Abstract: Torsion damping isolator assemblies (19 or 100 or 200) are disposed for damping torsionals in a vehicle driveline. The assemblies include spiral springs (62 or 202,204) and a vane damper assembly (22 or 206) disposed in parallel and immersed in automatic transmission fluid of a torque converter housing (24). Damper assemblies (22 or 206) include first and second relatively rotatable housing members (66,68 or 208,210). Housing members (66 or 208) are connected to radially inner ends (62b or 202b,204b) of the springs, and members (68 or 210) are connected to radially outer ends (62a or 202a,204a) of the springs. The housing members define chambers which vary inversely in volume in response to flexing of the spring assemblies by driveline torsionals. The chambers communication with the fluid in the torque converter housing via restricted passages (86,88 or 220f,220g). As the chambers vary in volume, energy from the torsionals is converted to fluid pressure in the chambers decreasing in volume. Assemblies (19 and 100) include lugs (77a) drivingly connecting the second member (68) to the torque housing. The lugs define valving members (77c,77d) which close or partially close the passages associated with the chamber decreasing in volume. Assembly 200 includes improved mounting (228,230) of the spring outer ends (202a,204a) and improved mounting (238) of the spring inner ends (202b,204b). Damper assembly (206) includes independent pistons (220) circumferentially held in position by drive lugs (226) which also function as valving members in a manner analogous to lugs (77a).

Abstract: In a process for manufacturing a thin film transistor, a first polysilicon layer (11) is formed on a substrate, a dielectric layer (12) is formed on part of the first layer, and a second polysilicon layer (13) is formed on, and over the same area as, the dielectric layer. A layer (14) of refractory metal, such as titanium, is then deposited on the second polysilicon layer and on the exposed regions of the first polysilicon layer. A reaction is then caused, for example, by annealing, between the metal layer and the polysilicon layer so that silicide regions are formed to provide source, gate and drain electrodes (15,16,17). Unreacted areas of the metal layer are then removed by selective etching.

Abstract: In a circuit arrangement with a switching amplifier (10), particularly for hearing aids, for limiting a pulse-duration-modulated signal (S3) which is formed from a low-frequency signal (S1) and a higher-frequency triangular signal (S2), the output signal which can be taken from the switching amplifier is to be limited with only little distortion and without reducing the gain. For this purpose, the pulse-duration-modulated signal (S3) is supplied to a circuit (5; 14; 18) which changes in the pulse-duration modulated signal (S3) the duration (D1, D2, D4) of individual pulses, the duration (D1, D2, D4) of which is greater than or/and less than a maximum or respectively minimum pulse duration (D3; D5), which can be predetermined by the circuit (5; 14; 18), and in which the pulse-duration-modulated signal (S5; S6) changed by the circuit (5; 14; 18) can be supplied as input signal to the switching amplifier (10). <IMAGE>

Abstract: 1. Process for modifying a completely inorganically synthesised zeolite of the pentasil type. 2.1 Pentasil zeolites having an Si/Alskeleton ratio of </= 50 are synthesised as a rule in the presence of structure-forming additives, so-called templates. This synthesis variant has a number of serious drawbacks, which preclude preparation on a large-industrial scale, which at the same time is environmentally friendly. 2.2 The object is to produce, on the basis of pentasil zeolites, which have been prepared without templates, and by the simplest possible modification steps and without introducing further elements, catalyst components which are highly active, highly selective and which have good long term stability. The process is characterised in that the water vapour treatment for the purpose of partial removal of aluminium from the zeolite is carried out at a temperature between 300 and 500 DEG C, and after the partial extraction of the extra-skeleton aluminium a short term hydrothermal treatment of the zeolite is carried out at a temperature of at least 600 DEG C for as long as is required to achieve an Si/Alskeleton ratio of at least 130. 2.3 The process is used preferably for modifying a completely inorganically synthesised zeolite of the pentasil type.

IPC: B60T8/18

Abstract: 2.1. Known braking systems for lorries with a service brake and a retarder generally use the brake-pressure-actuated pneumatic pressure switch to switch in the retarder. The disadvantage is the superimposition of the braking effect of the retarder on that of the actual service brake. This results in unwanted progressions in the braking effect, particularly in the range of low decelerations and when the vehicle is empty or only partially loaded. 2.2. The invention proposes a braking system of the type described under Point 1, in which at least the upper braking stages (R5, R6) of a retarder put into operation can, if required, be switched off again, this being done as a function of the deflection of the control lever (4) of an ALB controller (3) of a lorry fitted with leaf springs. A satisfactory braking effect can thereby be achieved with simple means, even in the range of low accelerations when the vehicle is unloaded or partially loaded. <IMAGE>
