Title: Thermally insulating polyethylene foam or air-pocket foil - coated on one side with acrylate! glue for sticking on hot-house window panes or glazing films
Inventor: KRAHN PETER DIPL ING
IPC: A01G9/14
Filed: 1978-04-19
Abstract: Heat-insulating, protective, coating of window panes or films used to glaze plant conservatories is claimed. A transparent polyethylene foam film is coated with a synthetic resin adhesive on one side so that it can be fastened to the window pane or glazing film. The adhesive is a dispersion of an acrylate. The adhesive-coated film is covered by a silicone paper that is stripped off before application. A varient calls for a polyethylene quilted air-cushion type film instead of the foamed film.

Title: Earth reinforcement or protection sheet - has form of mesh of similarly undulating strips for perforated stiffened sheet
Inventor: SEE JACQUES LEON ALEXANDRE
IPC: E01C5/20
Filed: 1978-04-28
Abstract: The perforated sheet is a combination of two perpendicularly aligned similarly undulating strips (A, B) in geometric form and may be used to protect earthworks, e.g. to cover formations or to provide a temporary traffic bearing surface over weak ground. The fabric is ideally of synthetic moulded material but may be of stamped metal. In plan the sheet subdivides into equal conjunctive square elements (A, B), a strip of sinusoidal form occupying each square. Viewed in elevation the edge of the strip describes 180 deg. of sinusoidal curve in traversing the square i.e. comprises a peak (5) with half troughs (4, 5) on each side. The strips (A, B) on adjacent squares are at right angles to one another, and the ends of the arch forms may be open except for a top segment (6).

Title: Pulverised fuel combustion process - has low nitrous oxide(s) level and uses three phase combustion with separate air supplies
Inventor: MEHTA ARUN KUMAR
IPC: F23C99/00
Filed: 1978-08-25
Abstract: The process for combustion with low NOx prodn. is applicable to any fuel but partic. suitable for pulverised fuel. It uses a three zone chamber (10) with air supply from a blower (26). Fuel injection is through nozzles (20) pointing radially inwards and and downwards into the middle, de-gassing zone (12), using primary air controlled by flap valves (36). Sufficient energy is applied to carry the particles down into the bottom, flow reversal, zone (14). The secondary air is injected, also controllable (30), through further radial nozzles (22). Combustion of gases from both these zones is completed in the top zone (16) with tertiary air input again through nozzles (38) with valves (40).

Title: Pyrolysis appts. for elastomers - with inner revolving cylinder sealed against outer stationary cylinder
Inventor: ROHE KARL A
IPC: C10B1/10
Filed: 1979-01-26
Abstract: Appts. for pyrolysis of organic materials, esp. elastomers, consists of an outer stationary horizontal cylinder, insulated with rock wool, and an inner revolving cylinder with a central feed pipe which also acts as one of the bearings.

Title: Multiple projectile missile head - has hatches forming friction joints with projectile openings and ejected with them
Inventor: HOESSLE WOLFGANG VON DIPL ING
IPC: F41G7/22
Filed: 1979-05-19
Abstract: The missile head has projectiles axially one behind the other and ejected sideways from it at a predetermined time. These are accommodated in separate compartments and enclosed by a common outer casing. At the compartments (6) the casing (9) has ejection openings (10) for the projectiles between the supporting portions (8). These openings are closed by hatches (11) completing the casing and inserted under tension so as to form friction joints (13) with the edges. The hatches resist loads occurring during transit, firing and flight. The mechanism ejecting the projectiles also frees the hatches and forces them out of the openings.

Title: Tetra:bromo-1,4-benzoquinone prepn. - by treating hydroquinone with hydrogen peroxide and conc. hydrogen bromide soln.
Inventor: JENKNER HERBERT DIPL CHEM DR
IPC: C07C46/06
Filed: 1979-08-16
Abstract: Prepn. of tetrabromo-1,4-benzoquinone (I) comprises reacting hydroquinone (II) with HBr and H2O2 in aq. HBr soln. contg. ca. 62 wt.% HBr. (I) is an inter in the prepn. of dyestuffs, plant protecting agents and bactericides. (I) is also a component of flame retardant for many plastics. The process requires no catalyst, in contrast to the previous process which used a 48 wt.% HBr soln. The reactants and prods. are more soluble in the more conc. HBr soln., so less reaction medium is needed, which reduces energy demands and demands on the equipment. Only 3 times the stoichiometric amt. of HBr is needed, compared to 12 times, in the previous process. The vol. reaction medium needed in the previous process is 5-6 times as great as in the new process. Yields are over 90%.

Title: Dimensional change determn. of meshed network tissue - by imprinted circle with intersecting axes compared with transparent template
Inventor: WEISS ERICH
IPC: G01B11/16
Filed: 1979-08-17
Abstract: Shrinkage or elongation of meshed network tissue which is subjected to various finishing processes is measured by marking the tissue with a circle. This circle includes a centre with intersecting axes at right angles to each other, wich point into the longitudinal and transverse direction of the meshes, respectively. After each finishing process a transparent reference template with the same circle and markings is laid on the tissue, coinciding with its centres, and the two circles are photographed. This supplies quick information on any dimensional change during every finishing process.

Title: Hydrolytic decomposition of starch by heating with steam - under pressure, with the mask cooled before pressure release
IPC: C13K1/06
Filed: 1979-08-20
Abstract: Hydrolytic decomposition of starch in farm produce (A) comprises treating a mash consisting of (A) and, heated process water with steam under pressure, then holding the temp. for the required length of time (rest time), and cooling by flash evapn. The new feature is that the rest time is reduced by cooling before flashing. During this step the decomposition continues and the heat withdrawn is transferred to process water of the current or subsequent batches. Pref. the amt. of water used to cool the mash is controlled so that it is heated to over 100 deg.C and is stored under pressure, and then supplied to the mash; esp. 0.8-2 wt. times (the amt. of mash) of water is used. An appts. for this process is also claimed; it consists basically of a pressure vessel and attached heat exchanger for the water. This method of heat recovery reduced total heat demand by 40-60%; yields are improved, and adverse effects on prod. quality caused by caramelisation are avoided.

Title: Rolling bearing using disc to retain lubricant - has discs attached to outer bearing race by welding or adhesively
Inventor: BROSA ERICH
IPC: F16C33/78
Filed: 1979-10-27
Abstract: A ring disc (3) is welded to each end of the outer bearing race (6) to prevent the loss of lubricant occurring by centrifugal force. Instead of using welds, an adhesive can fix the discs (3) to the race (6). One disc (3) can be an integral part of the race (6), whereas the other disc is attached to the race (6) by welding or an adhesive. The outer race can be made of two parts (7,7'), which each possess an integral lubricant retention disc (5). The two parts are joined by a weld. This replaces conventional lubricant retention discs, which are located in bearings by spring rings, but do not retain lubricant when the bearings are exposed high centrifugal forces.

Title: Tetrazolo-and 6-azido-1,2,4-triazine-di:one - competitive inhibitors of uricase used to provide animal models in which hyperuricaemia- can be studied
Inventor: COHNEN ERICH DIPL CHEM DR
IPC: C07D253/075
Filed: 1979-12-21
Abstract: Tetrazolo (1,5-8) (1,2,4)-triazine -6,8(5H,7H)-dione of formula (I) and 6-azido-1,2,4-triazine-3,5(2H,4H)-dione of (I) can be prepd. by reacting 6-bromo-1,2,4-triazine-3,5 dione (III) with a metal azide. (II) can be prepd. by treating (I) with strong acid. (I) and (II) are competitive inhibitors of uricase, an enzyme which in most mammals, regulates the conversion of uric acid into allantoin. In humans and some primates uricase is absent and uric acid is the end product of purine metabolism. Increased uric acid levels in serum (hyperuricaemia) results in disorders such as gout and kidney stones. The use of (I) and (II) in laboratory test animals prevents the degradation of uric acid into allantoin thus providing animals in which hyperuricaemia can be shidred.
