Patent GB-897651-A (GB)
Title: Method and apparatus for analyzing the performance of an internal combustion engine
IPC: F02P17/02
Filed: 1958-09-11
Abstract: 897,651. Regulating. MARQUETTE CORPORATION. Sept. 11, 1958 [March 11, 1958]. No. 29117/58. Class 7(6). [Also in Group XXXVI] Shunting of the contact points of an I.C. engine for a selected portion of a cycle during a running test is effected by a thyratron which is rendered capable of conduction at a selected point and for a selected duration which may be sufficient for the disablement of two or more cylinders. Each of the high tension impulses from the engine triggers a thyratron V1 to discharge a capacitor C3 which thereupon recharges at a rate dependent on the setting of a variable resistor R2 to produce a saw tooth wave at the grid of a high-mu hard triode V2. At a given value of the saw-tooth voltage V2 becomes conducting and stops conduction in V3 for the time taken for capacitor C4 to discharge through the selected one of resistors R3..R5. This results in the application of a positive pulse to the grid 28b of thyratron V4. Switch S5 being closed, the thyratron is thus an effective shunt to the contact breaker points for the duration of the pulse which begins at a time determined by the chosen value of R2 and continues for a period which may cover several ignition pulses as selected by R3 to R5. Where the live breaker point is negative, switch S3 is operated to bring in transformer Tl the secondary of which when loaded by the thyratron in conductive condition makes the primary an effective shunt to the breaker. A transformer T2 in the cathode of thyratron V4 may be switched to produce an impulse which may be used in place of the input trigger pulse so that when the cyclic shunting of cylinder one spark is required, the auxiliary pulse can be caused to suppress the next cycle. Oscillographic analysis of ignition, speed, torque, horse-power, or manifold pressure is referred to.

Title: Improvements in or relating to a record changing mechanism for a magazine gramophone
IPC: G11B17/16
Filed: 1947-11-06
Abstract: 643,889. Automatic gramophones. COSTA, H. DA, and PLESSEY CO., Ltd. Nov. 6, 1947, No. 29584. [Class 40 (ii)] In a magazine gramophone in which the records are supported and stabilized solely by the turntable spindle, a lower retractable support is provided which is separated by a collar from an upper displaceable means which is caused to displace the next record so that it is supported on a sheaf formed by part of the collar when the bottom record is released from the lower support. The Figure shows a turntable spindle in which the stack of records is supported by the expanded end portion of sleeve 6. Upward movement of slidable tube 9 compresses the end portion of sleeve 6 so that the lowest record is released on to the turntable. A collar 10 having a thickness equal to that of a record is fixed above sleeve 6 and a divided sleeve element 11 is provided above collar 10. Rotation of spindle 1 which has a flat portion at each end, in sleeve 4, results in one portion of sleeve 11 being laterally displaced by ball 5 whereby the record next to the lowermost record is moved sideways so that it is then supported by the edge of collar 10. When sleeve 6 is expanded, after releasing the bottom record, spindle 1 is again rotated so that the displaced portion of sleeve 11 restores, and the record stack then falls from shelf 10 on to the support 6. Any suitable automatic means may be used to raise tube 9 and rotate spindle 1. The divided sleeve 11 is surrounded by a housing 14 which is retained in position by means of a spring 15. The two portions of sleeve 11 may be urged together by means of a surrounding spring. Specification 600,466 is referred to in the Provisional Specification.

[Class 78 (iv).] Relates to sinking shafts by blasting, and to arrangements for facilitating removal of spoil. In Fig. 1, a shell A is lowered into a fore-shaft O, shot holes are drilled and charged at both faces M, K, and the shots fired, those in the face K merely detaching the rock and those in the face M being such as to throw the rock against baffle C which deflects it into the space P ; the baffle C, or a skip, is then lowered into the shell A, and apertures L are opened for passage of the rock thereto. In Fig. 2, the baffles C are carried by a superstructure R above the shell A and may swing about pivots t to allow passage of a skip &c. In Fig. 6, a skip l, with a hinged bottom held open by a transverse strut, is lowered into a shell D and the face M is blasted, displacing the strut so that the bottom closes and catches the falling rock ; the skip l is then removed and an ordinary skip is lowered to receive material from the face K. In Fig. 8, a cylinder B is slidable in the shell A ; the faces M, K, are blasted simultaneously or separately and a skip is lowered depressing cylinder B to allow the spoil to pass to the skip or the baffle may be lowered and raised and may serve as a skip ; the cylinder B rises when the baffle or skip is removed. In Fig. 9, a self-lowering bell D supports a bunker E within which are slidable cylinders T, B ; face M is blasted, the material being caught in bunker E and a skip lowered to depress cylinder T. Alternatively, the cylinder B may be raised, a skip lowered into the fore-shaft, and the face K blasted, the rock being guided into the cage by the bell D.
