Title: Introduced improvements in looms and in the process for the production of long-haired knitted fabric with thread loops on the inner face and the fabric thus produced
Inventor: TORRENS VALLHONRAT MANUEL
IPC: D04B9/14
Filed: 1987-12-09
Abstract: The subject of the further development is a circular knitting machine, by means of which pile fabrics or pile-like knitted fabrics are to be produced. The production of knitted fabrics of this type conventionally takes place by the formation of a mesh-like ground fabric (11), to which are fed, via cards (9), fibres which are fed to the needles (5) and oriented by means of compressed air supplied by compressed-air nozzles. In order to provide such knitted fabrics on their inside with thread loops (12) consisting of individual fibres previously inserted, provision is made for orienting the fibres, after their insertion into the ground fabric (11), upwards via a first suction-air nozzle (4) and for feeding them to the needle ends over a guide (7) by means of a second suction-air nozzle (6), so as to form, with their cooperation, thread loops which consist of the individual fibres and which are located on the inner face of the fabric. The subject of the invention is therefore the process for producing these thread loops and the constructive means and the products produced by the process. <IMAGE>

Title: Process for producing a precast wall panel from lightweight concrete
Inventor: LECHNER BERND
IPC: B28B1/087
Filed: 1988-03-19
Abstract: There is a process in which a mixture of aggregate, binder and water is compacted while vibrating in a mould having a smooth mould base and is made to set to form a structure with internal porosity of the aggregate particles. In this case, it is desirable for the precast wall panel to be provided already in the mould with a wall surface smooth enough to be brushed, avoiding a subsequent trowling operation. This is achieved by the mixture being vibrated from below in the mould until there is produced on the smooth mould base a continuous layer of binder 23 with few pores on its bearing surface. After setting, the said layer forms a wall surface 24 which, without trowelling, is smooth with few pores and suitable for brushing. The vibrating from below causes the formation of the layer of binder with few pores in its bearing surface, this layer forming the brushably smooth wall surface. <IMAGE>

Title: Multi-cylinder piston pump
Inventor: IHRING ANTON
IPC: F04B1/04
Filed: 1988-08-16
Abstract: In a multi-cylinder piston pump, pistons (5) deliver, via pressure channels (15), into a common annular space (14). A valve plate (20), which contains specially designed indentations (23) and outflow orifices (25, 26, 27), is inserted into the annular space (14). An O-ring (22) held in a groove (21) presses a sealing washer (18) against a seat (24) of the valve plate (20). The indentations (23) and outflow orifices (25, 26, 27) can be drilled and embossed into the valve plate (20) in a simple way. Owing to the special shape of the outflow orifices (25, 26, 27), large outflow cross-sections and thus small valve lifts are obtained. As a result, pressure peaks and noises can be reduced. <IMAGE>

Title: Packaging container, in particular bottle
Inventor: RINKE CHRISTIAN
IPC: B65D23/12
Filed: 1988-10-27
Abstract: There is a constant requirement to package gifts in an attractive manner. In many cases the gifts are presented together with a full bottle (10). In this case, it has proved to be difficult to package the gift together with the bottle (10). Attempts to accommodate the gift in the filling space (18) of the bottle (10) filled with the beverage have also proved to be unsuccessful. The invention intends to provide a suitable packaging container, in particular a bottle (10), which allows simple packaging of an additional article without difficulty. The invention now proposes a packaging container, namely a bottle (10), which has at least one further, separate additional filling space (19) which is accessible from the outside. An article (or even a plurality of articles) to be presented can thus be packaged in the bottle (10), unaffected by the beverage contained in the filling space (18), specifically even after the bottle (10) has been filled with a beverage or without having to open the filling space (18) for the beverage. The invention is particularly suitable for presenting items of jewellery and money in a bottle (10) filled with champagne or a different beverage. <IMAGE>

IPC: B22D11/126
Filed: 1988-11-11
Abstract: An arrangement for the longitudinal dividing of slabs with several longitudinal-dividing lines. The slab length already cut in each case is detected via displacement-measuring systems and is compared with the remaining length still to be cut. A slab-feed carriage which can be activated always advances automatically up to the longitudinal-dividing line with the shortest remaining length and holds the new slab to be longitudinally divided in a waiting position. The longitudinally divided slabs or slab bars are removed by means of a slab-discharge carriage which positions itself in front of the same longitudinal-dividing line as the slab-feed carriage. Slab feed and slab discharge can always be effected simultaneously.

Title: Valve arrangement for a hydraulic system
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F15B11/16
Filed: 1988-12-30
Abstract: The invention relates to a valve arrangement for a hydraulic system in which a plurality of consumers are attached to a variable-delivery pump via in each case a measuring choke and a pressure balance. The pump control valve for setting the delivery quantity is connected via a signal line and in each case a spring-loaded stop valve to the consumer-side feed between the measuring choke and the pressure balance. The stop valve opens in the direction of the signal line during a pressure difference which is greater than the pressure difference required to open the pressure balance, so that the energy for actuating the pump control valve has to be applied by the pump and not by the consumer. The simple means of the spring-loaded stop valve therefore prevents a consumer from briefly stalling when it is started under load.

Inventor: VOELKNER WOLFGANG ING GRAD
IPC: B64D15/20
Filed: 1989-03-11
Abstract: Method for using measurement technology to detect an attack of ice which is located on exposed components of a flying vehicle, in particular an aircraft or helicopter, and which after it has been detected is removed by a thermal, for example electrical, deicing system. Energy-saving control is rendered possible by providing that heating elements are heated, and that the intensity of the thermal radiation generated by the heated surfaces is measured and compared with the radiation intensity which this surface would have were it free from ice. The supply of heating energy for the deicing system is regulated for a deicing operation as a function of the difference in the radiation intensities of the ice-free and iced states of the surface.
