Abstract: In a separable lightweight armchair comprising a backpiece (6), two sidepieces (2) and a seatpiece (4), the sidepieces (2) are separably edge-assembled with the backpiece (6), in that they from a slantingly backward directed position are inserted on firm coupling parts (26) on the backpiece (6), in that the coupling parts (26) are inserted in the clearance between two parallel framewires (16, 18) on the sidepiece (2), and hereafter rotated forwards to a locking mesh with the coupling parts. The sidepieces (2) are locked in their forwardly directed normal position by means of a traverse piece (12) at the front.Through this invention a very simple and fully stable assembling is achieved without any use of separate coupling parts. The same coupling technique is usable, generally, between panel elements in otherfurniture or similar structures.

Abstract: In the production of medium carbon steel wire rod, upon leaving the hot rolling mill, the rod is cooled in two phases. The first phase is operative as the rod moves at end-of-rolling speed along a cooling line disposed between the finishing block and feed rollers disposed at the entry of a head for placing the rod in overlapping turns on a conveyor, the cooling line being continuous-i.e. being devoid of air cooling breaks between consecutive intensive cooling sections, the length and capacity of the cooling line being such that the surface temperature of the rod at the end of the first phase is between, on the one hand, the start-of-martensitic-transformation temperature for the particular steel concerned and, on the other hand, the latter temperature plus 200 DEG  C. The second cooling phase is operative upon the rod once it has been placed in overlapping non-concentric turns on the conveyor, the time which elapses between the end of the first phase and the start of the second phase being less than the time needed for the percentage of transformed austenite to exceed 5%. Austenite transformation is at least 95% at the departure from the second phase.

Abstract: The invention relates to a charge-coupled device, in which the reset transistor of the output is clocked -with a positive threshold voltage -by a maximum voltage equal to the supply voltage V<sub>DD</sub>. The drain (14) of the reset transistor is adjusted by means of an auxiliary transistor (T,) controlled by a current source (T2) and having the same threshold voltage, whose gate (21) is applied to V<sub>DD</sub> and whose source (22) is connected to the drain (14) of the reset transistor. Due to the fact that the maximum gate voltage is equal to V DD, additional voltage sources, such as charge pumps, for generating voltages higher than V<sub>DD</sub> are superfluous.

Abstract: A video signal is modified so that a television receiver will still provide a normal color picture from the modified video signal while a videotape recording of the modified video signal produces generally unacceptable pictures. This invention relies on the fact that typical videocassette recorder automatic gain control systems cannot distinguish between the normal sync pulses (including equalizing or broad pulses) of a conventional video signal and added pseudo-sync pulses. Pseudo-sync pulses are defined here as any other pulses which extend down to a normal sync tip level and which have a duration of at least 0.5 microseconds. A plurality of such pseudo-sync pulses is added to the conventional video signal during the vertical blanking interval, and each of such pseudo-sync pulses is followed by a positive pulse of suitable amplitude and duration. As a result, the automatic gain control system in a videotape recorder will make a false measurement of video level which causes an improper recording of the video signal. The result is unacceptable picture quality during playback. This approach utilizes positive-going pulses which occur at a time not ordinarily used for black-level restoration in typical television receivers, and therefore does not give rise to black level depression in such typical television sets.

Abstract: A dilatation catheter or a balloon catheter assembly for use in angioplasty and the like includes a shaft (4) made of an elastomeric tube reinforced with longitudinally inelastic filaments. In the distal balloon portion (I) of the unpressurized shaft, the filaments lie at an angle ( beta ) which is less than a predetermined critical angle ( alpha ). In the adjacent movable portion (II) of the shaft, the filaments lie at an angle ( sigma ) which is greater than the critical angle ( alpha ). When the shaft (4) is pressurized, the balloon portion (I) expands in diameter and the movable portion (II) contracts in diameter until the filaments in each portion lie at the critical angle ( alpha ). At the same time, the length of the movable portion (II) increases so as to offset the reduction in length of the balloon portion (I).

Abstract: The invention is directed to a food processing apparatus (2) having a lid (22) adapted to be placed on a vessel (10), with a cover member (26) of semi-circular cross section and having a passage (24) opening into the vessel (10) being provided on the lid. The cover member (26) is provided with a vertically extending rectangular receiving opening (32) for receiving a semi-cylindrical receptacle (34) adapted to swivel through 180 DEG  between a loading position and a discharge position. The receptacle (34) is adapted to receive whole fruits (45) without the operator contacting the shredding or cutting tools (12, 13), because the receiving opening (32) is closed in the loading position of the receptacle (34). Following loading of the fruits (45) into the receptacle (34), the latter is swivelled through 180 DEG , enabling the fruits to be discharged through the passage (24) into the vessel (10) where a cutter blade (12) is used, while in the use of a shredding or cutting disc (13) the fruits will come to lie on the disc for being processed following which they will drop into the lower part of the vessel (10). With the receptacle (34) in the discharge position, the processing tool (12) is not accessible from the outside either because in this position, too, the receptacle (34) maintains the receiving opening (32) closed.

Abstract: A valve member (E) for a shut-off valve has a stem tip seal (F) and is adapted for selective movement axially towards and away from an associated valve seat (76). A generally cylindrical sleeve (80) is carried by the valve member (E) and has an end defining an outer annular seal surface (91) adapted for cooperative sealing engagement with the seat (76). Mounted centrally within the sleeve (80) for limited axial movement is a rigid cylindrical body (88) that defines an inner annular seal surface (90) adapted for engagement with the seat (76) at a location radially inwardly of the outer annular seal surface. Formed between the sleeve (80) and the rigid body (88) is an annular chamber (96) which opens axially inwardly from a narrow slot (94) located between the inner annular seal surface (90) and the outer annular seal surface (91). A mass of resilient packing material (97) substantially fills the chamber (96) and extends axially outwardly of the slot (94) to define a medial annular seal surface (103). Means are associated with the rigid body (88) for generating pressure on the packing material (97) when the body is forced axially towards the valve member (E). In addition, the inner annular seal surface (90) is configured to engage the seat (76) prior to engagement by either the medial annular seal surface (103) or the outer annular seal surface (91).
