Title: Automatic focuser for reflex camera - has partially reflective reflex mirror and completely reflective auxiliary mirror directing light via beam splitter to two receivers
Inventor: SCHAEFER KLAUS DIETER DIPL ING
IPC: G02B7/34
Filed: 1976-08-02
Abstract: Opto-electrical automatic or semi-automatic focusser for reflex camera comprises two photoreceivers (10, 11) with strips or grid elements which are connected in pairs to a comparator (14) which produces an extreme signal when the objective 2) is in focus. Behind a partially reflective reflex mirror (3) is a completely reflective auxiliary mirror (2) which deflects rays to the bottom of the camera and behind which is an auxiliary lens which projects an image of the subject image formed in an intermediate image plane, onto the photoreceivers. In the aperture diaphragm of the auxiliary lens is a striplike double wedge which splits the imaging rays of the auxiliary lens into two partial beams for opposite aperture zones of the objective, which are transmitted to the photoreceivers separately.

Title: Integrated circuit with several IGFET - has thin insulating layer provided on all gates and higher threshold voltages obtained by ion implantation
Inventor: ARNDT JUERGEN DIPL ING DR
IPC: H01L21/8234

Patent DE-2720988-A1 (DE)
Inventor: MEWALD FRANZ ING
IPC: E06B9/84
Filed: 1977-05-10
Abstract: In order, in the case of excessive lowering speed of the room closure member, for instance a roller door armour, to prevent the continuation of the lowering movement, a pawl (6) is provided, which engages in a locking manner in a ratchet (9) connected to the winding roller of the roller door armour. The pawl (6) is to this end supported by a pivotable support (4), on the other end of which a planet wheel (2) is arranged. The planet wheel (2) meshes on the one hand with a sun wheel (3) driven by the ratchet (9) and on the other hand with an external wheel (5) rotating at constant speed by means of a gear (1). In the case of a predetermined operating speed of the winding shaft, the axis of the planet wheel (2) and thus the support remain stationary. If the speed increases beyond this value, the planet wheel (2) drifts, with pivoting of the support (4), as a result of which the pawl (6) is released. In this connection, a switch (13) for switching off the drive is actuated at the same time. The device acts already in slight cases of the speed being exceeded and therefore does not have to absorb any excessive forces. <IMAGE>

Title: Cooling water jacket for IC engine - is divided into upper and lower sections of different cross sections
Inventor: KOERNER WOLF-DIETER DIPL ING
IPC: F02F1/16
Filed: 1977-06-16
Abstract: A cooling water jacket (6) is formed between the cylinder liner (7) and the inside of the cylinder block (1). Water enters this jacket at the bottom (2) and part of it leaves at the bottom (3) diametrically opposite the inlet. The remaining part flows up the jacket and leaves through an outlet (9) at the top from which it enters the cylinder head (10). A plate (5) divides the jacket into upper and lower sections (4a, 4b) and has an opening (8) through which the water flows from the lower to the upper section. The plate is positioned so that the cross section for flow of water is considerably smaller in the upper than in the lower section. This gives stable flow with good heat transfer in the upper section.

Title: Flushing water economiser for water closets - has ball and cock arrangement to limit outlet of release arm
Inventor: SEMLER OSKAR
IPC: E03D1/14
Filed: 1977-12-16
Abstract: The water economiser varies the volume of flushing water coming from the cistern. A trip device raises the release arm and thus the ball from the valve seat s that flushing water can leave the cistern, as soon as the operating handle is lifted or pressed. A float is automatically connected with the ball and its weight acts on the ball when it is off the valve seat and the water falls to a level which is higher than the level at which the ball returns to the seat. A locking device prevents the float from sinking too low so that the coupling device is operated. The float is also prevented from sinking too low when the handle is deflected in a first direction.

Title: Testing of motor vehicle IC engines - by accelerating engine from slow to top speed idle running and allowing it to decelerate and stop while monitoring speed
Inventor: ZUERNER HANS-JUERGEN DIPL ING
IPC: G01M15/00
Filed: 1978-03-22
Abstract: The usual test equipment for measurement of various parameters are combined in one test unit and connected to an IC engine. The engine is then operated in accurately specified, reproducible conditions. The engine is driven against the mass moments of inertia of its components without any additional load from slow idel running freely accelerating to top speed idle running, and then allowed to decelerate without fuel supply until it stops. Then the test unit processes the measured data as function of time and the results are compared with known rated values to determine if there are any functional faults in the engine.
