Title: Improvements relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1926-12-21
Abstract: 265,554. Sperry Gyroscope Co., (Assignees of Gillmor, R. E.). Feb. 4, 1926, [Convention date]. Gyroscopic compasses. -The pendulous or gravitational control factor of a compass is made adjustable in accordance with the latitude so that the ballistic deflection resulting from a change of course or speed is rendered correct for the latitude in which the change occurs. In the form of compass shown the gravitational control is provided by a pair of liquid-containing vessels 11, one on each side of the casing 5, connected by a tube 12 and carried by a frame 10 which is mounted on pivots 8, 9 on the follow-up ring 3, and is connected at 13 to the casing 5. The control factor is adjusted by varying the effective area of the liquid 14 in each vessel 11, for which purpose a piston 16 can be moved along the vessel by a screwed rod 18 engaging it, the rod being turned by a head 21. To prevent disturbance of the balance of the compass the liquid is permitted to flow from cne side of the piston to the other along an axial bore 24 in the rod 18, and a hole 25 controlled by a needle valve 26. For indicating the position of the piston there is provided a rod 28<1> having a very coarse thread so as to make only one turn between the limiting positions of the piston. This rod is threaded in a bushing 30 in the piston and is provided with a. dial 31 graduated in degrees of latitude. Specification 131,987 is referred to.

Title: Improvements in or relating to vehicle direction indicator systems
Inventor: TURNEY ERIC JAMES
IPC: B60Q1/38
Filed: 1954-11-10
Abstract: 773,811. Road-traffic signals on vehicles. GENERAL MOTORS, Ltd. Oct. 6, 1955 [Nov. 10, 1954], No. 32548/54. Class 118 (2). [Also in Group XXXVII] A vehicle direction indicator system of the flashing light type comprises front indicator lamps 15 and 17 and rear indicator lamps 16 and 18 connected respectively to the terminals 10, 8, 6 and 4 of a selector switch 1. A battery 20 feeds a central terminal 9 on the switch 1 via a flasher 22. A second terminal on the flasher 22 feeds two pilot lamps 32 and 33 connected to terminals 7 and 11 on the switch 1, as shown. The other control terminal 5 on the switch 1 is fed from buttery 20 via a stop-light switch 19. In the switch 1 is a slidable insulator carrier (not shown) which supports a straight bridge contact 12 and two L-shaped bridge contacts 13 and 14. This carrier is selectively movable in an arcuate path to either side of the position shown by a finger (not shown) manually operable by the vehicle driver, the switch 1 being mounted on the steering column. Thus in the neutral position shown the two rear lamps 16 and 18 function as stop-lights since the bridge contact 12 connects terminals 4, 5 and 6 together. When the switch 1 is operated to signal a left turn the bridge 14 moves across to interconnect terminals 9, 10 and 6. Lamps 15 and 16 are thereby connected via a resistor and heater wire in the flasher 22, the heater wire causing intermittent closing of contacts (Fig. 6, not shown) to short-circuit the resistor and flash the lamps. Each time the full current flows in the lamps 15, 16 a solenoid in the flasher 22 closes further contacts to connect the pilot lamps to battery. Pilot lamp 33 is opencircuited at terminal 11, however, but pilot lamp 32 is connected by bridge 13 to indicator lamp 17 and therefore lights. The bridge 12 merely connects terminals 4 and 5 in this condition of the switch 1, and thus lamp 18 only acts as a stop light. When the switch is moved to signal a right turn, lamps 17 and 18 are flashed and pilot lamp 33 glows, being in series with lamp 15. If an indicator lamp fails the current through the solenoid in the flasher 22 is not sufficient to close the pilot lamp contacts so the associated pilot lamp does not light. If the failed lamp is a front one the other pilot also will not light when the opposite turn is signalled. In a modification (Fig. 7, not shown) the stop light feature is omitted and front and rear indicator lamps are wired in parallel to a common terminal on the selector switch. In this case if both pilots fail to light it indicates failure of an indicator lamp on each side. If a single indicator lamp only is used on each side to show to both front and rear the flasher 22 must be adjusted so that the pilot contacts close upon full energization of one indicator lamp. Simplified arrangements of the switch contacts are illustrated in Figs. 8 to 11 (not shown).

Abstract: 1,072,386. Shaping filled packages. HOLSTEIN & KAPPERT, MASCHINENFABRIK PHOENIX G.m.b.H. Aug. 5, 1965 [Aug. 11, 1964], No. 33550/65. Heading B8C. A substantially parallelepipedic filled package, shown in continuous lines in Figs. 1, 2 (latter not shown), with rectangular top and bottom walls has side walls which are shaped to be slightly convex with consequent drawing-in of the longitudinal edges, the peripheral length of the walls thus being constant at all horizontal sections. The filled packages are contoured in correspondingly shaped cells. In one embodiment the shaping cell is formed to correspond exactly to the required shape of the cell package, Figs. 3, 4 (not shown), and has flat top and bottom walls attached to shaped side walls (3) which are joined together at the corners (4). In a second embodiment, Figs. 5-7 (not shown), the domed side walls are separate, the walls (12) being connected to the walls (10) by screws (13); the corners of the cells being left open. By adjusting these screws (13) the degree of curvature of two opposite side walls (12) can be adjusted so that production tolerances of the shaping cell and different thicknesses of packaging material can be compensated for. These screws (13) may be locked to standardize the device. Only one side need be adjustable. Shaping cell halves secured on endless chains, the halves being brought together for the shaping operation, may be used on machines in which tubular webs are filled and sealed transversely.
