Abstract: 734,877. Vehicle steering gear. THOMPSON PRODUCTS, Inc. March 3, 1953 [July 24, 1952], No. 5857/53. Class 79(5). In a vehicle steering linkage, the track rod is reciprocable along its longitudinal axis in bearing means which resiliently resist movement of the track rod in any direction transverse to its longitudinal axis. As shown in Fig. 2, the track rod 3 is mounted for reciprocating motion in bearing guides 12, 13 rigidly attached to the longitudinal side frame members 20 of the vehicle. Pivotally connected to the rod 3, at 10, 11 are links 4, 5, which in turn are pivotally connected, respectively, to the steering arms 1, 2 rigid with the spindles of the steerable wheels (not shown). A drag link 6 is pivoted to the rod 3 and to an arm 7 fixed to the output shaft of the steering gear box (not shown). The links 4, 5 are adjustable in length by clamps 9, 8 for adjusting the toe-in of the wheels. Such adjustment may alternatively be provided by an adjusting sleeve inserted in the rod 3. The guides 12, 13, are suspended from the frame members 20 by hangers 14, 15, the guide bearing 12 being provided with a hemispherical pocket 14a against which a hemispherical bearing ring 17, is urged by a spring 18. The rod 3 is polygonal in cross-section and passes through the guide 12 and ring 17 which has a corresponding polygonal-shaped aperture. The guide 12 has affixed thereto a metal member 19a and a collapsible rubber or plastic member 19 to prevent ingress of dirt to the guide bearing. Slight rotation of the rod 3 about its longitudinal axis to prevent binding action in the steering linkage is permitted against the frictional force between the ring 17 and pocket 14a caused by the spring 18.

Title: Modified block copolymers and production thereof
IPC: C08F297/04
Filed: 1965-02-10
Abstract: A modified form of block polymer is produced by copolymerizing a major amount of a conjugated alkadiene with a minor amount of a vinyl aromatic hydrocarbon and, after substantially complete consumption of the alkadiene, copolymerizing a major proportion of the vinyl aromatic hydrocarbon remaining unreacted with a minor proportion of a conjugated alkadiene, the copolymerization being effected in the presence of an organo-lithium catalyst. The block polymer formed has a structure composed of two different blocks or segments, the first of which has a chain of diene units with lesser numbers of interspersed vinyl units and the other block or segments of which is a preponderantly polyvinyl chain with a few interspersed diene units. Polymerization is preferably effected in an inert hydrocarbon diluent.  Many suitable monomers and catalysts are specified; those exemplified are: dienes-1,3-butadiene, isoprene, 2-methyl-1,3-butadiene, 1,3-pentadiene, 1,3-octadiene, 2,3-dimethyl-1,3-butadiene, 2-ethyl-1,3-pentadiene, 2,4-dimethyl-1,3-hexadiene, and 3-methyl-1,3-heptadiene; vinyl aromatic hydrocarbons-styrene, 3-dodecylstyrene, 1-vinyl naphthalene, 2-vinyl styrene, 4-tert.-octyl-2-vinyl naphthalene, 3,4,5-tributyl styrene, and 4-hexyl styrene; catalysts-n-butyl lithium, isopropyl lithium, eicosyl lithium, 2-naphthyl lithium, 1,2-dilithio-1,2-diphenyl ethane, n-amyl lithium, 4-butylphenyl lithium, cyclohexyl lithium, and 1,4-dilithio-2-butene. Polymerization is either terminated with a small amount of isopropanol containing an antioxidant and the polymer subsequently coagulated with more isopropanol, or it is terminated with mixed fatty acids, antioxidant added and the solvent vaporized off.  The polymers are vulcanized using the usual vulcanizing ingredients.

Abstract: 405,810. Clinometers. BENNETT, H., Box 216, Galvestone, Texas, U.S.A. Feb. 27, 1933, No. 5913. [Class 97 (ii).] Relates to clinometers, particularly for determining the trim of ships, in which a pivoted arm b carrying a spirit level h is adapted to be angularly adjusted by a screw c. To ensure that equal rotational movements of the screw effect equal angular movements of the arm, the latter rests on a bearing surface l which is moved by the screw and is curved with a radius equal to the distance between the axes of the screw and arm pivot m. In the form shown, the screw c is rotatably mounted in the carrier e and is adapted to move the sleeve d carrying the bearing surface l. The carrier e may be adjusted along a dove-tail groove p in the base plate in accordance with the size of the ship as indicated on a scale n on the arm b. The screw c is geared at i to pointers moving over a dial k and indicating the difference in level between the ends of the ship. Interchangeable bearing surfaces l may be provided.

IPC: H03K3/351
Filed: 1966-02-10
Abstract: 1,164,792. Temperature alarms. MUIRHEAD Ltd. 13 Jan., 1967 [10 Feb., 1966], No. 5943/66. Heading G4N. A temperature sensing circuit comprises the series arrangement of a temperature-sensitive resistor T and a temperature-insensitive resistor R5 across the output of a pulse generator, the junction between the resistors being connected to the emitter of a unijunction transistor Uj. The mark/space ratio of pulses (preferably from a multivibrator Trl, Tr2) is such that the pulses cause negligible heating of the thermistor T. At temperatures such that thermistor T has low resistance, capacitor C3 does not charge sufficiently to trigger the unijunction transistor Uj, but a sufficiently large change in temperature will cause sufficient increase in the resistance of thermistor T to trigger unijunction transistor Uj so as to trigger a monostable multivibrator comprising transistors Tr3, Tr4, the parameters of which being such that lamp L will flash. In Fig. 2 (not shown) transistors Tr3, Tr4 are replaced by a super-alpha pair of transistors so as to provide a similar performance.

Abstract: 1,000,172. Testing insulation. BRITISH INSULATED CALLENDER'S CABLES Ltd. Feb. 13,1964 [Feb. 14,1963], No. 6062/63. Heading G1U. In a method of testing the insulation of a mineral insulated thermocouple cable, the thermocouple cable is immersed in water in a closed container 1 which is sealed at 7, and gas under pressure (approx. 20 psi) is introduced into the space between the water and the seal via the inlet 4. A voltage of 500 v is applied between the thermocouple cable conductors and sheath after the thermocouple cable has been immersed for a specified time, and the leakage current which flows is measured. All thermocouple cables which show a resistance of less than 1, 000 Megohms between the conductor and sheath are rejected. By carrying out the test under pressure the effect of many days immersion in water at atmospheric pressure is simulated. A number of separate closed containers may be joined by means of the inlets and outlets 4 and 5 so that only one gas cylinder to provide pressure is required.

As the weft inserting needles reach the end of their inserting movement they strike a sloping surface 168 and cause upward movement of a block 68 causing upward movement of detent 42 against the action of a leaf spring 60 thus releasing extension 33 which under the action of a now compressed spring 37 causes rotation of needles 21 in the opposite sense to engage the inserted weft. Backward movement of slide 25 is not hindered by detent 42 since it has a sloping surface 142. Pivoted weft engaging members 51 are provided.

Title: Improvements in and relating to the production of acid tooth pastes
Filed: 1930-02-25
Abstract: In the manufacture of acid tooth pastes containing silica gel a mixture of the ingredients is subjected to a colloidal grinding at an increased temperature not greater than 70 DEG  C. for the purpose of causing the gel to assume the liquid state during the grinding whereby air is prevented from entering the mass.  The invasion of air is prevented to an increased degree by performing the colloidal grinding in an inert atmosphere soluble in the mass, e.g. carbon dioxide or by employing etheric oils, which have a high vapour pressure at the increased temperature of the grinding, as constituents of the paste.  The substances added must be soluble in the mass and must be such that the mass may be maintained in a liquid state during the colloidal grinding, whilst they do not prevent coagulation upon cooling: e.g. in the case of a silica-water-glycerine gel, tartaric, boric or benzoic acid may be added.  The mass may be subjected to a slow stirring during the coagulation.
