Title: Pricing system label reading and printing equipment - uses hand held printing device positioned according to markings on label
Inventor: WIPPERN GERHARD
IPC: B41K5/02
Filed: 1978-03-06
Abstract: The hand held label printing and dispensing device can be used for a pricing system where information on the labels is read by a machine at e.g. the cash desk in a supermarket. The label (4) can carry four marking lines (7) which indicate the area (8) to be machine read. These markings are monitored by an opto-electronic converter(9) mounted at the rear of the head of the device, behind the printing wheel (5). The user of the device can easily control the position of the printed characters between the markings (7). Alternatively, a coloured stripe across the label can indicate the reading zone. This can be a grid marking, with bars (10) indented in it, which can be sensed by a scanning member (11) incorporated in the head.

Title: Cutting gobs off continuous streams of glass - with gobs temporarily supported by swivel plates until start of cutting operation
Inventor: GUENTHER FRANZ
IPC: C03B7/14
Filed: 1978-04-21
Abstract: The glass stream flowing downwards out of a nozzle flows onto, and is supported by, a plate mounted on a swivel. When the required amt. of glass has collected on the plate, the stream is cut. Shortly before, or during the cutting of the gob, the plate is swung downwards in an arc, so that the gob can fall into a stationary or moving mould located under the glass feeder. During the descent of the glass, the plate can pref. be moved horizontally or vertically; and a sepn. agent may be used on the surface of the plate so the gobs do not adhere to the plate. The surface of the plate may have a suitable shape, e.g. it can contain a cup-shaped recess into which the gob falls. The glass can possess a low viscosity, but high speed prodn. of gobs can be achieved, e.g. more than 60 gobs/minute can be obtd. to feed a rotary glass press.

Title: Sorting of tin ores, esp. cassiterite, by flotation - where ore is crushed and subjected to reducing treatment prior to flotation, to increase yield of tin
Inventor: HOBERG HEINZ PROF DR ING
IPC: B03D1/001
Filed: 1978-10-24
Abstract: The ores consist esp. of complex, disseminated, prim. cassiterites, which are first crushed to a size suitable for flotation, and are then subjected to a redn. treatment at 600-1000 degrees C using the usual reducing agents, e.g. CO, H2, natural gas derivs., coal, coke or other solid fuel. The treatment results in >=20% redn. to metallic Sn on the surface of the ore; collector reagents are then added, and flotation is carried out at pH 4-9 so the tin ores are removed in the foam. Redn. is pref. for max. 1 h., esp. for 5-30 mins.; and the collector reagents are pref. xanthates, thiophosphates and phosphonic acids. The pref. activating agents are heavy metal cpd., e.g. Pb- or Cu- acetate. Disseminated cassiterites are very difficult to sort via flotation and tin losses of up to 50% can occur. The invention provides high yields.

Title: Individual monitoring security alarm system - requires individual to respond to and interact with, pre-alarm and main alarm cycles
Inventor: SPECHT ALWIN ING GRAD
IPC: G08B21/04
Filed: 1978-11-17
Abstract: A security monitoring system for defined areas provides a continuous check on the movement of individuals. The alarm controller is worn or carried by an individual and requires a specific response both while in the area and when wishing to leave. The main control stage has a start input, a reset and a stop. After a predetermined interval a prealarm stage is activated and a buzzer energised. After a further delay a signal is applied to the main alarm stage is activated and the alarm loudspeaker energised. The prealarm stage is suppressed by either the output of an infrared sensor or by pressing an acknowledge key. Only the acknowledge key switches off the alarm. In order to leave the area a pause key is actuated to cause a reset after a specified interval. This system can supervise work places on railway track work etc.

Title: Machine element alignment system for extrusion press - uses electromagnetic alignment beam and spaced photodiodes mounted on one machine element
Inventor: MARKWORTH MANFRED DR ING
IPC: G01B15/00
Filed: 1978-11-22
Abstract: The alignment system uses a coherent electromagnetic beam (20) passing between a source (12) and a detector, each carried by one of the machine elements (1, 2), such that the beam runs parallel to their maix axis. The detector comprises two quadrant photodiodes (13, 14) axially spaced from one another on one of the machine elements (2) with the photodiode (14) nearest the source (12) having a central aperture, for passage of the beam to the second photodiode (13). The output signals from the two photodiodes (13, 14) are used to provide transverse and angular positioning signals for aligning the machine element (2) which they are mounted with the beam (20) or vice versa. The beam (20) may also be used to measure the distance between the two machine elements (1, 2) for controlling their relative movement.

Title: Thermally insulated double metal profile - with magnetising strips holding profiles in position forming spaces filled with foaming resin
Inventor: BAYER JOACHIM
IPC: B29C45/14
Filed: 1978-12-13
Abstract: A thermally insulated composite section, particularly for windows, doors, fascias etc., consists of two metal sections joined by at least one insulating section fixed into grooves in the metal. In its prodn., the metal sections are positioned in fixtures, outer magnetic/magnetisable strips are placed on the groove webs and press down on the webs, the space between the grooves and strips is filled by injecting or casting a cold-setting resin, the strips are removed when the resin has cured, and the composite section is moved from its fixtures. Limited usage of resin, the composite can contain one ore more resin profiles or quite small cross-section, the metals are not damaged, scratched etc. in the process. The figre shows the fixtures for prodn., with top and bottom parts of e.g. aluminium, and with holes for applying vacuum to hold metal sections in position. These have longitudinal grooves. Metal sealing strips are placed in position and, by passing a current round the outer strips, they are magnetised and press inwards, so sealing off the spaces which are filled with foaming resin. When the foam has cured, the current is switched off, the fixture vacuum is released, and the fixtures are removed. If it is desired to convey the final prod. automatically the lower holes can emit compressed air to allow easy movement on an air cushion.

Title: Foundry cores made from amorphous fused silica and resin binders - esp. for casting the inlet and exhaust ports and water channels in IC engines
Inventor: CASPERS KARL-HEINZ
IPC: F02F1/24
Filed: 1979-04-26
Abstract: The outer parts of the mould are made of sand bonded with synthetic resin and/or bentonite; but the cores are made from a mixt. of amorphous fused silica, with particle size 0.04-0.6 mm, and any suitable synthetic resin binder. Conventional foundry cores are made from silica sand mixed with synthetic resin, but lack dimensional stability and result in poor surface finish on critical zones of the casting, e.g. inlet and exhaust ports. The invention increases the dimensional stability of the cores, so castings with accurate internal dimensions are obtd., and also permit the escape of gases evolved during casting.
