Title: Method for determining random coincidence count rate in a scintillation counter utilizing the coincidence technique
IPC: G01T1/20
Filed: 1977-05-27
Abstract: 1527339 Determining random coincidence count rate BECKMAN INSTRUMENTS INC 27 May 1977 [7 June 1976] 22394/77 Heading G1A [Also in Division G4]  For use with a scintillation counter with two detectors 12 for coincidence counting, a method of determining a random coincidence count due to events which by chance occur simultaneously and are thus erroneously counted as radio-active disintigrations of the sample 10, comprises counting the number, CPM, of coincident events detected by both detectors, counting the number, CPM2, of events detected by both detectors regardless of coincidence, and from these results determining the random coincidence count rate as Tc/2(CPM 2  - CPM 1 )<SP>2</SP> where T c  is the resolving time of coincidence. A coincidence signal from coincidence circuit 20 together with signals from pulse height analysers 18 enable AND gates 22 feeding scalers 26. Control circuit 28 sets the limits for analyzers 18 and if it gives a logic 'one' signal to OR gate 34, gate 24 passes pulses regardless of coincidence, so that CPM2 is measured in channel #2. Circuit 40 determines the random coincidence count rate. CPM 1  is measured in channel #1. For CPM 1  and CPM 2  the pulse height discriminators are set for a window from zero to maximum. The embodiment of Fig. 3 (not shown) has another scaler.

Title: Gear shift mechanisms for motor vehicles
Inventor: BEATTIE PETER EDWIN
IPC: F16H61/34
Filed: 1965-05-26
Abstract: 1,049,955. Change-Speed control. FORD MOTOR CO. Ltd. May 26, 1965, No. 22480/65. Heading F2D. To prevent overshooting gear-establishing movements during cross-shift changes in a motor-vehicle gear-shift mechanism having a gear-shift lever 4 universally mounted on a rearward extension 1a of a gear-casing 1, and actuating the selector mechanism through an axially moved cross-shift rod 2 which rotates a selector arm (not shown) into engagement with one of three selector rods (not shown), and an axially moved rod 3 which moves the selected selector rod axially for gear establishment, as described in Specification 1,010,968, the crossshift rod 2 is resiliently connected to the gearshift lever 4 through springs 15, 16 which yield when cross-shift movement is prevented. Thus during a shift involving a cross-shift movement, the latter movement can be applied to the manual lever before any movement in the gear establishing direction, the actual crossshift movement of the rod 2 being produced by the pre-loaded spring 15 or 16 when the crossshift rod 2 is released by the subsequent gearestablishing movement reaching neutral position. The gear lever 4 pivots on a stud 9 on a bracket 8 which pivots about an axis A in a bracket 5 bolted to the gear-casing. Bracket 8 is fast with a stud 6 carrying a finger 10 which engages a notch in an arm 11a of a bellcrank lever 11 which pivots about a stud 14 and has its other arm connected through the springs 15, 16 to the cross-shift rod 2. Pivoting of the gear-lever about the axis A rotates the bracket 8 and, through the bell-crank lever 11, loads either spring 15 or 16 to shift the rod 2. The lower end 4c of the gear lever 4 is located in a slot in one arm of a lever 12 which is pivoted at 13 to the bracket 5. The slot extends parallel to the stud 9 so that pivoting of the gearlever about the axis A will not cause the lever 12 to move. Pivoting of the gear-lever about the stud 9 rotates the lever 12 about the pivot 13 to shift the gear-establishing rod 3 axially.

Title: Improvements relating to automatic ignition timing devices
IPC: F02P5/07
Filed: 1944-11-16
Abstract: 590,512. Timing ignition. LUCAS, Ltd., J., BURGESS, W. H., and McGOWRAN, A. P. Nov. 16, 1944, No. 22724. [Class 7 (iv)] In an automatic ignition timing device in which the moment of ignition is controlled by a centrifugal mechanism and a mechanism responsive to induction pipe depression in pressure and the mechanism responsive to depression in the induction pipe acts in one direction on increasing depression but operates in the reverse direction when the depression exceeds a predetermined limit the timing adjustment is effected by rotating a member carrying the ignition interrupter and the mechanism responsive to induction pipe depression comprises in part a pair of interconnected links. In one arrangement as shown the ignition cam c is operated in the usual way through a centrifugal mechanism and the interrupter a is carried on a rotatable member b. A diaphragm d subjected to pressure in the induction pipe is connected by rods i and springs m to the rotatable member. The rods have slots k making lost motion connections with pins j on the rotatable member and the springs m are connected between the rods and the pins j. One spring is stronger than the other. When the diaphragm is operated by the depression in the induction pipe it first rotates the member by extension of the weaker spring about the left hand pin. When this pin comes against the end of the slot the member is rotated in the reverse direction by extension of the stronger spring. Instead of one spring being stronger than the other one may be mounted further from the centre of rotation than the other. In an alternative construction a pair of levers connected by a common pivot which is connected to the diaphragm are pivoted one to member b and the other to the housing of the device.
