Abstract: ABSTRACT OF THE DISCLOSURE A device for generating a foam which might be used, for example, as a cleaning fluid.  As depicted, the device comprises structure which accepts a combined fluid, such as water, soap, and air, and passes it through a pair of turbulators in series.  As it enters the first turbulator, the fluid is forced to turn through a turbulence-generating angle.  The first turbulator may be sub-stantially filled with a turbulence-generating material providing a plurality of randomly sized and randomly oriented interstices through which the fluid must pass in traversing the turbulator.  The turbulence-generating material might, for example, comprise a material such as metallic or plastic turnings which are gathered together and fixed in place.  Fluid discharged from the first turbulator then travels in a relatively quiescent flow through a pipe or tube to a second turbulator which may empty the same type of material to gener-ate additional turbulence in the flow and thus assure complete mixing.  Prefer-ably, the material in the second turbulator is packed at about the same density as that in the first turbulator, but the second turbulator has a larger volume to allow the foam to expand.

Abstract: ROGERS, BERESKIN & PARR                  CANADA           TITLE:  PALLET RETRIEVING MECHANISM FOR         FORKLIFT VEHICLE           INVENTORS:  GERARDUS J. BROUWER             WILLIAM T. ARNOLD     ABSTRACT OF THE DISCLOSURE         A forklift vehicle has hooks mounted on the forks for preventing removal of a loaded pallet from the forks and a gate for ejecting the contents of the pallet as the forks are withdrawn.  The hooks are normally biased out of engagement with the pallet but a cam mechanism moves the hooks into pallet engaging position when the forks are moved to a selected unloading height.  The gate is mounted on the rear of the forks and is biased there by two pairs of extensible links. During unloading the forks are moved forwardly and downwardly to bring the gate in front of a pair of stops.  The forks are then moved rearwardly, withdrawing the pallet while the gate ejects the pallet contents. The forks are then raised above the stops, allowing the biased links to return the gate to its rear position.

Abstract: ABSTRACT      A patient (10) having cardiocirculatory arrest is resuscitated using a supple band (12) that is passed around the thorax (14).  The thorax is clasped at its side portions, for example, between contoured band-guide assemblies (16 and 18), one (16) being fixed and the other (18) adapted for traversing movement.  The band is guided, as by the assemblies (16 and 18), over the clasped portions of the thorax so that a tautening of the band exerts the clasping action and produces force components (62, 64, 66, 68) directed inwardly of the thorax around a major portion of its periphery.  The band is alternately tautened and loosened, for example, using a pull roller (72) driven manually through a torque-measuring wrench handle (110) or by a motor device (170).  The tautness of the band may be limited as by an adjustable mechanical stop arrangement (128, 130, 132).

Granted: 1985-07-16
Abstract: 11 ABSTRACT OF THE DISCLOSURE The retransmission equipment comprises an automatic control circuit of the image/sound ratio in the television signal. This RAC circuit placed between the intermediate frequency translation mixer and the intermediate frequency amplifier comprises a power distributor between an image channel and a sound channel having respectively an image filter and a sound filter, couplers and an output adder connected to the main outputs of the couplers. The sound channel also has a variable gain amplifier, whose gain is controlled by an error signal, so as to keep the image/sound ratio constant. This error signal results from the comparison of the detected amplitudes of the image and sound components sampled by the couplers in the two channels. This circuit also permits the correction of the cross modulation resulting from non-linearities of amplifiers by the control of the same variable gain amplifier.

A digital job description of a form is created (Fig. 6), including location of printed images on several parts of the form and location of process items, e.g. perfora-tions, holes, or cuts on parts of the form.  This job description is stored in the memory of a com-puter PR-2 with a job identifying code.  Also, a digital description is created of images to be printed on the form, and stored in memory with the job identifying number.  The image descriptions are recalled from memory and used to create printing plates for the presses and to pre-set printing and processing sections of a press for each part of the form.  The parts of the form are then produced on the presses and supplied to the collator.  The job description is recalled from memory and used to pre-set stations of the collator to assemble and complete processing of the multi-part forms.  The computer also gathers and stores management data as the presses and collator operate, keeps a record of supplies/tools needed for each job and makes this information available to operators through ter-minals, and maintains records of jobs entered, work in process, and jobs shipped.

Abstract: ABSTRACT          An improved barge and tug connection apparatus com-prises a barge having a V-notched portion for receiving a tug into the V-notch.  A tug for pushing the barge is disposed during operation within the notch allowing the tug to pitch and heave in the notch relative to the barge responsive to wave action.  An articulated bow fender attached normally to the bow of the tug and disposed during operation between the bow of the tug and a portion of the notch of the barge longi-tudinally spaces the barge from the bow of the tug.  The arti-culated bow fender maintains a substantially constant horizontal spacing of the barge with respect to the tug in a longitudinal. direction while allowing both the tug along its entire length to pitch and heave with respect to the barge responsive to wave action.  A plurality of side fenders affixed to the tug hull bear outwardly to abut the barge inside the V-notch, the side fenders are positioned to bear and slide against the barge on a provided bearing surface responsive to lateral and verti-cal relative movement between the tug and barge.  The side fenders feature hydraulic pads which are inflatable to a desired pressure and normally absorb lateral forces between the tug and barge.  The inflatability of the pads affords lateral movement to the side fender wear surfaces.  Thus, the pads can be deflated, providing a clearance between the tug and barge during placement/removal of the tug with respect to the notch.  When the tug is fully in the notch, the hydraulic pads are inflated to a desired predetermined pressure and the clearance between tug and barge bearing surfaces is cancelled. Absent pressurization, the pads collapse responsive to urging by provided return springs.  The pads are preferably of a steel reinforced rubber construction.
