Abstract: 1,143,605. Door stops. METALFORM Ltd. 1 Sept., 1967 [9 Sept., 1966], No. 40330/66. Heading E2X. A door stop comprises a member 2 which is axially rigid in compression but laterally resilient and means 3 for attaching the stop to a skirting board or dado of the wall of a room so as to project substantially horizontally therefrom. In the construction shown the member 2 is a tightly wound helical spring and the member 3 consists of a screw threaded portion 3a for screwing it to the skirting board or dado, a radial flange portion 3b, a portion 3c of hexagonal or other non-circular cross section and a shank portion 3d which engages in the end portion of the resilient member 2; the means 3 as shown is a one piece member and the shank portion 3d is screw-threaded, but in a modification the means 3 is made in two parts, one part consisting of the screwthreaded portion, the shank portion for engaging the spring 2 and an intermediate portion, which is splined to fit into a correspondingly splined bore in a portion 3e having the flange and the non-circular portion. In another modification the shank portion is threaded into the non circular portion and the screw portion is constituted by part of a wood screw. The shank portion engaging the spring need not be screw threaded but can be plain and the portion 3a for screwing into the skirting board or dado can be omitted and instead the flange portion can be provided with circumferentially spaced holes for screws. Alternatively the flange portion 3b can have its under surface coated with adhesive or it can be made in the form of a suction cup. The free end portion of the spring is provided with a rubber buffer 1 and the spring can taper in both directions from an intermediate position to reduce its lateral resiliency and hence make it more flexible.

Iron (III) - glycerin - hydroxycarboxylic acid complexes are prepared by mixing in an aqueous medium an iron (III) compound, glycerin and a hydroxycarboxylic acid, and adjusting the pH of the reaction mixture to a value of at least 5. Preferably the pH of the reaction mixture is 5-8 and the mol. ratios of the iron (III) compound: glycerin: hydroxycarboxylic acid are 1: ¢- 10:1/3-3. The iron (III) compound may be ferric chloride, ferric sulphate or an iron (III) hydroxycarboxylic acid salt such as ferric citrate. The hydroxycarboxylic acid reactant may be tartaric acid, citric acid, malic acid or gluconic acid, either in its free form or in the form of a ferric salt. The complexes may be modified by mixing the reactants and adjusting the pH to 5-6 and then adding natural or depolymerized inulin to the reaction mixture and readjusting the pH to a value of 7 to 8 to give an inulin modified complex. Pharmaceutical compositions contain the above novel iron (III) complexes in aqueous solution with an iron content of 5-100 mg./ml. of solution. The solution may contain a resorption retarding agent such as polyvinyl pyrrolidone. The solutions may be produced in ampoules for parenteral administration.

Abstract: 1,238,829. Road traffic signals on vehicles; lamp failure indicators. ROBERT BOSCH G.m.b.H. 19 June, 1970 [20 June, 1969], No. 29814/70. Headings G4F and G4N. [Also in Division H3] A flasher unit for vehicle direction indicator lamps 24, 25 and 26, 27 comprises an astable multivibrator having two emitter-coupled transistors 10, 11, the operating frequency of the multivibrator varying in accordance with the potential applied to the collector of the transistor 10. This potential is made to depend upon the load current taken by the indicator lamps so that if one of a pair 24, 25 or 26, 27 is defective, the fault is indicated by an increase in the operating frequency. Flashing is initiated by actuation of indicator switch 28 and the simultaneous closure of ganged switch contact 22. The transistors 10, 11 become alternately conductive and since the collector of the transistor 10 is coupled through a transistor 37 to a threestage amplifier 32, 34, 35 a relay 31, connected to the amplifier output, is repeatedly energized at the multivibrator frequency to operate contacts 29, 30 and cause flashing of the lamps. The potential applied to the collector of transistor 10 from the positive line U B  equals the volt drop across a resistor 17, this resistor together with a resistor 18 and switch 19 constituting a voltage divider. Thus, if switch 19 is closed there is a smaller volt drop across resistor 17 and the potential of the collector of transistor 10 is reduced whereby the multivibrator operating frequency is increased. With reference to Fig. 3 (not shown), there is described how switch 19 is closed upon failure of one of the indicator lamps, the switch 19 and also switch 22 being constituted by semi-conductors. The unit is intended for monolithic integrated circuit construction.

Skidding of the front wheels 10 of the vehicle may be detected by a tachogenerator 48 the output signals of which are differentiated and fed to a bi-stable multivibrator which emits a release signal to a three-way solenoid valve placed in a conduit 50 leading via conduits 52, 54 to actuators 24, 28 for the front wheels and via a restrictor 102 in a conduit 100 to the inlet 98 of a load responsive actuator 68. Actuator 68 has a spring 82 biased plunger 76 connected via a rod 78 and linkage 106 fixed to the vehicle body 110, and also has a rod 72 which rotates a shaft 66 when the length of the actuator is varied. Shaft 66 controls a valve 58 to either increase the pressure supplied to rear wheel cylinders 32, 36 via conduits 56, 64 or cause pressure to be vented via exhaust port 62. In normal braking pressure fluid passes to conduit 100 through restrictor 102 and enters actuator 68 through port 98 thereby moving plunger 76 leftwardly shortening the length of actuator 68 and causing shaft 66 to rotate clockwise thereby increasing the braking force on the rear wheels. If skidding occurs antiskid device 46 releases pressure applied to the front brakes through conduit 50 and there is a consequent pressure drop in conduit 110 and actuator 68, causing lengthening thereof under the action of spring 82 leading to anticlockwise rotation of shaft 66 and release of pressure to the rear brakes.
