Title: Toggle system for closing injection mould - has hydraulic cylinder and requires only single preset pressure limit, using combination of servo-valve and main control valve
Inventor: HUMMEL ERHARD
IPC: B29C45/68
Filed: 1990-11-08
Abstract: In toggle systems for closing hydraulically injection moulds, where the closure unit has a central drive to regulate the height of the tool and hence the closing force, the hydraulic cylinder to move the toggle has an adjustable pressure limit which is provided by a servovalve and maincontrol valve combination. In the process the oil flow through the servovalve is measured during the mould closure, while the closing pressure is building up the max. oil flow is compared with a two set levels these are between a min. (which is above zero) and a max. below the set level when the main control valve operates, the difference between these is set by the min. level of the closing force. If the lower of the levels is not attained the height of the mould tool is reduced, if it exceeds the higher level that height is increased. ADVANTAGE - As the closing pressure builds up only one single pressure needs to be set beforehand. The process shortens the injection moulding cycles.

Patent DE-4106131-A1 (DE)
Inventor: ROMBERG LOTHAR ING GRAD
IPC: H02K1/28
Filed: 1991-02-27
Abstract: 2.1. The rotors of small electric motors are as a rule produced for customer requirements since it is rare for there to be a small motor which can be supplied to a second or to several customers in the same configuration. The construction of the rotor shafts according to the invention allows the rotors to be produced in large batch sizes independently of a customer-specific construction of the shafts. 
<??>2.2. The rotor shaft is constructed in three parts, the shaft centrepiece (12) holding the rotor laminar stack (11) and having free ends (12', 12'') which overhang the ends (13, 14) of the rotor on both sides. The one end (12') of the shaft centrepiece (12) is used in this case as a holder for the separately produced shaft stump (15) on the drive end, and the shaft stump (16) on the non-drive end, which is likewise produced separately, is mounted on the other end (12'') of the shaft centrepiece (12).

Filed: 1991-09-21
Abstract: The travelling cleaning assembly, which moves along the line of bobbin winding stations, has a common underpressure channel for dust along the line of the machine for the air inlets at the winding stations and the air inlets of the wall cleaner. The underpressure channel is at the head of the textile machine secured by tube connections leading to the air inlets at the winders.

Inventor: HARTMANN ALBRECHT DR
IPC: F02B33/34
Filed: 1991-11-22
Abstract: The invention concerns a vehicle with air-cooled friction brakes (8) and an internal-combustion engine supercharged by a mechanically powered supercharger (2). By means of an air-supply valve (6) fitted in the charge-air feed line (4, 4a, 4b), the air flow from the supercharger (2), which is also powered when the vehicle is being braked, is supplied to the brakes (8) as cooling air.

Further, carboxyl gps. on the polymer are wholly or partly neutralised with sodium, potassium, ammonium, or organic amine ions. USE/ADVANTAGE - The medicaments which can take the form of tablets, granulates or capsules, can be used for the admin. of e.g. antirheumatics, contraceptives, and cardiovascular drugs, esp. by the peroral or vaginal route. The medicaments have better release, stability, and/or bioavailability characteristics than known bioadhesive formulations such as those described in e.g. US4615697, US4795436, DE3800256 and DD-282551. In partic. they adhere to tissue, esp. mucous membranes, over a long period and swell rapidly to produce a non-toxic bioadhesive mucilage which covers a large surface and which promotes absorption of the drug.
