Title: Hybrid electrical vehicle propulsion system - has constant output generator and I.C. engine
Inventor: WALDORF LINDSEY EARL
IPC: B60L11/00
Filed: 1974-02-09
Abstract: The hybrid system has an electric motor as a propulsion unit driven solely by a storage battery for a period when its tension is above a first preset value and by a constant output generator turned by an internal combustion engine when the battery tension falls below a pre-set value. The generator performance is sufficient to both propel the vehicle and recharge the battery. The difference between the fixed output performance of the generator and the variable input performance of the traction motor is used to recharge the batteries. The fact that the engine is used only at constant speed and performance permits a favourable layout to minimise toxic exhaust emission.

Title: Photographic process for production of printing block - uses photolithographic layers which are built up to required thickness
Inventor: FISHBURN CHARLES EDWARD
IPC: B41C3/00
Filed: 1974-03-21
Abstract: The selected scene is prepared as a positive and placed over a photolithographic emulsion and exposed. The covered parts of the scene are then washed away by the developing fluid. a second photolithographic emulsion is applied and bonded to the first, and the exposure/development process repeated. When sufficient relief is obtained with the photolithographic layers they are placed in intimate contact with a soft layer, to transfer the imprint. The layer is then hardened and the emulsions removed, leaving the printing block. The process dispenses with the costly zinc plate etching process, and can be performed on automatic alignment equipment.

Title: Immobilized protein preparations - in which proteins are bound to polymeric carriers via hydrazine residues
Inventor: WILCHEK MEIR PROF
IPC: C12N11/00
Filed: 1975-07-07
Abstract: Water-insoluble protein preparations consists of a polymeric water-insoluble carrier (pref. agarose polymer, polyacrylamide, polyethylene/maleic anhydride polymer, starch aldehyde polymer, a 'Sephadex' (RTM) type polymer, cellulose, a substd. cellulose, polyamide or glass) linked with a biologically active protein via a linking group formed by anchoring hydrazide moieties to the polymer skeleton, reacting with a suitable dialdehyde (pref. glutaraldehyde), and coupling with the protein via functional groups which are not essential for its biological activity. Immobilization of proteins such as enzymes (e.g. trypsin, chymotrypsin, ribonuclease or alpha-amylase), antibodies or serum albumin to give water-insoluble protein derivs. which can be used in column form. The linkage between polymer and protein is relatively long, so that the biological activity of the insolubilized protein is relatively high. Relatively high protein/carrier ratios can be used.

Machine is further provided with a second electric motor for driving the fibre openers and with a third motor for driving the induced draught fan. A control device is arranged such that on switching on for tripping the cups it produces a pulse for reducing the speed of the first motor to a slow spinning starting speed of the devices and a pulse for opening of the valves for ejector nozzles, a further pulse for releasing the couplings and a pulse for switching off the yarn monitors being produced when the starting speed has been attained; control device then produces a succession of pulses to release the coupling between the motor and the devices and actuation of brakes for these devices, to actuate the yarn cutting devices following stopping of devices and to close the valves, to de-energise the motor; the device producing a succession of pulses for re-starting the spinning by energising the second and third electric motors and tripping couplings and yarn monitors on reaching the slow speed; the preceding pulses being followed by a pulse to switch the motor for running at its high speed until the slow speed is attained; a pulse for opening the valves and pulse for connection of the devices to the reversibly driven member through its coupling, the driving connection being interrupted when the yarns have reached the spinning groove of the cups, whereupon a pulse is produced to connect the devices to the couplings and close the valve; a pulse for energising the yarn monitors and finally a pulse for bringing the motor to its high speed. All spinning stations are re-started simultaneously with yarn ends being fed to spinning cups, following tripping of machine during which a yarn break occurs at each station.

Title: Level control of blast furnaces using temperature - by cascading the set point for crude gas temp. from the level
Inventor: UHDE HORST
IPC: C21B7/24
Filed: 1976-01-28
Abstract: The actual value of the crude gas temp. is measured continuously and balanced against the set point. If the actual value exceeds the set point, then the furnace can be set for charging. The temp. set point is continuously adjusted w.r.t. the difference between the actual level and a set normal level (below the max.). When the actual level is below the normal level, the set point is reduced, while if it exceeds the normal level, it is raised. The set point adjustment only occurs if the measured difference between the crude gas temp. set pt. and actual value do not exceed a prescribed amt. It also only occurs if the difference between set point and actual value of level exceed a certain value. System is used on blast furnace systems so that more precise control of the batch charging operation can be more closely controlled, giving uniform operation and consistant quality of pig iron.
