Abstract: ABSTRACT         An arrangement to provide variation of the speed or other operating parameters of two or more coupled electrical machines without connection to the rotors.  The machines are of the induc-tion type each having a winding in separate parts to create a flux movable in the air gap at different speeds by the alteration of current in a part of the winding.  The rotors of the machines are coupled to a common mechanical load without rigid connection.          The two machines (NM1, NM2) may be arranged to drive a rail vehicle through smooth rail wheels attached to the machine rotor axles.         A single, variable-frequency, inverter (NI) drives both machines and is connected to part (MP) of each machine winding.  Other parts (AP) of each machine winding are connected together by a link (NC).  In operation power (real or reactive) is transferred between the machines along the link to equalize the torque of the machines.  Run-away of one machine while the other stalls is thereby avoided.  Such run-away could occur if two machines are simply connected to a common inverter supply.

Abstract: TARGET PRACTICE DEVICE FOR HOCKEY AND THE LIKE     ABSTRACT OF THE DISCLOSURE         The only way a player of hockey or the like can practice shooting at goal is to utilize the conventional net or a stationary target.  The net is too large for accu-rate practice and shooting at a target is difficult to moni-tor.  In both cases, no indication of the speed of the shot or the impact velocity can be ascertained.  The present in-vention mounts a target plate on the front end of a carriage supported upon rails with the movement caused by the impact of the puck or the like, being restricted or controlled by a spring.  If the shot hits the target with a velocity above a predetermined minimum, the target and carriage are moved rearwardly within a casing and are latched incrementally depending upon the velocity of the shot.  This incremental latching actuates a switch which indicates the approximate velocity upon impact, by means of a lamp or the like on the front of the casing.  A bell also may be rung.  After a pre-determined time interval, the carriage is unlatched and the spring returns the carriage and target to the original posi-tion.   The time delay is so that the player or coach can view the display and this time delay can be adjusted.  If the shot hits the target with insufficient velocity to reach the first latch, then the spring returns the carriage to the forward position immediately.  The device can be powered by a re-chargeable 12-volt battery or any other source of electrical power depending upon design conditions under which it may be used.

Abstract: Abstract An electro-optic welding lens assembly for the use in a welder's helmet or protective eyeshield comprises a filter arrangement with at least one liquid crystal light shutter element and a con-trol unit for changing the transmission rate of the filter as-sembly in response to ambient light conditions. The light sen-sing element used to control the transmission of light through the filter arrangement is simultaneously an opto-electric trans-ducer,  supplying power to the control unit and the light shutter element. Thereby, there is no need for an additionalpower supply like a battery. If the sensing and transducer element is ar-ranged behind the light shutter element, a self-regulating loop can be realized to continuously vary the transmission rate of the filter arrangement and thereby to keep the viewing illumi-nation through the lens assembly essentially constant.

Abstract: ABSTRACT:     "PARALLEL-SERIES ACOUSTIC WAVE DEVICE ARRANGEMENT" N2 acoustic wave devices (A,B,S,T;  where N is an integer  greater than unity) with substantially the same electrical impedance and transfer characteristics are electrically connected in a parallel-series arrangement which has substantially the same electrical impedance and transfer characteristics as anyone of the individual N2 devices, but an increased active device area.  The increased active area reduces stress and alleviates acoustically-induced  migration in the metal of, for example, transducer electrode fingers (6,7) of resonators at high power levels.  The parallel-series arrangement consists of N groups each of which comprises N devices (A,B or S,T) the corresponding pairs of terminals (4,54 and 54,55) of which are connected in series. Some terminals (54 or 55) may be common to two or more devices and some devices may have merged transducers in which the electrode fingers (6 or 7) of one transducer are a longitudinal extension of the fingers of a parallel transducer.  In the case of multi-port devices the input and output terminal pairs may be differently grouped, as regards the individual devices to which they belong.           (Figure 5)

Abstract: HOT AIR HEATING SYSTEM             Abstract of the Disclosure A hot air heating sytem utilizing the otherwise wasted heat and moisture in the gases of combustion to pre-heat and humidify the room air.  The hot flue gases discharged from the furnace are mechanically induced by a blower to pass through an auxiliary heat exchanger in countercurrent flow to the cold air being returned from the rooms to the furnace, thereby pre-heating the return air and cooling the exhaust combus-tion gases.  The products of combustion include a con-siderable quantity of water vapor.  Cooling these gases results in condensation of this  water, which is then collected in a sump and utilized to humidify the room air.  Condensation of the vapors releases their latent heat of vaporization adding considerably to the heat recovery of the system.  Because the water does not contain any minerals the humidifier does not have the usual problems of mineral deposit build-up.
