Abstract: Amethyst crystal for jewellery is prepd. by (i) growing colourless quartz crystals by hydrothermal temp. fall process at a high press. autoclave at quartz inoculating crystal plates oriented parallel to the crystallographic surfaces of the +ve (1011) or -ve (1101) rhombohedra, using crystalline quartz as charge material, and (ii) exposing the colourless crystals cultured to ionising radiation, takes place by charging the autoclave with aq. 4-7 (5) wt.% conc. K2CO3 or KOH contg. 50-30 g/l Fe, as metal, oxides or hydroxides, growing the colourless quartz crystals at crystallisation temp. 300-500 (360) degrees C, under press. 200-1700 (1500) kp/cm2 at a crystal growth rate of 0.05-0.5 mm/ 24 hrs., pref. at 0.1-0.2- and 0.2-0.4 mm/ 24 hrs. at insulating plates parallel to crystallographic surfaces of the +ve and -ve rhombohedra respectively. Process is easily repeated, crystals have a highly pure colour and are highly transparent, i.e. free from cracks. Crystals grown at plates parallel to surfaces of -ve rhombohedra are free from cracks, grow 2-3 times faster, and exhibit colour pleochroismus after irradiation.

Title: Wound dressing pack - includes inflatable plastics ring to hold bandage away from wound surface
Inventor: KUNZE MAX
IPC: A61F15/00
Filed: 1974-02-05
Abstract: Surgical dressing package with an air cushion comprises a small inflatable plastic ring, containing sterile gauze connected with surrounding muslin and bandage and contained in a closed package.

Title: Compensation for wow and flutter on FM recordings - involves arrangement of filters and operational amplifiers
Inventor: GROSS THOMAS ALFRED OTTO
IPC: G11B20/22
Filed: 1974-05-10
Abstract: The apparatus is applicable to many different media and the compensating network modifies the information read from the recording. This is of a frequency modulated form and the compensating network operates to equalize the sidebands and so to remove the effects of wow and flutter. The network consists of an amplifier, a high pass filter and a modulator. An output is produced from this and fed to a low pass filter, the output of which is modulated by the original tape output filtered at any low frequencies (up to 100 Hz). The output of this is modulated once more and transduced to the form required to give the compensation needed.

Title: Pneumatic hammer with reciprocating piston - has reversing valve and releaser to give operating hydraulic circuits
Inventor: CROVER STEPHEN EARL
IPC: B25D9/18
Filed: 1974-09-04
Abstract: Pneumatic hammer has a housing to which a tool head can be releasably attached, and on which is a releaser movable between a working and a resting position. A piston in the housing can reciprocate and drive the head; a reversing valve, with a plunger, reciprocates and has active end surfaces of different sizes and a channel from one end to the other. Hydraulic alternating circuits are produced within the housing, a first with a path from the input to the piston, moving it to its second position, and a second circuit, from the inlet to the reversing valve and, when this moves to its other position as a result, establishing a third circuit from the inlet to the piston, returning it to its first position. A fourth hydraulic circuit is then opened from the housing inlet to the reversing valve, to return this to its first position, so that the whole cycle can be repeated.

Title: Hairdressing comb with two combined combs - has toothed steel comb held in plastics or metal support
Inventor: GLEICHMANN WALTER
IPC: B26B19/06
Filed: 1974-11-23
Abstract: The hairdressing comb which is used for cutting hair has a steel cutting comb which is made by pressing tooth cutting and hardening and it is mounted on a support plate. This support can be made from plastics or by a metal such as aluminium or zinc. Alternatively the cutting teeth can be pressed or machined into a steel strip and this strip is subsequently embedded preferably into a plastics, aluminium or zinc holder plate by injection moulding, adhesive bonding or by other methods.

Patent DE-2459661-A1 (DE)
Title: Ceramic pipe flange joint - has protrusion on flange or pipe end preventing insert movement
Inventor: STUMPF WILHELM DIPL ING
IPC: F16L49/04
Filed: 1974-12-17
Abstract: The loose flange bears against the conical pipe end via an insert, which is prevented, from moving by a protrusion on flange and/or pipe end. The insert can be of elastic material (4). The design ensures that the flange ring (3) does not slide on the conical portion towards the pipe end when tightening up, or under the effect of temperature. Consequently shrinkage of the ring on cooling does not give rise to high radial forces. Furthermore, the choice of a suitable elastic material for the insert can have the effect of keeping the joint under permanent tension even on shrinkage, without any springs being needed.

Title: Drying apparatus for transformer oil - forming a permanent part or addition to the tank
Inventor: LEPPER WILHELM DR ING
IPC: H01F27/14
Filed: 1975-01-11
Abstract: The purpose is to eliminate the periodic removal of transformer oil for drying and degassing by providing built on apparatus for the purpose. It comprises a vacuum dryer which is permanently connected to the transformer tank. Typically the drier takes oil from the conservator and, after treatment, returns it to the tank. The equipment may be designed for continuous treatment of the oil, in which case it can require very little space. Alternatively it can be switched in and out depending on the water content of the oil, in which case some form of hygrometric monitoring equipment is needed for control.

Title: Miniature inductive coils formed by laser beam machining - with beam control by electro-optical methods and needing no mechanical parts
Inventor: KIRMAYER WILLIBALD DIPL ING
IPC: B23K26/08
Filed: 1975-01-14
Abstract: The miniature inductors or transducers comprises a magnetic core with an insulation layer upon which a conducting layer is deposited by appropriate means. This conducting layer is then formed into a winding by machining away unwanted metal using a laser beam. The cutting process can be simplified by replacing the accurate mechanical control of the workpiece, or workpiece and laser source, necessary for producing a successful coil by electro-optical deflection of the laser beam. The latter technique permits the use of digital control methods for positioning the beam as required, and mechanical moving parts are eliminated.

Title: Field-effect liquid crystal cell - with twisted nematic display has ion exchanger layers for ionized impurities removal
Inventor: OSMAN MAGED A DR
IPC: G02F1/1337
Filed: 1975-02-26
Abstract: A liquid crystal cell with field effect and with twisted nematic display has on the inside surfaces of the cell glass plates ion exchanger layers which cover the whole area including the electrode layer and removed ionised impurities. Each ion exchanger layer has an anisotropic structure to orientate the molecules of the liquid crystal layer in a defined direction. Method effects an electrodialytic cleaning within the cell itself. The conductivity of the liquid crystal is kept to a minimum and is maintained at that level by constantly renewed cleaning of any freshly produced ions. The cell can now be operated with d.c. which results in a considerably simplification of the driver electronics.

Abstract: A pneumatically driven goods delivery mechanism for an automatic vending machine is such that the goods magazine can be separate from the coin input and goods delivery section of the apparatus. It is suited to the delivery of spherical goods such as ice balls and the like. A pneumatic input feeds an air blast through a filter and duct past a switching mechanism at the foot of a roughly cone shaped magazine containing the goods concerned, in response to a coin input in a slot removed from the magazine. The duct delivers the goods to a release tray beside the coin input.

Filed: 1975-05-06
Abstract: The mill comprises a circular chamber to which material is introduced at the circumference (6, 5) and which has a central outlet (23, 24) for the material in a finer form. Jets (10) of air from a set of nozzles (9) at the circumference are directed tangentially to an imaginary circle (11) concentric with the chamber, to produce a spiralling whirlwind in which the grains distribute themselves, under the combined action of centrifugal force and air pressure, so that the larger grains move outwards and the smaller towards the centre. A variety of whirlwinds is provided by the use of interchangeable sets of nozzles, each directed tangentially to a different imaginary circle (11) (i.e. with different angles gamma). Each nozzle would be held in place and kept from turning by a lug (12) held by a screw (14).
