Title: Improvements relating to rims for vehicle wheels
IPC: B60B25/16
Filed: 1926-12-16
Abstract: 269,448. Perrault, R. Dec. 16, 1926. Detachable - rim attachments to wheels.-A detachable rim 7 is adjusted over the fixed arms 3 by means of a pair of locking-members having inclined seatings 25 co-operating with lugs on the rim 7. The members 6, having overlapping ends 8, are normally constrained by a spring 28 to occupy positions such that slots 5 in the outer wall of the fixed rim align with slots 24 in the members 6 leading to the seats 25. In this position, the detachable rim may be assembled, or removed. The relative circumferential movement of the members 6 is effected by a pinion 10 engaging rack teeth on the parts 8 and operated by a spindle 11. When the parts are in the locking position a pin 18 passing through the spindle 11 is forced, by a spring 22, into engagement with registering notches 17 in the overlapping parts 8 of the members 6. Tyre attachments to rims.-Fig. 12 shows a device (not claimed) for connecting the ends of a collapsable rim 7.

Title: Improvements relating to automatic weighing machines
IPC: G01G13/08
Filed: 1928-11-02
Abstract: 320,255. Hackett, H., and Whittaker, A. Nov. 2, 1928. Automatic-feed weighers.-An automatic weighing-machine comprises in combination a weigh pan carried on a counterbalanced beam, a hopper, an endless conveyer for carrying articles or substances from the hopper to the weigh pan, a pair of belts or the like in driving connection with the conveyer, a clutch whereby either of the driving belts or the like can be brought into action, and means dependent on the weighbeam for controling the clutch. The articles, such as nails, sweetmeats, or granulated material, are delivered from a shoot e to a conveyer belt d capable of being driven from a driving shaft s at either of two speeds by means of two belts and a clutch k. The conveyer belt delivers the material to a weigh pan a mounted on a weighbeam b. When the weighbeam tilts, a projection thereon releases a catch o and allows a hammer p to fall on to a catch q thereby releasing a spring-controlled slide r. The slide r actuates the clutch k so as to reduce the speed of the conveyer belt d and thus produce a dribble feed. When the charge is completed, a second projection on the beam operates through a similar, arrangement of mechanism to move the clutch to a neutral position and stop the conveyer belt. The stopping mechanism also automatically brings into operation mechanism for discharging the weighed material from the weigh pan and for re-setting the parts and initiating a further weighing operation. In a modification, the projection n is loosely carried on the beam and is moved by a counterweighted lever pivoted to the side of the machine and released by the initial movement of the beam. Instead of employing mechanical means, electromagnetic devices may be used for controlling the cycle of operations.

Patent GB-428871-A (GB)
Title: Improvements in or relating to the stabilisation of aqueous formaldehyde solutions
IPC: C07C47/058
Filed: 1933-11-21
Abstract: Formaldehyde is stabilized by adding an aliphatic nitrogen compound such as urea, thiourea, methylurea, dimethylolurea, diethyl thiourea, glycine, acetoxine, chloracetamide, nitroguanidine, and formamide. The solution should be of pH=2--4,5 when the stabilizer is added, and will be stable between the limits pH=2--7.  If the solution is outside the limits pH=2--4,5 it may be brought to this condition before adding the stabilizer, or if between pH 4,5--7 it may be heated to a suitable temperature and then treated with the stabilizer.  The stabilized solution attains its maximum stability after about 12--13 hours at 20 DEG  C. or more quickly at higher temperatures, and this maximum stability should be attained before the solution is allowed to reach low temperatures.  The stabilizers may be added to formaldehyde solutions which have already been partially stabilized by methyl or ethyl alcohol.  The stabilized formaldehyde may be used, for the production of synthetic resins for instance by reaction with urea and if urea is employed as stabilizer it will react in the resin synthesis.

Abstract: 677,618. Liquid and gaseous fuel burners. LUNDBERG, K. H. F., and LUNDBERG, K. E. Dec. 23, 1949, No. 32943/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 2, 1950.] Class 75(i) In a liquid or gaseous fuel burner having a tubular casing provided with a air inlet and an axial air outlet, a tubular fuel member arranged axially within the casing and a nozzle member which serves as an air outlet valve, the nozzle member has a number of circumferentially spaced, longitudinally extending tangential slots in which are slidably mounted guide plates which can be projected a variable distance from the nozzle member when in various positions relative to the air outlet so as to form a series of tangentially-disposed channels in the space between the burner casing and the nozzle members to control the rotating or swirling motion of the air blast issuing through the air outlet and mixing with fuel discharged through the nozzle member. The apparatus comprises a casing 1 having an air inlet 2 and a tapered nose 3 forming an air outlet, a tubular fuel supply member 6 formed at its rear end with a double conical portion 7 held in position between conical seats 8, 9, connected by a nut 11, a fuel nozzle and valve member 13 attached to a sleeve 12 slidably mounted on the member 6 and formed at its rear end with a semi-cylindrical portion 26 formed as a rack which engages with a toothed shaft 28, Fig. 3, the member 18 having a number of plates 22 slidably mounted in slots 21 formed in the member 13 these plates being attached at their rear ends to an annular member 23 slidably mounted on the sleeve 12 and formed at its rear end with a sleeve 24 having a semi-circular rack portion 27 which engages with a toothed shaft 29. Rotation of shaft 28 moves member 13 to close the air outlet or vary the area of the annular air passage formed between member 13 and the inner wall 3<SP>1</SP> of the nozzle casing 1. Rotation of shaft 29 moves plates 22 in an axial direction relative to the air outlet to vary the amount by which the plates 22 project into the annular air passage. When plates 22 are in the fully retracted position an unobstructed annular air space is formed and this results in a narrow flame of great length; when the plates 22 are in the fully forward position, i.e. abutting wall 3<SP>1</SP>, maximum rotation of the air blast, impinging on the oil supplied through passages 17, 18 and 19, is set up and this results in a flame in the shape of a slightly conical shaped disc close to the burner outlet. Fuel passages 17, 18 and 19 may be cleaned, on opening a valve 50, by passing compressed air through passageways 45, 46, 48 and 49 and intervening groove 47 on the double coned rear end of the fuel tube 6.
