: G03D15/00
Filed: 1969-05-10
Abstract: 1,271,865. Programmed control of printing. FILMTEXT Ltd. May 10, 1969, No. 23946/69. Heading G3N. A control device for a machine for subtitling cinema films is controlled by a programme tape so that the stamping force is adapted to the size of the sub-title of the block. As shown, Fig. 1, a magazine 1 contains subtitle blocks 2 which are transferred individually by a cylinder 7, in accordance with a predetermined sequence, to a station 8 where they are held against a stop by a spring-loaded finger 10. The blocks are transversely pressed against a film 17 by a piston 11 to apply a sub-title. The transfer of a new block to the station 8 causes the previous block to be displaced to a position where a rod 12, in response to the movement of a piston 13 in a cylinder 15, deflects it into a magazine 16. The control device is operated pneumatically in response to the actuation of switches by a stepped slotted programme-tape. The control device, Fig.3, is fed with compressed air from a line L1 and the presence of a slot in the tape, not shown, selects a switch K2 causing closure of contacts to admit air through a valve V1 to displace a control piston valve 38 in a cylinder 37. Pressure is thereby applied to a cylinder 15, to displace the implemented subtitle, a pressure regulating device T and a line valve V4. The pressure regulating device T comprises a piston 30 which is displaceable under applied pressure to move a rod 31 to a limit of travel set by the selected switch K2 through a solenoid-actuated stop-lever 25. The piston 31 incorporates a rack engaging a pinion 33 connected to an eccentric disc 34 which adjusts a pressure regulator 36 through a spring-loaded arm 35. The regulated pressure, through the valve V4, is fed via a film-synchronized valve V5 to a cylinder 22 to depress the sub-tilting piston 11 against the pressure of a spring 23. The actuation of a switch K5 energizes a solenoid-valve V2, which vents the cylinder 37 and energizes a solenoidvalve V3 to displace a piston 37 displacing a slide 42 which causes pressure to be applied to the transfer cylinder 7.

Title: Process and apparatus for the production of pig-iron
IPC: C21B11/00
Filed: 1934-08-20
Abstract: 442,895. Producing pig iron. BARON, H., 231, Strand, London.-(Siemens & Halske Akt.-Ges.; Siemensstadt, Berlin) Aug. 20, 1934, No. 24023. [Class 72] [See also Group XII] Pig iron containing 2À4 to 3À2 per cent of carbon is produced by introducing amixture of iron ore and a sufficient quantity of carbon to reduce the ore and raise the carbon content of the iron so produced to the desired amount into a fused iron bath having a carbon content substantially equal to the amount referred to above, and which is heated during the addition of ore &c. The iron bath may be contained in an open hearth furnace heated by a flame produced by the combustion of coal dust or oil with air enriched with oxygen or in a tightly sealed electric furnace and the ore used may be fine grained ore such as slick and the carbon finely divided inferior coal. The phosphorus sulphur and silicon contents of the iron produced are reduced to the desired extent by renewing the slag during the reduction and, if necessary, varying the composition of the slag. The waste gases removed from the electric furnace may be used to supply additional heat to the furnace, the supply of electrical energy being varied as each fresh charge of ore and carbon is introduced into the furnace so that the iron bath is not subjected to any increase in temperature. The iron bath used may be produced by the fusion of any form of iron mixed with reducing agents in an open hearth or melting furnace and the fused iron transferred to the electric furnace. The waste gases from the electric or open hearth furnace may be used for preheating and partial reduction of the iron ore charge preferably in a rotary furnace. The ore charge is fed from a hopper 3 through a double valve 4 and a tube 5 into a rotary drum 6 the preheated and partly reduced charge passing by a tube 7 into the furnace 1 containing the iron bath. The gases from the furnace 1 pass upwards through the charge in the drum 6 and are removed by a fan 8. When an open hearth furnace 1 is used the parts 1<a> and 1<b> are lined with carbon bricks and the part 1<c>, at the level of the iron bath 2, is lined with magnesite or similar material. Part of the waste gases from the furnace 1 may be combusted with air or oxygen to provide additional heating for the interior or exterior of the drum 6 and another part of the said gases may be used for heating the furnace 1. A shutter 9 may be provided to close the end of the tube 7 when the furnace 1 is tilted to discharge part or the whole of the charge therein.
