Title: Improved apparatus for weighing vehicles in motion
Inventor: HATTON JOHN SAMUEL
IPC: G01G3/142
Filed: 1964-11-21
Abstract: 1,123,356. Measuring weight of moving vehicles electrically. W. & T. AVERY Ltd. Nov.9, 1965 [Nov. 21, 1964], No.47486/64. Heading G1N. To obtain the static weight of a moving vehicle 1 (Fig. 2) its weight is sensed by load cells 4 (strain gauges on a D.C. bridge) supporting a rail section 3 over which the vehicle passes and the initial peak value of the load cells' output voltage (Curve A Fig. 1) is sensed and therefrom is formed an estimate of the static weight. It's assumed that the ratio of the peak value of curve A to the correct static load weight (voltage level B Fig. 1) would be constant at approximately 3:2. The cell output is fed via a filter inductance Z 1  to charge a capacitor Z 2  of the filter circuit. The response of the filter to the wave form A is illustrated by curve D. To enable the filter output to approach the correct weight level B more rapidly, so that in a time T, before the first set of wheels pass from the rail 3, it will be close to the correct weight value, the capacitor Z 2  is pre-charged rapidly to a point B on a curve E, and approximating the correct weight value during a period, determined by a pulse operated transistor switch circuit 11, immediately following the peak of curve A. When the switch circuit 11 is closed in response to the arrival of the leading wheels on to the section 3, the capacitor Z 2  is precharged from a short time constant circuit including an attenuator 8 and a peak detector and peak storage circuit 7, and via Z 1  from the load cell output. The transistor switch 11 then opens terminating the pre-charge and the strain gauge bridge output operates to charge the capacitor Z 2  via Z 1  only, substantially to the voltage level B at the time T. The voltage across capacitor Z 2  at the instant T is representative of the weight carried by the vehicle wheels which are passing over the rail section 3, and may operate an indicator or recorder. A time delay circuit (28) Fig. 3 (not shown), may be used to generate a pulse which disconnects the filter circuit from the load cells just before the moving load leaves the weight section 3 and which connects the filter output Z 2  voltage to an indicator.

Abstract: 1401497 Measuring temperature electrically PPG INDUSTRIES Inc 16 Oct 1972 [16 Nov 1971 1 Sept 1972] 47564/72 Heading GIN [Also in Division H5] In order to prevent damage to a resistance filament temperature sensor used in a transparent window, it is encased in a transparent casing which is of higher resistance to applied heat and pressure than the transparent layer which forms or is a part of the window. The case may be a polycarbonate or acrylic polymer. The transparent layer may be polyvinyl butyral which may be plasticized with water-insoluably esters of a polybasic acid and a polyhydric alcohol. An acrylic layer may be introduced between the casing and the layer to prevent migration of the plasticizers into the case. A polyurethane adhesive layer may be used to prevent delamination between sensor case, protective layer and embedding layer. The sensor case is fused with the layer using heat and pressure. The sensor 41 (Fig. 4) comprises a resistance filament 23 e.g. tungsten, nickel, iron-nickel alloys) lead wires 39, 40 of copper and connection tabs 51 of nickel-iron mounted on polycarbonate or acrylic polymer card 43, there being provided spacers 47 of a similar material and the transparent casing comprising layers 54, 55. The connections to the tabs 51 are made by soldering or welding. Figs. 5 6 (not shown) illustrate additional protective and/ or adhesive layers. Fig. 1 shows a window incorporating the sensor 21. The window comprises transparent sheets 3, 5 e.g. glass having a film resistance heating element 13 and electrodes 15 formed on one sheet; and a transparent layer of plastic material 12 formed by laminated sheets into which the sensor in its protective case is embedded. A temperature control device 27 adjusts the heating current in response to resistance variations in the sensor by modifying the output voltage of the source. The heating element may be of wires &c Fig. 7 (not shown).

Coarse adjustment: as the warp diameter decreases the feeler (82) and a cam (77), pivoted about (78), turn anticlockwise and a spring loaded follower (75), pivoted about (71), pushes a slide block (69) and a link (68), pivoted at (66), to the left to pivot a two-armed lever (64) about (63) to adjust the variable belt drive.  Fine adjustment: As the warp tension increases the back rest (6), pivoted at (4), lifts a link (84) connected to link (68) which has a slot (68a) embracing the slide block (69), the top end of the slot being further from the pivot (66) than the bottom end. As the link (84) lifts the link (68) pivots about (66) and the action of the slot (68a) on the slide block pushes the link (68) to the left to again pivot the two-armed lever (64) about (63) to adjust the variable belt drive.

Abstract: 1482868 Fusible cut-outs H SCHURTER AG 25 Nov 1975 [20 Dec 1974] 48448/75 Heading H2G A fuse holder comprises a tubular sleeve 1 of insulating material and a cap 9 also of insulating material and insertable into sleeve 1 in which it is retainable by complementary bayonet elements 8 and 10 in the sleeve 1 and cap 9 respectively, the bayonet elements 8 and 10 being cylindrical in form and of substantially the same diameter. As shown, the element 10 has two projections which engage in corresponding recesses in element 8 when the cap is pushed from the disengaged position to a position flush with the sleeve end and rotated to effect locking, Fig. 2 (not shown). Elements 8 and 10 are formed of conducting material, element 8 being connected to a tab 3 extending through the sleeve wall and element 10 being integral with a cylindrical member 100 within the cap and containing a contact 101 in which an end of a fuse 11 is a push fit. In the locked position of the cap 9 the other end of fuse 11 engages an end contact 4. A tab 2 extends from the contact 4, the tabs 2 and 3 being suitable for soldering to a printed circuit board. A spring 12 in head 9 serves to press the fuse against contact 4. Element 8 is recessed in a slot in the sleeve the radial width of which is much less than the sleeve bore so that the fuse end cannot contact the element, whilst the distance between the edges of element 8 and the sleeve is greater than the length of element 10 and that portion of member 100 not within the cap so that elements 8 and 10 cannot engage until the exposed conducting material is within the sleeve. Cap 9 can be rotated for locking by means of a slot 14. In a modification, Fig. 4 (not shown), the bayonet elements are stamped out of a strip and only a single projection and corresponding recess are provided.

In operation, the turret is indexed a predetermined number of times in a complete work cycle to present selected tool units to the work position in which a single one only of each identical tool unit is presented to the work position during a single work cycle. To determine which of the tool units is to be presented to the work position a selector 62 or 63 is provided which is automatically or manually operable in relation to an indexable member 50 which is indexable with the turret and has a cam 56 which actuates limit switches 52 the cam actuating each switch in turn as the turret and member are indexed and when a limit is effective, which is determined by the selector 62 or 63, the turret which stop in the corresponding position. The grouping of similar tool units in consecutive tool stations permits the changing from one tool to an identical tool in the work cycle without interruption of the machining cycle so that blunt or broken tools can be replaced without stopping the machine tool. In the embodiments described with reference to Figs 5 to 13 alternative means are disclosed for securing the tool units to the turret at the respective work stations. Each of the tool units has a shank portion which is locatable in a recess in the turret, and a head portion to which a cutting insert is attached. Figs. 5, 6, 8 and 9 show the tool unit shank is secured by a clamp or wedge member with a transverse pin to ensure rotation is prevented.
