Patent DE-3711688-A1 (DE)
Title: Packaging apparatus for foodstuffs
Inventor: HAERLE FRITZ
IPC: B65B25/06
Filed: 1987-04-07
Abstract: The packaging apparatus for foodstuffs, especially for the packaging of sliced sausage and cheese products, works very economically. Along with a high material throughput and the lowest possible rejection rate, the product or its packaging can be changed while the apparatus as a whole is running. The product is sliced directly by the cutting-open apparatus onto one or more product carriers adapted to the packaging units. The individual product carriers not connected to one another are fed to a weighing station by means of a product transport system and, if the weight is incorrect, are re-metered in a product-transport system loop. In the event of an overload of an apparatus part or a change-over of an apparatus part to another product, the product carriers are stored in one or more buffer loops and worked off later.   In a transfer station, the sausage product is brought directly out of the product carrier into the packaging in the correct form. The product carriers are thereafter guided automatically through an integrated cleaning station. The transport system is designed as an internally cooled tunnel, thereby affording a high degree of hygiene and better working conditions.
Patent DE-3713799-A1 (DE)
Title: Hydrostatic drive system
Inventor: METZNER FRANK DR ING
IPC: F16H61/46
Filed: 1987-04-24
Abstract: A hydrostatic drive system consists of an adjustable primary unit and an adjustable secondary unit which are connected to one another via a conduit with an applied pressure. The volume flow of the primary unit is controlled speed-dependently as a function of the applied pressure and the volume flow of the secondary unit. In order to avoid an excessive fall in the applied pressure, the power of the secondary unit is limited. Provided for this purpose is a circuit in which the volume flows of the primary and secondary unit are compared. Power limitation takes effect when the volume flow of the secondary unit exceeds the volume flow of the primary unit.

Title: High-pressure cleaning apparatus
Inventor: SCHULZE WERNER ING GRAD
IPC: B05B12/08
Filed: 1987-07-23
Abstract: In a high-pressure cleaning apparatus with a high-pressure pump whose suction side is connected to a liquid reservoir, with a closable pressure line and with a flow monitor in the pressure line, to achieve an automatic control of the high-pressure pump, it is proposed that the flow monitor switches off the high-pressure pump when the flow falls below a minimum value and switches on the high-pressure pump when the flow exceeds a flow threshold value lying above the flow minimum value.

Patent DE-3743247-A1 (DE)
Inventor: KREBS JOCHEN
IPC: D21B1/34
Filed: 1987-12-19
Abstract: To achieve the best possible uniform pulping in a pulper in a shorter time with favourable energy input, it is proposed to optimise geometrical measurements of the base rotor (12) arranged at the base of the pulper vessel (2), and of a transport screw (6) directed towards the rotor and the arrangement of the screw. The lower end (14) of the transport helical screw (6) extends to the immediate vicinity of the highest point of the base rotor (12). The distance between the end of the transport screw (6) and the highest point of the base rotor (12) is smaller than 1/10 of the diameter of the base rotor (12). The diameter of the imagined circular surface of the lowest screw flight is about one third to one quarter of the diameter of the base rotor (12). The generatrix of the helix is inclined downwards to the axis of the transport screw (6) in the transport direction. Flat deflector plates are arranged on the inner circumference of the vessel (2) to direct the flow in the direction of the middle of the vessel (2). In this way, formation of a vortex in the transport flow in the vessel is prevented and a favourable toroidal transport flow is created. <IMAGE>

Title: Self-propelled lift truck
IPC: B66F7/04
Filed: 1987-12-19
Abstract: The invention relates to a self-propelled lift truck for pallets, containers or the like, having a main platform and a bridge platform which can be lifted and lowered independently of one another, the lifting movement of the main platform being effected by fixed hydraulic piston/cylinder arrangements (1) which act on chain arrangements (9) which in each case act on the main frame (2) of the truck and on the main platform (11) and are designed as operating chain and catch chain. The object of the present invention is to create a chain arrangement which is subject to minimum wear and in addition has a low overall depth. This object is achieved by each piston/cylinder arrangement having at least one operating chain (12, 14) and a catch chain (13) which are arranged next to one another. <IMAGE>

Title: Apparatus for the treatment of a textile fabric web
Inventor: KURSCHATKE WOLFGANG
IPC: D06B3/20
Filed: 1988-01-11
Abstract: The apparatus serves for the treatment of a textile fabric web (10) with a treatment liquor (2) and comprises hoses (20, 30) which are arranged opposite one another on both sides of the fabric web (10) and which are filled with a fluid pressure medium and can be inflated and relieved of pressure respectively as a result of a pulsating application of pressure to the fluid pressure medium. Pressure surges are thereby generated in the liquor and result in a better attack of the liquor on the fabric web running past between the hoses (20, 30). A plurality of pairs of hoses (20, 30) can be arranged in succession along the path of the fabric web (10). Instead of the hoses (20, 30), other chambers which can be filled with fluid pressure medium and which have flexible walls can also be used. <IMAGE>

IPC: H04B1/69
Filed: 1988-05-07
Abstract: A radar system produces monocyclic pulses by switching 228 a DC power supply 65 to a wideband antenna 204, 206 in accordance with the output of a signal generator 212. The transmitted pulses are very broadband and thus will not interfere with any narrowband receiver. The receiver mixes 230 received signals with the output of a template generator 232 so that only signals received a certain time, set by delays 235, 236, after transmission are received. These are then integrated 250, digitized 256, and integrated again 262 to allow rejection of noise and returns from a different transmitter operating at different times. An analagous communication system (Figs 1-4), using pulse position modulation to encode an audio signal, is also described. <IMAGE>

Title: Purpose-made concrete block as masonry block for a dry construction method
Inventor: ROTH REINER DIPL ING
IPC: E04B2/22
Filed: 1988-07-13
Abstract: The invention relates to a purpose-made concrete block as masonry block for a dry construction method, having any outline or a rectangular outline as parallelepipedal block, the casing surface of which has vertical grooves in some sections. The core of the invention consists in the fact that the purpose-made concrete block has one or more cavities over the entire height of the block and, matching these cavities, one or more elevations project over the surface of the purpose-made concrete block and/or that, seen in outline, in the case of an imaginary rectangle, each of the two long sides is replaced by two concave portions and the two narrow sides are replaced by a convex portion in each case, one of the two convex portions being, in turn, replaced centrally, but not over the entire length of the portion, by a concave portion. The basic advantage consists in the fact that, by using the purpose-made concrete block, an angled and curved dry masonry wall can be erected, which is interconnected horizontally and vertically. <IMAGE>
