Abstract: Method and Apparatus for Folding Sheets of Paper Abstract of the Invention A method and apparatus for sequentially forming folds in a sheet of paper which is continuously moving in a single plane.  A first fold is formed in the center of the continuously-moving sheet of paper and subsequent pairs of folds are sequen-tially formed, one on each side of the previously-formed folds, until the entire continuously-moving sheet is folded.  Guide wires retain each folded section until the entire sheet is folded.

Abstract: PROCESS FOR FROZEN PAR-FRIED POTATOES                    ABSTRACT   A process for simulating the taste and texture of deep fat fried potatoes has been developed.  The process  consists  of  having  the  potatoes  washed, peeled, trimmed, sorted, cut, blanched, or otherwise processed  in  conventional  manner,  and thereafter starch coated,  oil  soaked,  par-fried and frozen. This process produces  an improved potato product that more closely approximates deep fat fried foods. Most  preferrably  the  potato  comestible  will  be heated on a heat transferring apparatus.

Abstract: TOUCH POSITION LOCATING ARRANGEMENT            Abstract In a touch position locating system comprising a member to be touched and a touch sensing device, a mounting arrangement is provided for transferring the touching force through a point of action, e.g., the tip of a conical member disposed between the sensing device and the touched member.  The mounting arrangement provides a precise location of the transmitted force with respect to the sensing device, thereby improving accuracy of the touch position locating process, and avoids the application of distorting stresses against the touch member.

Abstract: METHOD OF CONTROLLING A REHEAT FURNACE TO    CONTROL SAID MARK EFFECTS                 ABSTRACT OF THE DISCLOSURE A method for controlling, in a reheat furnace of the type having a heat zone through which metal work pieces are moved over support skids and a soak zone in which slab temperature differentials are reduced, the variations in deformation resistance of the workpiece due to temperature gradients produced by the skids.  This method first provides for establishing, for the furnace and the workpiece to be rolled, an initial skid mark characteristic expressing, at the time the workpiece leaves the support skids and enters the soak zone, the ratio of the deformation resistance of the workpiece in  a region immediately contiguous the skids to the deformation resistance of the workpiece in a second region which is located approximately mid-way between adjacent skids.  A skid mark decay characteristic defining the decay of the skid mark characteristic as a function of time elapsed after the workpiece has left the skids is then established.  From the use of the decay characteristic and the initial skid mark characteristic, the time the workpiece should remain in the soak zone in order for the workpiece to achieve satisfactory properties for subsequent rolling operations is determined.         Adaptive updating of the skid mark characteristic may be achieved by observing the actual forces occuring during the rolling process.  The skid mark characteristic provides an indication of the condition of the support skid insulation and may assist in planning of furnace maintenance.

Abstract: ABSTRACT OF THE DISCLOSUR     Equimolar amounts of phenol and formaldehyde may be prepared from oxygen and toluene.  The catalytic oxidation of toluene, when carried out in the presence of acetic anhydride, forms phenyl acetate and methylene diacetate.  Pyrolycis of these two intermediates yields phenol and formaldehyde.     Significant improvements in this process are achieved when the first stage of the reaction is carried out in the presence of MoO3.     In a further embodiment of this invention it has been found that Group VIII dithiosemibenzil compounds, part-icularly nickel dithiosemibenzil, serves as a superior pro-moter for the toluene oxidation reaction.     In still a further embodiment of this invention it has been found that persulfate promoters such as potassium persulfate, persulfuric acid, or Caro's dry acid are parti-cularly effective promoters for the toluene oxidation reaction.           In a like manner, hydroquinone or resorcinol may be obtained from cresyl acetates.           In a further embodiment of this invention it has been found that benzylidene acetate may be converted to phenyl acetate and methylene diacetate by acid-catalyzed reaction in the presence of oxygen and acetic anhydride.

Abstract: ABSTRACT OF THE DISCLOSURE           In a preferred form of the present invention, there is provided a combined microwave and grill heater oven.  Two sensors, typically, a gas sensor and a heat-sensible element (i.e. thermistor) are provided.  The gas sensor, from timewise variations in terminal voltage provides information to a micro-computer to permit it to determine the type of food being heated and optimum terminal voltage.  The thermistor, from timewise variations in terminal voltage, may provide information as to compensations desirable due to the weight of food.  A single switch common to all foods is provided for operation of auto cooking.  A termination of heating instruction is issued when both the gas sensor and the thermistor reach their intended final levels.  Furthermore, a compensation value is evaluated from the rate of timewise variations in the output from the heat-sensible element.  After the microwave heating has been completed, grill heating is performed for a length of time which is determined by the compensation value.

Abstract: ABSTRACT OF THE DISCLOSURE            A two-piece lid for closure of a container neck with a thread or undercut shoulder having a lid member formed of a metal and a separate safety ring formed of synthetic mate-rial. The ring has an upper part and lower part, with the upper part positioned inside a sidewall protrusion which is provided at the lower edge of the lid member.  In order to make the safety ring undamageable, the ring can be shrink-able in its lower part.  On the other hand, the upper part of the safety ring can be formed as an outwardly directed edge and the lower part can be formed as an inwardly obli-quely directed lip, so that the ring has a substantially Z-shaped cross-section.  In both cases, there are no parts protruding over the protrusion of the lid member, where the ring could be damaged unintentionally.  If the safety ring also is stressed, either by separated elongation tongues on the inside of the lower part or by deformation of the upper part of the ring obliquely upwardly into the inside of the lid member portion, the separated, torn open parts of the lower part will spread to the outside away from the con-tainer neck after opening of the lid.  These torn open parts cannot be pushed back inwardly to mislead a following user of the lid that the container is still unopened.  In order to push the lower part of the ring over the container neck with less effort during assembly, the lower part is provided with toothing facing and engaging grooving formed on the outer parts of the safety ring.
