Title: Generator for producing acetylene under pressure of the type "carbide into water"
IPC: C10H15/12
Filed: 1931-12-16
Abstract: <PICT:0383765/IV/1> <PICT:0383765/IV/2> <PICT:0383765/IV/3> Plant for generating acetylene under pressure comprises lower and upper receptacles B, B<1> communicating by a tube D, together with generating chambers A mounted on the lower receptacle B and supporting carbide holders X from which carbide is automatically fed to the chambers A with decrease in the gas pressure in the receptacle B.  Normally, the generated gas passes through a tube C<1> into the receptacle B, from which it is withdrawn for use.  Decrease in the gas pressure in the receptacle B causes inflow of water from the receptacle B<1> through the tube D, and depresses a float Sch in the receptacle B<1>.  The float is connected by rods P, Q, R<1>, S<1> to pawl and ratchet mechanisms U<1>, Fig. 2, on a shaft U which actuates through gearing W the shafts Y passing through the carbide containers L. The containers L are divided into compartments by radial partitions M, Fig. 4, each compartment being closed at the bottom by a plate N, Fig. 2, hinged at the outside of the container.  The plates N are normally secured by latches O hinged at O<1>. Each shaft Y carries, just above the container L, a collar T, Fig. 4, broken for about the width of one compartment, a finger J<1>, also mounted on the shaft Y, projecting into the gap. When the shaft Y rotates, the finger J<1> pushes outwards the upper end of one of the latches O and releases the bottom plate N of one compartment, whereupon a charge of carbide falls into the chamber A.  Gas produced in excess of requirements escapes through the apertue l in the tube D into the receptacle B<1>, which communicates with the atmosphere through the tube D<1>.  Each generating chamber is provided with a siphon tube f carrying a one-way valve V and opening into the lower receptacle B. Each tube f acts as a safety device when the corresponding valve C is closed.  For example, when a container L is to be charged, the valve C is closed and water is introduced into the chamber A up to the level h<2>; after recovering the charged container, the valve C is opened and water is withdrawn through the sludge valve G until it falls to the normal working level H.

Filed: 1966-08-04
Abstract: Novel compounds of the formula <FORM:1093807/C2/1> wherein R1 and R2 are H or C1- 5 alkyl and R3 and R4 are C1- 5 alkyl are prepared by reacting 2,2-dialkyl-1,3-propylene diamines with urea, phosgene or carbonic acid esters to form 5,5-dialkylhexahydropyrimidones - 2, adding on formaldehyde in the presence of alkaline reagents, and, if desired, etherifying the resultant N,N1-dihydroxymethyl derivatives with alcohols in the presence of an acid catalyst.ALSO:A finishing agent for textile materials consisting of or containing natural or regenerated cellulose comprises a solution of a compound of the formula:  <FORM:1093807/D1-D2/1> where R1 and R2 are H or C1-5 alkyl and R3 and R4 are C1-5 alkyl.  The finishing agent is preferably used in aqueous solution together with an acid catalyst, and may be reacted with the textile material to form acetal bonds when wet or wholly or partly dried, either immediately or after storage in the impregnated but unreacted condition.  The finishing agents may be used together with known finishing agents, e.g. dispersions of polymers such as a copolymer of n-butylacrylate, polyethylene, an ethylene oxide adduct, bleach, oxalic acid, NH4Cl and/or MgCl2.  The finishing treatment preferably takes place at 130 to 160 DEG C, and the acidic catalyst may be a compound which decomposes to become acidic at these temperatures.

Abstract: 1279806 Edge type filter C W BARRETT 11 July 1969 [11 July 1968] 35046/69 Headings B1D and B1T [Also in Division B3] A filter 22, which is inserted in an air outlet of a mould 20 to allow egress of air when a mixture of sand and oil or resin is blown into the mould, or when gas is subsequently blown in to set the mixture, when making a core for metal casting, comprises a tubular support 26 bridged at one end by a disc 32 of metal, which has elongated openings 40 (Fig. 2) which define a series of intercalated fingers. Disc 32 is up to 0.020 inches thick, and openings 40 are prepared by acid etching from one or both sides (Figs. 5, 6, not shown). The fingers 44 may be vibrated by the gas stream, or the disc may be a two-ply laminate of different stainless steels so that the fingers are flexed by temperature changes, such vibration of flexure releasing sand particles trapped in the openings 40. The openings may be wider at the downstream face of the disc than at the upstream face. Figs. 3, 7,9 (not shown) illustrate alternative configurations of openings, and Fig. 8 (not shown) illustrates a shoulder (60) in the support which limits finger deflection.

Title: Improvements in or relating to anti-skid devices for road vehicles
IPC: B60B39/00
Filed: 1933-12-13
Abstract: 428,551. Vehicle anti - skid devices. PARRY, T. J., Petton Hall, Burlton, Shrewsbury. Dec. 13, 1933, No. 35050. [Class 108 (ii)] An anti-skid device comprises a pair of independently rotatable wheels mounted on a shaft adapted to be tilted by a road-surface contacting element normally held out of engagement with the road surface but adapted to be brought into engagement with the road by manual operation. As shown two horizontal members 2 are clipped to the axle and to the tongue shaft of the vehicle, a third transverse member 3 is secured to the ends of the members 2 and a pair of triangular plates 4 depend from the member 3. Upon a pin 5 on the lower end of the plates 4 a tiltable shaft 7 is pivotally shackled and upon this shaft 7 are mounted spur wheels 8 and a road-contacting element 9 the latter having also a spring 10 tending to elevate the element. The element 9, when desired, is brought into operation by means of a cord 11 acting along the axis of the pin 5 and preferably from the brake lever. Side movement of the vehicle then causes the shaft 7 to tilt bringing one of the wheels 8 into contact with the road tending to press its teeth into the road and prevent side skid. The other wheel 8 contacts with the plates 4 and so limits the downward movement of the road-contacting wheel. The device may be adjusted.

Vapour-apparatus, arrangements of.-In an arrangement for supplying mercury arc rectifiers with 12-phase current obtained from a transformer having a 3-phase primary 1 and twelve secondary phases obtained by phase combination from star-connected groups 2 - - 5 of secondaries, there are provided two sets of interphase transformers 6, 8 producing high impedance in the anode circuits to different sets of harmonics. The interphase transformers 6 connected between the star points of the secondaries and the negative side of the D.C. system produce high impedance to all harmonics in the anode currents that are multiples of three except those that are multiples of twelve, whilst the interphase transformers 8 connected in the anode leads from the secondary phases produce high impedance to harmonics that are multiples of four except those that are multiples of twelve. The twelve phases are lettered consecutively A to L in order of phase sequence, each leg of the core of interphase transformers 8 having four windings carrying phase currents 90‹ apart. In a modification in which two 6-phase star-connected secondary groups are employed instead of four 3-phase groups, the interphase transformer set connected between the star points and the negative side of the D.C. circuit provides impedance to all harmonics that are odd multiples of six, the inherphase transformer set in the anode leads providing impedance to harmonics that are multiples of four.
