Abstract: PCT No. PCT/SE85/00006 Sec. 371 Date Sep. 10, 1985 Sec. 102(e) Date Sep. 10, 1985 PCT Filed Jan. 9, 1985 PCT Pub. No. WO85/02990 PCT Pub. Date Jul. 18, 1985.Sitting bathtub constituted by a tub (10) provided with an opening (11) extending almost down to the bottom of the tub and a hatch (15) to close this opening. When closing the bathtub before having a bath the hatch (15) is placed on the inside of the bathtub and the hydrostatic forces of the water forces the hatch against the edges of the opening where a seal is provided on the hatch. The sides and in particular the side with the opening are inclined or sloped outwards from the bottom so that the hatch with its seal will rest by its own weight against the seal. In particular seal (16), hatch (15) and the side of the bathtub are so arranged that a good sealing effect is always certain at the bottom of the bathtub when the rising water and the resulting hydrostatic pressure enable the sealing effect to climb upwards even on a light and slightly flexible hatch. This in turn enables the hatch to be very light and easy to handle and it is thus no inconvenience to have a loose hatch. The hatch is suitably transparent or clear.

Abstract: A power cylinder of a hydraulic percussion implement, in whose bore a ram with an enlarged piston head is vertically reciprocable to strike a tool at the lower end of the bore, has a control chamber above the piston head alternately communicating with the high-pressure side and the low-pressure side of a source of hydraulic fluid, an annular recess in the bore being permanently or intermittently connected to high pressure acting upon the underside of the piston head. An annular drainage chamber formed by the bore at a lower level, disposed above an oil seal, collects liquid leaking down from that recess and returns it to the source. A pneumatic buffer lies in or communicates with that drainage chamber for absorbing hydraulic shocks generated when the ram strikes the tool.

Title: Arrangement for providing a call-connection service
Inventor: BICKNELL RAINIE MARIE
IPC: H04L12/56
Filed: 1990-01-30
Granted: 1996-06-25
Abstract: In a private communication network served by a provider of call interconnection services, e.g., a carrier service node, the number of trunks used within a call path is reduced without affecting the private nature of the private network. The service provider serves customer calls by means of a service node controller (SNC) --a switch such as a PBX. The SNC directly interconnects trunks that connect it with a call-source and a call-destination node of the customer, without routing the call through the customer's tandem node. The SNC merely queries the customer's tandemnode over a control link, such as an ISDN D channel, to obtain requisite call-routing information from the customer's database. The customer retains ownership and control of the tandem node and its database, thereby preserving the private nature of the private network.

Title: Frequency control based on sensing voltage fed to an induction motor
Inventor: KERKMAN RUSSEL J
IPC: H02P21/06
Filed: 1990-05-17
Granted: 1996-03-12
Abstract: A frequency control method is incorporated in a motor drive to prevent overcurrent trips when an induction motor is subjected to impact loads or reconnection under load.  The drive includes a current regulator loop to control stator current and a voltage regulator loop to control the command to the current regulator.  Motor voltage is sensed and a voltage error is developed.  This voltage error is processed through a proportional-integral control loop which controls an operating frequency signal to the current regulator.  The drive responds during current limit conditions to reduce operating frequency and speed until the current limit conditions subside.  The motor can then be re-accelerated up to the desired operating speed.

Abstract: LOCAL AREA NETWORK ARCHITECTURE Abstract A network ring topology includes a plurality of entry and exit interfaces (100,110) disposed in administrative locations such as in an equipment room (53) and in riser and satellite closets (51, 57), and at stations. Interconnections between ports of sets of ports of the interfaces are made in the closets by jumpers (120-120) and either in a direct or in all inverted manner, the direct being between corresponding ports of corresponding sets of ports in interfaces. Inverted connections are made between two exit or between two entry interfaces in which input and output ports of corresponding rings are connected by jumpers. The interfaces are color coded and may be either entry or exit type to denote the arrangement of the ports. The interfaces and the color coding arrangement allow a craftsperson to make connections in an administrative location without having to follow signals through the ring. For a dual ring counter rotating network, each interface necessarily includes two sets of ports.

Title: Magnesium oxide coating for electrical steels and a method of coating
Inventor: MURPHY ROBIN A
IPC: C21D8/12
Filed: 1990-08-29
Granted: 2000-02-15
Abstract: Decarburized grain oriented silicon steel is provided with an annealing separator which forms a glass film after the final high temperature anneal.  The magnesia used as the annealing separator has a total chlorine level of 0.01 to 0.20% by weight based on the weight of magnesia with at least 0.01 % metal chloride selected from the group of Mg, Ca, Na and K. The chloride addition acts to seal the coating surface during the final anneal to control diffusion and stabilize the secondary grain growth. The glass film which forms during the anneal may be laser scribed for domain refinement without coating damage. The magnesia may also contain additions of phosphates, TiO2, SiO2, Cr and B. The temperature of the magnesia is maintained below 25°C to control hydration and eliminate the need for other additives in the magnesia slurry to control hydration.

Title: Inflatable tool
Inventor: CORONADO MARTIN P
IPC: E21B33/127
Filed: 1990-10-16
Granted: 2003-03-25
Abstract: An inflatable well tool and method of use is provided.      The tool has a central body and an annular inflatable packing element. A fluid passageway transmits pressured fluid for inflation purposes. One end of the packing element is secured relative to the tubular body while the other end is selectively secured relative to such body. The inflatable means is posi-tioned such that a pre-determined amount of axial tension must be produced in the inflatable element prior to releasing one end of the element for axial movement relative to the tubular body to provide a more uniform radial inflation of the inflata-ble element. The device may be repeatably utilized without retrieval to the top of the well and the inflatable element is biased to permit second inflation by resisting axial movement of the inflatable element relative to the tubular body such that second and subsequent settings of the tool in the well result in uniform inflation of the inflatable element.

Abstract: The present invention is concerned with a stable edible dispersion comprising 95 to 86% by weight of an aqueous phase and 5 to 14% by weight of a continuous fat phase having and N20-value of at least 5.            It is surprising that, provided suitable processing conditions are applied and a seeding component is employed, stable dispersions containing less than 14% by weight of a continuous fat phase having an N20-value of at least 5, and more than 86% by weight of an aqueous phase can be prepared.            Another aspect of the present invention is a method of preparing a dispersion comprising 95 to 86% of an aqueous phase and 5 to 14% by weight of a continuous fat phase having an N20-value of at least 5, said method comprising cooling and working an emulsion of oil and water, the oil comprising 0.1-4%, by weight of the oil, of a solid seeding component.

Granted: 1997-05-20
Abstract: Described are new strains of Drechslera spp., which possess herbicidal effects against all varieties of barnyard grass, i.e., Echinochloa spp. as weed but do not give any influence to crops under cultivation such as rice.  Weed control agents according to the present in-vention, which contain one or more of the novel strains, have high safety and selectivity, thereby providing practical control effects against barnyard grass.  Weed control compositions according to the present invention, which contain one or more of the new strains in combination with one or more chemical her-bicides, have sufficient herbicidal effects even at dosages which are too low to permit control of weeds when they are applied singly, thereby making it pos-sible to reduce the dosage of herbicides.  The weed control compositions can therefore contribute to the prevention of environmental pollution and the occur-rence of weeds with acquired pesticide resistance.
