Title: Improvements in linear dimension dial gauges particularly for use with hardness testing machines
IPC: G01N3/42
Filed: 1944-08-01
Abstract: 586,143. Hardness tests; dial gauges. WOODHEAD & SONS, Ltd., J., and BERRY, W. R. Aug. 1, 1944, No. 14642. [Classes 106 (ii) and 106 (iv)] In a dial gauge, which may be used for measuring the depth of an impression made in a hardness test, the plunger of the gauge is coupled to the movable pointer or dial through a clutch which is engaged after the initial load is applied, so that the impression due to the subsequently applied load only is measured. The plunger 6 embodies a rack engaging a pinion 8 on a shaft geared through pinions 9, 10 to a shaft 14 carrying the core member 21 of an electro-magnetic clutch. The sliding armature 24 of the clutch is normally held disengaged by a spring and is coupled to a spindle 16 carrying the pointer 25 through pinions 18, 19, mounted on a spindle 15, and pinion 20 on spindle 16. A second pointer 27 serving as a revolution counter is mounted on the spindle 15. The clutch coils 22 are connected to terminal 30 through the shaft 14 and the casing 2, and to terminal 31 through a brush 35 pressing on a ring 23 on the core member. When the initial load has been applied, a switch is closed automatically to connect the terminals to a source of current. Indicator lamps 39 are connected to the terminal 31 and to segments 33 over which is adapted to move a contact arm 26 mounted on the spindle 16. The outer lamps are coloured and if lighted at the end of the test indicate that the piece under test is too hard or too soft. A spiral spring 29 returns the pointers on removal of the load. A helical spring is provided to keep the plunger 6 in contact with the part the movement of which is to be measured. Two dial gauges in tandem reading .001 inches and .0001 inches respectively may be employed. Audible signals may be provided to draw attention to rejections. The contact arm 26 may be adapted to control feeding and withdrawal mechanisms and sorting of rejected parts. Hold-on or resetting switches may be provided to prevent disengagement of the clutch until the initial load as well as the subsequent load is removed. When a gauge with a moving dial is used, small windows are provided in the casing to expose only the readings concerend. Arrangements of the gauge and control switch in both a hydraulic and a dead load machine are described and shown. Specifications 140,165, [Class 106 (ii)], and 417,881 are referred to.

Filed: 1937-06-26
Abstract: 497,932. Line-markers for roads &c. MORRISH, F. June 26, 1937, No. 14670. [Class 132 (ii)] A wheeled machine for marking roads, tennis courts, parking grounds, &c. includes a pad or the like adapted to be moved into and out of contact with road &c. and means for supplying paint or the like to the interior of the pad. As shown, the machine is mounted on three wheels the front wheel 4 being connected by a cable 8 to a steering bar 12. The axle 27 of the back wheels 2 is connected by chain gearing to a cam shaft 19 arranged to reciprocate (in a vertical direction) a spring-pressed ram assembly 13, Fig. 4, carrying a rubber pad 18. As the ram assembly reciprocates, it repeatedly depresses, into contact with the ground, a perforated dish-shaped pad 34 of rubber into which paint is run from a supply tank 36. A broken line is thus marked upon the ground as the machine is propelled, the propulsion being effected by a handle 6 or by a motor. For marking a continuous line, the ground wheels 2 are disconnected from the cam shaft 19 by the disengagement of a dog clutch 29 operated by a control lever 31 and flexible cable 32, the cam shaft 19 being set by means of a handle 44 and chain gearing 42 so that the pad 34 remains constantly in contact with the ground. The handle 44 may be used also to raise the marking pad from the ground during transport of the machine.

Title: Apparatus for detecting and controlling the presence of sewage sludge in a liquid
Inventor: HILL EDWARD SYDENHAM
IPC: G01N15/06
Filed: 1960-04-27
Abstract: 946,459. Automatic density control. COUNTY COUNCIL OF THE ADMINISTRATIVE COUNTY OF MIDDLESEX. April 27,1960, No. 14761/60. Heading G3R. Electrodes in liquid sewage are in the primary circuit of a transformer the secondary circuit of which is connected to the input of an electronically operated relay which is actuated when the conductivity of the sewage has a predetermined adjustable value. As shown, but with switches 4, 17 in their other position, one of several pairs of carbon electrodes, such as 32, 33, immersed in liquidfilled hoppers or tanks (not shown), is selected by a switch 30 and connected through leads 18, 19 to the 12v A.C. source shown that the current flowing through a potentiometer 14 is dependent on the conductivity of the liquid and hence the amount of sewage or other sludge present in it. If this amount exceeds a predetermined value determined by the setting of potentiometer 14 the signal applied to the grid-cathode circuit of a triode valve 1 is sufficient to overcome an opposing alternating bias voltage from a potentiometer 22 so that the valve conducts and energizes a thermal delay relay 6 which thereupon operates means such as pumps, valves and/or penstock motors to lower the concentration of sludge. By moving switches 4,17 to the position shown the predetermined value of sludge concentration at which the control operates is set by adjusting a potentiometer 29 until a milliammeter 28 indicates an appropriate current, and then adjusting potentiometer 14 until a lamp 23 operates. Instead of valve 1 operating as a switching device as described its output current may be made proportional to the amount of sludge by removing a condenser 10 so that the grid and anode voltages of valve 1 are not exactly in phase opposition. Switch 30 may be operated manually or may be operated automatically to detect the amount of sludge at different points in succession according to a predetermined programme. Switch 30 may also feed another similar system B maintaining sludge at a different concentration in a second stage of a setting out process, each system being connected for a time determined by time switches 37.
