Title: Motor vehicle headlamp with HV discharge bulb
Inventor: YAMAMOTO NOBORU
IPC: F21S8/10
Filed: 1997-08-28
Abstract: The HF lamp (1) is driven by a power supply with a frequency of several tens of Mhz. The discharge lamp produces a bright light which is reflected by a shaped reflector (7) behind the lamp.

Patent DE-19740554-A1 (DE)
Title: Combined hydrostatic and hydro-mechanical transmission for motor vehicle
Inventor: NAGATOMO KUNIYASU
IPC: F16H39/02
Filed: 1997-09-15
Abstract: The combined hydrostatic gear box (HSG) has several modes of operation and incorporates a differential hydraulic motor powered by a variable hydraulic pump. The differential pressure hydraulic motor has a swash plate (53) linked to a power output shaft (16) and cylinder block, linked in turn to a drive power input shaft.  The gear box further incorporates a brake which operates against the cylinder block (22) torque as required, and a clutch which disengages the cylinder block torque motion as required. If the brake is operated while the clutch is disengaged and receives fluid from the variable oil pressure pump, the differential pressure hydraulic motor then operates in HSG-mode. When the brake is released, the clutch is engaged to receive fluid from the variable hydraulic pump and the differential pressure hydraulic motor then functions in an hydro-mechanic gear mode.

Title: Mixing of liquid carbon di:oxide into poly:ol of polyurethane foam mixture
Inventor: SULZBACH HANS-MICHAEL DIPL ING
IPC: B29C44/34
Filed: 1997-09-24
Abstract: In a process for adding a metered amount of carbon dioxide into a polyol flow at a pressure just above the equilibrium pressure for the dissolved gas, one or more metered polyol flows (P1, P2 and P3) are combined and a branch pipe (22) feeds part of the flow to a pump (23) which raises the polyol pressure to a suitable level for the addition of the carbon dioxide at a static mixer (24) and maintaining it in a fluid state in the polyol. The part flow then recombines with the main polyol flow and pressure is reduced to a level just above that at which the carbon dioxide vaporises and the polyol flow is mixed with an isocyanate (2). Also claimed are: (i) the production of polyurethane foam using liquid carbon dioxide as the blowing agent; and (ii) the apparatus for the above process, comprising a polyol branch pipe (22) with a pressure increasing pump (23), a carbon dioxide injecting system (25), a static mixer (24) and a by-pass pipe (21) for the main polyol flow, and a pressure holding valve (6) after the recombining point for the branch and main flows, which is followed by a foam component mixer (1) with a pressure relaxation valve (4) at the outlet.

Patent DE-19811039-A1 (DE)
Inventor: YIN LIN
IPC: H04N7/50
Filed: 1998-03-13
Abstract: A method of coding an audio signal comprises receiving an audio signal x to be coded and transforming the received signal from the time to the frequency domain. A quantised audio signal x is generated from the transformed audio signal x together with a set of long-term prediction coefficients A which can be used to predict a current time frame of the received audio signal directly from one or more previous time frames of the quantised audio signal x. A predicted audio signal x is generated using the prediction coefficients A. The predicted audio signal x is then transformed from the time to the frequency domain and the resulting frequency domain signal compared with that of the received audio signal x to generate an error signal E(k) for each of a plurality of frequency sub-bands. The error signals E(k) are then quantised to generate a set of quantised error signals E(k) which are combined with the prediction coefficients A to generate a coded audio signal.

IPC: H02K21/20
Filed: 1998-08-20
Abstract: A DC induction machine has the stator (2) provided with open outer slots and an iron casing (1).
