Abstract: COMBINATION HYBRID AND FREQUENCY DIVISION    MULTIPLEXING CIRCUIT AND METHOD by Lawrence E. Getgen ABSTRACT OF THE DISCLOSURE           A terminal having a plurality of lines in a two-way communication system.  A plurality of resonant transfer means is used for effecting hybrid separation of the several lines into individual transmit and receive paths.  The several hybrids use resonant transfer gates and bandpass filters selecting different portions of the frequency spectrum.  As a phenomenon of the system, the line signal, e.g., voice current, is repeated as sidebands located at multiples of the sampling frequency of the resonant transfer gates.  Frequency division multiplexing of the hybrid paths is accordingly attained.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the manufacture of non-foaming aqueous suspensions of polyolefin fibrids using suitable dispersing agents. These are obtained by polycondensation of 1 mole of melamine, from 1.8 to 3 moles of formaldehyde and from 0.1 to 0.5 molar portions of amino carboxylic acids or alkali metal salts thereof. Very small quantities of said dispersing agents are sufficient to finely disperse the hydrophobic polyolefin fibrids in water and to prevent the formation of foam in the manufacture of web structures of a paper-like and textile-like nature. The aqueous suspensions of polyolefin fibrids may also contain cellulose fibers.

Abstract: Abstract of the Disclosure Method and apparatus for deep frying of chicken serving pieces in which the chicken serving pieces are immersed in cooking oil contained in a cooking chamber having a valve controlled dis-charge outlet at its lower end, and a filter unit within the cook-ing chamber through which the oil flows on being discharged from the chamber, in which, when filtering of the cooking oil is de-sized, the chamber is sealed as for pressure cooking and is con-nected to a source of compressed air for pressure discharging of the cooking oil through the chamber outlet, and thus through the filter unit, into a holding container located at atmospheric pressure conditions, after which the chamber is opened for clean-ing purposes and cleaning and replacement of the filter unit. After the filter unit replacement is applied to its operating position within the chamber, the chamber is again sealed as for pressure cooking purposes and then is connected to a  source of vacuum to enable atmospheric pressure acting on the oil to return the oil to the chamber through its outlet and the filter unit, whereby a second filtering of the reusable cooking oil is obtained. Enough new cooking oil is then added to the cooking chamber to bring the cooking oil level up to its desired level.

Abstract: ABSTRACT OF THE DISCLOSURE       In programmable timing apparatus forming an electronic appointments reminder, a support formed by an insertable sheet or an insulating surface receives markings made with conductive material or by punched holes at locations corresponding with predetermined times in a given period.  Each marking makes or interrupts an electrical connection between a conductive path and a bus-bar.  The locations are designated by characters which indicate the respective hours and predetermined intervals in minutes of the given period.  Switches driven by a rotating cam disc derive sequential timing signals at predetermined inter-vals during the given period.  Apparatus is provided for auto-matically and sequentially responding to correspondence between the timing signals and the predetermined time represented by the respective marking to provide a respective time related out-put signal which is used to operate and electronic alarm.  Pro-gramming positions may be provided in which conductors definer gaps which are closed by conductive marking material which is applied when a number is written into the programming position. Coded signals are thereby derived representing the number which has been written.  Electronic timing displays are also used and a memory may be incorporated to store data read from markings made on the support.

Abstract: ABSTRACT OF THE DISCLOSURE A process and apparatus for blow-molding hollow bodies in a mold having half-molds which are closed along a mold joint during blow-molding and are laterally displaced with respect to one another to open the mold for removal of the formed hollow body.  The half-molds are shaped to form a concave bottom on the hollow body and when the half-molds are opened they impose a translation movement on the hollow body.  A plug is formed at the bottom of the hollow body during molding which plug is seized by pincers prior to the opening of the mold such that the hollow body is supported by the pincers during mold opening.  The pincers are displaced during mold opening, in translation parallel to the plane of the mold joint, over a distance at least equal to that imposed on the hollow body by the half-molds during opening of the mold.

Abstract: A B S T R A C T           A method and apparatus for inspecting the location and orientation of a sensor assembly in a tray-sensor arrangement adapted to be placed in a microwave oven.  The sensor assembly which includes a ferromagnetic element that absorbs energy when placed in the oven and changes its characteristics when a pre-determined amount of energy has been absorbed, is tested in the completely assembled tray by accurately position-ing the tray in predetermined relation to an oscillating circuit whose operating frequency is responsive to the presence of the ferromagnetic sensing element.  The out-put frequency of the oscillating circuit indicates whether or not the sensor assembly has been properly assembled and positioned on the tray.  The oscillator circuit includes a frequency determining element which produces a dis-tinctly different frequency when the sensor is not properly positioned in the assembly or is omitted form the assembly.  The output frequency of the oscillating circuit is supplied to an electronic meter such as a counter or frequency meter to display the operating frequency, or acceptable range of frequencies, to pro-vide an indication of the acceptability of the sensor assembly and tray.

Abstract: ABSTRACT OF THE DISCLOSURE       The specification describes a control circuit for a self-starting electric motor with at least one stator winding having an electronic servo-element which is applied in series therewith to a DC operating voltage. The control circuit acts as a switch and is controlled by control impulses supplied to one input of a gate circuit whereby the gate circuit during normal operation is constantly turned on in response to a "normal-running"-signal. The gate circuit during the starting period and when the rotor is blocked is alternately supplied with relatively short starting signals as opening signals and longer stopping signals as blocking signals from an impulse generator. The impulse generator is independent of the "normal-running"-signal generator. The blocking signals during normal operation are overridden by the "normal-running"-signal.
