Title: New glycol or polyglycol esters and a process for the manufacture thereof
Inventor: FRANK KARL
IPC: D06M13/385
Filed: 1952-03-21
Abstract: The invention comprises as new products glycol or polyglycol mono-esters of a condensation product of a fatty acid having at least 12 but not more than 27 carbon atoms and an amino carboxylic acid, which esters are suitable for use as textile softening agents, and in which the ester residue contains from 1 to 4 ethenoxy (-CH2.CH2.O-) groups.  They may be obtained by reacting the condensation product of the fatty acid and amino acid at a raised temperature and in the presence of a condensation catalyst with from 1 to 4 molecular proportions of ethylene oxide, or by reacting with 1 molecular proportion of the appropriate polyglycol or ethylene glycol, or by reacting a salt of the condensation product at a raised temperature with one molecular proportion of ethylene chlorhydrin.  Specified amino carboxylic acids are glycocoll, sarcosine, and protein hydrolysates and the fatty acids used may be natural or synthetic fatty acids.  The reaction with ethylene oxide is preferably carried out at under pressure and at elevated temperature.  In examples (1) industrial coconut oil fatty acids are condensed in the form of the acid chlorides and in the presence of sodium hydroxide solution with glycocoll and the coconut oil fatty acid glycocollide obtained is freed from water and reacted with ethylene oxide in the presence of sodium methylate at 120-170 DEG  C. and under pressure so as to cause 4 molecular proportions of ethylene oxide to combine additively with the glycocollide to yield a compound useful as a preparation agent for staple fibres of regenerated cellulose; (2) industrial oleic acid is condensed with an equimolecular quantity of sarcoside and the anhydrous sarcoside converted to its anhydrous sodium salt which is then reacted with 1 molecular proportion of ethylene chlorhydrin at raised temperature to yield a preparation agent for regenerated cellulose; (3) stearic acid sarcoside is reacted with ethylene oxide in the presence of caustic soda to introduce 1 and 4 molecular proportions of ethylene oxide respectively; (4) a condensation product of oleic acid and a protein hydrolysate obtained by hydrolysis of leather with a caustic alkali is condensed in the form of concentrated aqueous paste of its sodium salt with 1 molecular proportion of ethylene chlorhydrin at a temperature of at least 100 DEG  C. with or without pressure to yield a product similar to that formed in (2).  Specifications 401,712 and 599,280 are referred to.

Title: Improvements in and relating to apparatus for producing the axial grinding spindle movement in internal grinding appliances
IPC: F01L25/06
Filed: 1957-03-06
Abstract: 856,432. Traversing mechanisms for internal grinders. ALLEMANN A.G., H. March 6, 1957 [March 6, 1956], No. 7471/57. Class 60. [Also in Group XXXII] Apparatus for producing axial movement of the spindle of a grinding machine comprises a working piston 26 which is actuated by compressed air through associated control memmembers and is mechanically connected to the grinding spindle 4. The spindle 4 is rotated in bearings 3 which are axially movable in a housing pivotally connected to a plate adapted to be mounted on the cross-slide of a lathe. The spindle is rotated by a compressed air turbine 5 provided with a lug 6, which cooperates with stops 8, 9 during the axial movements of the bearing and spindle, and the bearing is connected by a bolt 27, Fig. 3, to a piston 26, the ends of which are alternately supplied with air pressure. Compressed air is supplied through a connection 12, Fig. 2, to chambers 13, 16, 19, and channels 17, 20 in valves 7, 14 disposed in the respective chambers 16, 19. In the position shown in Fig. 2, the spindle is in its rearward position and the lug 6 has moved the valve 7 to the left by means of the stop 8 to connect the channel 17 to a bore 18, whereby the air pressure urges the valve 14 to the right, and connects the channel 20 to a bore 21 to urge the piston 26 and the grinding spindle also to the right, or forward position. When the lug 6 contacts the stop 9, the reverse process takes place and the spindle moves to the left. Air from the inoperative ends of the valve 14 and piston 26 passes through bores 29, 30 to a silencer 25 where it is led to the spindle bearing to escape to atmosphere and prevent the entry of dust to the mechanism. In order to produce a braking effect on, the spindle movement a piston 32, Fig. 3, is connected to the piston 26 and during its movements causes oil from a reservoir 36 to flow to and from spaces 33, 37 through ball-valves 25, 38. The balls of the valves are spring-urged against the eccentric portion of a rod, which can be rotated by a handle so that the flow of oil through the valves can be adjusted together to control the speed of reciprocation. One end of the rod is located in an adjustable eccentric bearing so that the speed of movement in one direction may be different to that in the other. Recesses 40, 41 are formed in the bearings 48 to provide air cushions which permit the initial speed of movement after reversal to be accelerated for a short distance. The clearance between the piston 32 and bearings 48 is sufficiently large to allow oil to emerge and collect in a reservoir 13<SP>1</SP> where it is supplied to lubricating points by the air pressure.

Abstract: 583,873. Impedance networks. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. April 21, 1944, No. 7481. [Class 40 (iii)] [Also in Groups XXXV and XXXVI] The attenuation or phase constant of a fourterminal network is varied, while its characteristic impedance remains constant or varies according to a desired law, by axially shifting an inner set of conductors' with respect to an earthed outer sheath, the inductances and capacitances of the network being thereby simultaneously modified. A low-pass . filter or delay network comprises series inductance residing in coils 3 and shunt capacity between inner and outer cylindrical conductors 4<1>, 2, the outer conductors 2 projecting inwards from the earthed outer screen 1. The coils 3 and condenser plates 4<1> may be carried by an ebonite rod 5 with screwthreaded end members 8, 8<1>, so that rotation of the outer screen 1 causes relative axial movement. The coils 3 ma,y be varied in pitch and diameter so that the inductance, as affected by coupling with the annular closed conductors 2, varies with axial movement according to any desired law, and the condenser plates 3 may be shaped for a similar purpose. Preferably, the ratio L /C and consequently the nominal impedance is held constant while the product LC and consequently the cut-off frequency is varied. The termination may be mid-series or mid-shunt, Figs. 3, 4 (not shown). For very high frequencies, the coils may be replaced by straight strips of foil which may be shaped.

Abstract: 723,028. Measuring qualities of tobacco by radiation beams. BRINKMAN GES. March 25, 1952 [April 21, 1951], No. 7689/52. Class 40 (3). Measured quantities of tobacco are produced by means of a radiation source and a radiationresponsive device measuring the density of a column of tobacco of uniform cross-section. As shown, tobacco is fed by travelling bands 2, 3 through a measuring passage 4 having windows 6 transparent to the rays in use, on to a flap 11 on which each measured quantity is received. It is stated that the clear space above the band of tobacco should not be less than the normal height of the pocket in order to make the absorption of the rays by the tobacco large compared to that of the windows. The rays from the source 5, which may be an X-ray source or radio-active isotopes are received by two differentially connected counter tubes 7, 7a. Tube 7a is for comparison purposes only and receives radiation through a comparison sheet of synthetic resin material. When the desired quantity of tobacco has passed the measuring position amplifier 13 operates through a relay 8 and electromagnets 9, a cutter 10 and a flap tilting mechanism 11 which separate and deliver the gauged quantity of tobacco. The lowering of the cutting blade 10 and flap 11 operates switches 16, 16<SP>1</SP> which short circuit the output of amplifier 13 and deenergize the cutter operating and flap-operating magnets.

Title: Control of variable-stroke power hammers
IPC: E02D7/10
Filed: 1965-02-24
Abstract: 1,039,229. Power hammers. RAYMOND INTERNATIONAL Inc. Feb. 24, 1965 [April 15, 1964], No. 8038/65. Heading B3H. [Also in Division E1] An hydraulic power hammer, suitable for use in pile driving, includes a ram 21 attached to a piston 41 in a cylinder 12, and controlled by means of a cycling valve 34. After each downward working stroke of the ram the valve is reset for raising the ram by means of a water hammer effect. A vertically slidable cam 28 moves with the ram, a cam follower 29 being linked to the spool 33 of the valve. As shown, the piston and ram are moving downwardly since the fluid supplied from a source 42 to the upper part of the cylinder, through lines 44, 45, 46 and 47, acts on a greater area than that supplied at 56 to the lower part of the cylinder. When the ram strikes a pile, the sudden deceleration of the piston causes a sudden rise in pressure in the line 47, due to water hammer, this rise causing a release valve 50 to move the valve spool 33 to the right. This vents the upper end of the cylinder through lines 54, 55, and 43, thereby causing the piston to rise. Simultaneously the cam follower is rotated by the link 32 to the dotted position so that, as the piston nears the top of the cylinder, the cam 28 shifts the follower out again to reset the cycling valve to its first position. Should the ram not strike a pile, the piston passes inlet 56 and is cushioned on the volume of fluid beneath the piston, a check valve 57 preventing an excessive pressure rise in this volume. The cycling valve 34 is still actuated, however, the general rise in pressure of the system as provided by a positive displacement pump causing the valve 50 to operate. A modified but basically similar arrangement can be used where the valve 34 acts as a pilot valve, and a further, cycling, valve is provided. Figs. 7 and 8 (not shown) indicate a possible disposition of the power hammer in a cylindrical shell 80, the cylinder 53 being integral with the main housing 82 of the apparatus. A ram 86 is shown compressing a bulb pile 88 prior to filling the shell 80 with concrete.
