Title: Dyeing and finishing cellulose materials
Filed: 1960-11-16
Abstract: Cellulose materials, such as textiles, films or paper, are dyed and given an anti-crease finish by applying simultaneously, under alkaline conditions, a dyestuff reactive with the cellulose under alkaline conditions and an anti-crease agent also reactive with the cellulose under alkaline conditions.  Suitable dyestuffs are those of the nitro, azo, vat, triphenylmethane, phthalocyamine and anthraquinone series containing, as the reactive group, a cyanuryl halide, a substituted or unsubstituted vinyl sulphone, a pyrimidyl halide, a b -halogenopropioxyl, a b -halogenoethylsulphonyl, a b -halogenoethylsulphamyl, a b -sulphatoethylsulphonyl, a b -hydroxyethylsulphonyl, a chloroacetylamino, a b -(chloromethyl)-b -sulphatoethyl sulphamyl, an alkyl phosphite or a sulphonofluoride group.  The anti-crease agent may be resinous or non-resinous and specified examples are methylol ureas, methylated methylol ureas, melamineformaldehyde, phenyl-formaldehyde and ketoneformaldehyde condensation products, divinyl sulphone and various di (2-hydroxyalkyl) sulphoxo compounds, methylene-bis-acrylamide, vinyl cyclohexene dioxide and various polyglycidyl ethers of polyhydric alcohols.  The dyestuff and anti-crease agent are applied from a common aqueous bath together with an alkali, such as an alkali metal hydroxide, carbonate or bicarbonate, trisodium phosphate, sodium silicate, ammonium hydroxide or a quaternary ammonium hydroxide, at a temperature up to 180 DEG F.  The treated material is dried and then heated at 220 DEG -400 DEG F.  The dyestuff may also react with the anti-crease agent.  Examples are given.

In an exchange containing a memory in which the addresses of busy subscribers are stored, tests for double connections are made by comparing the addresses stored with each possible address in turn, and giving an indication if two successful comparisons occur for any such address. In the time division multiplex system shown, at a pulse phase allocated to a connection, the address of the calling subscriber is stored in Ua and that of the called subscriber in Ub, the latter being accompanied by storage of a switch-through pulse of the same phase in UDB. Generator G emits subscribers' addresses in turn, each for the duration of one multiplex cycle, and these are compared at Va, Vb with addresses present at any phase in Ua, Ub. If the subscriber's address is present in Ua or Ub the comparator output pulse passes to or-gate GV, unconditionally in the former case, and also in the latter case if the pulse occurs simultaneously in UDB. If a double connection exists two differently phased pulses will arrive at GV. The first operates trigger V which after a short delay enables one input of gate ADV. On the arrival of the second pulse the second input of ADV is also enabled and this operates trigger DV, which operates trigger SLP via a gate GLP which may be inhibited if a trunkoffering condition is present. Trigger SLP which indicates an unwanted double connection may open gate LP to pass pulses in the respective phases, but delayed at T for the duration of one multiplex cycle, which pulses may be used to break down the associated connections.

Abstract: 903,289. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 18, 1960 [Nov. 26, 1959], No. 40170/59. Class 39 (4). Control apparatus for moving an elongated neutronabsorbing member vertically into and out of a reactor core comprises a nut member restrained against rotary movement. electromagnetic means for releasably suspending the neutron-absorbing member from the nut member, and a screw member restrained against axial movement rotatably engaged with the nut member so that rotation of the screw member results in axial movement of the nut member and hence the neutron-absorbing member. In Fig. 1 a nut member 3 rides on the threaded portion of a central rotatable spindle 2, the threads of the spindle being engaged by a plurality of balls housed in grooves formed in part of the nut member 3. An extension 10 is bolted to member 3 and carries the coils and core of an electromagnet 5 which normally retains a soft iron plate 14 bolted to a sleeve 12 to which the neutron absorbing member 4 is attached. When the magnet 5 is deenergized the neutron absorbing member drops into the reactor core and its fall is checked by a tubular piston 16, attached to sleeve 12, entering a dash-pot chamber 21 attached to the lower end of spindle 2. The member 4 can be recovered by winding down the nut 3 until the magnet 5 is again in contact with the plate 14. A key 26 fitted in a keyway cut in the channel 1 of the reactor core engages in slots in members 10 and 12 to prevent their rotation but allow axial movement. In a modified arrangement the magnet 5 is adapted, as in Specification 903,288, to incorporate in its flux path discrete portions of material having a Curie point related to the maximum safe operating temperature, so that if this temperature is exceeded the reluctance of the magnet is increased sufficiently to allow release of the neutron-absorbing element.

Title: Determination of the location of a vehicle
IPC: B66B1/34
Filed: 1977-09-27
Abstract: An elevator control system using vertically elongated single-turn loops of wire movable with the car past a vertical column of stationary coils of wire, one at each floor, which are de-energized one at a time repetitively at high speed. The sudden collapse of magnetic flux from a coil induces a pulse into the loops if the car is adjacent. Each loop has one or more twists so that the polarities of the induced pulses vary in a predictable manner over the vertical length of the loops. When pulses are induced in the loops, the unique combination of positive and negative pulses defines the quantized distance between the car floor and the building floor whose coil caused the pulses. The quantized distance between the car floor and any desired target floor in the building is computed repetitively by adding the pertinent floor heights, as stored in a memory, to the reading obtained from the loops.

[Also in Division F1]  A valve 20 has an inlet 95 communicating with a manifold (18), Fig. 1 (not shown), feeding combustion gases from a solid fuel combustion chamber (16) to a set of nozzles (19) driving a turbine (10). The valve plunger 83 is screwed at 84 into a movable member 86 having a flange 87 forming a seat for a coil spring 80. Member 86 abuts a fixed flange 82 on the valve body such that the conical head 98 of plunger 83 is initially slightly spaced from its seat 96. The initial compression of spring 80 is set by a screw 75 acting on the upper spring abutment 78. Head 98 is disposed in a chamber 99 and has a flange 97 upon which the gas flow through inlet 95 impinges such that the valve is sensitive to both pressure and flow rate through the inlet, thus maintaining a substantially constant burning rate of the solid fuel with varying ambient conditions. The gases leave the valve through .an outlet 93 leading to a nozzle (19a) directed on to the turbine (10) In a modification, Fig. 3 (not shown), the head 98 of the valve plunger ;83 has a dished flange (97<SP>1</SP>), the degree of flow sensitivity being proportional to the depth of the dished surface (100).

One of the keys 30 is first inserted and the other ground to a substantially accurate fit so that on assembly the keys fit the grooves 32 and the outer face of the keyway 31 to prevent backlash. A sealing member 23 is mounted in a groove extending around the vane periphery to seal the vane with respect to the inner cylindrical surface of the casing, the end closures and the portion 14. The keys it is stated substantially take all the shear loads with the bolts being subjected only to tension.
