Title: Improvements relating to flight indicators for aircraft
IPC: G01C17/00
Filed: 1934-10-29
Abstract: 435,355. Magnetic compasses; gyroscopic apparatus. HILLIER, A., c/o Sperry Gyroscope Co., Great West Road, Brentford, Middlesex.-(Sperry Gyroscope Co., Inc. ; Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.) Oct. 29, 1934, No. 31019. [Classes 97 (ii) and 97 (iii)] A magnetic compass card, adapted to be read from the side, is mounted on the casing of a gyro vertical so as to be free to turn in azimuth without tilting relatively to the casing and forms an indicator visible in a lateral direction of the azimuth direction and longitudinal and lateral inclinations of an aircraft. As shown, the compass card 1 is supported on pivots 4, 5 in a casing 2 carried by the frame 3 of an air driven gyro-vertical of the type described in Specification 393,695. The frame 3 pivots on fore-and-aft trunnions 9, 10 in a gimbal ring 6 pivoting in turn on transverse trunnions in the outer casing 5<1>. The trunnion 10 is of large diameter and hollow so that the compass card is visible through windows 25, 26. Reference lines on the outer portion of the trunnion 10 and bearing 10<1>, and on the face of the instrument provide indications of pitch and bank simultaneously with the indications of the magnetic compass. In a modification the trunnion 10 is dispensed with, the ring 6 carrying the frame 3 by transverse trunnions and being pivoted on a single long trunnion at the rear. A window is provided in the ring 6 at the front.

Title: Improvements in and relating to metallic diaphragms
IPC: F16J3/02
Filed: 1932-11-04
Abstract: 414,711. Pump diaphragms. BECHERT, P., Saaz, Czeoho-Slovakia, and SCHMIDT, R., Sch÷nb³hel, near Melk, Austria. Nov. 4, 1932, No. 31168. [Class 122 (i).] Metallic diaphragms for reciprocating engines are provided with corrugations 4 which attain their maximum amplitude M between the inner diameter d<1> and the mean diameter d<m> of the grooved portion and nearer to the latter. The diaphragms may be made of one or more complete or partial laminµ. The blank prior to the impression of the corrugations, may be plane or undulated in form and the thickness may taper gradually or stepwise from the inner to the outer diameter. Where diaphragms are arranged to act oppositely in pairs, they are united at their outer edges in various ways such as by means of an intermediate welded-in ring, by bending one free edge over the other and enclosing the edges in a rubber ring or by inserting a wire between interengaged teeth on the edge and enclosing the whole in a rubber ring. British Specification 241,511, [Class 64 (ii)], and U.S.A. Specification 1,822,450 are referred to.

Title: Locking device for vehicle doors
IPC: E05B65/08
Filed: 1924-12-30
Abstract: 227,112. Kellner, A., (Assignee of Hannebohn, C. W. A.). Dec. 31, 1923, [Convention date]. Hook fastenings.- Vehicle doors are secured against opening and against rattling by a pivoted hook to which is pivoted a rod having a ring at its free end in which works an eccentric disc turned by an operating handle to engage and tighten the hook on a pin. The hook has spring means for retaining it against protrusion when the door is open, to avoid bending the hook if the door is slammed. In the form illustrated, the hook and operating mechanism are carried in the thickness of the door and the pin, with which the hook engages, by the frame. The hook d is pivoted at e<1> and the rod c has a ring m at one end and is pivoted to the hook at eat its other end. A disc l turned by the handle o about the eccentric axis n moves the rod c to engage the hook with the pin k, the disc can be turned past the dead centre until the flattened part of the ring rests on the plate p. This tightens the hook on the pin k and prevents rattling and accidental disengagement. When the hook has been withdrawn and the door opened, a spring plunger 8 is released from its engagement with the door-abutment 9 and shoots forward so that the tongue 2 carried by it engages in the notch 1 in the hook and retains it within the door. When the door is closed, the abutment 9 presses the plunger 8 inwards and moves the tongue 2 out of register with the notch 1 to allow the hook to be operated.

Patent GB-844162-A (GB)
Title: Improvements in or relating to combinations of statistical machines
Inventor: RIGBY IVOR VIVIAN
Filed: 1956-10-15
Abstract: 844,162. Statistical apparatus; verifying record cards. INTERNATIONAL COMPUTERS & TABULATING Ltd., Sept. 25, 1957 [Oct. 15, 1956], No. 31290/56. Class 106 (1). To check the accuracy of summary cards punched at each group change in a tabulator, the detail cards are passed through the tabulator a second time and the values in the accumulator are compared at the end of each group with the values sensed from the summary card in an auxiliary card feeding and sensing machine. This check is made when the grand total on the tabulator and the total in an accumulator on the summary punch differ and it becomes necessary to discover which summary card is wrongly punched. If the comparison on the individual summary card shows agreement, the next group of cards is fed through the tabulator and the next summary card is sensed in the auxiliary machine. If there is disagreement, a summary punch makes a new summary card. The system is shown diagrammatically in the Figure. The detail cards 108 from hopper 101 pass through the tabulator sensing brushes 109, 110 which detect group change and initiate total-taking. The summary cards 104 are placed in a hopper 102 of the auxiliary machine and blank cards 105 are placed in the hopper of a summary punch. At a group change the group change detector sends a signal to the accumulators 111 to make the usual total taking operation and it also sends a signal to a cycle control unit 112 which starts a cycle of operations in the auxiliary machine. This causes the summary card 104 corresponding to the card group just ended to be fed through the sensing station 14 and the data compared in the comparator 113 with the values in the accumulators 111. For this purpose an emitter operating in synchronism with the card-sensing causes selective energization of the first coils of differentially wound relays the other coils of which are connected to be energized by the read-out from the accumulators 111 through commutators UC1, UC2, UC3. Where the data signals from both the card 104 and the appropriate accumulator 111 are the same the relays do not respond. A difference causes the relays to operate. Where there is agreement the next operation of the cycle causes the accumulators to be reset ready and detail cards to be fed for the next checking operation. In the case of disagreement, the re-starting of the tabulator is prevented and punching unit is started over magnet PMC to punch into a blank 105 the data set up in the accumulator and passed to punch selector magnets PM1- PM3. This new summary card is visually compared with the original summary card at the top of stack 107 to determine the cause of the error. If the difference between the values on the two summary cards equals the difference between the final total of the tabulator accumulator and the total in the punch accumulator it may be assumed the error is corrected and the new summary card replaces the original one. If not, the process is continued. Specifications 442,135, 422,179 and 422,534 are referred to.
