Abstract: Inventor:   Karl HEHL          Invention:  MULTI-PIN MALE AND FEMALE CONTACT BARS            AND MANUFACTURING METHOD                        A B S T R A C T    Multi-pin male and female contact bars with composite contact posts having U-shaped upper contact post portions with two spaced tines and a transverse web portion to which is butt-welded a pin with an enlarged attachment head.  The tines serve as spring tines of female contact members, or as cable-penetrating contact blades of male contact members, the associated butt-welded pins being solder pins for connection to a printed circuit board or male plug pins, respectively.          The upper contact post portions are produced as die-cut seg-ments of a sheet metal strip which remain connected to a car-rier strip, until inserted into the contact post housing of the contact bar and severed from the carrier strip by a break-away movement.

Abstract: ABSTRACT A roll for a foil-drawing calender or the like which is substant-ially solid, has a central longitudinal bore hole and has journals supported in outer bearings in a roll stand.  In the longitudinal bore hole is a stationary core which is supported, at axial locations corresponding to the ends of the working width, via inner bearings in the longitudinal bore hole and is braced via a hydraulic force-exerting arrangement acting in the working plane of the roll in a direction toward the roll gap and against the inside circumference of the longitudinal bore hole.  In the vicinity of the inner bearings and in the region of the outer bearings, load-relieving hydraulic force-exerting arrangements are provided which brace the core against the inside circumference of the longitudinal bore hole and act in the action plane of the roll in the direction opposed to that of the other hydraulic force-exerting arrangement.

Abstract: A B S T R A C T     A ski tow comprises a guide pipe guiding a string transmitting a towing force to towing means attached to the string at suitable intervals.  Instead of being a tension element like a wire, a rope or the like, which is conventional in known ski tows, the string consists of separate pressure elements, each having at either end an end face contacting the opposed end face of an adjacent element, whereby the towing force is transmitted by pushing the string, which is accordingly subjected to a compression force.  The size and shape of the end faces are such that at any possible angular position of two adjacent pressure elements due to tolerances between the guide pipe and the elements and /or to curves in the load towing section of the guide pipe, the point of contact between the contacting end faces lies to the side of a notional straight line extending through the centres of said two adjacent elements opposite from the point of intersection between the longitudinal notional axes of said two adjacent elements.  Thereby, the string of pressure elements when subjected to a compressive force due to advancing the string by pushing, will tend to form a stable,  straight column, which column is still free to fold when required by curves in the guide pipe.

Abstract: ABSTRACT     An air oven having a heating space accessible through a hinged door provided with material holding means for holding, and optionally rotating, materials to be cooked solely by hot air supplied by electric heaters in a recirculating duct that removes air from the heating space at one end thereof passes it over the heaters to heat it to high temperature suitable for rapid cooking of the materials to be cooked and introducing the hot sir into the other end of the heating space to envelop with swirling action the materials to be cooked.  The swirling motion is imparted to the air in the heating space by introducing it through a nozzle plate having nozzles directing the jets of air flowing through them at an angle in two planes at right angles to each other with respect to the axis of rotation of the material holding means.    Preferably part of the air in the heating space is removed and exhausted to atmosphere through a filter to take out odors and particles before exhausting the air.  The material holding means may take a number of forms, including a rod to serve as a spit for cooking meat roasts, whole chickens, and the like; a foraminous platform for supporting steaks, chops, baking potatoes, and the like; and one or two foraminous baskets for holding small pieses of materials to be cooked such as clams,  shrimp,  chicken parts, potato pieces to make French fries, and the like.  Air cooled electric motors are provided to drive fans to cause air to flow as needed and to rotate selectively the material holding means.  The  interior walls of the heating space may be protected against deposit of grease thereon by a removable insert which,  in effect, lines each interior wall with a metal sheet.  The insert is readily cleaned by removing and immersing it in a cleaning bath. The entire operation of the oven is preferably automatically controlled by electronic control means.

Abstract: DUAL INCREMENTOR                         Abstract A "lookback" carry function is implemented in 2 binary incrementor.  In contrast to conventional lookahead carry functions, the present "lookback" carry function implements an actual carry during the incrementing operation.  After the carry function has been implemented at each register position, a subse-quent determination is made as to whether each carry function was a valid one and should have been carried out.  With respect to any carry functions which were not valid, subsequent circuitry will eliminate such carries to leave the appropriate carry pattern in each position of the register.  In order for a carry to be considered valid, the incrementation of all bits of a lower order must have resulted in a carryout.

Abstract: ABSTRACT               SEQUENCE CONTROLLER      The invention is concerned with the problem of time-lag arising in heating systems using a plurality of boilers which are successively switched in or out according to load requirements, and provides that during times of increasing load when an additional boiler is required, that boiler is initially switched in at a low setting and at the same time a previously switched in boiler is reduced to low setting.          This may reduce unnecessary switching in and out particularly when the structure of the previously switched in boiler is not at normal operating temperature at the time when the next boiler is called in.

Abstract: Abstract Gas separation A raw ammonia synthesis gas, preferably containing an excess of nitrogen, is converted to synthesis ready ammonia synthesis gas by two pressure swing adsorption (PSA) stages operated in succession.  If the raw gas contains carbon monoxide this is chemically removed, eg by methanation between the PSA stages.  In the first PSA stage, CO2 is removed and waste gas from the second PSA stage is preferably fed back to the first PSA stage for sweeping, purging or repressurising.  In a preferred system the first PSA cycle includes a sweep with CO2-rich gas prior to depressurisation and purge with second PSA waste gas.  In the second PSA stage inert medium boiling gases, and any unwanted nitrogen are removed as the waste gas.

Abstract: SECOND ORDER TOROIDAL MICROPHONE        Abstract A second order gradient microphone arrangement is implemented with four commercially available, inexpensive first order gradient electret microphones which are arranged in the wall of a hollow cylinder at ninety degrees angular spacings and whose outputs are added to produce a toroidal directional characteristic.  The distance between the tops of the microphones and the top of the cylinder equals the distance between the bottoms of the microphones and the bottom of the cylinder.  The directional characteristic is relatively frequency independent.  The arrangement is characterized by rotational symmetry around the cylinder axis and further by a cosine squared dependence in the planes containing the rotational axis. In the direction of the axis, the sensitivity at midfrequencies is typically twenty decibels lower than in the equatorial plane.  The equalized frequency response in this plane is within ?3 dB from 0.3 to 3 kHz.
