Title: Treating piston slide paths - using laser beam performing motion similar to honing motion
Inventor: NAGEL WOLF DIPL ING
IPC: B23K26/362
Filed: 1992-05-27
Abstract: The method concerns treatment of piston slide paths made, in particular, of cast iron. The surface (3) is finished by honing and is then subjected to treatment by means of a laser beam focussed onto it. The laser beam is applied to individual surface elements over brief time periods, so that only the scale cover of graphite segments is opened, without removal of material from the surface. Pref. a laser with a short wavelength is led over the surface with a motion similar to the honing motion. The beam is either point or line focussed onto the surface. The beam from a laser located outside the tool is brought to the tool via a light guide. The laser is modulated (in particular, switched on and off) to produce a required surface texture of the piston slide path. USE/ADVANTAGE - In the motor industry. Its use results in improved wear resistance, as well as in reduced oil and fuel consumption. Simpler (and hence cheaper) piston rings can be used.

Title: Depolymerisation of polycaprolactam - by melt depolymerisation in presence of alkaline catalyst, with addn. of di- or poly-carboxylic acid anhydride to form imide co-catalyst
Inventor: MUELLER WOLFGANG DIPL CHEM
IPC: C07D201/12
Filed: 1992-08-31
Abstract: A process for the rapid alkaline depolymerisation of polycaprolactam (I) comprises depolymerisation in the melt in the presence of conventional catalysts (e.g. alkali metals, hydroxides and/or carbonates) (II), with addn. of di- and/or poly-carboxylic acid anhydrides (III), opt. contg. additional functional gps., so as to form imide co-catalysts and reduce the melt viscosity. Pref. (III) are, e.g. cyclic anhydrides of succinic, maleic, phthalic, trimellitic, pyromellitic or benzophenone- tetracarboxylic acid. USE/ADVANTAGE - The process enables the rapid depolymerisation of (I) (esp. scrap polyamide) at relatively low temp. to give relatively pure caprolactam without producing any toxic residues with disposal problems. The added anhydride (e.g. trimellitic anhydride) reacts with (I) to form, e.g. 5-carboxyphthalimido-n- hexanoic acid and its homologues, which act as imide co-catalysts to displace the equilibrium towards depolymerisation. The process also reduces the viscosity of the melt, thus facilitating dispersion of catalyst (II) and removal of caprolactam from the melt.

Title: Pneumatic switch valve for air intake of exhaust pipe of IC engine - has seal dependent upon size of membrane of positioning component
Inventor: PUSCH DIETER
IPC: F01N3/30
Filed: 1992-09-03

The positioning component of the switch valve is activated by the suction pressure of the engine and, on shutting off, closes under a spring force. The positioning component (7) is activated in the closing phases of the exhaust gas pressure. Pressure change-over occurs via an electromagnet valve (11) with three connections. Downstream from the valve area (4) in the direction of the switch valve blocking flap valves are arranged. The electromagnet valve (11) is controlled from an electronic control appts. dependent upon the operating parameters of the internal combustion engine. ADVANTAGE - Valve is sealed even at high exhaust gas pressure.
Patent DE-4234139-A1 (DE)
Inventor: STICKEL OSKAR
IPC: B60T1/08
Filed: 1992-10-09
Abstract: The invention pertains to a control device of a hydrostatic transmission with a hydraulic pump (1), an adjustable hydraulic motor (2) and a brake valve (5) in two working lines (15, 16) connected to the hydraulic motor and the hydraulic pump, which brake valve closes one of the working lines when the transmission is in override, with a regulating device (8) working from a control pressure taken from the working lines between hydraulic motor and brake valve and used to adjust the displacement volume of the hydraulic motor, and with a control valve (9) for regulating the control pressure admission depending on a control signal. While maximum braking torque is maintained, the braking action of the hydrostatic transmission is improved in that the control signal is proportionate to the speed of the hydraulic motor and, as this speed increases, controls the pressure control admission, via the control value (9), toward minimal displacement volume of the hydraulic motor (2), and in that when a predetermined pressure difference appears in the working line segments (15, 19; 16, 22 and 15, 20) between hydraulic pump (1) and brake valve (5) as well as brake valve (5) and hydraulic motor (2), with a higher pressure in the latter working line segments (15, 20; 16, 23), an override valve (11) overrides the control valve (9) by controlling the control pressure admission toward maximum displacement volume of the hydraulic motor.

The leading edge of the foil is always secured between the article and following layer without fixing on the article.
