Abstract: A tunnel type bakery oven 1 comprises an endless conveyor 2 for conveying loaves 5 from the entrance end 3 to the discharge end 4 of the oven. To provide a lateral support for the loaves so that they cannot flow out laterally, lateral supports 6 are disposed along the longitudinal edges of the conveyor. These lateral supports may be each composed of several hingedly interconnected supporting members 8 in the form of generally parallelepipedal sheet-metal boxes retained on the conveyor by magnetic forces. The box-like supporting members of each lateral support travel in an endless path through the oven together with the conveyor in the direction A from the entrance end 3 to the discharge end 4, whereupon the supporting members, via guide pulley structures and a conveyor belt or the like, travel back to the entrance end 3 in the direction B outside the oven. <IMAGE>

Abstract: The recording apparatus comprises a video signal input (5a), a video monitor (2,5 to 12) connected thereto for converting the received video signals into images displayed on a screen of the monitor, support means for a photographic medium (4) to be exposed to the images displayed by the monitor (2,5 to 12), and an optical system (3), such as a wide angle lens, operatively interposed between the screen of the video monitor (2,5 to 12) and the photographic medium (4). A compensation circuit (13) is connected to the monitor (2,5 to 12) to modify the brightness of the image displayed in such a way that it complements the illumination characteristics of the optical system (3) whereby the image recorded on the photographic medium (4) exhibits negligible or zero vignetting. The intensity of light transmitted through a wide angle lens varies as COS<4> gamma where gamma  is the angle of illumination with respect to the lens axis. Double integration circuits (14,15) generate parabolic signals at line and field rate which are combined and used to control the bias of the control grid (7c). <IMAGE>

Abstract: An improved ternary noble metal-containing, alloy catalyst which has a catalytic activity for the electrochemical reduction of oxygen greater than two and one-half times that of the supported unalloyed noble metal alone. In addition, a disclosure of the method of preparing said catalyst is by intimately contacting two metallic elements with a supported noble metal, then heating this material to form the ternary alloy catalyst. This catalyst has particular utility for the electrochemical reduction of oxygen which makes it particularly useful as a cathode in acid fuel cells. The preferred embodiment of this catalyst is finely divided platinum alloyed with chromium and cobalt supported on an electrically conductive carbon-black support material.

Abstract: An Optoelectric connection device (3a) for coupling transmission (28) and reception units (4) to a line (2) for optical information transmission. The device includes a plate (11) of optoelectric material having two directional couplers (12,13) connectable to the line (2) and a modulating directional coupler (14). A signal at the input (18,18a) for the line is cross-coupled in the first coupler (13) to the reception unit (4). A lightwave from the source (28) is modulated in the modulator (14) to form an output signal, which is cross coupled in the second coupler (12) to the output (23,23a) for the line. If the directional couplers (12,13a) are disabled, a signal at the input (18,18a) passes via the couplers directly to the output (23,23a). The connection device has a reserve input (19,19a) and a reserve output (24,24a) which are utilized for fitting the connection device into the line (2) without interrupting signal transmission on the line (2). The device (3a) has negligible cross talk between the input (18,18a) and output (23,23a).

Abstract: The invention relates to a self-propelled grinding or milling machine for finishing a surface of concrete or similar hard material, eg a floor. 
<??>The machine, which consists of a frame carried on a number of wheels in which a rotating grinding or milling tool with a vertical shaft is suspended and loaded with weights so that the pressure of the wheels on the surface is maintained at a constant level at varying working pressures of the tool, is arranged to tilt laterally by means of a raising and lowering device which acts on the non-steerable wheels so that the pressure of the tool on the floor differs on the right-hand and left-hand side and so gives rise to frictional forces which cause the machine to move forward and rearward respectively at a speed which is dependent on the magnitude of tilt.

Abstract: Finely dispersed epidermal/dermal tissue from mammals, which is prepared raw, frozen and finely dispersed or "scalded", dried and finely dispersed and which contains all the known moisture-preserving substances in the epidermis/dermis and 10% unknown such substances, and also proteins with all essential amino acids and metals of the iron and zinc types, has been able to be used, with a surprisingly good effect, as moisture-preserving and exudate/moisture-preserving element in dermatology, cosmetics and wound-healing. The epidermis/dermis mixture as such, or in another form, or as additive to different vehicles, retains its water-adsorbing, moisture- preserving properties. By adding further water-binding substances, such as polyphosphates and sodium chloride, the water-binding ability of the epidermis/dermis powder can be further potentiated, which makes it particularly suitable for use in dermatology, cosmetics and wound- healing when large amounts of exudate have to be adsorbed.

Abstract: This apparatus ensures improved dissipation of heat from the condenser for the refrigerating cycle. This result is attained by having a blower mounted coaxially with the shaft of the mixing paddle but freely with respect thereto; the blower is driven by the motor at a much higher speed than the mixing paddle. Furthermore, in order to best utilize the air flow from the blower, the condenser is ducted within a shrouding case.

Abstract: A device for fixing an object (2) on a supporting surface (3) and having means (14,15,16) for adjusting the position of the object (2) comprises a lower part (6) for fixing against the support surface (3), and upper part (7) for mounting on the lower part (6), and locating means between the two parts (6,7) for determining the relative position therebetween in two mutually perpendicular directions in the dividing plane between said parts. The locating means consists of parallel locating strips (17,18) placed on either side of a rectangular cavity (8) in the lower part (6). The position of the upper part (7) relative to the lower part (6) in each direction is adjusted by replacing the two locating strips (17,18) with two other ones of the same composite width but another width ratio between themselves. The upper part (7) is also fixed by means of a fastener (31) to the lower part (6) and the supporting surface (3) and has means (5) for fixing the object (2). Spacers (14) between the lower and the upper parts (6,7) permit adjustment in a direction perpendicular to the dividing plane between the two parts (6,7).

Abstract: In automatic multi-run welding of a butt joint (37), for example a V-type joint, U-type joint, a sensor (44) oscillating transverse to the weld joint scans at several joint portions (F1, F2) a number of points (41, 41a, 41b etc.) on the contour of the joint. The coordinates of the points are determined for two directions, preferably in the vertical direction and lateral direction of the joint. The points are corner points of a polygon whose area is nearly identical to the cross-sectional area of the joint. Welding parameters, for example the welding speed, which control the amount of welding material per unit of length in a bead to be deposited in the joint are determined for the different joint portions (F1, F2) as a function of the corresponding polygon area. By virtue of the adaptation of the parameters to the varying joint cross-section, the joint is filled uniformly despite deviations in the shape of the joint from the ideal shape. Moreover, these polygon areas are used to determine the required number of beads per layer and the condition for deposition of a top layer with which the welding is finished.

The flow controlling means and the temperature controlling means are adjusted for a rapid reduction of the temperature during a predestinated period of time. After this period of time has lapsed, these means are reset to provide a temperature level which is lower than the original value which existed before the reduction in temperature was started. <MATH>
