Title: Vehicle wheel suspension for stabilised cornering - with pendant subframe pivoted above centre of gravity to adjust tilt to centrifugal force
Inventor: LOEFFLER WALTER
IPC: B60G3/00
Filed: 1975-12-01
Abstract: The suspension has a subframe with a cross member (2) to link the wheels. The cross member is linked to the chassis by elastic, damped plates (10, 20) and is suspended from a pivot (8) set above the centre of gravity of the vehicle. As the vehicle corners the body is set to tilt into the corner, and with suitable choice of springs and subframe the amount of tilt can be set to equal the centrifugal force. This provides an upright setting during cornering. The cross member is linked to the pivot point by rigid struts (5, 6) to form a triangle with the cross member. The tilt axis is in line with the vehicle and the struts can be profiled to fit the contours of the body shell. A stable setting for the pivot axis is in the roof line, for maximum effect.

Title: Automatic rerouting system for radio telephone calls - chooses strongest signal connection path via main or secondary transceiver
Inventor: BRAAK DIRK JOHAN DIPL ING
IPC: H04W36/18
Filed: 1976-02-11
Abstract: The automatic re-routing system, for radio telephone calls (linked to switched land-line network), is especially intended for hilly areas and towns and has--apart from the main radio transceivers--secondary radio transceivers. An unengaged radio receiver in each secondary transceiver scans all voice channels in its radio area and remains connected to that receive channel having a signal voltage greater than a given limit for as long as that signal exceeds the limit. A comparator at the main transceiver compares the signal strength from the receive channel at the main transceiver with the strength of the same channel at the secondary transceiver. The call is routed over the stronger path. The whole process is dynamic.

Title: Proportional action flow regulating valve - maintains constant flow ratio between hard and soft water flows by poppet reacting to soft water supply pressure
Inventor: UPHOFF HANS-GERHARD
IPC: G05D11/00
Filed: 1976-04-30
Abstract: A proportional action control valve provides a constant volumetric flow rate ratio between hard and soft water. As the rate of flow of soft water diminishes due to a tank emptying the hard water flow is proportionally reduced. Soft water is supplied (A) over a cone shaped poppet (3) to outlet (B). A valve stem (4) couples the poppet to another cone shaped poppet (6) regulating the flow of hard water from another inlet (C) to outlet (O). A piston (5) is provided to ensure that the pressure of the hard water does not produce an axial force on the valve stem. Both the poppet (6) and the piston (5) are threaded onto the valve stem which may be turned (8) to provide adjustment. The main poppet (3) reacts to the soft water pressure to move the stem providing proportional flow rates.

Title: Metering sensitive solid into reactor - by fluidisation, esp. for polymerisation catalyst
Inventor: DORN INGO H DIPL ING DR
IPC: B01J8/00
Filed: 1976-05-31
Abstract: Fluidisable solids, which must not be subjected to temp., press. and/or impact stress, are metered into a reactor by fluidising the solids and transferring it from a vortex bed into the reactor by means of a propellant gas stream, opt. with addn. of minor amts. of fluidisation aids. The claimed sensitive solid is a polymerisation catalyst azobisisobutyronitrile and other aliphatic azo cpds., and peroxides, are specifically claimed. Even small amts. of solids, e.g. 100 g/hr., can be accurately and uniformly fed to a reactor. In a polymerisation process, constant amts. of catalyst can be metered into the reactor over long periods of time; blockage of the appts. is avoided. As well as polymerisation catalysts, other additives, e.g. pigments or filter aids, can be metered by this method. An inert gas, e.g. N2 or He, is pref. as fluidisation medium. Azobisisobutyronitrile is crystalline and easily forms agglomerates; addn. of a fluidisation aid, e.g. SiO2 gel, avoids this trouble.

Title: Tuning of electric end circuits in electromechanical filters - uses additional inductance connected to circuit which is then tuned to auxiliary frequency
Inventor: ALBSMEIER HANS ING GRAD
IPC: H03H3/007
Filed: 1976-09-17
Abstract: The circuits are tuned to a nominal frequency f1 within the filter pass band. Each circuit is mistuned to a frequency f3 outside the pass band by addition of a reactance of a known value. An auxiliary frequency f 2 for the circuit tuning with the additional reactance is derived from the additional reactance and a fixed circuit reactance, so that when the additional reactance is removed, the circuit is tuned to the nominal frequency f1. The additional reactance is an inductance, and the fixed circuit reactance is a variable inductance.
