Abstract: Abstract of the Disclosure The device is primarily adapted for use in hospitals and comprises a housing having a front window through which a digital display of sensed temperature is observed.  The housing may receive one of preferably two probe holsters, one of which has associated therewith a probe for oral use and the other of which has a probe for rectal use.  Each probe holster is elongated in shape and has a passage for receiving a probe with the probe being fixedly wired into the holster so that the probe cannot be swapped between holsters.  The holsters and associated probes are constructed to be autoclavable and gas steriliz-able.  The probe is of improved design and employs a thermistor sensor.  The probe construction provides improved response time in sensing temperatures.

Abstract: Abstract of the Disclosure A print wire solenoid for high-speed operation is made with two major components or subassemblies.  The first is a plastic injected unitary bobbin or stator assembly which incorporates a core ring and a core, and a stator which forms a bobbin for receiving an electric coil.  The parts in the stator are positioned and molded to a datum surface.  The second major subcomponent is a unitary armature assembly which incorporates an armature, a retraction spring, and a print wire, all anchored to a plastic body.  These parts are likewise positioned with respect to a datum surface.  The stator assembly and armature assembly are retained within a drawn metal case, and a rebound disc is positioned within the case and locates the datum surface of the armature assembly in the same plane as the datum surface of the stator assembly so as to define an accurate working air gap.

Title: Method of manufacturing a device in a  silicon wafer

Abstract: ABSTRACT         A silicon body of a first conductivity type is covered with a sandwich of silicon dioxide, polycrystalline silicon and silicon nitride.  Source, drain, and inter-connect work sites of the body are exposed by a first photoshaping operation.  The work sites are doped forming regions of a second conductivity type.  Silicon dioxide is grown over the work sites.  A second photoshaping operation provides an opening.  The walls of the opening on two opposite sides comprise sides of the sandwich layer as established by the first photoshaping operation and the two remaining walls comprise sides of the silicon dioxide as established by the second photoshaping operation. Silicon nitride is next deposited over the entire wafer which is then photoshaped to define the field regions. The etching process is continued to remove part of the silicon body as well as the sides of those exposed regions. Thereafter, silicon dioxide is grown in the field regions. The remaining silicon nitride layer is removed to reveal the underlying conductive polycrystalline silicon at the gate region, the walls of the contact opening and the interconnect region.  A conductive material is deposited over the wafer and then photoshaped to provide the desired pattern of ohmic interconnections.

Abstract: INTRUSION DETECTOR FOR PRESS BRAKE                     ABSTRACT       An intrusion detection system is disclosed for safeguarding an operator of an industrial machine such as a press brake.  A light screen barrier (420) comprises sequentially pulsed beams (422) which are spaced far enough apart to permit penetration by a work piece (144) without obstructing more than one beam whereas penetration by the operator's hand will obstruct at least two adjacent, successively pulsed beams.  A pulse train of regularly spaced signal pulses (BRS) with each pulse corresponding to a light beam is produced when none of the light beams are obstructed.  A missing pulse detector (600, 40') with a logic circuit (502) produces a control signal for stop-ping the machine only when two or more adjacent light beams are obstructed causing two or more successive miss-ing pulses in the pulse train.

Abstract: PHN. 9523                    12 ABSTRACT:         In a method of manufacturing a disc-shaped plastics record carrier having a laminated structure, a quantity of moulding resin in liquid form is deposited in a central cavity in a mould surface which is formed with an information track or tracks of spiral or circular form.  A flexible plastics substrate which has a central boss with shape complementary to that of the cavity in the mould surface, and which has been deflected into a spherosymmetrically domed shape with its convex side facing the moulding resin, is then pressed against the resin and flattened so that the resin is rolled out over the mould surface.  The moulding resin is subsequently cured and the assembly thereto is removed from the mould.  By initially depositing the moulding resin in a central cavity in the mould surface, the formation of air bubbles in the resin due to the resin being pulled towards the approaching substrate by static electricity in the substrate is inhibited.  In an alternative embodiment the liquid mould-ing resin is initially deposited in a central cavity in a rigidly supported plastics substrate, and a flexible mould plate having a mould surface which is formed with the information track or tracks and with a central boss is deflected into a spherosymmetrically domed shape and pressed against the moulding resin.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel ball-and-socket-type pipe coupling is provided herein for interconnecting a first pipe with a second pipe.  It includes a first socket housing fixedly mounted to an end of the first pipe; a second socket housing fixedly mounted to an end of the second pipe; each of the first and second socket housings having a spherical concave surface formed internally thereof; a single piece of joint pipe of simple cylin-drical construction having opposite free end sections; one of the free end sections extending into the first socket housing and the other of the free end sections extending into the second socket housing; a first ball member including an annular member mounted on the one of the free end sections and having a spherical outer surface disposed in spherically sliding contact with the concave surface of the first socket housing; and a second ball member including an annular member mounted on the other of the free end sections and having a spherical outer surface disposed in spheri-cally sliding contact with the concave surface of the second socket hous-ing. The joint pipe is angularly movable in accordance with spherical sliding movement of the first and second ball members with respect to the housing, while maintaining parallel relationship between the first and second pipes.  Each of the first and second ball members includes a front end section including an annular projection extending radially in-wardly and having a first internal annular wall, a rear end section which is formed with an annular extension extending radially inwardly and having a second internal annular wall, and an annular hollow space ex-tending between the first and second internal annular walls.  A first stop member is fixedly mounted on the one of the free end sections of the joint pipe and is disposed within the annular hollow space of the first ball center.  A second stop member is fixedly mounted on the other of the free end sections of the joint pipe and is disposed within the annular hollow space of the second ball member, preferably also in its center.          The joint pipe is telescopically slidable in its axial directions with  respect to the first and second ball members within a limited range.          The coupling is particularly advantageous when utilized in places where it is necessary to connect a pair of parallel pipe lines lying on two different planes or it is expected that a pair of connected pipe lines might be subjected to dislocation by an earthquake, subsiding of ground, or considerable weight, shocks or vibrations.  The pipe coupling is also very useful in repairing such pipe lines that have been misaligned or actually affected by dislocation or subsiding of ground.
