Title: Universal joint for transmitting torque from one  shaft to another
Inventor: WEIBLE WARREN W
IPC: F16D3/10
Filed: 1980-02-20
Granted: 1982-08-31
Abstract: ABSTRACT OF THE DISCLOSURE       A universal joint is provided and particularly a universal joint of the constant velocity type. The joint is particularly intended for use in drive trains of front wheel drive vehicles. The universal joint includes a pair of mem-bers attachable to each of two shafts to be joined, with a curved elongate bridging element connecting the two members. The bridging element extends in a curve from 180° up to sev-eral turns in progressing from one of the members to the other. The bridging element is designed to have high resis-tance to bending in both a direction parallel to and a direc-tion perpendicular to axes of the two connected shafts, when they are aligned. At the same time, the bridging element is designed to have low resistance in torsion or to twisting. These characteristics enable the bridging element to transmit torque from one shaft to the other and yet enable the bridging element to twist or flex so as to accommodate angular misalign-ment between the two shafts. In a preferred form, the bridging element is of I-shape in transverse cross section and is made of a multiplicity of graphite fibers extending longitudinally thereof and held in a structurally integral shape by means of a binder or coating material, such as a resin.

Abstract: ABSTRACT OF THE DISCLOSURE         A superheterodyne type multiplex signal receiver for multiplex signal transmission systems for receiving two in-dependent signals transmitted by amplitude modulation and angle modulation of single carriers, and for detecting an intermediate frequency by an intermediate frequency detector when changing the local oscillating frequency by a dial op-eration to select the received signal.  The receiver has a switching circuit so composed that it operates a demodulation circuit which demodulates, from the modulated carrier, the two independent signals, which are then transmitted to two independent audio amplifiers provided at a later stage of an intermediate frequency amplifier for driving two speakers for reception of the multiplex signal, when the intermediate fre-quency is extremely close to a normally determined frequency.          The switching circuit also transmits  to the two independent audio amplifiers the demodulated signals obtained from an envelope detection circuit when the intermediate frequency is remote from the normally determined frequency.

Abstract: ABSTRACT D-20,961 A disk-shaped flashlamp unit for use within an indexing means or mechanism associated with a camera. The unit includes several, e.g. ten, electrically-activated flashlamps radially disposed within the unit's plastic, light-transmitting housing. A pair of planar reflectors are utilized for each lamp to reflect the light therefrom through the housing. Light output can be further enhanced by utilization of two additional planar reflective members adjacent each lamp, the four members surrounding the side and bottom portions of the flashlamp's envelope to thereby direct light emitted from the flashlamp in a substantially singular direction through the peripheral region of the plastic housing. The invention's reflectors also assure prevention of sympathetic ignition.

Abstract: Abstract of the Disclosure An accumulating conveyor comprising a frame on which a plurality of horizontally spaced-apart power rollers are positioned for propelling articles along the conveyor.  Each power roller includes a tubular metal roller member terminating at opposite ends and having an axial passageway extending between and through its opposite ends.  A motor driven drive shaft which is mounted on the frame extends through the roller member's passageway and supports a friction drive member formed of powdered metal and impregnated with a lubricant.  The fric-tion drive member is positioned in the passageway in frictional engagement with the roller member and rotates conjointly with the drive shaft.  Rotation of the drive shaft is transmitted by the friction drive member to propel the articles along the conveyor.  When the movement of the article is restrained, the friction drive member slips in the passageway relative to the roller member so that the roller member remains motionless.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for the control of power consumption in individual space-conditioning loads fed by an electric power network utilizes a commandable, programmable temperature control device which gradually, substantially continually changes the control setpoint in response to an external signal to reduce power consumption such that tem-perature changes go relatively unnoticed by the occupants.          A radio receiver or the like is utilized to receive a signal from the power utility company and, in response to the sig-nal, the setpoint function of the thermostat associated with the load becomes an electronically simulated function in accordance with the invention and the user-control setpoint is removed from the control loop.  The effective load shedding is also greatly enhanced by the provision of an integral reset function in addition to the conventional pro-portional control within the temperature control system.          The use of a plurality of such systems enables the power utility to control electric power network peak load with a minimum impact on the comfort of individuals in the conditioned spaces.         In the cooling mode, the temperature setpoint is caused to be slowly raised or ramped in a substantially con tinuous manner to a predetermined maximum temperature during the peak power consumption hours and, thereafter, is ramped back down to the fixed rate until the conditioned space is returned to its original temperature at which point control is returned to the user.  Conversely, in the heating mode, the setpoint is ramped downward to a predetermined minimum temperature limit during peak power consumption hours and, thereafter, ramped back upward to its original setpoint at which time control is also returned to the user.

Various materials are recommended for use as the sintering agent, and in particular the boric acid.  The proposed refractory powder is produced as follows: the aluminium oxide and silicon dioxide powders are first heated to a temperature of from 1200°C to 1400°C and from 900°C to 1200°C respectively, whereafter said powders are cooled to room temperature, and then mixed with adding the sintering agent to produce a uniform mixture.  The specification of the invention discloses various modifications of the method of producing the refractory powder of the invention.  The proposed powder is capable of preventing a corundum light transmitting member of the light transmitting device mounted in the lining of a metallurgical vessel for transmitting thermal gradiation from a melt to a pyrometer, from being damaged during the operation of said metallurgical vessel.
