Patent DE-3070241-D1 (DE)
Title: Object and people counting system
Inventor: MOTTIER FRANCOIS M
IPC: G07C9/00
Filed: 1980-10-14
Granted: 1985-04-04
Abstract: The perimeter of an area is scanned along two adjacent paths which define spacially resolved gates through which objects and people must pass to enter and leave the area. As the gates are scanned, the presence of objects and people are detected. A complete scan produces a gate signature which includes information indicative of the presence and location of objects and people in each gate during the scan. Successive signatures are compared in sequence as scans are made in order to determine changes caused by movement of objects and people in or out of the area. From this comparison an up/down counter is controlled to maintain a dynamic count of the number of objects or people in the area following each scan of the gates. The counter counts up as objects and people enter the area and counts down as they leave.

Title: Method of producing plastics material containers
Inventor: WARD PETER
IPC: B29C49/16
Filed: 1982-10-14
Granted: 1986-09-04
Abstract: The invention discloses a method of forming plastics material containers from heated plastics sheet material (32) in a thermoforming apparatus, wherein sheet material (32) is first of all displaced away from the mould cavity (28) on to the surface of a chamber (38) opposite the mould cavity (28) using a very high pressure differential, in order to induce hoop orientation in the material, and then the displaced material is moved into the mould cavity (28) against the high pressure differential and finally is shaped to the shape of the mould cavity (28). By using a chamber (38) of predetermined shape and maintained at the orientation temperature, containers having a resonably predictable degree of orientation, at least in the top region thereof, can be produced. The invention discloses also that a plug (40) and clamp (45) are used to clamp the sheet material (32) and to pull it into the mould cavity (28) against the high pressure differential.

Title: Zeolite as a detergent aid
Inventor: GRESSER ROBERT
IPC: C11D3/12
Filed: 1983-06-09
Granted: 1986-10-02
Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.

Title: Applications of heat flux modulation of a temperature probe
Inventor: PHILLIPS STEPHEN R
IPC: G01K11/20
Filed: 1984-10-12
Granted: 1989-08-17
Abstract: To measure the heat transfer coefficient of a sample, an element with temperature sensitive optical properties is placed in contact or implanted in the sample. The element is heated or cooled. The temperature difference between the element and the unheated sample and the rate of heating or cooling indicate the heat transfer coefficient of the sample. In one embodiment, the element is heated or cooled at a constant rate. The heat transfer coefficient of the sample is then inversely related to the difference in temperature between the element and the unheated sample. Alternatively, the element may be heated or cooled at such a rate that the temperature difference between the element and the unheated sample remains substantially constant. The heat transfer coefficient of the sample then varies directly with the rate of heating or cooling. The heat transfer coefficient of a sample is a measure of its composition and other physical properties. The composition of gasses, liquids, the presence of bubbles in a liquid, and fluid levels can be detected by the optical technique. Pressure and flow rates of fluids can also be detected. The technique can be used also to more accurately measure the thermal conductivity and temperature of small objects with small heat capacities.

Title: Drilling tool, especially a drill bit
Inventor: HOLZL KURT DIPL ING
IPC: E21B10/60
Filed: 1985-06-14
Granted: 1988-07-14
Abstract: A drilling bit, such as a crenellated drilling bit for fluid-jet supported rotary drilling in rock comprises a nozzle for directing a jet of high-pressure fluid against rock material being bored. In addition to transporting away rock chips, the jet penetrates fissures in the rock and supports the breaking down of the rock structure by the drilling bit. Since such nozzles tend to wear more rapidly than the cutting edges of the drilling bit, a readily exchangeable nozzle insert is provided. The nozzle insert is seated in a retaining body incorporated in the drilling bit and is held in the retaining body by a threaded annular cap. The annular cap has a hexagonal recess for accommodating a tool such as an Allan-key.

Granted: 1990-11-15
Abstract: An apparatus for hardening cores and/or molds made of sand with the addition of hardenable binding agents, which are used for casting molded bodies from flowable substances, is described, whereby an amount, predetermined by metering devices controlled via control valves, of the substance which causes the binding agent to harden is introduced into the core or mold by aid of compressed air the rate of flow of which is regulatable by a regulating valve, whereby this substance is mixed with this compressed air, and the regulating valve is automatically controlled according to a predetermined schedule. The apparatus can be carried out with considerably fewer components and the necessary control means can in particular be designed much more simply if, according to one embodiment, the regulating valve is controlled by means of a proportional pressure regulating valve which is operated by an external control means which also controls the other control valves. As an alternative to this, the regulating valve can be controlled, according to a second embodiment, via a preadjustable pressure regulating valve and a directional valve which is controlled electrically or pneumatically.

Abstract: A device for withdrawing from a bar pusher and thereafter unloading the crop-ends of the metal bars in a bar feeding apparatus for a multi-spindle lathe, said device being suitable also for placing a new bar on said bar pusher, is disclosed.The device of the invention is comprised essentially of a pair of movable jaws which by means of a turning movement close onto the crop-end of a metal bar and lock said crop-end therebetween. Said crop-end is the residual part of the lathe machining of the metal bar.Thereafterthejaws accomplish a translation movement to detach the crop-end from a bar pusher which formerly caused the bar forwarding in the feeding apparatus of the lathe. The jaws thereafter open slowly dropping the crop-end in a proper unloading zone. Finally the jaws close onto a new metal bar to be machined and, by means of a further translation movement in the direction opposite to the former one, perform the insertion of the new metal bar end into the bar pusher.

Abstract: A mixture of virgin crumb rubber sized to between 30 mesh and 100 mesh containing less than 5%+100 fines and thermoplastic binder, such as carbon black filled polyethylene containing a coating promoter, such as a citrate salt and lubricant, such as a calcium stearate, is mixed in a vented Banburg mixer heated to at least 350 DEG  F. to remove volatiles through vent before extrusion. The mixture is formed into sheet in the nip of a two roll assembly and cooled in air before diced into pellets by a dicer. The pellets are formed into porous pipe by extrusion in a pipe extruder having the feeding, transition and metering zones separately heated to temperatures from 320 DEG  F. to 400 DEG  F. (T1, T2, T3). The die has a separate jacket receiving heat exchange fluid for heating the die to a temperature from 290 DEG F. to 380 DEG  F. to form a porous pipe having more uniformly spaced and sized pores and a smoother inner wall surface. The linearity factor, tensile strength and elongation are also improved.
