Title: Combined cut=off and bench type circular saw - has pivoted saw assembly mounted above table on thin plate which acts as knife
Inventor: SCHNIZLER ALBRECHT
IPC: B27B5/16
Filed: 1989-07-15
Abstract: The sawing slide (3) moves on a slideway at the top of a thin plate (2) fastened to the top of the table (1). An arm (4) carries the circular saw blade and motor drive assembly (6,7,9), which pivots (5) on the slide (3). The saw blade (8) and plate (2), whose thickness is slightly less that that of the saw blade, are aligned in the same vertical plane. In the table along the line of cut is a narrow slot to accept the saw blade. For cutting-off a stop (8) is fixed to the table, by means of the hand grip (9) the blade is lowered into the work until it enters the table slot and the cut is completed. For bench sawing the stop (8) is removed and a parallel guide may be fixed to a table extension. The arm is dropped until the blade enters the table slot and locked in position with the pivoted strut (10). The plate (2) now acts as a riving knife, ensuring a safe clean cut as the work is pushed past the saw. USE/ADVANTAGE - Rapid change-over of sawing machine. Free access for work. Safe to use.

In order to provide temporally unlimited possibilities for recording and reproducing with a non-limited number of recording and reproducing channels, to access any point of the recording instantaneously, to carry out risk-free overdubbing and editing and to select any desired duration of fading in and out, a bidirectional interface circuit with inputs and outputs is connected, through a system bus carrying groups of parallel data, to one or more storage modules connected in parallel, a main control circuit is connected to the system bus and to the storage module(s) and is controllable through an operating unit, and each storage module has at least one digital store with an interchangeable storage medium and at least one digital buffer memory. The audio signals to be stored are thus kept in the buffer memory for processing or during interchange of the storage medium.

Title: Fluidised bed for thermal regeneration of used foundry sand - has synthetic resin binder removed by heat and uses regenerated sand heat to warm used sand entering the bed
Inventor: OBERLEITNER RUPERT DIPL ING
IPC: B22C5/08
Filed: 1990-04-14
Abstract: Thermal regeneration of used foundary sand bound by synthetic resin involves combustion of the resin in a fluidised bed. The waste gases loaded with injurious materials are burnt in a combustion chamber (3). The waste gases are conducted over heat exchangers (4) through the fluidised bed such that a thermal transfer is acheived between the burnt waste gases and the layers of fluidised bed sand. In this way the sand is heated to the required temp. for regeneration. The sand is continuously fed through an inlet (1) into the chamber. Before the heated and regenerated sand leaves the unit, it is fed past plate-like esp. ribbed heat exchanger surfaces. This flow of sand runs in the opposite direction to that of the sand which is to be heated. ADVANTAGE - The meeting of heated regenerated sand with that to be heated, reduces the energy input and hence enables the former heat exchanger (4) to be of smaller dimensions. Furthermore, the cooling unit for the regenerated sand can be similarly reduced in size.

Abstract: PCT No. PCT/DE91/00431 Sec. 371 Date Jan. 31, 1992 Sec. 102(e) Date Jan. 31, 1992 PCT Filed May 24, 1991 PCT Pub. No. WO91/19086 PCT Pub. Date Dec. 12, 1991.The invention relates to an intake system for an internal-combustion engine charged in one or two stages. The intake system is to be used with as few changes as possible in both a one-stage as well as a two-stage supercharging. The exhaust gas turbochargers, the charge air coolers and the air collecting housings as well as the interconnect pipes between these system parts and the pipes to the inlet ducts of the cylinder heads are used in the same arrangement in both a one-stage and a two-stage supercharging. The arrangement of the charge air cooler used in the one-stage supercharging, is the same as the high-pressure charge air cooler of the two-stage supercharging. The arrangement of the exhaust gas turbochargers in the one-stage supercharging, is the same as that of the high-pressure exhaust gas turbochargers in the two-stage supercharging. Additional advantageous are achieved by the arrangement of the charge air coolers on the air collecting housing and exhaust gas turbochargers on a narrow side of the air collecting housing.

Title: Determining clearance rate of lipoprotein and apoprotein in e.g. serum - by injecting biotinylated low density lipoprotein(s), used to evaluate risk factors for sudden death associated with atherosclerosis
Inventor: HOFF EDUARD
IPC: G01N33/92
Filed: 1990-06-08
Abstract: Process for measuring the clearance rate of low density lipoproteins in serum or plasma utilises biotinylated low density lipoproteins. The biotin is pref. linked covalently to the lipoprotein via a spacer, esp. a medium chain hydrocarbon. The biotinylated apoprotein is pref. integrated into a liposome.  A process for measuring permanent plasma proteins, esp.  lipoproteins and apoproteins of type apoAI, apoAII, apoAIV, apoE, is also claimed. USE/ADVANTAGE - Used to determine risk factors for sudden death associated with atherosclerosis. The lipoproteins which carry cholesterol are bound by surface cell receptors, and the clearance rate varies with the number of saturation degree of the receptors, so a low clearance rate is associated with a high risk. Previous methods of measuring clearance rates involved radioactive iodine and could only be carried out in specialised laboratories. The new method dispenses with the need for trichloroacetic acid pptn., which is necessary when radiolabelled proteins are used. The method can also be used to study proteins in apoprotein complexes, etc..

Inventor: SOELLNER GERHARDT
IPC: F16C7/02
Filed: 1990-06-16
Abstract: The connecting element according to the invention, having eyes for holding joints, bearings or attachment elements, consists of a tube or of a profile (1) like a tube. The tube ends are flattened so that the tube walls run towards one another from the undeformed region in a pointed manner and merge into flat tongues (4) at the ends. The eyes (2) are formed into these tongues (4) by flow-boring. This produces eyes (2) having solid walls (3) which project out of the tongues (4) like beads. In order to increase the torsional stiffness, a reinforcing bead (6) can be formed in the region of the deformed tube ends. In addition, the gap (5) between the tube walls which rest on one another can be filled, for example, with a bonding agent or a solder material. <IMAGE>

Title: Improving control of three=phase pulse inverter - changing over inverter switches according to current-tolerance band regulating method
Inventor: SALAMA SAMIR DR
IPC: H02P27/10
Filed: 1990-07-06
Abstract: The regulating deviations of the phase currents are determined by phase comparators, and upon reaching or overstepping specified tolerance bands for the phase currents, a set of controls is brought into effect. The switches are changed over so that respectively, upon exceeding a positive tolerance limit by a current regulating deviation of a phase, this phase is changed over to plus potential of the intermediate circuit voltage (on "1") and, upon exceeding the negative tolerance limit, to minus potential of the intermediate circuit voltage (on "0"). In the operating position "free-running" of the switching positions (000 and 111), upon reaching or overstepping a tolerance limit of the tolerance band of a determined phase, the two other phases are changed over, if one determined phase lies already at the correct potential of the intermediate circuit voltage for a correction so that a correcting change-over is not possible there. USE/ADVANTAGE - Preventing overstepping of current peaks during free running phases. Due to quick reaction, current regulating deviations are kept small.
