Abstract: A sealing ring for sealing the space between two substantially coaxial sealing surfaces which are axially insertable one in the other to a jointed position, especially for sealing the annular space between socket and spigot end of a pipe joint, comprises a first sealing portion (2) and a second sealing portion (4). The sealing portions are adapted at the axial insertion movement substantially stationary to engage one surface each of said sealing surfaces and to slide against each other. The first and the second sealing portion are by means of a releasable and/or substantially expensible connector portion (6) connected with each other at least at the front side of the sealing ring in respect of the direction of insertion movement of the second sealing surface during the jointing of the sealing surfaces.

Abstract: The present invention is a vertically upright hermetic compressor for mounting to a horizontal support surface in an appliance. It comprises a housing with a bottom end, a motor compressor unit operably disposed within the housing, and a resilient boot attached to the housing bottom end to suppress noise and vibration emitted from the compressor. A mounting plate supports the boot for mounting the compressor to the horizontal support surface. The plate receives the boot in a central aperture and has grommets for spacing the boot above the surface and attaching it to the horizontal support surface.

Abstract: A load control system and tool arrangements are disclosed for controlling the shutheight and back-up load on a mechanical press tool in response to a monitored or measured parameter indicative of press tool force or part quality, which monitored parameter is communicated to a controller for determination of a control signal to control a means for regulating the press tool back-up load and shutheight without interrupting press operations. The control system is operable to control a single station or multi station press and can be installed on either an individual press tool or the bolster or slide.

Abstract: The disclosure relates to double ended tube coupling (10) having a coupling body (11) with the throughway (12) through which a tube can pass. Collets (16) are located in the open ends of the throughway having resilient arms to engage the tube and tapered internal cam surface (15) are formed adjacent the open ends of the throughway to engage the arms of the collets to cause the collet to lock tubes extending into the ends of the coupling body in the body. Midway along the throughway in the coupling body there are four resilient arms (25) moulded integrally with the wall of the coupling body and inclined towards one end of the coupling body to provide end stops (26) to limit the insertion of a tube into the coupling body from that one end but to permit a tube to pass through the coupling body when inserted from the other.

Abstract: A fuel monitor assembly for use in testing the contamination level of a fuel sample is disclosed, including a housing having a fuel inlet and a fuel outlet, and a fuel filter capsule disposed within the housing. The filter capsule includes an inlet half and an outlet half, wherein the halves interfit to retain a membrane filter therebetween. The inlet half of the filter capsule is integrally formed with an inlet dispersion structure that radially disperses an incoming stream of fuel so as to equalize the pressure across the face of the membrane filter, thereby resulting in even distribution of contaminant particulates deposited on the membrane filter. The outlet half of the filter capsule is integrally formed with a recessed, radially symmetric grid configuration that channels fuel passing through the membrane filter to the fuel outlet, and also encourages equal pressure distribution across the face of the membrane filter.

Abstract: According to the invention, a safety coupling, the torque transmission of which takes place as a result of the radial tension of a clamping sleeve which is under high pressure, has a release valve. During a rotation of the shaft relative to the hub, caused by overloading, the release valve is opened, so that the torque transmission is interrupted as a result of a reduction of the pressure in the clamping sleeve. After rotation, the tappet of the release valve is drawn into the release valve, so that the safety coupling can be put into operation again as a result of a pressure buildup, without any destruction or wear occurring.

A bore in the hub includes transverse ribs for engaging with an annular groove in the driving shaft of an electric motor. A flat surface is formed inside the bore for engaging with the corresponding flat surface on the driving shaft of an electric motor. A resilient expandable split metal sleeve engages the exterior surface of the hub.

Abstract: The present invention is a diagnosis and testing system for a temperature control system which includes a communication bus, a control processor, and a service thermostat. The communication bus is coupled to substantially all of the components of the system. The control processor initiates communication between components by sending a bus address over the bus. The control processor includes an address decoder for recognizing various bus address signals, including a normal thermostat bus address and a service thermostat bus address. The service thermostat has a switch, a processor, and a bus interface unit. The switch selects the operating mode of the service thermostat, e.g. either normal or service modes. The bus interface unit communicates over the bus for the service thermostat processor. The service thermostat processor operates the service thermostat and is adapted to communicate over the bus using a bus address according to the operating mode which is determined by the switch.

Abstract: A pillow provided with a power unit for rotating its top surface about a horizontal center line of rotation into a new angular position whenever a snoring noise is detected. The angular position of the head of the sleeping person is thereby changed gradually enough not to wake him up but since his larynx is changed into a new state every time the top surface of the pillow is rotated into a new angular position the snoring noise is eventually controlled. Reliable detection of snoring noise is made possible by taking advantage of the periodic nature of the snoring noise.

Abstract: This invention pertains to a lamp socket assembly for use in automotive applications and the like. The assembly includes a housing, a contact insert, and a body. The contact insert is captured in the cavity of the housing by the body. The body is welded to the housing. Lugs on the body secure the assembly to a panel. A seal is placed between a flange on the housing and the panel to seal the assembly to the panel. Contacts are retained in the contact insert by engagement of U-shaped portions in slots of the contact inserts. Blade terminals are inserted through windows in the housing, contact insert, and contacts to interlock the terminals with the contacts and to keep the contacts secured in their positions. A socket connector is sealingly secured to the housing and prevents moisture from entering the housing. In an alternative embodiment, no socket connector is provided but the blade terminals are crimped to wires for connecting the socket assembly to a source of electric power.

Abstract: A speed control circuit in combination with an electrical motor for use in a hand-held food mixer operated on AC household electrical current. The motor is a universal type having a series connected armature winding and field winding wherein the field winding includes a plurality of taps each selectably connectable to the current source by a multipoint switch. A Quadrac.TM. semiconductor switch containing a triac and triggering diac in one package conducts electrical current from the current source through the armature winding and the selected portion of said field winding over a portion of each cycle of the current source. A trigger signal causes switching of the semiconductor switch at a predetermined phase angle relative to the voltage waveform of the current source. An error signal of a magnitude proportional to motor speed and based on counter EMF of the motor is generated by the entirety of the field winding.
