Abstract: Abstract of disclosure.          A ski binding with means for pulling a ski boot into the keeper means of the binding and to retain it therein by means of clamping devices, preferably being adjustable.  The means consist of a preferably U-shaped fixing strap arranged in guides on said keeper means, the upwardly extending free ends of the strap being coactable with holes in the front sole portion of the boot.  The transverse portion of the fixing strap is in engagement with the clamping device in such a manner that the free ends of the strap upon depression of a tensioning arm hinged to said keeper means pull the ski boot forwardly in the longitudinal direction and into the keeper means.              The clamping device incorporates a intermediate piece, preferably adjustable in length, which is hinge-connected to the tensioning arm and snapped onto said trans-verse portion at its other end.  The binding may be released by letting the front end portion of the intermediate piece be caused to tilt about a section above the top surface of the ski.            Figure 5.

Abstract: OVEN-TYPE APPARATUS AND METHOD             Abstract The problem of properly cooking food and hand-ling heated food so that it retains a fresh-cooked taste, fragrance and appealing appearance is solved by apparatus that includes an inner wall means (15) de-fining an inner chamber (16) and an outer wall means (17) defining an air circulating passage (18) extend-ing in a loop around the inner wall means.  Louvered slots (28) with inclined fins (29) are provided in the inner wall means along said air circulating passage that are sufficiently narrow to confine the circulat-ing air substantially to said passage without a signif-icant amount of airflow in direct contact with the food in said chamber and at the same time arranged to per-mit moisture and heat to diffuse between the circulat-ing passage in the inner chamber via said apertures to control the moisture and heat in the chamber and estab-lish a substantially uniform temperature throughout said chamber.

Abstract: TITLE OF THE INVENTION       Process and apparatus for producing composite building panels, and panels produced thereby ABSTRACT OF THE DISCLOSURE          In a process and apparatus for the production of composite building panels, bars are laid against a rotating drum, parallel to each other and close together. Parallel threads or wires which extend in the direction of the drum periphery are then wound around the outside of the bars, in a stressed condition, whereby the bars being transported by the drum are pressed against the peripheral surface thereof. The bars are connected by a hardenable binding agent to fibres and a thin sheet of suitable material which move with the drum, and the binding agent is caused to harden, thereby forming a first strip on the drum. me first strip is then brought into a condition of extending parallel to a second strip produced in the same manner, with an adhesive between the two strips. The two strips are then passed through a pair of rollers which press the assembly together, thereby forming an elongate panel configuration.

Abstract: IMPROVED DOUBLE TALK DETECTOR FOR         ECHO CANCELLERS   ABSTRACT OF THE DISCLOSURE      Three double talk detectors (DTD) are used in combination with an echo canceller having an adap-tive filter and a center clipper. First and second double talk detectors are used in the presence of double talk to selectively freeze the adaptive filter correction loop and to disable the center clipper.  The third double talk detector is used to detect the initial adaptive period of the echo canceller.  Control of the adaptive filter and clipper is effectively transferred from the first to the second double talk detector upon termination of the initial adaptive period as determined by the third double talk detector.  The third double talk detector also detects a false double talk condition (where the distant talker pauses in speech) and overrides the second double talk detector in order to maintain the clipper in an active state.

A switch member is retained in the chamber and has flexible guide means to position a first terminal of a battery in the chamber against a contact element in electrical con-tact with a first terminal of a lamp retainable in the chamber to direct light outwardly of the housing in the direction of the key.  The flexible guide means further biases the battery and a second terminal of the battery away from a further contact element in contact with a second terminal of the lamp.  The switch member has an actuable portion accessible from the exterior of the housing to displace the battery in a horizontal plane against the flexible guide means whereby the second terminal of the battery is positioned in electrical contact with the further contact element to cause an electric current to flow through the lamp and cause it to light.

Abstract: PHN. 9667.           ABSTRACT:                 A record carrier comprising a disc-shaped substrate with a radiation-sensitive information layer and provided with information areas arranged in accordance with a spiral or concentric track pattern.  The record carrier is intended for the recording and/or reproduction, via a radiation beam, of digitally coded information of fixed bit frequency in the information areas.  The infor-mation areas exhibit an optically detectable first periodic track modulation, whose period corresponds to a frequency for which the power spectrum of the digitally coded information substantially exhibits a zero point, for generating a clock signal of bit frequency during record-ing and/or reproduction.  In order to generate a radial tracking signal during recording and/or reproduction, there is superimposed on the first periodic track modula-tion a second periodic track modulation, in which the track position is modulated in a radial direction.  The period of the second track modulation is at least as the same order of magnitude as the period of the first periodic track modulation.

Abstract: ABSTRACT OF THE DISCLOSURE             Battery testing apparatus is provided for rapidly and automatically testing newly-manufactured electric batteries.  The apparatus includes a testing machine which has at least one station, and preferably two, at which the batteries are tested for voltage and current output. By using two stations, the test at each station can be shorter and the change in the current output of a battery be-tween the two stations helps to determine battery characteristics more effectively.  Each of these stations has a stop for stopping a battery and a clamping arrangement for holding the battery at the station.  Each station also has a pair of vertically movable terminal pads and a pair of horizontally movable terminal pads for top post batteries and side post batteries.  The apparatus also includes an entry conveyor which is effective to supply one battery at a time to the stations of the machine and to effectively stop and hold a line of batteries to be tested.  Adjustable, water-cooled shunts are also provided for the current output test.
