Title: Annular hydraulic implement with pressure chamber - with coaxial cylindrical recesses provided in bores passing through chamber
Inventor: LOECKMANN HANS WERNER
IPC: F16J10/02
Filed: 1976-03-06
Abstract: Annular hydraulic implement with an annular hydraulic pressure chamber which essentially is formed from two annular parts which can move relative to each other where bores (1/11, 12-11/8) pass through the two parts and the hydraulic pressure chamber which is filled with hydraulic medium. Specifically, coaxial cylindrical recesses are provided in each bore and in each of these is a cylindrical sealing casing (1/13), whose inner smooth bore corresponds to the bore in the two construction parts. The sealing casing has a peripheral groove with a ring seal so fitted in each end that a ring space (111/16) remains in the groove. This space is connected with the hydraulic pressure chamber and, considering the deflection path of the sealing casing in the axial direction, it has a greater expansion than the hydraulic pressure chamber in its maximum expansion which is caused by the generation of higher pressure.

Title: Intermittent drive for strip mill feed roller - has rotation sensing device to reduce load on driving mechanism
Inventor: SCHLEICHER HERMANN
IPC: B21D43/08
Filed: 1976-05-19
Abstract: The feed roller (6) of a strip rolling mill is driven with intermittent motion from the cylinder (1). The cylinder (1) imparts a reciprocating motion to the toothed rack (2) which drives the pinion (3). The drive is then transmitted through the free wheel (5) and torque converter (7) to the feed roller (6). To prevent overshoot of the drive due to the inertia of the roller (6) a rotation sensing device (8) is fitted to the torque converter (7) which brings the drive to rest as soon as the end of the toothed rack (2) reaches the stop (9). This prevents excessive loading of the free-wheel and of the rack and pinion drive which enables the dimensions of these parts to be reduced.

Title: Automatic door operator with safety trip - uses centrifugally operated switch to latch motor supply if door is obstructed
Inventor: STEWART JOHN ALEXANDER
IPC: E05F15/40
Filed: 1977-07-30
Abstract: The electric motor for a door operating gear has a shaft (1) on which are mounted two identical plastic members (2, 3). One of these (2) is rigidly attached to the shaft, whilst the other is free to slide axially. A series of radial recesses (4) are formed in the plastic members to accommodate steel balls (5), and they are held together by a spring (8). Initial energising of the motor brings it up to speed, causing centrifugal effects to move the balls outwards so that the spring closes the members (2, 3). This in turn operates a switch (9) causing the motor to continue to operate, but at a very reduced voltage. Should an obstruction be encountered, the speed will drop as the motor tends to stall, causing the switch to trip and de-energise the motor.

Patent DE-2738773-A1 (DE)
Inventor: MORI SHIGEO
IPC: H04R1/22
Filed: 1977-08-27
Abstract: An electroacoustic transducer particularly for small small-sized portable equipment such as a wristwatch comprises a first vibrating plate which is vibrated by means of an electromagnet and a second vibrating plate which is coupled with the first vibrating plate by an airtight space which acts as an air spring. The first and second vibrating plates have different natural resonant frequencies so that the vibration system comprising the two vibrating plates and the air spring coupling them with one another forms a vibration system having two resonant frequencies. A resonant air chamber superposed on the second vibrating plate has a sound radiating port and has a resonant frequency between the two resonant frequencies of the vibration system comprising the first and second vibrating plates and coupling air spring. The electroacoustic transducer thus responds to a considerable range of frequencies.

Title: Galvanic cell with metal chalcogenide positive electrode - with micro-contact between electrode and terminal to stabilise voltage
Inventor: SAUER HANS
IPC: H01M6/12
Filed: 1977-10-15
Abstract: Galvanic cells comprise a negative electrode consisting of a light metal or Zn and a positive electrode consisting of a chalcogenide (oxide or sulphide) of a multivalent metal which discharges in >=2 stages. The positive electrode is insulated from the positive terminal by a non-conductive plastics layer. The improvement lies in the fact that the positive electrode is connected to the positive terminal exclusively via a conductive contact whose contact area with the metal chalcogenide is so small that at a current of 15 mu A, the chalcogenide giving the lowest discharge voltage is reduced to the metal (or to phase most deficient in chalcogenide) at a faster rate than the metal (or phase most deficient in chalcogenide) is oxidised to the high-valence metal chalconide with which it is in electrolytically conductive contact. The cells are esp. suitable for use in electronic wrist watches. The cell voltage is rapidly stabilished at the value corresp. to the discharge potential of the most stable chalcogenide, while the whole capacity of the electrode is still utilised.
