Patent EP-0010605-A1 (EP)
Inventor: CARLSON JOHN ARTHUR
IPC: A01D34/76
Filed: 1979-09-19
Abstract: Apparatus for loading a collet (456) with respect to a rotatable drive hub (430) of a magnetic disk drive apparatus to grip a magnetic disk between the collet and drive hub, includes a leaf spring (460) supported at opposite ends with respect to a machine frame (422) and carrying the collet (456) at an intermediate place between the ends. One end of the spring (460) is pivotally mounted on a boss (462) on the frame and the other end has a sliding connection in a slot (468) in a web (466) of the frame. A manually rotatable shaft (470) has an offset portion (469) carrying a roller (472) to apply force on the leaf spring between its pivotal mounting and the collet so as to move the collet to engage the disk between the collet and drive hub against the resilience of the leaf spring. The leaf spring is relatively wide in its portion (461) between its pivotal mounting and the collet and is relatively narrow between the collet and its other end so that the narrow portion (463) of the spring bends the wide portion (461) of the spring as the collet is moved towards the hub. The collet thereby grips the disk uniformly with respect to the hub and the longitudinal centre of the collet remains nearly coincident with the longitudinal centre of the hub as the collet completes its disk engaging movement with respect to the hub to avoid side thrust on the disk.

Title: An automatic trap for catching cockroach
Inventor: CHEN HUANG SHWU JEN
IPC: A01M23/14
Filed: 1979-12-28
Abstract: An automatic trap for catching cockroach mainly includes an automatic control mechanism. As cockroaches enter into the trap, they will inevitably touch a switch (28) of said automatic control mechanism (10) to drive a slipping plate (24) forward and further to automatically sweep these cockroaches into a confinement cell (36). After that, the slipping plate (24) will be also automatically back to its original position, restoring the control function of the automatic control mechanism, which is the particularly advantageous feature of the invention.

IPC: B65H9/06
Filed: 1980-04-25
Abstract: in an apparatus for aligning pliable sheet material, such as paper, feed rollers (12) feed the material between guide members (16, 17) so that its leading edge is forced against at least a portion of a stop surface (24) and then, if necessary, the material buckles to allow its leading edge to align with the stop surface (24). The stop surface (24) is formed on an alignment lever (25) which is held fast on a shaft (26) which can pivot in bearings (27). However, the alignment lever (25) is latched by a latch bar (38) so that the stop surface (24) lies in the path of the sheet material. A sensing member (32) senses when the leading edge of the material is aligned with the stop surface (24) and releases the latch bar allowing the lever (25) to pivot, due to sheet material being forced against the stop surface (24) by the feed rollers (12), so that the material enters the nip between transport rollers (22). The sensing member (32) is disposed at one end of a lever (34) which is held fast on a shaft (35)-pivotally mounted in bearings (36), the latch bar (38) being also held fast on shaft (35). Alternatively, the latch bar (38) may be released from the lever (25) in response to photoelectric sensing of the fact that the leading edge of the material is aligned with the stop surface (24).

Abstract: In a buckle for a safety belt, a pivotable latch (13-17) is arranged, relative to the push-in tongue (4), in such a way that the ejector force (11), or the belt force loading the tongue, urges the latch out of engagement. Provided to prevent this, in the closing position, is a securing device which, in one position (FIG. 1), holds the latch firmly in the latching position and, in another position (FIG. 2), releases the latch for opening. According to the invention, this securing device is designed as a pivoting lever (21), in order, on the one hand, to increase the degree of safety and, on the other hand, to lessen the opening force, at a moderate production outlay. The pivoting lever is mounted in such a way that it cannot leave the securing position even under shock stress from any direction whatever.

Abstract: In an oil-filled electric power cable installation, the oil is pressurized using oil tanks connected to stop joints in the usual way, and an oil-purifying unit is connected between stop joint and tank. The oil-purifying unit comprises a column or bed of a molecular sieve or other active purifying agent with particle sizes, and interstice sizes, big enough to limit the pressure drop across the unit to 20 kN/m2 at the most. This eliminates the need to provide bypass passages controlled by valves as the oil can flow both ways through the column.

Abstract: Geometry of a recording material for microfilming of technical drawings permitting the simplification of the construction, regulation and utilisation of this material. The dimensions of the rectangular exposure table for the documents to be microfilmed fall within the series A of ratio  2ROOT 2. The plane of the optical axis of the recording apparatus - perpendicular to this table - contains a diagonal of the exposure table. This arrangement permits the easy framing of the documents to be microfilmed, the determination without ambiguity of the rate of reduction to be applied in the course of the microfilming, the systematic inclusion in the object field of a recording counter and a rule giving the scale. The invention may be employed to construct recording apparatuses having a space requirement and a weight which permit microfilming on the archiving premises. <IMAGE>

Abstract: To accumulate solar energy, a solution of a hydroxide of alkalin metals is dissociated, by means of solar heat, into water and into the water-depleted component. A hydroxide of alkaline-earth metals is first transformed in a container (10), by means of solar heat, into an oxide which absorbs the water vapour formed under vacuum conditions in the container (30, 300) on top of a solution of the alkaline metal hydroxide. When heat is required, the product obtained, depleted of water and vacuum-contained in the container (30, 300, 46), is brought in contact with the water vapour which forms on top of stored water in another container (20, 310). The product absorbs the water vapour which is continuously replaced by fresh vapour. The container removes heat from the environment, the ground or outdoor air. The product absorbs water and is heated. The heat released may be used for heating.
