Abstract: 1,174,942. Thermistors. INTERNATIONAL BUSINESS MACHINES CORP. 9 Jan., 1967 [13 Jan., 1966], No. 1112/67. Heading H1K. An electrical temperature transducer comprises a non-diffused resistance element of monocrystalline semi-conductor material inlaid in a base having an electrically insulating surface which forms the boundary of the resistance element. Fig. 1A shows the resistance element 14 inset in a glass or plastics (e.g. polytetrafluorethylene) base 12 with metal terminals 28. The element may consist of silicon, germanium (stated to have positive temperature coefficient of resistance) or gallium arsenide doped with acceptors or donors to a concentration between 5 x 10<SP>14</SP> and 5 x 10<SP>17</SP> atoms per c.c. The glass base may be composed of Al 2 O 3 , CaO and SiO 2 . The device may be produced by photoresist etching of a monocrystalline silicon wafer 30 (Fig. 3B) to form an embossed elongated resistance element 32 on the surface which is then covered with glass 34 by, for example, sputtering, sedimentation or fusing techniques. The bulk of the original wafer 30 is removed to leave the resistor inset and rhodium plating is used to provide terminals. In a modification, a thin insulating layer of oxide, nitride or carbide (e.g. SiO 2 , Al 2 O 3 , Si 3 N 4  or SiC) is provided between the resistance element and the base consisting of polycrystalline silicon. The element may be placed in a housing comprising base 52 with brackets 54 for clamping the transducer element 20. Contact pins 58 are soldered to metallic coating 64 on insulation 62 (boron nitride) on brackets 54 and flexible wires 70 connect the terminals of the transducer element 20 to coating 66. The base 52 and cover 56 may be made of a nickel, cobalt, iron alloy.

Title: Improvements in or relating to mains driven d.c. voltage supply stabilisers
Inventor: DOWNING ALBERT CHARLES
IPC: G05F1/565
Filed: 1969-01-09
Abstract: 1282721 Automatic voltage control MARCONI CO Ltd 29 Oct 1969 [9 Jan 1969] 1312/69 Heading G3R A high voltage D.C. supply is stabilized against variations caused by changes in the supplied load, but is at least to some extent dependent on changes in the driving voltage. In the embodiment of Fig. 1, a 3-phase mains input is rectified by diodes D and supplied by way of a choke CH and a series transistor T to output terminals OP1, OP2. A potentiometer PR1 is connected between the terminal OP1 and a stable negative source SN. A tapping on this potentiometer provides one input to a comparator C, the other input to which is derived from a potentiometer PR2 connected across a rectifier bridge RB which is also supplied from the mains. In operation, variation in the mains voltage may be arranged to affect each of the comparator inputs equally, so that the base potential of the transistor T is unaltered and the output voltage changes. However, a change in the output voltage due to variation of the load affects only the first input to the comparator, the bias on the transistor T being thereby adjusted to compensate for the load variations. In a further embodiment, Fig. 2 (not shown), one end of the potentiometer PR1 is connected to the tapping of potentiometer PR2 to provide a combined input to the comparator which is compared with a reference voltage, e. g. from a Zener diode. The circuit may be used as a supply for a tetrode operating as a linear amplifier.

Filed: 1973-01-10
Abstract: 1451897 Knitting machines I W S NOMINEE CO Ltd 4 Jan 1974 [10 Jan 1973] 1377/73 Heading D1C A plush fabric is knitted on a cylinder and dial machine by simultaneously feeding a plush yarn to cylinder and dial needles and a ground yarn to the dial needles only so as to form long loops in the plush yarn and short loops in the ground yarn and thereafter causing the cylinder needles to perform a knitting movement without yarn being fed thereto, whereby the plush yarn loops are pressed off the cylinder needles which then have their latches opened mechanically for a further knitting cycle. Attachments for converting a conventional machine to perform the method of the invention comprise an auxiliary yarn feeder (Figs. 1 and 2, not shown) with a yarn guide tube adjustable in both the horizontal and vertical directions for feeding yarn behind the cylinder needles directly into the dial needles; a pressure member with a blade 68 located behind the cylinder needles for holding down the plush loops at the position where the needles are raised without yarn being fed; and a unit mounted on a bracket 35 comprising a loop clearer device 31 having a blade 46 which guides the plush loops into the gap between cylinder and dial when they have been released from the cylinder needles; a latch opener device 32 with a spring loaded blade 53, a latch trip indicator 34 with a feeler 63 which trips a micro-switch to operate a lamp 64 or to stop the machine in the event of a faulty latch deflecting the blade 53 against its biassing spring 49, and a latch control deflector 33 having a blade 58 for holding open the latches opened by the device 32. In a preferred embodiment of the invention a machine having a multiple of six feeder positions is used with the following set-up at each group of six successive positions:-at position 1 even dial and odd cylinder needles are selected and knit both yarns, at position 2 the even dial needles knit ground yarn only, at position 3 the odd dial and even cylinder needles are selected and knit both yarns, at position 4 the odd dial needles knit ground yarn only, at position 5 no yarn is fed but all cylinder needles are raised to knit position with the plush loops held down by a presser member 66 and the loops are subsequently pressed off the needles, between positions 5 and 6 the clearer device 31 of a unit mounted at the latter position guides the loops between the cylinder and dial, and at position 6 all the cylinder needles are again raised and their latches opened by the device 32 in preparation for the next feed.

Title: Improvements in hydraulically operated oil storage tanks
IPC: B65D90/38
Filed: 1921-01-10
Abstract: 157,734. Farr, F. G. Oct. 8, 1917, [Convention date]. Direct liquid-pressure apparatus-In oil tanks wherein the oil is stored over a displacement liquid, such as water, means are provided within the tank whereby a variation in the volume of oil (due to filling or drawing-off) effects a complementary variation in the volume of water, thus maintaining a substantially-constant level of oil and preventing the drawing-in or displacement of air, so that the formation of an explosive mixture and the loss of the more volatile constituents of the oil are avoided. In the form shown in Figs. 1 and 3, variations in the level of the oil due to the introduction or discharge of oil through a pipe C affect a float H connnected by a rod J to a valve device G, whereby water is admitted through a pipe E when oil is drawn off, and is discharged through a pipe F when oil is introduced, thus maintaining a constant upper level of oil. In a modification, the rod J is secured to the tank roof, which has sufficient flexibility to respond to the slight changes in the internal pressure as oil is introduced or withdrawn.
