Abstract: 717,225. Cooling systems for internalcombustion engines; heating vehicles. BAIER, O., BAIER, W., BAIER, S., BAIER, L., BAIER, W., and SCHLUMPRECHT, E., [trading as BAIER KOMMANDIT-GES., WEBASTO-WERK, W.]. Nov. 21, 1952 [Nov. 21, 1951], No. 29465/52. Classes 64(2) and 64(3) Fig. 1 shows a heating and cooling system for motor vehicles in which the internalcombustion engine 1 is connected to a radiator 4 by flow and return pipes 2, 3. A thermostatically controlled valve 5 in the pipe 2 allows the coolant to flow to the radiator when the temperature of the coolant rises above a predetermined value. A circulation pump 6 is inserted in the return pipe 3. Coolant is led off the pipe 2 . by a pipe 7 to a pump 18 which circulates the coolant through a heating appliance 8 whence it passes through a discharge pipe 9 and supply pipes 10, 11 to the return pipe 3 and is then pumped into the coolant chambers of the engine 1. Thus the appliance 8 supplies heat to the engine for starting purposes. The discharge pipe 9 is connected to the supply pipe 10 through a three-way cock 12 which is connected to a by-pass pipe 13. Thus the coolant can be led through heater elements 15, 16 to heat the interior of the vehicle or to demist the windscreen or similar purposes. The coolant is led from the elements 15, 16 to the supply pipe 11 which passes through the battery'17 of an electric starter for the engine so that the battery may be heated to facilitate starting in cold weather. The pump 18 for the heater 8 and a fuel supply pump. 21, a blower 22 for combustion air and an atomizer 23 are driven by an electric motor 24, Fig. 2. The fuel, which may be, that used for the vehicle, is delivered by the pump 21 through a pipe 25 to the atomizer 23 whence mixed with air it passes into the combustion chamber 26 to be electrically ignited. The combustion gases pass through the cylindrical jacket 27 of the chamber and are deflected at the end wall 28 to pass between radial fins 29. The fins, heated by the passage of the  gases, conduct heat to the annular chamber 20 through which the coolant circulates before being led off by the pipe 9.

Patent GB-1006107-A (GB)
Title: Method for cooling ticl combustion products
IPC: C09C3/04
Filed: 1962-08-01
Abstract: Titanium dioxide produced by burning titanium chlorides in oxygen is cooled rapidly to below its tack point (approximately 600 DEG  C.). The hot gases containing the titanium dioxide particles are passed up a cooling tower down which inert particles of a coolant material having a particle size of 10-100 mesh Tyler are passed.  The hot coolant material is separated and cooled at the bottom of the tower, whilst cooled titanium dioxide is withdrawn at the top of said tower. The preferred coolant materials are silica, titanium dioxide and alumina and the ratio of flow is such that approximately 8 1/2 times as much coolant material passes down the tower as titanium dioxide goes up.  Coarse grains of coolant material 4-10 mesh may be introduced into the tower to remove adhering titanium dioxide from the apparatus, also coolant material 10-100 mesh may be introduced at an intermediate point in the tower. The coolant materials are subjected to water cooling, gas elutriation and seiveing, and are then recycled to the top of the tower or an intermediate point.  The temperature of the titanium dioxide suspension on entrance is about 1400 DEG  C., and may be produced by a metal chloride-oxygen burner situated at the foot of the tower and having a water-cooled guard tube above the burner orifice.

Title: Improvements in tap-changing arrangements for electrical transformers
Inventor: BROWN JAMES KINGHORN
IPC: B60L9/26
Filed: 1957-09-19
Abstract: 890,495. Transformers; rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 12, 1958 [Sept. 19, 1957], No. 29529/57. Class 38 (2). [Also in Group XXXVII] In a tap-changing system for the two-part secondary winding of a transformer T supplying traction motors through a mercury arc or other rectifier bridge RA1, RA2, RB1, RB2 the two groups of tap-changing switches 1A-7A and 1B-7B are connected to an earthed or lightlyinsulated common output connection (which may be joined to the mid-points of preventive coils P2, P3) and, under any tapping conditions, operate at the same potential or at a comparatively small potential with respect to one another. In balanced conditions the midpoints of coils P2, P3 are at earth potential so that only half the voltage across the appropriate coil can appear at the movable contacts of the tap-changing switches. The preventive coils P2, P3 may be omitted, the appropriate rectifiers being rendered non-conducting during tap-changing to avoid short-circuiting the intertap windings as described in Specification 890,492. The primary winding P may be tapped. The tap-changing switches may be cam-operated contactors, as described in Specification 815,078, or may be groups of electromagnetic or electro-pneumatic switches or contactors. Tap-changing in the two groups may take place alternately or simultaneously.

Title: Improvements in hydraulic steering gear suitable for vehicles, ships and the like
IPC: B62D5/24
Filed: 1931-10-26
Abstract: 391,775. Steering vehicles and ships. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.-(Vickers, Inc. ; 7752, Dubois Street, Detroit, Michigan, U.S.A.) Oct. 26, 1931, No. 29614. [Class 79 (v).] Comprises hydraulic servomotor steering- gear in which a valve coaxial with and directly operated by the steering-shaft or column controls an hydraulic motor mounted directly on a cross-shaft operating the members to be steered. The gear has a " follow-up " action, and is operable by hand if fluid-pressure fails. The steering-shaft 4 has fixed thereon a coaxial valve 8 and has a lost-motion connection 31 with a worm 5 gearing with a sector on the rocker or cross-shaft 3 operating the steering wheels. The valve 8 controls the fluid connections between a continuously-driven pump A and a vane motor 27 on the cross-shaft 3, so that when the valve is rotated by the shaft 4 the motor is rotated by fluid pressure in the corresponding direction and operates the steering wheels. At the same time the motor rotates the worm 5 and a valve member 10 fixed thereto so that when the movement of the shaft 4 stops the motor stops as soon as the member 10 has caught up to the shaft 4 and valve 8. The valve comprises a member 8 with longitudinal grooves 11 and a sleeve 13 fixed to 8 and provided with ports 14 each of which always registers with a circumferential groove a, b, c, or d formed in the casing 1 of the gear. The grooves a, b communicate with outlet and inlet ports 17, 16 from the pump A, and the grooves c, d communicate with ports 18, 19 leading to the motor. The valve 8 encloses the member 10 fixed to the worm 5, the lost-motion connection 31 allowing a slight amount of relative rotation between these parts. The member 10 has ridges 12 slightly narrower than the grooves 11, so that when the gear is stationary and the parts 8, 10 are in the neutral position shown in Figs. 6 and 7 oil can circulate from the pump through the valve and back to the pump, pressure being maintained in the motor chambers at the same time. When the valve 8 is moved from the neutral position as shown in Fig. 8, the lag of the member 10 causes the ridges 12 to close the communication between grooves a, b, whilst leaving a connected to c or d, and b to d or c. The motor is thus energized and rotates the shaft 3, while the valve member 10 follows up the valve 8. When the steering- shaft 4 is stopped the valve member 10 is returned to its neutral position relative to the valve 8 by the action of centring springs forming part of the lost-motion connection 31. Byepass and relief valves 40, 41 are provided in case liquid circulation is stopped or if hand operation of the gear is necessary. The motor chambers are formed in a member 22 and a cover 2 of the gear casing 1, and annular passages 29, 30 for the liquid are provided in the members 22, 2. The gear is bolted to the frame by means of the flanges 20 on the cover.

Tertiary-amino-alkylated primary amines are obtained by a process which comprises (a) catalytically hydrogenating 2-methylene-glutaronitrile to produce 2-methylglutaronitrile, (b) reductively alkylating 2-methyl-glutaronitrile in the presence of an amine, HNR 1 R 2 , to produce 2-methyl-5-NR 1 R 2 -valeronitrile, (c) hydrolysing 2 - methyl - 5 - NR 1 R 2  - valeronitrile, preferably in an aqueous mineral acid, to produce 2-methyl-5-NR 1 R 2 -valeramide and treating the latter with an aqueous alkaline solution of an alkali metal hypohalite to produce 2-amino-5-NR 1 R 2 -pentane, where NR 1 R 2  is a tertiary amino group and R 1  and R 2  are the same or different and represent lower or higher alkyl, hydroxy lower or higher alkyl, lower alkoxy higher or lower alkyl, di-lower alkylamino lower or higher alkyl, C 3-7  cycloalkyl, phenyl or substituted phenyl, said substituents being hydroxy, lower alkoxy, dilower alkylamino, trifluoromethyl, lower alkylmercapto or halo, or R 1  and R 2  taken together form a heterocyclic ring containing at least one heteroatom, the terms " lower " and " higher " denoting C 1-8  and C 8-18  respectively. The first step of the process to produce 2-methyl glutaronitrile is suitably effected at 60-80‹ C. under a pressure of 100-200 p.s.i. hydrogen in the presence of a catalyst such as palladium, platinum, Raney cobalt or Raney nickel which may be supported on a carrier such as carbon, barium sulphate, strontium carbonate, calcium carbonate or alumina. The reductive alkylation in the second stage is preferably effected at 90-110‹ C. under a hydrogen pressure of 100- 500 p.s.i. employing the same catalyst as in the first stage. The hydrolysis in the third of the process is preferably conducted at 60-65‹ C. in 85-95% sulphuric or phosphoric acid. The Hofmann type reaction in the final step of the process is conducted in a conventional way suitably starting the reaction at about 0‹ C. and completing the reaction by heating to about 75-100‹ C. The intermediates formed in the above steps may be isolated together with smaller amounts of the corresponding 4-methyl- 5-t-amino substituted isomers which are also formed.
