Title: Improvements in electrical terminal connections
IPC: H01R43/033
Filed: 1960-07-08
Abstract: 906,567. Wrapping wire on terminals. STANDARD TELEPHONES & CABLES Ltd. July 8, 1960 [July 15, 1959], No. 23949/60. Class 83 (4). [Also in Group XXXVI] A terminal connection is made by wrapping a wire 4 insulated with polyvinyl chloride, or a similar soft resilient plastics insulating material, around a terminal post 1 having sharp edges under such tension that the edges cut through the insulation and embed themselves in the wire. Stripping insulation from the wire is thus avoided, equally for single-ended attachment and for joining a terminal post at some distance along a wire as shown in Fig. 3. A wrapping tool, Figs. 9-11, has a stationary hollow sleeve 11, secured by bolt 12 to hand-grip 10, slotted at 13 to receive the edge of the strip of insulation (not shown) holding the terminal post 1. Insulated wire 24 passes through a hollow bit driver 17, fastened in rotating hand-grip 16, down hollow stem 20 into a surface axial slot 21 of bit 15 which is counterbored at 19 to take the terminal post 1. In operation the end of wire 24 is held firmly under slot 13 and hand-grip 16 rotated sufficiently to wind six or seven turns of wire on the post. The radius of the wrapping bit is initially adjusted by trial and error to obtain the correct tension in the wire. Specification 674,709 is referred to.

Title: Improvements in or relating to writing instruments
IPC: B43K24/08
Filed: 1956-08-03
Abstract: 854,313. Writing instruments. KAHN Inc., D. Aug. 3, 1956 [Aug. 30, 1955], No. 23993/56. Class 146(3). A retractable writing instrument, e.g. a ball point pen, comprises a plunger 30 non- rotatably mounted in the barrel, an axially displaceable and rotatable member 40 whose axial position determines the axial position of the cartridge unit, and a spring 24 which urges the member 40 towards the plunger, the member 40 and the interior of the barrel being formed with coacting members which interengage in different axial positions depending upon their relative rotational adjustment, depression of the plunger 30 partially rotating the member 40 to effect such adjustment. The plunger 30 has at its upper end radial lugs 33 with downwardly projecting teeth 34. The member 40 has at its lower end, as shown in Fig. 1, radial lugs 42 of greater diameter than the lugs 33 and formed at their upper edges with inclined surfaces 42a. A series of longitudinally extending alternately deep and shallow grooves 52, 53 is formed in a barrel part 13, the grooves having teeth 51 adjacent to their lower ends. The upper part of the member 40 is rotatably received in a recess in the plunger 30 so that the teeth 34 can engage the inclined surfaces of the lug, 42 and the inner end of the pen unit 20 fits within a recess 41 in the member 40. The grooves 52, 53 are of such dimensions that the lugs 33 can enter all the grooves but the lugs 42 can enter the deeper grooves 52 only. In retracted position the lugs 33 are at the upper ends of the grooves 52, 53, there being one lug 33 for each groove, and the lugs 42 are, in the deep grooves 52 bearing against the opposed teeth 34, there being one lug 42 for each deep groove. When the plunger 30 is depressed, the member 40 moves downwardly and the pen point is projected ; during this movement the engagement of the teeth 34 with the inclined surfaces 42a tends to rotate the member 40 and in fact rotation takes place when the lugs 42 clear the bottoms of the grooves 52. Upon release of the plunger 30 the surfaces 42a engage the teeth 51 and such engagement under the action of the retracting spring 24 causes the parts 40 to rotate further until it abuts against the side 51a of the next tooth 51. The writing unit 20 is thus latched in projected position since the lugs 42 cannot enter the intermediate shallow grooves 53. When the plunger 30 is again depressed a similar action occurs but the lugs 42 are displaced into alignment with the deep grooves and the parts return to retracted position under the action of the spring 24. Reference has been directed by the Comptroller to Specification 748,897.

Title: Improvements in or relating to a method and an apparatus for applying a heat shrinkable sleeve to a roll
IPC: F16C13/00
Filed: 1967-05-23
Abstract: 1,136,866. Rollers. RAYBESTOS-MANHATTON Inc. 23 May, 1967 [12 Aug., 1966], No. 23993/67. Heading F2U. A heat-shrinkable plastics sleeve is attached to a roll 10, e.g. a metal cored silicone rubber roll used as a " fuser " roll in xerography, by applying the loose sleeve to the roll, supporting the whole vertically on a vertically-reciprocable and rotatable table 20, and heating the roll by two hot air blowers 34, 36 connected to a plenum ring 38 surrounding the roll, whilst the roll is first lowered and then raised. The sleeve may be formed of P.T.F.E. and may be preconditioned on manufacture by heating and expanding, and then cooling in its expanded condition. It may also be additionally attached to the roll by a silicone resin adhesive, the sleeve being preliminarily etched to aid the adhesive. As shown, the table 20 carrying the roll 10 is mounted on a reciprocating platform 50, guided by rods 52, and carrying a motor 26 which rotates the table. A double acting air operated piston and cylinder 24 is operated to raise and lower the platform 50 by means of the piston-rod 48 fast with the motor casing 64, an adjustable knob 74 on the casing 64 abutting a valve 76 to reverse the direction of motion of the platform 50 when it reaches its lowest point. Descent of the platform is initiated by a manual control 70. The plastics sleeve is formed longer than the roll which has tapered ends, Fig. 4 (not shown), and the valve system controlling the piston and cylinder 24 is adapted to delay the motion of the platform 50 at its limits of movement to accommodate the extra heating, and hence shrinkage, required. The descent of the table 20 may take 50 sees., the ascent 20 secs., and the delay at each end of its motion 20 sees.

Abstract: 836,022. Electric analogue calculating. COLLINS RADIO CO. Aug. 3, 1956, No. 24041/56. Class 37. In a computer for determining the distance D 3  and bearing # 3  of a fixed point B (Fig. 3) from a moving point C (e.g. an aircraft) in terms of the distance and bearing D 1 , # 1 , and D 2'  # 2  of the aircraft and of the fixed point from a reference station A; potentiometers R 1 , R 2  (Fig. 2) are energized from a 400 c.p.s. power source of unstable frequency and a local oscillator 33 of stable (e.g. crystal controlled) and widely differing frequency coupled over transformer 35. The potentiometer sliders are manually or servo adjusted in response to respective distances D 1 , D 2  and energize resolvers 12, 18 having single primaries 11, 19 coupled to quadrature secondaries 13, 14; 20, 21; the angular relation between the windings being determined by manual or servo adjutment to the bearings # 1 , # 2 . Voltages across windings 13, 14, 20, 21 representing respectively X 1 , Y 1 , X 2 , Y 2 ; the Cartesian coordinates of points C and B referred to point A; are additively combined in appropriate phase senses to derive voltages representing [X 1 +X 2 ] and [Y 1 +Y 2 ], which energize the quadrature primary windings 25, 26 of a third resolver 24 having quadrature secondary windings 28, 29; the angular relation between the pairs of windings being determined by manual adjustment of knob 30. The voltage appearing in the horizontal winding (containing components both at 400 c.p.s. and the frequency of oscillator 33) is connected to a measuring instrument (not shown) while the voltage in the vertical winding is freed from 400 c.p.s. components in filter 37 and applied to a phase detector 31 also receiving a comparison signal from oscillator 33 to produce a unidirectional phase difference signal indicated by centre-zero instrument 32. Knob 30 is rotated until the instrument reads zero, at which the rotational angle thereof indicates the bearing # 3  of point B from point-C, and the voltage from winding 28 indicates the distance D3. Since a null indication is produced only for the signal from stable oscillator 33, errors due to fluctuations of the 400 c.p.s. frequency source and consequent quadrature voltages in the system are removed, while the power absorbed by the instruments responsive to the D 3  voltage is supplied from the 400 c.p.s. source.

Patent GB-393307-A (GB)
Title: Recovery of sulphur
IPC: C01B17/06
Filed: 1931-08-28
Abstract: Sulphur is recovered from pyrites or other iron sulphide by the action of sulphur dioxide in the presence of one or more of the following metal compounds containing oxygen, magnesium oxide, sulphite, sulphate or carbonate, calcium oxide or sulphite, ferric or aluminium oxide, the products being elemental sulphur and ferric oxide.  Preferably the materials are used in finely divided form and the materials may be moistened with water and formed into small lumps or aggregates.  When using magnesium compounds, these are present in not less than 20 per cent calculated as oxide, calcium, as oxide, being not less than 15 per cent.  The temperatures employed lie between 600 and 800 DEG  C. and the sulphur dioxide may be diluted with other gases containing no free oxygen. In one method of operation, a mixture of pyrites and magnesium oxide is introduced into one end of an internally or externally heated rotary reaction chamber, sulphur dioxide being supplied at the other.  The temperature is maintained at 600-650 DEG  C. and the sulphur vapour is removed near the charging end.  To recover the magnesium oxide, the hot residue is subjected to an air separation.  In an alternative method, the sulphur dioxide is produced by admitting air at the discharging end to react with some of the ferrous sulphide formed by the removal of the labile sulphur atom, the amount of air being so controlled that the iron is converted to ferric oxide and the sulphur discharged in the elemental form.  The magnesium oxide constitutes 25 per cent of the mixture which is preheated to 700 DEG  C.  Instead of mixing the magnesium oxide with the pyrites, it may be blown in with the air supply.
