Patent GB-1459676-A (GB)
Title: Reference voltage source
IPC: G05F1/46
Filed: 1974-03-22
Abstract: 1459676 Automatic voltage regulation ROBERT BOSCH GmbH 22 March 1974 [23 March 1973] 12808/74 Headings G3R and G3X A reference voltage circuit includes a first current branch comprising one or more series-connected Zener diodes, and a parallel second branch including two voltage-dividing resistors and at least one series diode. The reference voltage is taken across the mid-point of the two resistors and one of the junctions of the branches. The numbers of Zener diodes and diodes in the circuit are chosen in relation to other circuit parameters such that the temperature coefficient of the reference voltage is independent of the value of the Zener breakdown voltage produced during manufacture. The voltage divider ratio is adjusted to give a predetermined output voltage at a given temperature. As shown in Fig. 1, the circuit may include k Zener diodes and groups of /, m and n diodes. Preferably, in the case of circuit manufacture using silicon, the numbers are chosen such that m + n -l = 2k, thus satisfying the required condition for diode currents of 1 ma. Circuits fulfilling this criterion are described with reference to Figs. 2-11 (not shown) and may include a transistor or operational amplifier. The ratio of resistors R1, R2 determines the temperature coefficient of the output voltage U1, and may be adjusted by using potentiometers, modifying layer resistors using a sand jet, laser beam or etchant, or by shortcircuiting components of resistors in a monolithic integrated circuit. The reference voltage circuit may be used in a regulated supply arrangement, Fig. 16, including a series transistor T4 controlled by a differential amplifier T2, T3.

Title: Improved elastic joint and method of manufacturing of the same
IPC: F16F1/36
Filed: 1936-05-07
Abstract: In a joint of the kind comprising a mass of rubber maintained in a state of initial deformation between two rigid members (for example, a rubber bush between concentric metal sleeves), the rubber is caused to adhere to one or each of the rigid members by the interposition of a layer of imperfectly-vulcanized rubber, which will become cemented to the mass of rubber by chemical action due to hysteretic heat or may be attached by a suitable adhesive.  The layer of imperfectly-vulcanized rubber may be deposited on the rigid member electrolytically, in solution, or in a sheet, and may be secured by cement or by preliminary coating of the rigid member with brass; it may also be secured by hot vulcanization to a layer of ebonite, secured to the rigid member by grooves or the like, or of latex.  The surface of the rigid member may be rough or smooth.

Abstract: 1323665 Forcing liquids by heating N J M BOLIN 5 May 1971 [5 May 1970] 13219/71 Heading F1R [Also in Division F4] A water or other liquid boiler comprises an outer shell 1 for the liquid, an insulated inner shell 4 closed at its upper end and communicating at its lower end with the liquid in the outer shell, and means 6 for heating the liquid in the inner shell to produce vapour 9 at the closed end thereof sufficient to effect circulation of liquid through the boiler. In a central heating system the return flow of water enters the boiler at 2 and the hot water is discharged through outlet 3 having a check valve 8. The inner shell 4 is surrounded by insulation 7 encased in a cylinder 7; alternatively the cylinder 7 may be omitted or an air gap or combination of insulation and air gap may be used. During heating of tube 5 by gas burner 6, the water in the inner shell produces steam at 9 whose pressure causes check valve 8 to open and discharge hot water through outlet 3. The fall in the water level within the inner shell causes condensation of steam with resulting drop in pressure thus drawing further water into the boiler through inlet conduit 2 which may alternatively be connected directly into the inner shell. In another embodiment Fig. 2 (not shown) an electric heating element (10) is used instead of the burner. The boiler may have have a plurality of inlet and outlet conduits and gas burners or heating elements.

Abstract: 1,039,076. Turbines. LINDE A.G. March 30, 1965 [April 15, 1964], No. 13355/65. Heading FIT. In a nozzle ring for a single or multi-stage, axial or radial-flow expansion turbine having means for varying the admission arc, the flow rate through the ring per unit of circumferential length thereof is non-uniform. A nozzle ring for a centripetal radial-flow turbine is divided into two sectors. Sector 2, Fig. 1 (not shown), extends over 30 per cent of the circumference and provides about double the throughput of sector 1 per unit length of circumference. The regulating means is associated with the nozzles 5 of the sector 2, so that flow through only a relatively small arc is controlled and the consequential ventilation losses are low. In sector 1 there are twenty-eight nozzles the blades 4 of which are set at an angle of 15 degrees. In sector 2 there are nine nozzles the blades 6 of which are set at an angle of 27 degrees. Special nozzles 7, 8 which take into account the change in blade angle are provided at the transitional points of the sectors The blades in sector 2 may be of greater axial length than those in sector 1.

The device 5 consists of a support member 14 and spaced arms 15 to each of which is secured a sharpening element 17 of tungsten carbide or abrasive material. Each arm is formed with a groove 21 to provide resiliency so that the arms, and thus the elements 17, can be moved apart as a knife blade is moved between the elements. The support member 14 is mounted by a pivot to the carrier 6 to positions determined by engagement of a resilient flange 23 with stops 24, 25. In another embodiment, the sharpening elements 117, Fig. 5, and support element 114 are formed from a single piece of resilient metal. In further embodiments, the sharpening elements are in the form of overlapping discs, and the carrier is arranged for linear movement.

The inner sleeve 4 may also have tensionresistant reinforcing material embedded therein. The bag of Figs. 1 and 2 has three cells 7 and is provided with metal fittings 8 enabling the connection of chains to suspend the bag from a dock wall to act as a fender (Fig. 3, not shown). A plurality of interconnected bags may alternatively be used to form a dock fender (Fig. 4, not shown). Fig. 7 illustrates a bag with-two gas-filled cells 7 in use as a buffer between barges L1, L2. A pair of two-cell bags may be connected to a plate (12) to form a float for supporting a dredging pipe (Fig. 9, not shown). The bag may be made by coating the inner sleeve 4 with a release agent in the regions where it is not to be joined to the outer sleeve, forming the outer sleeve around the inner sleeve, and then vulcanizing the assembly to form the joints 5. The inner sleeve may be supported on a cylindrical metal former, or may be in flat form, during manufacture.

An electric motor drives the roller through variable speed gearing, the speed being gradually increased to secure a uniform layer on the surface of the roller, which is finally rotated in air for a few minutes. The drawing on transparent paper or a transparent positive of it is applied to the roller, the edges being joined by a gelatine strip, and exposed to the light of quartz lamp through a slit in a screen before which it rotates. The drawing is removed and the roller rotated in dilute alkali to remove the unexposed albumen. It is then treated with bitumen, dried, and etched. For a stronger impression Palestine bitumen in turpentine may be used for the sensitive layer, or the roller may be reinforced by varnishing the protected parts with a paste of this compound and further etched.
