Title: Improvements relating to remote control and indication apparatus
IPC: H04Q9/00
Filed: 1964-08-11
Abstract: 1,080,052. Electric selective signalling. HONEYWELL Inc. Aug. 11, 1964 [Aug. 15, 1963], No. 32716/64. Heading G4H. In a supervisory system, one of a plurality of remote stations is connected over a common set of conductors to a central station by coordinate selection in a matrix of relays, one of the relays forming a part of each remote station, whereby measurement and control signals can pass to and from the central station respectively. In one arrangement, closure of one out of ten "hundreds" push-button switches connects one of ten 10 x 10 relay matrices to a set of ten " units " switches. Closure of one of the " units " switches and also one of ten " tens " switches energizes one relay in the selected matrix. One of two switches at the central station is closed to drive a motor at the remote location selected as above in one of two directions to adjust a damper in a building heating/ cooling installation. The damper is connected to a potentiometer which supplies a voltage representing its position to a meter at the central station. In addition, air flow past the damper moves a vane to close a switch which lights a lamp at the central station. A pen recorder is also shown at the central station. In a variation, a wiper replaces one set of push-button switches to select locations housing thermocouples in turn to transmit the thermocouple potential to a central station, where an alarm is given if it is above or below a certain magnitude, which depending on the identity of the remote location. This latter dependence is achieved by having a power supply for the central station transmitted from the selected remote location on one of two leads depending on whether alarm is to be given in the greater than or less than eventuality.

Title: Improvements in or relating to screw cutting machines
IPC: B23G1/04
Filed: 1920-11-23
Abstract: 175,102. Vickers, Ltd., McKechnie, Sir J., Fender, T., and Bateman, L. H. Nov. 23, 1920. Screwing.-A machine for cutting threads continuous in pitch on the opposite ends of boiler stays comprises a pair of die heads d, rotated in opposite directions from a driving-shaft B and traversed in opposite directions by a lead-screw C oppositely threaded on each side of its centre. One or both of the die-head carriages is provided with a fine adjustment relative to its lead-screw nut comprising screws d<9> and d<8>, d<10>. The leadscrew is driven through change-gearing h from a spindle which may be connected by a clutch member H to one of the pinions J, k, which are geared to the shaft B, the reversing movement being more rapid than the forward movement. The clutch member H is caused to engage the pinion J to impart the forward movement by means of a lever M operated by a starting-rod F. When the desired amount of screwing has been performed, adjustable stops e' act through levers E to open the dies d', the rod F being simultaneously rotated by gearing from a lever E to bring a feather f<3> into alignment with a keyway in a bracket n<3>. A stop f<2> on the rod F is then engaged by a projection d<5> on one of the die-head carriages, the rod F is thereby moved to disengage the clutch member H and the lead-screw stops. The movement of the clutch lever M moves a wedge m<1> past the wedge-shaped nose o of a spring plunger 0, which is thereby enabled to force the lever M into position to cause the clutch member H to engage the pinion and reverse the lead-screw. The reversing motion ceases when the bracket d<5>, by engagement with a stop, moves the rod F to bring the clutch member into its mid position, the wedge m<1> at the same time returning the plunger O to its initial position.

IPC: D01F1/10
Filed: 1931-12-08
Abstract: Artificial fibres having an irregular surface, a cellular structure and generally the characteristics of wool, are obtained by the addition to the coagulation liquid through which the bundles of extruded filaments pass in substantially straight lines, of finely divided insoluble substances, preferably such as have sharp edges or a large surface, for example, infusorial earth, powdered glass or carborundum, precipitated silicon oxide, fullers earth, decolourizing clays, and finely divided resins or artificial resins.  The suspended particles may or may not adhere permanently to the filaments.  Finely divided substances may also be suspended in the spinning solution; and it is preferred that these shall be different in size, shape, and physical conditions from those contained in the coagulation liquid. Dispersion of the particles may be assisted by the addition of sulphonated fats or fatty acids; and the effect of the added substances may be improved by the addition of adhesive substances such as 3-oxytrimethylene-1,2-sulphide.  In examples solutions of viscose, cuprammonia cellulose and cellulose acetate are employed for the spinning.  The Specification as open to inspection under Sect. 91 refers to the dispersion of solid or liquid substances in the form of smoke or mist in the heated air used in the spinning of nitrocellulose filaments.  This subject-matter does not appear in the Specification as accepted.
