Patent GB-2128714-A (GB)
Title: Fibre-reinforced-plastics springs
Inventor: WARD TERENCE HENRY
IPC: B60G11/113
Filed: 1983-10-13
Abstract: A leaf spring assembly has one or more spring leaves 1,2 of fibre reinforced resin material. Such springs have failed in the past due to a sudden transition in the spring between flexibility and rigidity at a region where a load applying member is secured to the spring. A load is transmitted to the leaf 2 from, for example, a vehicle axle 15 via an elongate member 5 whose upper surface is shaped to conform to the deflected shape when loaded of the leaf 2. Member 5 supports the leaf at this region. A flexible layer of, for example, polyurethane may be interposed between member 5 and leaf 2 to facilitate an even transfer and distribution of load. Similar layers 3, 6 may be provided below and above leaf 1 and a spring steel strip 7 on layer 6. A bolt 9 secures components 5,4,2,3,1,6 and 7 together and the whole is secured to axle 15 by a rigid plate 8 and U bolts 16. <IMAGE>

Title: Plug-in thermostat
Inventor: SPENCER VICTOR JOHN
IPC: H01R13/713
Filed: 1983-12-16
Abstract: A plug-in thermostat for a heating appliance comprises a body (10) having pins (12) for plugging into an electric socket, its own socket (20) by which the heater appliance may be plugged in, and thermostat contacts (3) controlled by manually adjustable setting means (4). Accelerated heating of the thermostat contacts (3) is effected without dedicated components by arranging the thermostat contacts over said socket, whereby heat emanating and rising from the socket in use provides the main source of heat for accelerated heating. Vents (15, 17) allow an upward convective draught of said heat to play on the contacts (3). Where the thermostat has a load indicator circuit, comprising a neon indicator (6) and a resistance (9) connected in series, said resistance may be arranged near the contacts to supplement the heat emanating from said socket. <IMAGE>

IPC: G10D1/12
Filed: 1984-04-12
Abstract: A dulcimer playing a range encompassing several octaves of semitone scale, the scale of which is arranged in an order more convenient for the performer. The dulcimer comprises a soundboard (14) on which five rows of bridge members (21, 22, 23, 24, 25) are positioned, between which a corresponding number of string elements (81, 82, 83, 84, 85) are stretched over the soundboard (14) and tempered to produce desired tones, in which the strings playing treble tones, having lengths less than the width of the soundboard (14), are held at one end thereof on the string holders (50, 52) secured intermediately in the soundboard (14), the remaining strings being stretched over the soundboard (14) and having both ends held by the wrest pins secured on the two inclined side plates (12, 13) of the soundboard (14). The arrangement of the string elements varied in tones is that the strings producing treble tones are arranged on the left side relative to those producing bass tones; the semitone strings are gathered in an upper area on the soundboard; each string produces a note a major second above the next string; and the left section and right section of a string element viewing from the bridge member playing tones wherein the former is a perfect fifth above the latter. <IMAGE>

Title: Modified vinyl chloride resins
Inventor: KAUFFMAN WILLIAM JOSEPH
IPC: C08L1/00
Filed: 1984-04-26
Abstract: A process for treating plastisol-type vinyl chloride resins having small particle size and relatively little capability for absorbing plasticizers such that the plastisol absorbing capabilities of the resins are improved.

Title: Valve for ink marking systems
Inventor: ARWAY GEORGE
IPC: F16K7/17
Filed: 1984-10-02
Abstract: A valve 35 for use in an ink marking system has an output port 48 and a supply port 46, located below a flexible diaphragm 44 and a control port 38 which communicates with a chamber disposed above the diaphragm. The diaphragm flexes between an open position permitting the supply port to communicate with the output port and a closed position blocking such communication, as a function of the pressure differential across the diaphragm created by pressure changes at the control port. In use in the system, a three-way valve 52 under the control of a detector 30 connects the output port 48 to vacuum source 22, and connects control port 38 either to atmosphere to close the valve 35, or to vacuum source 22 to open the valve so that fluid flows from a supply container 32 connected to the supply port 46 through output port 48 to an ink reservoir 14 for a print head. <IMAGE>

Title: Method for promoting disulfide bond formation in recombinant proteins
Inventor: KOTHS KIRSTON EDWARD
IPC: C07K14/565
Filed: 1985-11-13
Abstract: Reduced cysteine-containing proteins consisting of recombinant IFN-β, IL-2 muteins thereof may be oxidized selectively so that the recombinant proteins have essentially the same disulfide bridging and biological activity as their native counterparts. The oxidized product is substantially free of unwanted side products and contains a minimal amount of intermolecular oligomers. The oxidation takes place in an aqueous medium containing a solubilizing agent at a pH of about 5.5 to 9, preferably at a pH of about 7. The reaction is initiated by addition of at least an effective amount of an oxidation promoter containing a Cu<sup>+2</sup> cation such as CuCI<sub>2</sub> or o-phenanthroline/Cu<sup>+2</sup> complex in the presence of air.

Title: Casings for flexible drive shafts
Inventor: TAYLOR KENNETH WILLIAM JAMES
IPC: F16C1/26
Filed: 1986-01-22
Abstract: An end member, e.g. a ferrule 1, is attached to the end of a helically wound flexible casing 4, e.g. of a helically wound flexible drive shaft 3, by inserting the end of the casing as a tight friction fit in a bore 8 in the ferrule 1, and rotating the ferrule relative to the casing. This causes the casing to contract slightly thereby permitting the ferrule to be threaded thereon. The helical thread of the ferrule forms a self-cutting, self-locking thread which prevents the end member from being unscrewed. <IMAGE>

Patent GB-2182185-A (GB)
Title: Image forming apparatus
Inventor: ONODA SHIGEYOSHI
IPC: G03G15/00
Filed: 1986-09-30
Abstract: This invention prevents inconvenient phenomena from being caused by an image forming operation starting signal being generated by mistake to thereby start the image forming operation when an image forming apparatus is not in its normal installed state for use, for example, when the apparatus is in its carried state or its erected state with one side thereof facing downward. As shown, the apparatus is in its erected state in which a weight 35 acts on a lever 31 to block a photointerrupter 32. If this remains blocked for a given time period, a control unit 36 operates to inhibit operation of the machine. In other embodiments, the apparatus is inhibited if a carrying handle is moved to its carrying position or if a paper supply tray is in a non-operative position or if a handle portion of an original pressing plate is in a given position.
