Title: Transistor electrical circuit with collector voltage stabilization
IPC: H03F1/30
Filed: 1968-08-26
Abstract: An output transistor 152, for example in an f.m. channel 10, is connectable to an unregulated supply 158 at a terminal 96, for example a supply for a valve 100, and to prevent the collector breakdown voltage of the transistor 152 being exceeded, the quiescent collector voltage is stabilized by feedback from the collector via a potential divider 160 162 (and resistors 164, 166) to the base circuit, the transistor 152, the divider 160, 162 and the terminal 96 all being in the same integrated circuit, 10. A second transistor 150 completes the base circuit. A f.m. signal at 16 is coupled to a tuned circuit 20 and to a terminal 12 of the circuit clip 10, which carries two amplifier stages 24, 26, 28 and 40, 42, 44, a limiter 56, 58, 60 and a discriminator 74. Voltage supplies to the transistors 24, 26, 28, 40 and 42 are derived from a transistor 112, and to the transistors 44, 56, 58 from a transistor 114, the transistors 112, 114 having their collectors connected to a positive supply terminal 104, and their base potentials regulated by the emitter-base breakdown voltage of a transistor 108 connected to the positive terminal 104 and to an earth terminal 106. Transistors 116, 118 are reciprocably coupled to produce a stable bias voltage for the stages. External to the clip are the discriminator drive transformer 68, and the volume control circuit 88, &c. as well as decoupling capacitors 130, 138, the tuned input circuit, and the output resistor 156 and capacitor 98.

Title: Boiler having tapered duct elements
IPC: F24H1/32
Filed: 1969-01-24
Abstract: A sectional boiler comprises elements in aligned abutting relationship, each pair of adjacent elements defining therebetween a number of tapering ducts provided with fins integral therewith and at an oblique angle to the longitudinal axis thereof. The sectional boiler comprises intermediate elements 100, Fig. 6, formed with channels 101 on one face, and similar channels 102, Fig. 7, on the opposite face. End elements (not shown) are provided with channels on one face only. When the elements are connected together, adjoining channels 101, 102 combine to form vertical tapering ducts for the combustion gases, and the lower portions 108 of the elements define a furnace 111, or at least a portion thereof. Heat-transfer fins 114 in channels 101 are of opposite inclination to similar fins 115 in channels 102 so as to form helical threads in each duct. Cylindrical lugs 104, 109 on the elements provide inlet ducts 105 and outlet ducts 110 for the water. From the inlet ducts 105, the water passes via the interior of the hollow portion 108 of each element to the hollow interior 103 and thence to the outlet duct 110. In another embodiment, in which the elements do not comprise the furnace, the heat-transfer fins of the two halves of each vertical duct are of opposite helical pitch and are offset with respect to each other.

Title: Apparatus for transferring a particulate material to a web
IPC: B05C19/00
Filed: 1969-12-27
Abstract: A device for adding a thermoplastic or thermosetting material to a receiving web includes means for distributing a particulate material throughout recesses or grooves defined on the surface of an endless member such as a continuously rotating drum. The grooves which have been filled with the material are then moved into association with a web of a material such as a textile material which is moved into contact with the drum and at the same speed as the drum while it is maintained at a temperature great enough to cause the tackiness and adherence of the particulate material to the web in the pattern defined by the grooves of the drum. The granules are advantageously directed to the top face of the drum as it rotates and the web is advantageously delivered to a location at which it feeds around a major portion of the lower part of the drum surface. A pressure roller is located at the infeed of the web and at the outfeed of the web and is advantageously maintained in a heated condition to provide a temperature to facilitate the transfer of the thermoplastic material from the grooves of the drum to the surface of the web. The particulate coating material is delivered to the backing material web at a coating station while the material is maintained at a temperature lower than that at which it is applied to the backing material. Conversely, the backing material is maintained at or heated to a temperature at which the particulate material will become tacky and move into adhering engagement with the backing material as it is transported into association therewith at the coating station.

Title: Apparatus for working flat, flexible material
IPC: C14B1/40
Filed: 1970-08-18
Abstract: This invention relates to apparatus for working flat, flexible material by means of working members opposing each other.

Title: Time-sharing subscriber communications system
IPC: H04N7/16
Filed: 1971-10-04
Abstract: A time-sharing subscriber communications system wherein a time-division multiplexed signal having a series of frames and a predetermined number of time slots in each frame is transmitted in a given frequency band over a single wideband circuit to a plurality of subscriber terminals. Various time slots contain information from various input channels which are respectively related to various ones of the subscriber terminals. The transmitted signal is modulated by a zero axis crossing modulation scheme wherein each time slot is defined by the interval between successive zero axis crossings and the information contained in each time slot is defined by the duration of the time slot. At each subscriber terminal the information related to that channel is tapped off from the signal received from the transmitter terminal, a portion of the received signal is retransmitted over the wideband circuit and new information related to the subscriber terminal is newly transmitted in one or more time slots of each frame of the time-division multiplexed signal. A receiver terminal, interfaced to the opposite end of the wideband circuit from the transmitter terminal, demodulates the newly transmitted information from the subscriber terminal and provides output signals to various output channels respectively related to various ones of the subscriber terminals.
