Abstract: Abstract A skid steer loader comprising an improved loader main frame and including an operator's compartment designed to present a low profile vehicle particularly suitable for low clearance applications. The loader main frame includes a center compartment partially defined by a pair of longitudinally extending, laterally spaced side beams.  The engine for the vehicle is mounted at the rear of the center compartment and is acoustically enclosed by structural elements of the frame.  A seat pan mounted on the side beams overlies the engine and transmission and separates the operator compartment from the center compartment.  At a forward end of the center compartment an elongated transmission case forms a partial system of the vehicle.  The side walls of the transmission case are displaced from the side walls of the frame, enabling the operator to straddle the case, thus reducing height requirements for both the operator compartment and the overall vehicle. Uprights secured to the side beams of the main frame at respective outer rear portions thereof partially enclose the rear portion of the center compartment and boom loader arms are secured to upper pivotal mountings provided on the uprights.  Respective front ends of the loader arms are arcuately proportioned to extend forward of the wheels of the vehicle.  An improved attachment mounting means incorporating a single mid-plane cylinder is provided between respective outer ends of the loader arms, the loader arms also carrying attachment means for implements used with the vehicle.  A low profile overhead guard specially fabricated encloses the operator compartment and completes the assembly.

Abstract: BALL BEARING CAM ASSEMBLY                        ABSTRACT A cam assembly is disclosed which is used for the selection of different track positions for a magnetic tape head in a magnetic tape player/recorder.  The tape track position of a magnetic tape head is determined by the position of a cam follower member which is selectively positioned with respect to a reference surface by selectively positioning a number of different diameter ball bearings between the cam follower member and the reference surface.  Specifically, a solenoid actuated armature causes the linear movement of prawl members which in turn rotate a ratchet wheel member.          The ratchet wheel member forms part of a cam apparatus that includes four ball bearings of different diameters.  Sequential rotation of the ratchet member selectively positions ball bearings of different diameters between a non-rotatable reference surface and the cam follower member.  Thus an accurate and inexpensive cam positioning mechanism is disclosed which uses precision ball bearings instead of an expensive cam having precisely formed surfaces to implement precise magnetic tape head position changes.

Sontheimer :  Richard D. Clare ABSTRACT OF THE DISCLOSURE Method and apparatus for conversion of an uneven arm beam balance from metric weight measurement to English weight measurement, and the reverse conversion are described.  An il-lustrative example is a balance rated to measure in kilograms and having a main beam scale graduated in uniform increments of metric weight with associated notched poises, a main weight being discretely positionable in respective notches.   A second-ary beam scale in parallel relationship with the main beam reads from zero to a value equal to one such metric weight in crement, along which a secondary (slider) weight is slidable for making the fine-tuning weight measurements between res-pective graduations of the main scale.  For conversion, there is also provided on the main beam a main English scale graduated in uniform increments of English weight with asso-ciated notched poise arranged so that a shift in the position of the main weight by a distance equivalent to 400N Grams weighs an increase of N pounds Avoirdupois.   For performing a measurement in pounds, the main weight is increased by 13,398% accomplished by combining an auxiliary weight there-with or by substituting a heavier main weight.  A secondary English scale is also provided reading from zero to a value equal to one such increment of English weight and having a length 13.393% longer, or a slider 13.398% heavier, than for the secondary metric scale.  In another illustrative example, a shift in position of the main weight by 2N pounds weighs an increase of N Kilograms, the main weight being increased by

Abstract: ABSTRACT                  A digital switch for switching word formatted PCM digital data is disclosed.  The data of each PCM word is serially bit switched rather than being switched in parallel as in con-ventional PCM switches.  This is achieved by time multiplexing corresponding word bits of respective incoming channels or inlets onto a single data highway to form a bit interleaved digital bit stream.  Data on the highway is switched through a RAM under control of a control memory according to the required connections so as to rearrange the order of the data bits.  The rearranged data is demultiplexed to the respective outgoing channels or outlets.  To avoid loss of alignment of word boundaries at the outlets, as between respective channels, the switch determines those connections which incur a switch cycle delay relative to those which do not.  This is done by comparing the read and write address controlling the switch memory and when the write address is equal  to or greater than the read address the particular bit being switched is delayed on the highway by one cycle. In the con-verse situation the delay has already occurred in the RAM and no further delay is introduced.  The delay is caused by a delay equalizer circuit including a further RAM which receives all data on the highway and introduces a one cycle delay thereto.  A by-pass connection enables data on the highway to by-pass the further RAM and hence avoid the delay.  An AND/OR select gate selects data from the further RAM or the by-pass connection as the case may be. Thus all data through the switch incurs an equal delay.  A synchron-ization signal at the switch input, for word aligning the data, is delayed by one cycle at the switch outlet.  A method for switching data is also claimed.

Abstract: C-2904 D-1,150 VEHICLE OPERATOR SECURITY SYSTEM Abstract of the Disclosure A portable infrared signal generator is actuatable by a motor vehicle operator at a distance from the vehicle to generate digitally coded infrared signal pulses in accordance with either a first or a second predetermined digital code. A receiver on the motor vehicle is effective to receive the infrared signal pulses, decode them and actuate apparatus responsive to the first digital code to unlock a power door lock and power a light effective to illuminate at least a part of the vehicle or responsive to the second digital code to actuate an alarm. Both the first and second digital codes contain a common identifying portion substantially unique to the particular motor vehicle, which portion may be permanently stored in the generator and receiver by the connections of the input/output terminals of a microprocessor chip mounted on a printed circuit board to one of two voltage sources on the printed circuit board. The receiver includes a photodiode connected in a circuit to operate in the photovoltaic mode so that the infrared pulses can be distinguished from strong back-ground illumination for operation in daylight as well as at night. The receiver further includes a lens and reflector for receiving the infrared pulses over a wide incoming angle. The apparatus may include a sleep mode in which the reception of a predetermined number of signals not containing the code unique to the motor vehicle actuates apparatus to prevent unlocking of the doors and to actuate the alarm.
