Title: Hydrostatic support for moving component - has pressurised hydraulic bleed from piston forming oil film between components
Inventor: MIESCH HANS DIPL ING
IPC: F16C13/00
Filed: 1978-09-26
Abstract: The hydrostatic support consists of a piston(1) sliding in a housing(4) which has a support head(5), divided into chambers(61, 62) open at the top. The underside of the piston(1) and the inside of the housing(4) encloses a normally-pressurised space(10) which is connected to the chambers(61, 62) by holes(9) bored through the piston. The hydraulic pressure thus supplied to the chambers creates a pressure film between the top of the support head and the surface(2) of the moving component(3).

Abstract: A heat exchanger for two fluids comprises a closed, cylindrical vessel in which tubes for the first fluid pass through the vessel, while the second fluid flows through the spaced around the tubes inside the vessel. All feed and returns pass through the top closure (2) of the vessel. The first fluid tubes lead from the top closure (2) near the outer perimeter down inside the vessel near to the outer wall, turn around in a loop (7,8) and pass back up again into the central region; both ends of the tubes connect to headers (9,9', 10) passing out through the top closure. The outer and inner branches of the looped tubes are separated by an open-bottomed cylindrical shell (3), the top end of which is connected to a concentric second tube (11) around the inner header (10). The second fluid passes through this tube (11) to flow down through the top closure into the vessel. Further concentric tubes (12,12', 13) surround the outer headers (9,9') for the first fluid and also the second tube (11) for the second fluid; these last tubes (12,12', 13) communicate with the annular space outside the open-bottom shell (3) and inside the vessel wall; those concentric tubes (12,12') of this last group which surround the inlet headers for the first fluid constitute the outlet headers for the second fluid. Preferably, the last tube (13) of this last group is equipped with a cooling coil (18).

Patent DE-2918533-A1 (DE)
Inventor: MARLEY JOHN
IPC: G10L11/02
Filed: 1979-05-08
Abstract: A system and method for speech recognition provides a means of printing phonemes in response to received speech signals utilizing inexpensive components. The speech signals are inputted into an amplifier which provides negative feedback to normalize the amplitude of the speech signals. The normalized speech signals are delta modulated at a first sampling rate to produce a corresponding first sequence of digital pulses. The negative feedback signal of the amplifier is delta modulated at a second sampling rate to produce a second sequence of digital pulses corresponding to amplitude information of the speech signals. The speech signals are filtered and utilized to produce a digital pulse corresponding to high frequency components of the speech signals having magnitudes in excess of a threshold voltage. A microprocessor contains an algorithm for detecting major slope transitions of the analog speech signals in response to the first sequence of digital signals by detecting information corresponding to presence and absence of predetermined numbers of successive slope reversals in the delta modulator producing the first sequence of digital pulses. The algorithm computes cues from the high frequency digital pulse and the second sequence of pulses. The algorithm computes a plurality of speech waveform characteristic ratios of time intervals between various slope transitions and compares the speech waveform characteristic ratios with a plurality of stored phoneme ratios representing a set of phonemes to detect matching therebetween. The order of comparing is determined on the basis of the cues and a configuration of a phoneme decision tree contained in the algorithm. When a matching occurs, a signal corresponding to the matched phoneme is produced and utilized to cause the phoneme to be printed. In one embodiment of the invention, the speech signals are produced by the earphone of a standard telephone headset.

Title: 5-Ethyl-deoxy:uridine use in combination with fluoro:uracil - in treating cancer and in immunosuppressive therapy
Inventor: GAURI KAILASH KUMAR DR
IPC: C07H19/06
Filed: 1979-05-22
Abstract: New use of 5-ethyl-deoxyuridine (I) is in combatting malignant diseases. (I) considerably increases the cytostatic activity of fluorouracil. Under the influence of kinase, (I) is converted into 5-ethyl-2'-deoxyuridine-5'-monophosphate (II) which is a very effective donor of deoxyribose monophosphate under the influence of nucleoside phosphorylase. The deoxyribose monophosphate is transferred to fluorouracil to form the active species 5-fluoro-2'-deoyuridine 5'-monophosphate. 5-Ethyluracil formed in this transfer reaction is excreted unchanged in the urine, and does not give rise to toxic side effects.

Title: Emergency telephone installation for traffic road system - with by=pass circuit maintaining connection to emergency control centre in event of power failure
Inventor: JUERGENSMEIER ROLF ING GRAD
IPC: H04M11/04
Filed: 1979-09-14
Abstract: Each telephone (FSE) of a motorway emergency telephone installation is associated with a line (OVST) to the local automatic exchange. By operating a pushbutton (AT) a caller initiates an automatic number selection process which connects him with the emergency control centre for the motorway. A switching unit (ASS) at the individual telephone controls the number selection and connection of the control centre operator with the caller. A supervisory circuit (SPU) monitors the power supply which is drawn from the exchange. In the event of a failure an already connected caller is automatically reconnected by the supervisory circuit to bypass the switching unit and thus avoid interruption. At the same time the loss of supply is signalled to the control centre for rectification.
