Patent DE-3741600-A1 (DE)
Title: Table knife
IPC: B32B15/01
Filed: 1987-12-08
Abstract: A known table knife consists of a blade made of a rust-resistant, hardenable and weldable, chromium-alloyed steel and a handle made of nickel chromium steel which consists of two handle shells with formed-on enlargement which tapers to blade thickness. The handle shells are welded together to form a handle and the blade is butt-welded to the tapering region of the enlargement. As a result of the different colouring of the materials, however, the transition between blade and enlargement is visible. As nickel chromium steel is not hardenable, the tapering region maintains its deformability so that the knife can bend at this point. In the knife according to the invention, however, the handle also consists of a rust-resistant hardenable chromium or chromium molybdenum steel and is hardened together with the blade.
Patent DE-3744179-A1 (DE)
Title: Mounting and filling device for a hydropneumatic piston accumulator
Inventor: PEIFFER JOACHIM DIPL ING
IPC: F17C5/06
Filed: 1987-12-24
Abstract: The invention relates to a mounting and filling device for a hydropneumatic piston accumulator for introducing a pressurised gas into the gas space without the need for a special gas-filling orifice and for mounting the piston within the device which is under gas pressure. Conventionally, the piston is driven into the housing by means of a plunger driven by external forces, a compression of the hitherto existing initial volume already under pressure taking place. At the same time, gaskets on the piston are loaded on one side and therefore exposed to the risk of destruction if they have to slide in this state, for example over a spring-ring groove. According to the invention, such damage is avoided by ensuring that the same pressure rise always prevails in the mounting space as in the gas space and therefore a balanced-pressure behaviour, also present in subsequent operation, is achieved. This is obtained by means of a plunger which is thicker than the piston and a volume of the mounting space which is in the same ratio to the volume of the gas space as the annular surface resulting from the difference in diameter between the plunger and piston to the piston surface. Moreover, a backflow of gas to the pressure source is prevented.

Filed: 1988-09-22
Abstract: Apparatus for controlling the pressure-balancing operation in a pressure change gas adsorption plant used particularly for the adsorptive separation of gas mixtures, in particular in the obtaining of oxygen or nitrogen from air, consists of gas-pressure actuated pressure-balancing valves (9, 10, 11) and control valves (21, 22, 23) which are in communication via a control gas line (27) with the pressure- balancing valves. The pressure-balancing valves (9, 10, 11) are each constructed as double diaphragm valves. During the adsorption process in one of the adsorbers (1, 2, 3), the intermediate space between the two diaphragms in all the pressure-balancing valves is subjected to control gas, causing these valves to be closed while in contrast, during the pressure-balancing, the pressure-balancing valves (9, 10, 11) are not subjected to control gas. In this case, the pressure- balancing valve which is not participating in the pressure- balancing operation is loaded by product gas (30, 31, 32) from the adsorber which is giving up the pressure during the pressure-balancing thus causing it to remain closed. <IMAGE>

Abstract: The equipment according to the invention consists of a boom (4) which is fastened to a slewing device (2) in the front part of the frame of a chassis (1) of a loader for picking up excavated material from the floor and is equipped with a shovel (16), servomotors (5, 11, 14 and 15) and hydraulic lines (19). The boom (4) is shaped in such a way that, in the position where the base of the shovel (16) is located in the plane of contact of the machine with the lower part, it occupies the space over a predominant length LN with a maximum height which is equal to the height HC of the shovel (16). The ratio of this length LN to the length L - measured from the front edge of the shovel up to the articulation point of the boom (4), the joint (3) arranged in the slewing device (2) - is equal to or greater than 0.7. Here, the relationship between the height H of the articulation point of the boom (4) at the slewing device (2) and the height HC of the shovel (16), namely that the height H is greater than the height HC, is maintained. The boom (4) has a box structure and its end provided with the shovel is increased in width and has the shape of a fork, the arms of which have an outer width which at most is equal to the width of the shovel (16). The side and base walls (17, 18) of the boom (4) form an angle in the shape of an "L". The hydraulic lines (19) fixed with clamps (20) are arranged in this angle. <IMAGE>

Patent DE-3907247-A1 (DE)
Title: Communications equipment
Inventor: RANNER GEORG ING GRAD
IPC: H04M1/72511
Filed: 1989-03-07
Abstract: In cordless telephones, a radio channel is seized with the aid of a code which is agreed between a base unit and a mobile part and which the unit requesting a radio link transmits on a free radio channel. Due to signal crosstalk or similar effects, the code is sometimes also identified by the receiving unit on an adjacent channel and this adjacent channel is incorrectly seized in the return direction. To prevent an incorrect channel seizure of this type, the invention proposes the provision of a plurality of synchronisation patterns, the number of synchronisation patterns being lower than the number of channels. Synchronisation patterns which differ from one another are assigned to adjacent channels during the synchronisation signal selection. The invention is used, for example, in cordless telephones.
