Title: Tungsten trioxide coatings for luminescent materials - suitable for use with zinc silicate activated with manganese
Inventor: BOLZ BRUNO
IPC: C09K11/02
Filed: 1974-10-24
Abstract: In a luminescent matl. enveloped with an oxide and used for cathode ray tubes, the oxide coating is tungsten VI oxide (WO3) deposited at 100-1300 degrees C. The luminescent matl. is pref. a silicate, esp. zinc silicate matl., but it may be an oxide, phosphate, borate, vanadate, tungstate or sulphate luminescent matl. The pref. process consists of mixing the luminescent matl. with powdered WO3 and heating for 10 mins. to 10 hrs. at 100-1300 degrees C. The mixt. pref. contains 0.1-90, esp. 28-38 wt% WO3. Used for e.g. adjusting the threshold value of emission of zinc silicate luminescent matls. activated with Mn. Good reproducibility can be obtd. even in the case of large batches, and the threshold value can be adjusted by varying the amt. of WO3 employed.

Title: Rotational speed control circuit - comprises integrating RC elements which are connected to negative feedback facility to avoid hunting
Inventor: RICHT OSKAR HUBERT
IPC: H02P7/288
Filed: 1975-04-14
Abstract: The speed control circuit is partic. an integrated speed controller with a keyed output signal e.g. Siemens type TCA-955. The output signal from the speed control circuit is fed to an integration element, specif. an RC network, and between this integration element and the true value, or control point, integration element, specif. an RC network, is connected a negative feedback circuit element. The output signal finally obtained from the switching stage of the circuit is not used directly to control the (rotational) speed of an electric motor, but is fed into an integration element where, to suppress hunting tendencies, part of the follow up signal is fed, via the feedback element, to the true value or control point integration element, where the signal obtained is then amplified and fed to the motor.

Title: Prodn. of drawings of complex objects - using isometric perspective and photographic reproduction of parts through cut out system
Inventor: KAISER HANS
IPC: B43L13/14
Filed: 1975-05-17
Abstract: Production method is for drawings of technically complex objects in isometric perspective with the object of reducing the demand for engineering drawing. The basic elements necessary to represent the object on the drawing are drawn in isometric perspective and are then brought to the scale required by the use of a photographic process and are then reproduced on paper. Following the paper reproduction those parts necessary for the drawing of the object are then cut out and are finally assembled with the use of an easily detachable adhesive. This method has the advantage of reducing the use of skilled draughtsmen.

Title: Extn. of uranium from phosphate ore - by reaction with oxalic acid and subsequent treatment with alkali
Inventor: WIRTH GERNOT DIPL CHEM DR RER
IPC: C22B60/02
Filed: 1975-07-17
Abstract: The ore is first reacted with a suitable organic acid, pref. oxalic acid and then treated in a known way with soda or sodium hydrogen carbonate as alkali, and the U is extracted from the resulting soln. The ore may also be heated with an aq. soln. of a strong organic acid or damp ore can be heated with the acid. The process replaces sulphuric acid extn. and is thus more economic. Oxalic acid is consumed in the process, avoiding a reclamation process. The oxalic acid is made from cO and NaOH at 380 degrees C and moderate press. to form Na oxalate, which is reacted with HCl to form oxalic acid and NaCl. The CO may be made from a suitably sited source of C, such as coal or peat. The prim. and sec. phosphate arising from the extn. can be converted to neutral phosphate by reaction with CaCO3 or by a heat treatment and this may be used as a fertiliser.

Title: Tertiary butanol prepn. by hydration of isobutene - in the presence of cation and anion exchangers
Inventor: MERGER FRANZ DIPL CHEM DR
IPC: C07C31/12
Filed: 1975-08-27
Abstract: Tert isobutanol is made by reacting isobutene with water in the presence of a strongly acid cation exchanger and an anion exchanger. Pref. the ion exchangers are in powdered and/or macroporous granulated form. Suitable cation exchangers are synthetic resin materials contg. SO3- gps., esp. ring sulphonated cross linked styrene-divinylbenzene copolymers. The anion exchangers may be of the pyridine type or those contg. -NR2, =NR or -N gps. where R is H or 1-5C alkyl gp. The presence of the anion exchanger gives higher rates of hydration than when using the cation exchanger alone. In processes employing powdered ion exchangers, the presence of the anion exchanger facilitates removal of the catalyst by filtration. Dehydration of the tert. butanol prod. gives high purity isobutene suitable for the prodn. of isobutene polymers. The wt. ratio anion- to cation exchanger is, e.g. 0.05:1 to 2:1, esp. 0.1:1 to 0.5:1. Hydration of the butene is carried out, e.g. at 20-120 degrees C, esp. 30-100 degrees C, and pref. at pressures of 1.01-30 bar with a wt. ratio water to isobutene of 0.3:1 to 30:1, esp. 1:1 to 15:1.

Title: Hand operated fruit juice extractor - has pawl and ratchet drive on piston which exerts high compressive force
Inventor: WEISENBURGER AUGUST
IPC: A47J19/02
Filed: 1975-10-08
Abstract: The juice extractor has an inner compartment (3) with a perforated wall (4) and a base (6) with a bayonet clip attachment (8). The fruit is placed in the compartment (3) where it is compressed by the piston (11) and the juice is forced into the outer compartment (52). The piston (11) is normally held in its upper position by the tension spring (19). The piston (11) is forced downwards by an upward movement of the lever (36) which drives the pinion (39) through the lower pawl (4). The pinion (39) meshes with a rack on the tubular piston rod (15). The upper pawl (44) prevents the pinion (39) rotating in the reverse direction but can be released by pressing the button (48).

Title: Injection moulded buttons in multicoloured patterns - from granulates plasticised and injected separately or as mixt.
Inventor: KRIPS AXEL
IPC: B29C45/16
Filed: 1975-10-31
Abstract: Multi-coloured buttons are moulded by injecting a plasticised mass of synthetic material such as polymethacrylic acid ester with a pigment giving the ground colour, into the mould cavities, and before the first shot has set, material without colour or with a different colour is added. Alternatively, differently coloured granulates may be plasticised together and injected or the basic coloured material may be injected first, to be followed by a mixt. of colours. A number of separate feed channels into the mould may be used, or the feed channels may open into the centre of the button which is finish machined when set. The process is simpler than stamping out from laminated sheets and gives more varied patterns than simple parallel stripes.

Title: Hand held optical reader for labels - passes groups of signals from light sensitive elements through logic
Inventor: REQUE STANLEY C
IPC: G06K7/10
Filed: 1975-12-10
Abstract: A two dimensional integrated circuit network of light sensitive elements is at least as wide as five elements, has an optical spacing designed to embrace the widest of the characters and is about three times higher than the elements. A logic matrix responds to successive elements of a two dimensional sub-assembly of input signals from the network and recognises a character at a high rate in comparison to the rate of movement of the reader from one character to the other. Successive groups of the input signals are passed through the logic matrix in a sense designed to simulate the vertical movement of the reader through the reading field carrying the characters at a rate equal to the rate of displacement of the high character recognition rates.
