Title: Cord carrying device for an automobile
Inventor: KOZAKEVICH BERNARD
IPC: B60R9/06
Filed: 1990-06-07
Abstract: Abstract In cold climates it is common for automobiles to be equipped with block heaters so that they can be more easily started after they have been parked for some time, e.g. overnight, in sub-zero temperatures.  The block heaters generally have a short electrical cord which must be connected to an extension cord which, in turn, is connected to an electrical outlet.  If the extension cord is left outside when not in use it can be buried in snow or stolen.  To overcome these problems, the present invention provides a device for carrying an extension cord (or a long cord on the block heater) with the automobile.  The device is inexpensive and stores the cord in a convenient location for use, namely on the front bumper of the automobile.  A preferred embodiment comprises a box having a base member with an open-topped-box shaped cover member hingedly attached to it.  One of the members has hooks or a spool attached to it for carrying a cord.  The device attaches to the front bumper and a licence plate can be attached to the device.

Title: Damped binding apparatus
Inventor: SCHENK RICHARD C
IPC: G03G15/00
Filed: 1990-07-23
Abstract: An apparatus which adhesively binds a set of sheets by applying a strip having an adhesive on one surface thereof to the spine of the set.  The strip is supported on a heated platen which softens the adhesive.  The spine of the set of copy sheets is pressed into the adhesive on the strip.  The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness.  As the spine of the set of copy sheets is moved into contact with the adhesive on the strip, it is damped to absorb a substantial portion of the kinetic energy of the set of sheets to reduce the deflection and distortion of the set of sheets.

Title: Packets and packaging
Inventor: VERNON GEOFFREY W
IPC: B65D85/808
Filed: 1991-03-20
Abstract: Twin compartment packets, eg. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continuously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.

Abstract: Abstract Of The Disclosure A method and apparatus for determining flow rates of well fluid constituents on a much smaller scale than with prior art equipment.   Rather than testing the total fluid stream, a sample stream portion is diverted from the total fluid stream and tested.  The sample fluid stream portion is separated into its various constituents,  and the mass flow rate of each constituent is determined.  The total mass flow rate of the total fluid stream is measured and compared with the total mass flow rate of fluid flowing through the sample stream portion, so the total flow rate of each constituent may be calculated.
