Title: Ice condition detecting device
IPC: G01N25/66
Filed: 1964-07-09
Abstract: 1,071,752. Ice-detecting apparatus. HOLLEY CARBURETOR CO. July 9, 1964 [March 30, 1964], No. 28349/64. Heading G1N. A device for preventing the formation of ice on a surface compares the output of a device measuring saturation temperature with that of a device measuring the temperature of the surface and operates a heater when the first exceeds the second provided also that the surface is near to freezing point. The basic system is shown in Fig. 1. An A. C. -fed capacitor (see below) feeds a signal proportional to absolute moisture content and hence to saturation temperature of the air to a gate circuit 24. This circuit is also fed with the output of a surface temperature measuring thermistor 28 which opens the gate only when surface temperature is approaching freezing point. If it is, both outputs are fed after suitable rectification and amplification to a differential amplifier 32 which compares them and, if surface temperature is lower than saturation temperature, operates a relay to switch on a surface heater 62. In an elaboration Fig. 10 (not shown) a further condenser is incorporated which responds to the presence of free water (e.g. rain) and if the surface temperature is near freezing, overrides the saturation temperature measuring device to switch on the heater. This free water sensor may also operate to keep water out of the moisture sensor. The saturation temperature sensor Fig. 2 (not shown) consists of a cylindrical capacitor having outer and inner electrodes 66, 70 between which is sandwiched an intermediate sensitivity grade of polyvinyl alcohol called Elvanol. This material is said to acquire a surface film of moisture which varies the capacitance to give an indication of absolute moisture content. The outer electrode is perforated to allow the moisture to reach the dielectric and a cone 110 guides the air flow into axial passages around the electrode. To maintain the temperature of the detectors above dew point a central heater is provided and a thermistor is embedded in an epoxy resin filled cavity in the inner electrode. In further arrangements. Figs.6-9 (not shown) the inner electrode is also perforated and when no longitudinal air flow is provided the air enters the assembly through the circumferential walls of the housing and an arrangement is also described in which the air flows over flat electrodes plates which are adjustable to and from each other. The entire sensor may be situated in a heated housing Fig. 11 (not shown). Free water sensor this consists of a pair of electrodes with an intermediate dielectric as already described but the electrodes are spaced from the dielectric to allow free water to flow through and the dielectric to dry off.

Title: Improvements in or connected with mechanism for imparting to a support, carrier or the like, movements of a determined character, in or connected with apparatus comprising material distributing appliances, cutting devices, or the like
IPC: A23G3/28
Filed: 1920-10-14
Abstract: 174,152. Mackenzie, H. W. Oct 14, 1920. Engraving.-The invention relates to apparatus for manipulating distributing nozzles of extrusion apparatus or engraving cutters, of the kind comprising a movable member mounted to move in a plane so that any straight line in the member parallel to the plate remains approximately parallel to its original position, and consists in means for imparting to the movable member movements of an arbitrary character, determined by guides or by the operation of directing mechanism. The apparatus is adapted for use in distributing material as for making cakes, biscuits, &c. or applying decorative coatings to formed articles, and, as shown in Fig. 1, comprises a series of distributing nozzles G of an extrusion apparatus adapted to be operated and then traversed laterally for subsequent operations. Rotating cutters for engraving &c. could similarly be mounted, either fixed above a movable table or as part of a carrier to which motion is applied as described, the articles to be operated upon being placed on a fixed or movable bed. In the form shown in Fig. 1, a table A is mounted to move on a guide rod 1 fixed at right-angles to guides 2 sliding in brackets. Movements, as referred to above, are imparted to the table by means of a rocking arm B which passes through a spherical bearing C, adjustable vertically by a lever 3, and engages in a socket 4 on the underside of the table. Motion is imparted to the outer end of the arm B by the mechanism shown in Fig. 5, comprising a pair of lobe gear wheels E, F each formed with a pair of recesses in which the end of the arm can be placed. The wheel E turns with a gear wheel 8 on the underside of a wheel D which is driven from a power-driven pinion 5, the motion of the wheel 8 being derived through a train of spur wheels. The wheel E drives the wheel F. In the construction shown in Fig. 8, the table A rests simply upon a bed H, movements being communicated to it by a pair of arms B to which corresponding rocking movements are imparted. Two independent power drives are indicated, but one wheel D may be power driven and the other driven from it by a connection. The lobe wheels E may be similarly driven. Fig. 11 shows a stationary diagramguide K along which the arm B is moved by a power-driven wheel K<1> formed with a radial slot through which the arm B passes. Fig. 15 shows the arm B supported in a gimbal bearing. Coaxial with one of the supporting axes is a driving pinion L gearing with a toothed wheel N with which the arm is connected to rotate whilst being free to move endwise therein. The arm B is shown provided with a pinion R engaging with a rack T and is constrained to move along a guide. According to the Provisional Specification, the movable member may be moved by hand, either quite freely or in accordance with a diagram.

Title: Stud welding tool
IPC: B23K9/073
Filed: 1973-06-21
Abstract: 1412553 Supply circuits for stud welding apparatus HILTI AG 21 June 1973 [12 July 1972] 29431/73 Heading H2H [Also in Division B3] A stud welding tool comprises a welding pistol 6 having a trip circuit including a switch 18, a relay A and a contact 19, the trip circuit permitting welding with interchanged polarity of the welding lines 5, 9 and being connected to each welding line via a respective rectifier 11, 12. When the pistol is placed on material 8 to which a stud 7 is to be welded, the contact 19 on one of the feet 20 connects the trip circuit to the welding line 9. The trip circuit is supplied with A.C. by a transformer 14, 15 so that when the switch 18 is closed, the relay A is energized during half cycles of one polarity via the contact 19, the lead 9 and the diode 11, and during the other half cycles via the stud 7, the lead 5 and the diode 12. The relay therefore closes its contact a to supply welding power from a condenser battery 1 to the welding lines. Interchanging the leads 5, 9 does not affect the operation of the trip circuit and if welding is to be carried out by the method in which the stud is initially separated from the material 8 current flows in the trip circuit only during half cycles of one polarity of the A.C. supply. This current is, however, sufficient to energize the relay A. A holding circuit for the relay A may be provided including diodes d1, d2 and a further contact a 1  of the relay. A modified circuit is described which prevents welding by the method in which the stud is initially separated from the material 8 if the stud is in contact with the material. The contact a may be replaced by a thyristor.

Abstract: 1400362 Waveguide joints INTERNATIONAL STANDARD ELECTRIC CORP 21 June 1973 [26 June 1972 24 Aug 1972] 29503/73 Heading H1W [Also in Division H2] To connect two identical cylindrical waveguides without introducing dimensional discontinuity in the bore of conductor 1, a length . of conductor is removed, the wrapping if any of a further length on one end and a lesser length on the other being rolled back to later reinstatement, and a brass sleeve 12 with resilient threaded ends 12B, slotted at every 90 degrees, internally knurled and carrying nuts 14 loosely, fitted, is slipped over one.end (that with more wrapping, if any, removed). The ends of the two conductors are slit and splayed slightly 1A to accept thin tapered ends 9A of steel conical tubes 9 with cylindrical bores of diameters equal to those of conductors 1. Copper tube 16 with longitudinal slit 16A is fitted in the gap between the inner ends of tapered tubes 9, and is closed by a tool to bring its bore down to match that of conductors 1, at which state slot 16A should be closed. Sleeve 12 is then centred over the joint to clamp the conductors 1 on to both conical tubes 9 by the tightening of nuts 14, squeezing tapered surfaces 12E of the sleeves 12 inwards, the knurled inner surface resisting any tendency to longitudinal movement on the waveguide. In an alternative embodiment (Fig. 1b, not shown) the sleeve 12 is split longitudinally into two pieces, retained at the correct spacing by two spring C washers with inward lugs, clipped on to one sleeve member, together with a spring ring almost surrounding both members in a groove formed round their centre section. Each member carries two slots at 90 degrees in its threaded ends: the copper tube 16 is eliminated in this embodiment, and the sleeve is assembled in situ, having inner diameter equal to that of conductors 1. In both embodiments the nuts 14 and parts 12C of the sleeve with parallel threads, and tapered sections 14A, 12E, may be replaced by taper-threaded nuts and sleeve. The invention may also be applied to coaxial cables, with suitable arrangements for joining and centering with polythene spacers the inner conductors.
