Title: Improvements in and relating to electrical variable impedance device
Inventor: ASPDEN HAROLD
IPC: H01F29/14
Filed: 1956-04-18
Abstract: 855,907. Magnetic amplifiers. ENGLISH ELECTRIC CO. Ltd. July 17, 1957 [April 18, 1956], No. 11836/56. Class 40 (9). [Also in Groups XXXV and XL (c)] A cross-field variable inductor comprises a magnetic core having a part 10a which is subjected to a saturating field due to a polarizing winding 12 which is crossed by a field due to an A.C. winding 11, the currents through the windings being proportional. In a certain range of saturation the inductance L of the A.C. winding is inversely proportional to the polarizing current so that the device may be used in a voltage stabilizer (Fig. 8). In that Figure an A.C. winding 52 is connected in series with a polarizing winding 51 fed through a full-wave rectifier 53 and filter 54. Since the current i through winding 52 is the polarizing current and the inductance of winding 52 is inversely proportional to this current, the product Li is constant and hence the voltage across winding 52 is constant at constant frequency. The Provisional Specification also discloses an automatic tuning control (Fig. 9) and a frequency doubling circuit (Fig. 10). In Fig. 9 in order that the circuit 62, 63 should resonate for any of a range of frequencies the inductance of winding 62 must be given by L = K/w<SP>2</SP> where w is the frequency and hence I the polarizing current must be proportional to w<SP>2</SP>, i.e. proportional to 2ww 0 -w 0 <SP>2</SP> where w 0  is a fixed frequency in the range. Hence a first polarizing winding 61a is fed from a voltage source E with a voltage p<SP>2</SP>E corresponding with a current proportional to w 0 <SP>2</SP> and a winding 61b is oppositely fed with a voltage dependent on the frequency w derived from a resistor 65 through a device 67 as in Fig. 8 above, and on pE so as to correspond with 2ww 0 . The factor p is determined by sliders of three ganged potentiometers such that a different p provides a different w 0 . Fig. 10 discloses a frequency doubling circuit in which the variable inductance winding 72 is in series with a resistor 73 and is fed from a source E sin wt. Two polarizing windings are provided carrying currents I o  and I 0  sin wt. Since L α K/I the current through the winding 72 comprises two components one of frequency w and the other of frequency 2w, the former being filtered out by a capacitance 74 and the output voltage being obtained across resistor 73. Various constructional forms of the impedance device are disclosed in the Provisional Specification also. Specification 841,866 is referred to.

Title: Seat belt safety systems
IPC: B60R22/48
Filed: 1971-04-28
Abstract: 1380062 Controlling vehicles JAGUAR CARS Ltd 18 April 1972 [28 April 1971] 11873/71 Heading B7H  In a motor vehicle safety system in which the starting of the vehicle is inhibited unless all occupied seats have their associated seat belts fastened and the gear selector is in the "neutral" position, the ignition system is allowed to function even when an occupied seat has its associated set belt unfastened. As shown in Fig. 1, normally closed pressure sensitive switches 1, 2 and normally open seat belt switches 3, 4 are associated with two of the vehicle seats. Switches 5 and 6 are closed when the gear selector is placed in the neutral or drive position respectively. Assuming only,the driver enters the vehicle, the ignition switch 10 is turned on supplying current to the ignition coil 20 and also to line 13. Switch 1 will be opened by the driver being seated and switch 3 closed when the seat belt is locked thus providing a current flow via closed switch 2 to coil 16 which controls solenoid switch 7. Thus switch 7a is closed and 7b open and providing the gear selector is in neutral, i.e. switch 5 is closed, the circuit to starter motor 8 will thus be made. If seat belt switch 3 is open, however, switch 7b will remain closed and, the alarm 9 will be energized providing the gear selector is in drive, i.e. switch 6 is closed. In a modification, Fig. 2 (not shown), provision is made to ensure that a passenger unlatches and refastens a seat belt which has already been fastened in an unoccupied seat. A time-delay device could be incorporated to ensure that the above operation does not come into effect after say three minutes to enable the driver to turn the ignition off, to read a map for example, without having to unlatch his seat belt for starting.

Patent GB-396011-A (GB)
Title: Manufacture of 3-oxyselenonaphthene and its derivatives
Filed: 1933-04-26
Abstract: 3-Oxyselenonaphthenes are prepared by reacting potassium cyanide and selenium with a diazotized ester of an anthranilic acid, saponifying, treating the product with monochloracetic acid, and converting the product to the oxyselenonaphthene by boiling with acetic anhydride followed by saponification.  An example illustrates the treatment of anthranilic acid methyl ester to give 3-oxyselenonaphthene. Reference is made to the production of oxyselenonaphthenes substituted by alkyl, aryl, halogen, amino, substituted amino (acylamino, alkylamino), hydroxy, alkoxy or sulpho groups by starting from the correspondingly substituted anthranilic acid.  The introduction of selenium is facilitated by the process as compared with the known process of treating diazotized anthranilic acid with alkali hydroselenide.

Title: Improvements relating to bucket grabs
IPC: B66C3/06
Filed: 1941-09-22
Abstract: 549,274. Bucket grabs. CAULFIELD, W. J., and WESTWOOD & CO., Ltd., J. Sept. 22, 1941, No. 12264. [Class 78 (iv)] Relates to bucket grabs of the type in which the buckets are pivotally connected to a beam 5 which in the closing and opening movements respectively of the buckets is raised and lowered toward and away from a head 4 from which a system of chain, rope &c. purchase blocks 2 depends for connection of the lower blocks 3 to the beam 5 during the operation of closing the buckets, the purchase gear being employed during that operation to raise the beam 5 and thereby close the buckets, and there being between the lower blocks 3 of the gear and the beam 5 a coupling which is engageable automatically upon the nearing of the blocks 3 to the beam 5 and is disengageable (a) by hand when the grab is in mid-air, or (b) automatically upon the grab being lowered on to the dump. The coupling comprises a link 14 on the beam 5 which, when the coupling is engaged and under load, interlocks by a projection 17 on the link with a dog 18 pivoted to the lower block 3, and which is pushed aside by the dog as the latter, during the approach of the block 3 to the beam 5 moves past the projection 17 to lock therewith. The dog 18 is prevented from swinging under the action of the load by a pin 25 on a pivoted detent 27, which pin engages an upright 20 on the dog 18. The projection 17 bears on the supporting surface 21 of the dog 18 at a point slightly out of line with the vertical through the pivots of the link 14 and dog 18, thus permitting the projection 17 to slip off as soon as the detent 27 is pulled down by a cord 28 from the cabin or ground, this being assisted, if necessary, by a kick from the detent 27 on the arm 20 as soon as the pin 25 has risen clear thereof. Automatic release when the grab rests on the dump is effected by a sliding weight 34 which bears on the detent 27 and frees the pin 25 from the dog 18. Pull on the lifting cable 1 then raises the block 3 and the buckets open as the grab is raised. A small amount of lost motion is allowed between the connected block 3 and the beam 5 to permit of this. Balance weights 30, 33, 35, or springs, restore the various parts to re-engaging position.

Title: Improvements in coin mechanism for coin freed or actuated machines
Filed: 1919-05-20
Abstract: 149,777. Richards, G. L. May 20, 1919. Testing coins; diverting improper coins. -Apparatus for separating coins having apertures from those without and for segregating coins of incorrect size comprises a shoot in one part of which the coin runs on its edge and in another part slides on its face, so as to allow the coin to be engaged by a device for temporarily arresting coins with apertures for a longer period than those without. The first section of the shoot is arranged obliquely and comprises a lower rail 4 on which the coin rolls, a back wall 5 and a front wall 6 followed by a low ledge 7. The rail 4 terminates in an abutment 8 in advance of which is a gap 9 in the rear wall, a flange 10 being left. Behind the gap is a section 11 the floor of which is parallel to the section 4 and at its termination has an upstanding tongue 16 beyond which extend wings 14. A third section of the shoot is constituted by a downwardly inclined but not oblique surface 15 with flanges 16 and a raised cross piece 17 slightly lower than the surface 11. In front of the curved end wall 18 of the shoot is an aperture 19 through which a coin passes on to a disk 20 having an upstanding pin 21 and adjustably balanced on bearings 22 by a weight 24. A coin having a hole of correct diameter tilts over the flange 10, passes over the tongue 13. and, falling on to the balance 20. tilts it until allowed to drop off the pin 21. A coin without a hole is retained on the balance for a shorter period and is thus diverted to a different destination. A coin having too large a hole will be arrested by the tongue 13, and the operater will then press a spring-controlled bar 26 which acts through levers 27, 28, a rod 29, lever 30, and shaft 31 to raise throw-out segments, which operate through slots 33 to return the coin. Gaps 35, 36 are provided in the walls 5, 6, the rear gap 35 allowing undersized coins to fall through, and the front gap serving for the ejectment of coins that stick in the shoot; these are operated on by an arm 41 mounted on a shaft 40 rotated by the operation of the bar 26 through connexions 37, 38. A magnetized rod 42 extending into the surface of the shoot is provided to arrest disks of magnetic metal.
