Title: Energy storing and release mechanism
IPC: B64D1/06
Filed: 1966-10-20
Abstract: 1,108,280. Energy storing mechanism. ELECTRO-SEAL CORPORATION. 20 Oct., 1966 [22 Oct., 1965], No. 47004/66. Heading F2S. [Also in Division F3] An energy storing and release mechanism for actuating a bomb shackle release device comprises a housing 10 defining an elongated chamber 11 having a plunger 50 mounted therein. The plunger 50 is urged outwardly of the chamber 11 by a spring 70 interposed between the plunger 50 and the stator 21 of a solenoid unit 20. The plunger 50 in its cocked position is held against the compressed spring 70 by a locking means which includes a latch 80 pivotally mounted on a forward extension 22 of the stator 21, a detent 82 of the latch engaging a surface 83 of the plunger. The spring 70 acting on the plunger 50 produces a force on the latch 80 tending to pivot the latch away from the plunger so that, to keep the latch 80 in its locking position, a planetary cam assembly 100 is provided. The cam assembly 100 comprises a sleeve (Fig. 7, not shown) mounted on a rotatable shaft 36 and providing an arcuate cam surface over which four cam rollers 110, 111, 112 (113, Fig. 7, not shown) move. The cam rollers are spaced from each other in slots in a spider member 115. The cam roller 110 cooperates with the latch 80 to releasably-hold the same in its plunger locking position. The spider 115 and hence the cam rollers are driven from the shaft 36 through a cam nut 120 which is connected thereto by a set screw 121 so that, with a nut 130 and a washer 131, the position of the cam assembly 100 on the shaft 36 may be varied. The shaft 36 is driven by a rotor 35 which is magnetically coupled to the solenoid unit when the solenoid unit is actuated. The rotation of the rotor 35 is limited by means of a pin-and-slot connection and the rotation of the spider 115 is delayed with respect to the initial rotation of the shaft 36 through a lost motion connection between the cam nut and the spider. The rotor 35 is urged toward its plunger locking position by a spring 34. The underside of the latch 80 is shaped to receive the roller cam 110 and its edge is bevelled at 85 to facilitate release of the latch. The degree of rotation of the spider is also limited by means of a pin 86 depending from the latch working in a slot in the spider.

Filed: 1970-10-08
Abstract: 1327404 Vehicle headlamp SCHICK & CIE 8 Oct 1970 [9 Oct 1969] 47997/70 Heading F4R [Also in Division G1] Vehicle headlamp control apparatus includes a photodetector viewing the area in front of the vehicle and which is sensitive only to wavelengths in a band beyond the red end of the visible spectrum. The headlamps themselves are provided with means to cut out most (about 80%) of the radiation of wavelengths in this band. In this way, the photo-cell responds either to the rear (red) lamps of a vehicle in front, or the headlamps of an oncoming vehicle, but not to radiation from the vehicle's own headlamps reflected back from the vehicle in front or from roadsigns &c. The photodetector may be photoresistive and connected in a transistorized circuit to switch from the high to low beam filaments. The filtering means for the headlamps may be a protective glass having selective transmission by virtue of a thin metallic layer on one of its surfaces, which reflects the unwanted wavelengths. A suitable layer would be a mixture of metal, preferably gold and silicon. Alternatively, a screen having such a layer is mounted behind the protective glass screen. The lamp bulb itself may be coated with such a layer, or be surrounded by a tubular screen having a selectively reflecting layer. Selectively absorbing glasses, incorporating, e.g. lead, may alternatively be used. In another arrangement, the parabolic mirror of the lamp may be treated to be selectively absorbing or non-reflective for the wavelengths in the band to be removed. Reference has been directed by the Comptroller to Specification 1,098,610.

Abstract: 1,192,620. Dyeing acrylonitrile/vinylidene chloride copolymers. HARDMAN & HOLDEN Ltd. 23 Oct., 1968 [24 Oct., 1967], No. 48225/67. Heading D1B. Textile materials comprising fibres of a copolymer of acrylonitrile and vinylidene chloride are dyed or printed by applying a dye liquor or printing paste containing a vat dye and thiourea dioxide as reducing agent, followed by oxidation to regenerate the vat dye in situ. Reduction is preferably effected by heating at 80-110C. and oxidation by alkaline, hydrogen peroxide. The use of emulsions containing trialkyl phosphate or dialkyl phthalate reduces the time for fixation of the leucto dyestuff on the fibres. Vat dye is preferably used as 1-10% by weight and thiourea dioxide as 1-15% by weight of the dyebath or printing paste. In Example 4 a 50:50 blend of polyamide and 80:20 acrylonitrile/vinylidene chloride fibre is printed with good coverage of both fibres.

Abstract: 984, 470. Rewinding record tapes. OMNITRONICS Inc. Dec. 21, 1962 [Jan. 4, 1962], No. 48464/62. Heading G5R. [Also in Division H2] Compliance arms, 17, 18 normally operable over regions B, D, Fig. 1, in association with microswitches 39, 45, Fig. 2 separately to control reel-drive/brake means when transducing a tape moving from reel 14 to reel 13, are switched to operate further microswitches 40, 41, 46, 47 during fast rewind, the arm adjacent the reel currently carrying the greater tape bulk controlling both reel-drive/brake means. This obviates overspeeding of the trailing spool (dotted line, Fig. 6) with consequent overstressing of the tape. Fast rewind switch 66, when operated, energizes a relay K1 to make the additional microswitches operable, and a relay K2 to reverse the motors 15, 16. During the first half of rewinding, full power is fed to motor 16, and since reel 13 is at this time accelerating, drive/brake power may be fed to reel 13 (region C, Fig. 1) to supply the demands of reel 14 according to the arm 17 operating switch 46. During the second half of rewinding, arm 17 remains in the region A, operating switch 47, which then allows switch 41, controlled by arm 18 to control drive/brake power to the reel 16. Instead of switching two reel-motors, one motor with electrically operated clutches connecting drive to the reels may be used (this embodiment is not detailed.)

Abstract: 1,161,787. α-Acids, humulones and isohumulones. BUSH BOAKE ALLEN Ltd. 15 Nov., 1966 [17 Nov., 1965], No. 48866/65. Heading C2C. [Also in Division C6] A bittering additive comprising α-acids substantially free of fixed oils, essential oils and lupulones and a kettle additive comprising lupulones and essential oils substantially free of fixed oils are prepared, the α-acids in the bittering additive are converted into isohumulones, the kettle additive is added to wort and subsequently, e.g. after fermentation, the isomerized bittering additive is added. A solution of a solvent extract of hops in a waterimmiscible solvent, which dissolves alkali metal humulate salts less readily than does water, is contacted with alkali to form a mixture having a final pH sufficient to transfer the α-acids into the aqueous phase as humulate salts but not sufficient to transfer the lupulones into the aqueous phase as lupulate salts, the aqueous phase containing the humulate salts is separated, the humulate salts are subsequently isomerized to give isohumulones substantially free of fixed oils, essential oils and lupulones and, before or after isomerization, the respective humulate or isohumulate salts are separated from a liquid aqueous phase. The hop ingredients remaining in the water-immiscible solvent used in the initial partitioning are recovered after separation from the aqueous phase and freed from any fixed oils and hop waxes by re-dissolving in 80-95% aqueous methanol, whereby there is obtained a kettle additive comprising lupulones and essential oils substantially free of fixed oils. According to one typical example, ground dried hops were extracted and treated according to the above process. The residual aqueous solution of the potassium salts of the humulones was diluted with water to produce a tractable solution containing 30% W/V total solids, was boiled for approximately 45 minutes to effect isomerization and then concentrated by vacuum distillation to a soft extract containing 10-20% of water. The soft extract was dried under vacuum to a dry powdered product containing from 40 to 60% of isohumulones.

Abstract: 1,198,253. Measuring surface profile electrically. RANK ORGANISATION Ltd. Nov. 1, 1967 [Nov.1, 1966], No.49018/66. Heading G1N. In the assessment of one form of surface irregularity, e.g. roughness, waveiness, error of form, distinguished from the others by the frequency band in which it occurs, wherein an electric signal from a sensor 1Z representative of the profile of the surface b is transmitted through a filter 30 to separate out the signals of the chosen frequency range, the time lag introduced into the signal by the filter, which gives rise to an error in the assessment, is removed by feeding the signal in reverse time order through the same or an identical filter. To this end the signal is recorded after the first filtering operation and then read off the record backwards and refiltered. In one embodiment, that illustrated in Fig. 1, the sensor 12 and a recording/replay head 22 are mounted on a threaded rod 10 driven at a constant speed at which a recording drum 20, carrying a layer of magnetizable material, is also rotated. Initially the signal from sensor 12 is fed along path I via switch 36, filter 32 to the recording head 22. At the end of the traverse of the sensor the switch 36 is operated and the rod and drum rotated in the opposite direction, the recorded signal being picked up by head 22 and transmitted along path II via switch 36, filter 34 to a measuring or display device D so that the signal observed corresponds to the instantaneous position of the sensor 12. In a second embodiment, Fig.2 (not shown), the second filter 34 is omitted, the recorded signal being replayed through the same filter (42). The signal may be recorded as a frequency or pulse width modulation of a carrier signal. As an alternative to the magnetic drum recorder, a magnetic tape recorder may be used, Fig. 3 (not shown), or a magnetic disc recorder.
