Patent CA-2081863-A1 (CA)
Inventor: ICHIHARA MASAKI
IPC: G01R25/00
Filed: 1992-10-30
Abstract: A phase detector comprises a ramp voltage generator for receiving a reference pulse of a constant frequency and an input pulse and producing a ramp voltage proportional to the phase difference between these pulses. A first sample-and-hold circuit samples the ramp voltage in response to a sampling pulse and holds the sampled voltage. To eliminate ripple component, a second sample-and-hold circuit is provided, which is also responsive to the sampling pulse for sampling a voltage from a constant voltage source and holding the sampled voltage. The voltages sampled by the first and second sample-and-hold circuits are input to a subtractor where the voltage difference between the two input voltages is detected. Ripple components generated by the two sample-and-hold circuits are cancelled out by the subtractor.

Abstract: A drive axle assembly and subassembly for use in tandem driving axle arrangements has a removable drive pinion shaft subassembly. An input shaft (14) is journalled in an axle housing (12) and is coupled to an output shaft (18) also journalled in the housing by an inter-axle differential (24) for torque sharing of driveline power. An input gear (28) receives power from the inter-axle differential and drives a countershaft gear (32) mounted on the drive pinion shaft (30). The drive pinion shaft is journalled in primary (44) and secondary (50) bearings which straddle the countershaft gear and are mounted on a removable cage (48) which substantially surrounds the countershaft gear. The drive pinion shaft with countershaft gear is assembled into the primary and secondary bearings on the cage and is shimmed (62, 64) between the bearings to form a pinion shaft and subassembly. A threaded nut (60) is torqued over the end of the drive primary shaft to retain and preload the drive pinion shaft in the bearings. The cage has a peripheral mounting flange (54) which permits the subassembly to be shimmed and bolted against the axle housing to locate the drive pinion on the axle ring gear. Upon installation of the subassembly into the axlehousing, a drive pinion pilot shaft portion (36) is journalled in a third bearing (38) in the axle housing.

Title: Compositions for supplementing and completing cement and method of using same
Inventor: CHARNOE ZEERA P
IPC: C04B41/52
Filed: 1993-06-30
Abstract: ABSTRACT           Compositions of soluble alkali metal silicates with selected surfactants exhibiting high detergency, low-foaming and superior wetting abilities are disclosed for use as concrete supplementation and completion agents. Treatment of cementitious materials with such agents has been found to increase their density and strength, and decrease their porosity, by penetrating deeply into the porous matrix of hardened substrates and augmenting the silicate polymer strands in the substrate.  Application of such agents to concrete forms or structures by applying a fine, even spray of the agent to the surface of the con-crete, is used for waterproofing the forms and structures and to drive out deleterious foreign matter such as salt from the pores of the concrete matrix.

Title: Produce packaging and methods of sealing same
Inventor: BROWN RICHARD S
IPC: B65D33/20
Filed: 1993-07-16
Abstract: ABSTRACT OF THE DISCLOSURE    An environmentally sealed packaging system for the storage and transport of vegetables which relies upon one or more plastic bags and which may be contained in suitable paperboard containers.  The plastic bags are usually of a large size and have a substantial thickness  in order to withstand the rigors  of transport and storage.   Nevertheless,  they are flexible and foldable.   When produce, and particularly vegetables such as lettuce, is stored in the plastic bags, the upper ends are sealed by engaging two opposed outer side walls and rolling the two outer side walls together to form an enlarged roll.   The ends of the roll are then folded inwardly and secured to the top in order to seal the opposite transverse ends.  The rolling of the bags effectively seals the two sides together and with the folding of the ends the interior of the bag is then sealed.   A releasable tape is then secured to the folded-in ends and to the roll in order to thereby hold the bag in a closed condition.  When it is desired to reopen the bags, it is only necessary to peel the tape from the plastic bags.  Various modes of tape placement are disclosed.

Inventor: DE BRUIJN THEO J W
IPC: C01B3/16
Filed: 1993-08-06
Abstract: Several procedures are provided for reducing the viscosity and density of a water emulsion, or a water mixture, of a specified feedstock, e.g., tar sand bitumen, heavy oil, refinery residue or any heavy waste oil stream to make them amenable for transportation by pipeline from the field to refineries for further processing. The feedstock also contains a naturally-occurring, finely-divided mineral material The thermal rearrangement of such materials includes contacting that water emulsion or that water mixture with synthesis gas or carbon monoxide in the presence of a catalytic amount of a bifunctional catalyst that facilitates the water gas shift reaction and also promotes the hydrogenation and stabilization of cracking reaction products. The bifunctional catalyst includes that naturally-occurring, finely-divided mineral material which is already contained in the feedstock. The process is conducted under such conditions of pressure and temperature that a water gas shift reaction occurs. Thermally rearranged liquid oil having a lower viscosity and a lower density than that of the feedstock is recovered. Separate streams of gaseous carbon dioxide and gaseous hydrogen are also recovered therefrom.

Abstract: SUMMARY      Cable lubricating equipment in the form of spray pipes 1.3/1.4, which are arranged in fork-shape around lift cables 3, with  spray nozzles 1.5/1.10 directed onto the lift cables 3.  The spray fork 1 is fastened on two supports 6 and 7 by means of pipe clips 8 and 9.  The supports 6 and 7 have distributing rollers 4 and 5, which are slidable in  slots  7.1/7.2  (6.1/6.2),  with  soft  surfaces  4.2/5.2.    The distributing rollers 4 and 5, which co-run with the lift cables 3 running  through,  embrace  the  lift  cables  3  almost completely and distribute the sprayed-on lubricant over the entire circumference of the lift cables 3.  The feed of the lubricant is effected by means of a  hose,  which  is  connected  to  the  connecting  stub  pipe,  from  a conventional garden pressure sprayer or from any container by means of a motor-driven pump.  With only one half of the lubricating equipment, thus  only one  spray pipe  1.4  and  one distributing roller 4,  any linearly moving or rotating machine parts could be lubricated.

Title: Culture vessel for cell cultures
Inventor: FALKENBERG FRANK W
IPC: C12M1/24
Filed: 1993-09-02
Abstract: Abstract There is a known culture vessel, similar to a roller bottle, for cell cultures which, forming a supply chamber, contains a nutrient medium in which is arranged at least one production chamber which receives the cell cultures and is bathed by the nutrient medium, and is separated from the nutrient medium by a dialysis membrane through which nutrients are transported from the supply chamber into the production chamber, and with a gas feed and discharge system into the supply chamber. In order to make available, on this basis, a culture vessel for generating cell cultures with a high cell density which is economical to manufacture and easy to handle, and in which the danger of infections is diminished, it is proposed that there be provided as a gas feed and discharge system for the gases required and produced during cell culturinq a gas exchange membrane that forms at least a part of the outer wall of the culture vessel and whose total surface area, material, and thickness are selected so that the permeability to oxygen is at least 0.01 mg/h for each 107 cells. Also known are methods for cell culturing wherein a nutrient medium that bathes a production chamber that is sealed on all sides and contains the cell culture being cultured is placed in a culture vessel and a continuous rolling motion is imparted to the culture vessel. In order to indicate, on this basis, a method that is easy to implement and with which high cell densities with concurrently high vitality can be generated in a short time, the production chamber is filled with the cell culture being cultured in such a way that it contains an air bubble whose volume occupies 10% of the volume of the production chamber, and a tumbling movement of the culture vessel is superimposed on the rolling movement in such a way that the air bubble moves in the cell culture.
