Abstract: 631,412. Spring clips. REINER, K. July 7, 1947, No. 17890. Convention date, July 24, 1946. [Class 44] [Also in Group XIV] A spring clip e.g. for securing a curl of hair comprises two members having clamping jaws and locating means enabling them to rock one on the other, one of the members having an integral spring tongue engaging the other to urge the jaws together. The lower member 2 has a pair of spurs 10 engaging in sockets 11 in the upper member. Both jaws are slotted at 9, the lower member being cranked at 19 near the end of the slot to form a lip 18 for engagement by the hooked end 17 of the spring bow 16 formed on the member 1. The upper member is bent up at 12 to form spaced finger pieces 13, 14 which are pressed together to open the jaws.

Title: Improvements in or relating to gas-turbine or jet-engines
Inventor: BALLANTYNE DAVID HAVELOCK
IPC: F02C7/26
Filed: 1948-07-02
Abstract: 642,229. Gas turbine plant. ROLLSROYCE, Ltd. July 2, 1948, No. 17909. [Class 110(iii)] [Also in Group XXXV] A gas turbine engine fuel system is provided with an electrically operated valve 29 controlling a bleed 30 from the fuel delivery 26 of the system. The valve 29 is controlled by thermocouples 36, responsive to the temperature of the hot working gases in the engine, through a lowcurrent operated relay 34. When the temperature of the gases exceeds a predetermind value the output of the thermocouples 36 operates the relay 34, closing contacts 34a so that a solenoid 32 associated with the valve 29 is energized, thereby opening the valve to bleed off an amount of fuel from the fuel delivery, thus reducing the temperature of the gases. The control is adapted to operate during the starting of the gas turbine by a starter motor 23. When the motor 23 is energized, by means of a push button 28, a relay coil 35 is also energized so as to connect in series the relay coil 34, thermocouples 36 and a variable resistor 37. After starting the motor 23 and relay coil 35 are de-energized whereby the thermocouples 36 are connected in series only with a temperature indicating gauge 41. The variable resistor 37 serves to adjust the valve of the temperature at which the valve 29 is actuated.

Abstract: 1496438 Luminescent materials PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 May 1975 [6 May 1974] 18431/75 Heading C4S [Also in Division H1] To maintain visible or long wavelength UV emission by phosphors excited by UV of 240 nm. upward from a discharge lamp with reduced requirement for phosphors, the phosphors mixture is applied in two or more layers either on the inner wall of the discharge tube, e.g. in a low pressure Hg lamp or on the inner wall of an outer envelope in, e.g. a high pressure Hg lamp. The layer nearest the discharge contains only phosphors, while deeper layers contain additionally successively higher proportions of a white pigment. The UV specific absorption of the pigment is less than 20% and preferably less than 10% of that of the least absorbent phosphor component. Suitable phosphors for good colour rendering are 1-5 micron grains of Alternatively Mn and Sb activated Ca halophosphates may be used. For the pigment preferably somewhat finer grains of C a P 2 O 7  or BaSO 4  are suitable. In an example with the stratum nearest the discharge containing 3 grams of phosphor and the deeper stratum containing controlled proportions of phosphor and pigment, curves (Fig. 2, not shown) show that compared with a single phosphor layer containing 6À5 grams of phosphor, a slight increase in brightness is achieved with, e.g. only 5 grams of total phosphor (2 gm. in deeper layer) and 4À5 grams of pigment. Beyond 6 grams of pigment adhesion fails.

In a liquid-ring vacuum pump, the control disc 1, Fig. 4, has upstream of the pressure port 2 a number of perforations 3 covered by a flexible plate 7 located by guides 8b. The plate acts as a non-return valve to permit gas to flow through the perforations to the discharge chamber in the event of over-compression, and resist return flow to the working chamber in the event of undercompression. The plate may be of corrosionresistant metal, e.g. non-rusting steel, or a synthetic plastics material which inhibits the deposition of impurities, e. g. polytetrafluoroethylene. In a known pump, Figs. 1 and 2 (not shown), the perforations are each associated with a ball-type non-return valve.

Filed: 1916-12-30
Abstract: 110,836. Steven, J. A. and Gotterson, R. J. Dec. 30, 1916. Electric braking; systems for alternating - current motors only.-A polyphase motor control system consists of a distant control switch controlling two electro-magnetic reversing switches, an electro-magnetic resistance-controlling switch, an electro-magnetic braking- resistance switch, and the coil of a band brake; and a speedoperated switch and a direction-operated switch are provided and so arranged that the motor cannot be controlled to effect reversal until it is stopped or nearly stopped. In the arrangement shown in Fig. 1, the reversing switch magnets 2, 3 and the magnet 10 of the starting resistance 6 are controlled bv a distant switch 1. When the switch 1 is operated to energize the magnet 2, the following circuit is made-lead 8, magnet 2, left hand contacts of switch 1, magnet 10, contacts 17, 12 of speed-operated switch, and bridge 14 of magnet 10 to lead 9. The main switch operated by the magnet 2 is closed, the bridge 19, Figs. 1 and 2, is lowered through a dash-pot 4, the switch 10<1> controlling the starting resistance 6 is closed, and the bridge 14 raised. The closure of the main switch energizes the magnet 5 connected to a switch controlling the dynamo braking resistance 11 as followslead 23, contact o, lead f, contact P, lead F, magnet 5, leads E, D, bridge 19 in its lower position, lead C, bridge 22, leads B, A, contact P', lead f<1>, contact o', and lead 8. The coils 15 of a band-brake also are energized through the bridge 14 in its upper position. When the switch 1 is moved to its inoperative position to stop the motor, the magnets 2, 10 are de-energized and the magnet 3 energized as follows-leads 8, g, magnet 3, lead g<1>, bridge 19 in its upper position, lead h, direction switch 20, magnet 21, contacts 18, 12 of speed switch, lead h<1>, and bridge 14 in its lower position to lead 9. Under this condition the switch 3 is not sufficiently energized to operate its main switch, while the energization of the magnet 21 raises the bridge 22 to open the circuit of the magnet 5 thereby introducing the braking resistance 11 into the motor circuit. The band brake is also applied by the de-energization of the coils 15 by the lowering of the bridge 14. To reverse the direction of rotation of the motor, the switch 1 is operated to energize the magnet 3.

The strip of rubber is now wrapped round the top part of the ring 19 and then slipped downwardly to between the two rings. A pressure ring 23 is placed between rings 18, 19, and pushed axially to force the ring 17 into a space 16 during which the ring is radially compressed.

The ring 17 may have co-operating ridges formed thereon. A lubricant, which is either absorbed into the rubber after assembly or becomes an adhesive after assembly, may be used to facilitate assembling the damper.
