Abstract: Detergent compositions which may be in the form of shampoos or dishwashing formulations contain as an essential ingredient amine oxides of the formula <FORM:1066763/C4-C5/1> wherein A represents C8-18 alkyl or alkenyl, R represents A, C1-4 alkyl or the group -CqH2qOH, and q is 2 or 3, with or without an anionic or non-ionic surface acting agent, e.g. alkyl-aryl sulphonates, alkyl sulphates or alkyl or alkylphenyl polyether sulphates. Other ingredients which may be present are alkylolamides, sodium tripolyphosphate, tetrapotassium pyrophosphate, soda ash, sodium metasilicate, aminopolycarboxylate-type sequestering agents, ethanol, isopropanol and/or water. The alkyl sulphates may be in the form of alkali metal or alkylolamine salts, and the sulphonates may be in the form of sodium, ammonium or alkanolamine salts.ALSO:The invention comprises novel amine oxides of the formula <FORM:1066763/C2/1> wherein A represents C8- 18 alkyl or alkenyl, R represents A, C1- 4 alkyl or the group -CqH2q-OH, and q is 3, and the preparation of these and other amine oxides of the above formula wherein q is 2 by (1) reacting a monosulphate ester of the formula AOSO3M (wherein M is a cation) with an alkylolamine of the formula R1NHCqH2qOH (wherein R1 represents hydrogen, a C1- 4 alkyl group or the group -CqH2qOH) in the presence of a solvolytic medium and a base at a temperature of at least 100 DEG  C., and (2) reacting the resulting intermediate tertiary amine with a peroxidizing agent.

Title: Improvements in or relating to the testing of fluid properties such as density or physical composition
IPC: G01N21/25
Filed: 1960-06-02
Abstract: 957,422. Testing fluid properties. MINNEAPOLIS-HONEYWELL REGULATOR CO. June 2, 1960 [June 2, 1959], No. 15969/60. Heading G1A. Apparatus for testing the density, specific gravity or composition of a fluid as a function of the refractive index comprises a source 12 of radiant energy such as light energy, which emits a broad band of wavelengths, a radiant energy sensor 54 responsive to the said wavelengths, a radiation guide 20 such as a sapphire rod, which receives the said radiant energy and leads it to the sensor 54, the radiant energy being substantially retained within the guide by multiple internal reflection, and a container 21 to hold the fluid under test in contact with at least a portion of the surface of the guide 20, whereby a change in refractive index of the fluid is detected as a radiant energy loss from the guide/fluid interface by the sensor 54, characterised in that before reaching the portion of the guide 20 in contact with the fluid the radiant energy pases through a filter 19 comprising a body of the same fluid as that under test. The purpose of the filter 19 is to prevent wavelengths of radiation which are strongly absorbed by the fluid under test from reaching the guide 20 since such absorption would cause errors in the refractive index measurement. As shown the fluid flows continuously through conduits 32 and 34 to the transparent filter 19 and through the container 21 and flows out through conduits 40 and 48. The apparatus may alternatively be used for batch measurements. The sensor 54 comprises a lens and a light sensitive element 56 which is connected to a meter 62 calibrated to indicate density, specific gravity or composition of the fluid. In a modification (Fig. 2, not shown) the container 21 is provided with a two way junction and two position valves &c. in order that a mixture of two fluids may be fed to the chamber and the filter 19.

Title: Improvements in or relating to a process of producing test fluid for the procedure of testing for syphilis
IPC: A61K49/00
Filed: 1936-07-17
Abstract: A fluid for use in testing for syphilis is obtained by prolonged warming of a mixture of ground heart or other muscle with alcohol, cooling and filtering the liquid obtained, and adding cholesterin and one or more soluble organic dyestuffs of blue, violet or green colour.  Dyes specified are crystal violet, azur II, and methylene blue.

Title: A new or improved device for the electric winding-up of the barrel spring of a clockwork mechanism
IPC: G04C1/06
Filed: 1946-07-05
Abstract: 614,098. Reciprocating Motors. SCHILD & CO. SOC. ANON. July 5, 1946, No. 20148. Convention date, Jan. 11. [Class 35] [Also in Group XVIII] A device for the electric winding-up of the barrel spring of a clockwork mechanism comprises an electromagnet 1, adapted to be fed from a source 28 of electrical energy, and an armature 4 which can oscillate between the polepieces 2, 3 of the electromagnet 1, characterised in that the armature 4 carries a pawl 9 which is adapted to rotate a ratchet-wheel 10 for rotating the axle 11 of the barrel 12 of the clockwork mechanism to wind up the spring 13 and in that the ratchet-wheel 10 is also in engagement with a stop pawl 15 carried by a pivotable arm 14 which supports a rod 20 provided with a contact 21 which is adapted to control the passage of the electric current to bring about oscillation of the armature 4 until the spring 13 is sufficiently tensioned, whereupon the armature is no longer oscillated until the tension of the spring 13 again falls below a desired minimum value. The device operates as follows: when the tension of the spring 13 falls to a minimum the arm 14 is pulled by a spring 19 against a stop 18, whereupon the contact 21 touches a conductor plate 23 carried by an insulated fork 22 loosely mounted on the axle 5 of the armature 4. The circuit to the electromagnet 1 is thus completed and the electromagnet is energized, the armature 4 is rocked counterclockwise, breaking the electric circuit and the pawl 9 steps on the ratchet wheel 10. A spring 7 then resets the armature 4 and the operation continues as before. When the spring 13 is sufficiently tensioned the force exerted on the pawl 15 by the ratchet wheel 10 causes the arm 14 to pivot until it abuts a stop 17 in which position the member 21 is disengaged from the plate 23.

Title: Improvements in or relating to mountings for electron discharge devices
Inventor: RIDGEWAY DENIS VICTOR
IPC: H04N5/74
Filed: 1951-08-29
Abstract: 736,854. Cathode - ray tube mountings. CINEMA-TELEVISION, Ltd. Aug. 28, 1952 [Aug. 29, 1951], No. 20406/51. Class 40 (3). A mounting for supporting a discharge tube relatively to an optical system has separate means for adjusting the tube in three directions linearly at right angles and by rotation about two axis at right-angles to each other and to the axis of the optical system. In Fig. 2 the heavy barrel 5 of the optical system carries two pivot screws 6, 6<SP>1</SP>, and spring steel arms 7, 71, the upper ends of which are attached to brackets 8, 8<SP>1</SP> on opposite sides of the gimbal ring 9 to give the latter translational and rotational movement relative to the barrel. The translational screw A has its end held in the jaws of bracket 10 which form a curved slot to allow the rotational adjustment. Brackets 15, 15<SP>1</SP> are pivoted at 14, 14<SP>1</SP> to ring 9 and have slots with curvature centred at O on the axis 6, 6<SP>1</SP>, pins 16 on the arms 17 secured to the second gimbal ring 18 moving in these slots under the action of screw D. A cylindrical member 19 holding the screw D can turn in the bracket 15<SP>1</SP>. The tripod 21 supported by ring 18 terminates in a ring and spider assembly 22, 23 and a clamp 24 which engages a long insulating tube 25 supporting the discharge device. A screw held in the ring 22 coacts with a nut on the clamping ring 24 to give longitudinal adjustment of the tube 25. Clamping rings and screws 32, 33, 35, support the discharge device 26 in the tube 25. A screw B (Fig. 3, not shown) which is rotationally and slidably held on gimbal ring 18 works in a nut which is rotatable and slidable in a bracket attached to the ring 9 and gives adjustment in a direction at right-angles to that obtained by the leaf-springs 7, 7<SP>1</SP>. The use of control B demands a correction of the rotational adjustment about pivots 6, 6<SP>1</SP> and to avoid this interaction the construction is modified by replacing pivot pins 14, 14<SP>1</SP> by pins moving in straight slotted guides. Interaction is also avoided with some loss of rigidity by the modification of Fig. 5 in which the gimbal rings are co-planar and are linked by pairs of leaf-springs 40-40<SP>1</SP>, 41-41<SP>1</SP>. The adjusting screw B works in a nut held captive in an arcuate slot in bracket 47 and gives translatory movement between the two rings. Screw E, which is captive in a member 50 pivoted in a bracket 51 integral with ring 9, gives translatory movement between the latter and the barrel 5.
