Patent GB-894271-A (GB)
Abstract: 894,271. Axle counters. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. May 18, 1960 [June 4, 1959], No. 17493/60. Class 105. A railway signalling axle counter 1 comprises four magnetic detector devices 11 disposed on the ends of pole shoes 12 of two permanent magnets 13 which are mounted on a carrier 2 adjacent a track rail 3 in a position in which each vehicle wheel rim passes through the flux path between the detectors and the rail. The detectors may be transformers partially saturated by the permanent magnetic field and supplied from an A.C. source or may be detectors operated by Hall effect. The output of each pair of detectors associated with a permanent magnet is connected in opposition so that no output is present in the absence of a wheel flange. Where the rail forms a return for traction current a parallel circuit to the rail is formed by a bar 16 having the same impedance as the rail so that the magnetic field produced by the return current cancels in the space between bar and rail in which the counter is disposed. Where no discrimination between the two directions of travel is required, only one magnet 13 and two detectors 11 are required and these may be connected in a circuit, Fig. 7, which amplifies the signal produced before this is shaped 81 and registered in a counter 8.

IPC: E01H1/05
Filed: 1991-07-15
Abstract: A self-propelled cleaning vehicle comprises matter removal means including primary brushes 24, 26 and an additional or third brush 28. The third brush is mounted on a brush mounting arm 46 comprising inner and outer arm portions 48, 50, pivotally interconnected, and controlled by a control linkage interconnecting them and actuated by a remote actuating ram at the inboard end of the assembly. The outer arm portion is of telescopic construction for length-adjustment. The telescoping portion is provided by two parallel rams. Oil flow to the hydrostatic motor passes through the rams and their piston rods themselves. The pressure on the piston is used to telescope the rams. When the third brush is in use, contour-following means enables the inboard primary brush to follow the peripheral contours of a surface it is sweeping without driver intervention. Such automatic contour-following is activated by driver-controlled selection of a contour-following control mode which causes the inboard brush to move outwards until it meets, for example, a gutter profile. Position sensing switches enable the primary brushes to automatically adopt standard sweeping positions when a non-contour following mode is selected. <IMAGE>

Title: Operational amplifierwith self contained sample and hold and auto zero
Inventor: BERT WHITE
IPC: G11C27/02
Filed: 1993-01-27
Abstract: The switched capacitor amplifier circuit of the present invention employs a single amplifier with a built- in sample and hold and input auto zero. The built-in sample and hold of the present invention provides a continuously valid output in a multi- phase system. The present invention comprises a new auto zero configuration and a new amplifier. The new amplifier is referred to as the AZAMP (42). The circuit configuration of the AZAMP (42) of the present invention comprises a two stage amplifier (71, 75) with switches (M21, M23) added to the circuitry to provide the sample and hold function. By disconnecting the second stage (75) during the hold mode, the output voltage will remain unchanged due to the voltage stored on a capacitor (C7) within the AZAMP (42). Charge cancelling circuitry (C9, C10, M22, M24) is coupled to the sample and hold circuitry to cancel the charge injected onto said capacitor (C7) when the switch (M21) is turned off. The AZAMP (42) of the present invention also has a self-contained auto zero function. The resulting benefits are reduced area consumption and low input equivalent offset. <IMAGE>
