Title: Improvements relating to servo-motor steering mechanisms for motor vehicles
IPC: B62D5/06
Filed: 1958-01-06
Abstract: 833,611. Vehicle power steering. DAIMLER-BENZ A. G. Jan. 6, 1958 [Jan. 12, 1957], No. 498/58. Class 79(5) A servo-mechanism to assist manual steering in a motor vehicle is controlled by a slide valve operated from the steering wheel by a transmitter member, the slide valve being influenced by at least one reaction ram, 'whereby the force applied to the steering wheel is kept proportional to the force at the road wheels characterized in that resilient means are interposed between the ram and the valve housing and means are provided for limiting relative movement between the reaction ram and the slide valve. The steering shaft 2 transmits its rotation from a worm through interposed balls 3 to cause a steering nut 4 to move axially along the shaft, at the same time operating a steering arm (not shown) through a lug 6 and ball joint 5. A rib 7 on the nut 4 engages a groove 9 on the valve spool 11 of the slide valve and is free to rotate circumferentially around the shaft 2 in response to small deflections of the nut due to the friction in the worm screw. The spool controls the flow of oil from a reservoir 12 and pump 13 in conduits 14, 18, 23, 27 and 29 leading to and from chambers 19 and 24 on either side of the piston of a servomotor 21 that assists the steering. The spool 11 has axial bores 31 and 31<SP>1</SP> connected to the opposite sides of its central land 44 by channels 30 and 30<SP>1</SP>. The outer ends of the bores house reaction rams 33 and 33' urged outwards by springs 32 and 32<SP>1</SP> and whose travel inside the spool 11 is limited by transverse pins 40 moving in holes 39. The outer ends of the rams bear against pairs of disc springs 34, 35, slotted to modify their stress-strain characteristics, and bearing against covers 37 and 37<SP>1</SP> attached to the valve casing 10. When the valve is operated to raise the pressure on one side or other 19 or 24 of the servomotor there is a corresponding rise of oil pressure in one or other of the bores 31 or 31<SP>1</SP> of the spool 11. Initially this pressure will be reflected as resistance to movement of the spool due to relative movement between the spool and the reaction ram 31 or 31'. When the pressure has risen to the extent that the pin 40 is at the outer end of the hole 39 the spool and the reaction ram will move together as a rigid unit. In this condition resistance to further movement of the spool is provided by the springs 34, 35 and not by the oil presure. Fig. 2 (not shown) illustrates an embodiment in which the valve spool is housed in a track rod and operated from movements of the lever arm.

Title: Improvements in supports for mine cages
IPC: B66B17/34
Filed: 1952-01-08
Abstract: 702,716. Mine cage supports. QUALTER, HALL & CO. (SALES), Ltd., and HITCHIN, H. Jan. 8, 1952, No. 681/52. Class 78 (3) A mine cage is supported whilst being loaded by adjustable means independent of the cage hoisting means and adapted to be engaged with the cage and to raise it to offset stretch in the winding rope so that rails or a platform thereon are in line with those on the loading platform. A rectangular framework 5 is suspended by a cable 8 running over pulleys 9 and connected to a double acting hydraulic ram 10 positioned adjacent the loading platform. The ram is connected to a further cable 11 passing over pulley 12 secured to shaft 13 carrying two pulleys 14 (not shown) from which are suspended counter-balanced weights 15. The hydraulic ram 10 may be replaced by an electric motor driving the pulley shaft 13. Arm supports or keps 6 pivoted on the frame are moved by cams 21, when the frame 5 is raised into a position to support the cage 7. The cage is then lifted, by the hydraulic ram or motor until the rails 22 are in line with rails 23 on the loading platform. When the bottom deck of the cage has been loaded, the frame 5 is lowered to allow the cage to be supported by its winding rope which is then lowered and the frame 5 is again lifted so that the keps 6 engage under the second deck of the cage 7 and the rails 24 and 23 are aligned. When the loading of all the decks is complete, the frame 5 is again lowered to disengage the keps 6 and the cage is supported by its winding rope and raised to the surface.

Title: Improvements in or relating to the preparation of steroid compounds
Inventor: LONG ALAN GIBSON
IPC: C07J75/00
Filed: 1959-01-08
Abstract: D 16-20-Oxo steroids are prepared from 17a -hydroxy-20-ox steroids by dehydration, the 20-oxo group being protected prior to the reaction by conversion to an alkoxyimino derivative from which the oxo group is subsequently regenerated by hydrolysis.  The alkoxyimino derivative is preferably formed by reacting the 17a -hydroxy-20-oxo steroid with a salt of a compound H2NOR, (R being an alkyl group of up to four carbon atoms) in the presence of a tertiary amine of pKa <7,6, e.g. pyridine, in a homogeneous liquid medium, and the dehydration step is preferably effected with thionyl chloride in the presence of a tertiary base or di-N-substituted amide below 4 DEG C., the subsequent hydrolysis being performed with a dilute acid.  Other oxo groups present may be protected, e.g. as their ketals, and if the alkoximino steroid contains free oxo groups the final hydrolysis is performed in the presence of an active carbonyl compound, e.g. acetone.  Preferred products of the invention are those having the general formula:  <FORM:0866730/IV (b)/1> wherein R1 is hydrogen or an acyl group and Y is a ketonic oxygen atom or a hydroxy or acyloxy group.  Examples detail the formation of the 20-methoxyimino derivatives of 21-acetoxy- 3,3-ethylenedioxy- 5a -pregn-16-en-11-one,3b , 21-diacetoxy-5a -pregn-16-en-11-one, and 21-acetoxy- 3,3-ethylenedioxy- 5b ,6b -epoxy-pregn-16-en-11-one, and their hydrolysis to the 20-ketones.  Specification 811,632 is referred to.

Title: Improvements in or relating to electric incandescent lamp envelopes
IPC: H01K1/56
Filed: 1957-01-10
Abstract: 822,757. Coating electric lamp bulbs internally. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 10, 1957 [Jan. 20, 1956], No. 960/57. Drawings to Specification. Class 39(2) [Also in Group XV] A transparent electric incandescent lamp envelope is provided on its inner surface with a translucent coating of finely divided material which is substantially white in colour and has an average coating thickness of at least 35 microns, a coating bulk density to true material bulk density ratio of from 0.018 to 0.043, and the product of coating thickness in microns and the coating density ratio is at least 0.9. The coating bulk density represents the weight per unit volume of the light-scattering material as coated and, in the case of silica applied electrostatically, the maximum coating bulk density, in grams per cubic centimeter, is 0.094 the silica thus having a fluffy or porous nature since the true material density is 2.2. In order to effect filament coverage with a minimum of light absorption the minimum permissible coating thickness should average 35 microns. In an example, with a coating thickness of 40 microns the coating material density ratio should be at least 0.0225, their product then being 0.9, as aforesaid. Preferably the coating consists of silica applied electrostatically. In order to enhance the light-scattering properties of the silica coating, it should preferably act as a getter for at least 0.4% of moisture, this property being derived as described in Specification 802,910, by baking the finely divided silica, prior to the coating operation, at a temperature of at least 200‹C. and not more than 625‹C. Finely divided light scattering materials other than silica may be electrostatically deposited in carrying out the invention, the coatings being deposited on normally transparent bulbs to the density ratio specified. Zinc oxide, magnesia and alumina most nearly approach silica in performance. In order to increase the adherence of the silica coating at the neck of the lamp, that portion may be steamed to densify it.

Title: Contact lens cast moulding and packaging
Inventor: SEDEN WILLIAM EDWARD
IPC: B29C39/26
Filed: 1993-07-29
Abstract: Contact lens is cast by polymerising a monomer in a cavity between a male mould and a female mould. When the moulds are opened, the lens remains supported on the surface. Cover is sealed onto the flange to form a package. Lens is cast with the male mould (12) facing downwards and female mould, which has an annular wall and flange similar to the wall and flange (22), is fitted piston-like with the male mould. Cavity is sealed properly and that the moulds retract to take up shrinkage when the lens is polymerised in a pressure vessel at, e.g. 0.2-1 bar. Surface is flame polished to ensure that the lens remains attached to the male mould when the moulds separate. Male mould is then inverted to face upwards and form an open container. Saline fluid is poured into the container to hydrate and ease the lens from the mould. Finally a removable lid is applied to the flange.

Title: Manufacture of semiconductor device, and the semiconductor device
Inventor: KIMURA HAJIME
IPC: H01L27/04
Filed: 1995-01-05
Abstract: PURPOSE: To suppress the occurrence of abnormality in formation such as a notch, etc., at the time of dry etching of a conductive film. CONSTITUTION: A conductive film 2 is accumulated on a wafer 1 through a patterned base insulating film 3. An insulating film 40, which hinders the charge supplied from above an marginal region 1a by etching seed at the time of dry etching of the conductive film 2 from flowing into the margin region 1a, is made on the surface of the margin film section 2a on the marginal region where an element on the periphery of the wafer 1 is not to be made, out of this conductive film 2. By the existence of this protective film 40, the charge from the etching seed ceases to flow into the marginal region 1a of the wafer, and it becomes hard for a needless electric field to be made in the vicinity of the interface between the conductive film 2 and the base insulating film 3 made under it.  Accordingly, the etching seed is bent in the vicinity of the interface between the conductive film 2 and the base insulating film 2, and abnormality in formation such as a notch, etc., can be prevented from occurring in the conductive film 2 in the vicinity of this interface.

Abstract: PURPOSE:To provide the structure and process for production which can form the thin interlayer insulating layers of the thin-film magnetic head and can prevent the damaging and shorting of conductive layers by overetching of the interlayer insulating layers. CONSTITUTION:At least one layer, for example, the 2nd layer, of the interlayer insulating layers of the thin-film magnetic head consists of a 1st insulating layer 5 consisting of, for example, Al2O3 and having recessed parts formed by the shapes of the underlying conductive layers and the 2nd conductive layer 5' consisting of, for example, SiO2 and filling the recessed parts mentioned above and is flattened by an etch back method consisting of reactive ion etching. The end point of the etching of this time is exactly and easily executed by the detection of, for example, an Al element, by which the insulating layers 5, 5' are formed thin over the entire part. The damaging and shorting of the conductive layers 4 by the overetching are prevented by selecting the low etching rate of the insulating layers 5.
