Title: Variable volume high pressure hydraulic pump - has separate throttled circuit for cooling and lubricating oil supplied to main pump
Inventor: FRICKE HANS-JUERGEN DR ING
IPC: F04B49/00
Filed: 1977-01-29
Abstract: A variable volume high pressure hydraulic pump (11) is driven by a motor (10) to deliver oil to a hydraulic power circuit (12). Another motor (13) drives a feed pump (14) which supplies the main pump (11) through an inlet pipe (17).

Title: Electromagnetic aperture control with stable location - uses array of fixed permanent magnets around control coils on setting ring
Inventor: PROSS WILHELM
IPC: G03B9/10
Filed: 1977-06-27
Abstract: The aperture setting ring has one or more fingers (2a) supporting two small coils (20, 21).

Title: Roasting mixt. of limestone and solid fuel in shaft furnace - where part of the fuel is replaced by natural gas mixed with air fed into bottom of shaft
Inventor: BOTSCH GUNTHER DIPL ING
IPC: C04B2/12
Filed: 1978-03-21
Abstract: A mixt. of limestone and solid fuel is fed into the top end of the shaft furnace, whereas air mixed with fuel gas is fed up the shaft from the outlet for the roasted lime. When the mixt. of gas and air is fed into the furnace, its concn. of fuel gas is below that at which ignition occurs; and the ratio solid fuel:fuel gas is kept very high, i.e. using a very small amt. of fuel gas so that no separate fuel gas combustion zone is present in the shaft. The conversion of the fuel, i.e. solid fuel plus fuel gas in the combustion zone of the shaft corresp. at all times to the degree of roasting of the limestone required; and the position of the combustion zone is pref. altered by adjusting the fuel gas: O2 ratio. A gaseous fuel can be used together with solid fuel in roasting lime, so the amt. of solid fuel required is reduced: and an excess amt. of fuel is avoided so roasting costs are reduced and a uniform prod. obtd.

Title: Electronic fuel injection control for vehicle engine - incorporates computer to adjust mixture strength to avoid mechanical resonance
Inventor: KOBAYASHI AKIO
IPC: E03B3/03
Filed: 1978-05-31
Abstract: An electronic circuit (12) controls the quantity of fuel injected (1a) into the engine (1) in accordance with a signal it receives from a digital computer (11).
