Title: Process for the production of refrigerant distributors, especially for evaporators of an air-conditioning system of a motor vehice
Inventor: BURK ROLAND
IPC: F25B39/02
Filed: 1993-06-09
Abstract: Known refrigerant distributors, in which the main duct becomes increasingly narrower and the secondary ducts project into the main duct with mouth cross-sections directed opposite to the direction of flow, in such a way that as uniform a liquid/steam mixture distribution as possible takes place, are complicated to produce. It is proposed to produce the basic body for the injection device from an extruded metal profile which is subsequently cut into discs which are, in each case, closed at the sides and, if necessary, also on the top side by means of soldered-on metal plates. Use for refrigerant distributors for the air-conditioning systems of motor vehicles. <IMAGE>

Title: Method and arrangement for extracting a colour subcarrier-frequency signal
Inventor: FISCHER DIETER
IPC: H04N9/45
Filed: 1993-09-02
Abstract: A method and an arrangement for extracting a colour subcarrier-frequency signal from a digital PAL colour television signal is proposed. In this arrangement, a sampling signal (4fsc) accompanying the PAL colour television signal is frequency-divided by means of a divide-by-4 circuit (19). To fix the phase angle of the divide-by-4 circuit (19) unambiguously, a reset signal is generated which is extracted from in each case two samples adjacent to the horizontal and vertical frequency of the colour synchronisation signal contained in the digital PAL colour television signal. <IMAGE>

Title: Sports shoe sole with elastic layer of evenly hard material between tread sole and upper - has perforations right through elastic layer in heel and foot arch parts
Inventor: ROMO REIMA JUHANI DIPL ING
IPC: A43B13/18
Filed: 1993-10-01
Abstract: The perforations (16) penetrating the elastic layer (13) of the sole are most numerous in back part of the heel, in relation to the surface area of the elastic layer in order to increase the elasticity and shock absorption of the tread sole. The perforated part's area decreases from the back of the heel forwards to the arch of the foot part. The unperforated part correspondingly increases in those parts (17, 18) of the sole's structure (12) giving support to the foot. ADVANTAGE - The sports shoe especially is suitable for various types of foot by having the sole's elastic layer made of homogeneously hard material, perforated at the heel and foot arch.

Title: Self-insulating latent heat store useful for large-scale heating
IPC: F24D3/14
Filed: 1993-12-21
Abstract: Latent store, which develops self-insulating properties through special structural pts. and a special supply pipe, has crystallised paraffin structures formed around a liq., thermally charged internal paraffin core and hence overall a highly insulating latent store with high storage capacity, which can take up large amts. of heat and heat to high temp. without commercially-available insulation. The contents are ecologically acceptable and the store can be installed without extra protective equipment, e.g. for drinking water. The paraffins used are solid at normal outdoor temps. and hence cannot mix with e.g. soil or ground water. Besides the main function, the store has different sec. functions, e.g. natural or controlled evolution of heat to the surroundings, and can be of any shape.

Patent DE-4445813-A1 (DE)
Inventor: OESTERLE HELMUT
IPC: B25B23/14
Filed: 1994-12-21
Abstract: An adapter (12) for an axial percussion machine, such as an impact drilling machine (13), has two telescopic coupling members (14, 15) spring-loaded in the axial direction so as to slide inside each other and co-operate in the direction of rotation. One coupling member (14) is connected to the driven axis (17) of the impact drilling machine (13) and the other coupling member (15) receives a driving tool (18) for driving in a screw (1) into a workpiece (9). An adjustable depth stop (16) is arranged on the fixed part of the impact drilling machine (13). When driving in a screw, this adapter allows the drilling process to be assisted by an axial percussion force applied by the impact drilling machine (13). The depth stop (16) substantially reduces the axial compression force at the end of the drilling process, so that the axial force required for cutting the thread can be applied by a helical spring (23). This small axial force no longer causes the application of an axial percussion force by the impact drilling machine (13).

Patent WO-8903983-A1 (WO)
Inventor: BROSI THOMAS
IPC: G01M15/00
Filed: 1988-10-26
Abstract: Les procédés traditionnels pour déterminer la pression de combustion d'un moteur à combustion interne sont très onéreux et les capteurs utilisés doivent répondre à des exigences sévères. Le procédé décrit diffère des procédés précités en ce que l'on calcule la pression de combustion en déterminant la pression de compression pk(alpha) et en mesurant la pression de la chambre d'explosion p(alpha) au moyen de simples capteurs. On obtient la pression de combustion p*(alpha) en soustrayant de la pression de la chambre d'explosion la valeur de la pression de compression. On obtient de préférence la variation de la pression de compression en mesurant la pression de la chambre d'explosion pendant la compression jusqu'au point mort ou dans la phase d'explosion et en stockant les valeurs dans une mémoire. On obtient les valeurs de compression apparaissant après atteinte du point mort haut, par symétrie sur un axe passant par le point mort haut, ce qui donne une courbe symétrique de pression de compression. On peut ainsi calculer très facilement la pression de combustion.
