Abstract: ABSTRACT:                  A wound capacitor comprising a cylindrical housing which includes an expansion space which is closed on the one side by a lid and which is bounded on the other side by a rigidly arranged centring disc which is provided with openings. Via the openings, the expansion space is in open communication with a space in which a capacitor roll, disposed on a cylin-drical core, is arranged. Connection wires are connected to the electrodes in the capacitor roll. These wires are anchored in the lid as well as in a centring member arranged in the centring disc. The centring member is locked against axial displacement by way of a shoulder which bears against the centring disc. In the case of an inadmissibly high gas pressure in the capacitor, the lid is displaced relative to the centring member and the connection wires are broken, the capacitor thus being rendered explosion-proof.

Abstract: ERROR CHECKING AND CORRECTING DEVICE            Abstract of the Disclosure An error checking and correcting device for providing group error detection in addition to single error correction and double error detection in a codeword transmitted through a modular communication channel is disclosed.  The codeword comprises a plurality of data bits and a plurality of check bits.  The modular communication channel comprises a plurality of modules in each of which a group (or cluster) of bits are transferred in parallel.          In the preferred embodiment, the code word contains 40 bits with 32 data bits and 8 check bits, and the modular communication channel is a computer memory comprising 10 modules with 4 bits per module.  At the transmitter, the check bit generator generates the check bits from the data bits in accordance with an H-matrix which is partitioned into h-submatrices corresponding to group boundaries of the memory.  The construction of the h-submatrices is in accordance with rules necessary for group error detection in addition to single error correction and double error detection. the check bits are appended to the data bits to form a 40 bit code word which is transmitted through the modular memory.  At the receiver, a syndrome bit generator generates 8 syndrome bits from the received code word in accordance with the H-matrix.  The output of the syndrome bit generator is coupled to both the error detection circuit and the error location circuit.  Should a group in the memory be faulty in the process of transmission resulting in a number of bits in the group being in error, logic means are provided in the error detection circuit to identify correctable good data from uncorrectable bad data.  According to the syndrome pattern the error detection circuit permits the utilization of re-ceived data if no error is detected, or enables the error location circuit to provide single error correction if a single error is de-tected; or sets an error flag to prohibit the utilization of receive?

Abstract: ABSTRACT OF THE DISCLOSURE A compact, rigid camera has a folded optical path between an object-ive lens and a film plane and formed at least in part with a prism element having an entrance face, an exit face overlying and closely spaced from the film plane, and a reflective face.  The exit face both reflects light which enters the prism at the entrance face and transmits light out of the prism. The reflective face is inclined to return to the exit face, for transmission to the film plane, the entering light internally reflected at the exit face. The entrance face of the prism is inclined relative to the reflective/trans-missive face by an angle larger than the relative inclination of the re-flective face.  Light transmitting prism surfaces, spacings between optical elements, light absorptive coatings, and mechanical light controlling elements including a light collimator, prevent the entry of unwanted non-functional light into the prism and eliminate such light that does enter the prism.  In a preferred form, the prism is of a transparent, low dis-persion plastic material, and the exit face is at least coextensive with the film plane.

Abstract: ABSTRACT OF THE DISCLOSURE             An operating device for an electric circuit breaker comprises a closing spring and a rotatable spring-controller mounted for rotation between first and second dead-center positions with respect to the spring. The spring is charged by transmitting rotational forces to the spring-controller through a main pawl mounted on the spring-controller and an abutment on a rotatable driving member. The main pawl is released from driven engagement with the abutment at the end of a spring-charging operation. Normal circuit-breaker closing is affected by allowing the spring to quickly discharge after a charging operation.            A manual slow-close operation of the circuit breaker is effected through an auxiliary pawl mounted on the spring-controller in a position angularly-spaced from the main pawl.  During normal spring-charging and discharging operations, this auxiliary pawl is  prevented from engaging the abutment on the driving member.  But when a manual slow-close operation is to be effected, engagement between the auxiliary pawl and the abutment is allowed.  Rotation of the driving member during such engagement rotates the spring-controller through a slow-close operation. This slow-close operation is affected without assistance from the closing spring since prior to the manual slow-close operation, the closing spring is disabled while in its charged condition and held disabled during the slow-close operation.

Abstract: ABSTRACT OF THE DISCLOSURE     That is to say, in a process that involves use of a fluidized bed of solid particulate material wherein. fluidization is obtained by passage of a gas through the bed, and the bed is stabilized by including discrete magnetizable particles in the bed and applying a substantially uniform magnetic field to the bed, temperature gradients that occur in the bed when the process in which the fluidized bed is used involves release or absorption of heat are reduced by periodically removing the magnetic field in a cyclical fashion.  The period of magnetic field removal is long enough to destabilize the fluidized bed with respect to the positioning of fluidized particles so that the particles will move about in the bed, but the period of removal is not so long as to permit the un-stabilized bed to exhibit a boiling or bubbling effect.  The ratio of "on" time to "off" time is generally within the range of from about 4 to  1 to about 4000 to 1.

Abstract: ABSTRACT     A controlled space is maintained at a desired set point temperature by adjusting the refrigerant temperature at the evaporator outlet in a refrigeration system, thereby controlling the evaporator effectiveness or capacity which is inversely proportional to the outlet temperature.  When the space temperature tends to vary from the desired set point due to a changing heat load, the control system automatically changes the refrigerant flow through the evaporator to establish the evaporator outlet temperature at the control point required to maintain the controlled space at the desired temperature.  More specifically, in response to a space temperature increase, the flow rate of the refrigerant increases; and in response to a drop below the set point, the refrigerant flow decreases.  Such control of the flow rate is achieved by varying the actuation of an electromechanical valve, such as a solenoid valve, interposed between the condenser and evaporator in the refrigeration system, the valve also serving as the system's expansion device.  When the heat load on the evaporator is constant, the refrigerant flow is controlled in order to hold the evaporator outlet temperature fixed at the required control point.
