Title: Improvements in or relating to windscreen wipers
IPC: B60S1/42
Filed: 1948-12-22
Abstract: 685,307. Windscreen cleaners. O'SHEI, W. E. Dec. 22, 1949 [Dec. 22, 1948], No. 32352/49. Divided out of 685,291. Class 138 (i). A connector for a windscreen wiper blade and wiper arm, comprises a pair of spaced members or ears having apertures through which extends a pin, the ends of which project beyond the outer surfaces of the members or ears, the pin being surrounded by or associated with one or more springs, preferably helical, which urges or urge the pin into a normal position in which its ends project beyond both members or ears, at least one of the said projecting ends being free to move inwardly longitudinally against the action of the spring or springs. In the embodiment shown in Fig. 1 a pin 7 having a collar 7a is mounted, for longitudinal movement in one direction only against the action of a helical spring 6, in ears 1, 3 upstanding from the back of the blade 2. The ear 1 is fixed to a channel member 16 secured to the blade by a rivet 17, or sprung thereover, while the ear 3 is movable relative to the ear 1 against the action of the spring. The ear 3 forms one limb of an L- shaped member, the other limb 4 of which'has a slot 18 engaging the stem of a T-shaped member 15 stamped-up from the back of the member 16. A housing 12 attachable to a wiper arm 11 is pivotally connected to the pin 7. The blade may be moved angularly with respect to the arm the slot 18 allowing the ear 3 to pivot at 5 and to move towards the ear 1, against the action of the spring which tends to restore the parts in alignment with the blade. A rivet may be used in lieu of the T-shaped member. If desired angular movement of the blade to only one side of the normal position may be provided by stop or other means. The movable ear may be dispensed with and the spring 6 would then bear at one end on the fixed ear and at the other end against the remote end wall of the housing. In a different form of the invention, Fig. 5, both ears 1, 1a are fixed to a channel member 16a and a collar 7a is provided on the pin 7. The blade can rock in the housing 12a so as to incline to a trailing position as the blade moves over the windscreen and this movement is limited by the ears engaging the side walls of the housing. In order to facilitate assembly of the pin in the housing the end walls of the housing are formed with leading-in portions 19. The housing is provided with two openings 21, 23 of different widths to accommodate standard arms. In a modification, Fig. 7, the pin 27 is provided with a central collar 7b and two springs 26. With the constructions described the housing is reversible and if the blade fitting is off-centre of the length of the blade, the length by which the blade projects from the arm can be changed by reversing the housing on the fitting. The pin described with reference to Fig. 1 may be replaced by the pin and springs described in Fig. 7. Specification 523,177 is referred to.

Title: Improvements in and relating to liquid-containing tanks and to fuel-supply means for internal combustion engines
IPC: F02B1/00
Filed: 1936-11-26
Abstract: 484,819. Supplying carburetters. DAWSON, A. E. Nov. 26, 1936, No. 32368. [Class 21] [Also in Group XXIX] The main or auxiliary supply to the carburetter of an internal-combustion engine is provided by gravity from an auxiliary container 10, Fig. 1, which is itself supplied from a main tank by means of an electrical pump, the supply into the auxiliary container being controlled by a valve actuated by a diaphragm moved by the pressure within the auxiliary container. In one form, fuel is admitted through an opening 11, Fig. 1, vent air passing through an opening 24 and pipe 29. When liquid obturates port 24, diaphragm 13 rises and raises valve body 19, 21 so that pin 25 closes opening 24 and stops inflow through opening 11. In a modification, contact between rods 16, 25 is by means of a spring stud mounted in the end of rod 16. In another form, an inlet valve 33, Fig. 3, is closed when liquid reaches diaphragm 13 by links 36, 37, vent air emerging through openings 39, 30. This form may be provided with a valve similar to that previously described. If fuel oil emerges through pipe 29 it may be collected. The pipes which lead to the carburetter from container 10 may communicate with different levels within the container so as to provide an emergency supply. Filters may be arranged at the lower end of the valve chamber and also at the inlet and vent.

Patent GB-850861-A (GB)
Title: Improvements in or relating to telephone bell ringing circuits
Inventor: FLOWERS THOMAS HAROLD
IPC: H04M19/02
Filed: 1955-11-14
Abstract: 850,861. Automatic exchange systems. POSTMASTER GENERAL. Nov. 14, 1956 [Nov. 14, 1955], No. 32547/55. Class 40 (4). A subscriber's bell BL is fed from an exchange battery B connected to the subscriber's line on the outgoing side of exchange switches ECS, a ringing signal being sent from a ringing generator RG at the exchange over the exchange switches to control the ringing of the bell BL by power from the exchange battery B. The arrangement is particularly intended for use with electronic exchanges, in which the switches are not suitable for the transmission of sufficient power to operate a conventional bell. As shown, a capacitor C1 in series with a magneto bell BL is normally charged to the potential of the exchange battery B. The ringing signal (audio-frequency modulated at a low frequency) is received by a tuned circuit C3, T2, demodulated by MR, C4, and applied to the emitterbase circuit of a transistor TS so as to increase the conduction between the emitter and collector which are bridged across the capacitor C1 and the bell BL, thus ringing the bell. The current drawn from the exchange battery varies the potential of a lead 4 to give a check signal to the exchange that the ringing is effective. Distortion of speech transmission by C3, T2 may be reduced by shunting the transformer T2 by a resistor R4 under the control of additional cradle-switch contacts CS3. Alternatively the cradle-switch may disconnect the circuit C3, T2 from the line. Instability due to feed-back at the transistor TS is prevented by a resistor R 1, which may be replaced by the emitter-collector path of a second transistor, Fig. 2 (not shown). In a modification (not shown), a D.C. bell is used with a series-connected transistor. Selective ringing on a party line may be effected by using different audio-frequencies for the ringing signals. A thermistor in series with the bell prevents tinkling due to dialling by another subscriber on the line.

Title: Improvements in the treatment of wool-containing garments
IPC: D06M11/54
Filed: 1963-08-22
Abstract: A wool-containing garment is crease-proofed and shrink-proofed and its resistance to fuzzing, pilling and localized cockling and puckering after laundering and air or tumble drying is improved by wetting it with an aqueous solution of a water-soluble reducing agent, the concentration of the reducing agent being in the range of 2-15% by weight and the wetting resulting in an increase in weight of the garment in the range 30%-100%, forming it into its desired configuration after wetting, subjecting it to heat and pressure and drying it.  Suitable reducing agents are sodium sulphite, bisulphite or meta bisulphite, monoethanol amine sulphite or bisulphite, ammonium thioglycolate and monoethanol amine thioglycolate.  The aqueous solution of the reducing agent may contain a wetting agent, e.g. an alkyl aryl polyether alcohol. The fabric from which the garments are made may have been stabilized against shrinkage, may be a wash-wear material prepared by combinations of chemical treatments and/or construction or it may have been presensitized by treatment with a chemical reducing agent, e.g. sodium bisulphite, and drying. After wetting with the aqueous solution of the reducing agent the garment may be placed on a garment press and steam applied at least at 30 pounds square inch gauge for 10-30 seconds, the garment press being maintained in a closed position for a further period, e.g. 45 seconds, without the application of steam and a vacuum being subsequently applied to the garment in the open press for drying. Garments made from wool in admixture with nylon or acrylic fibres may be treated.  Specified garments treated are trousers, straight skirts, pleated skirts, shirts, slacks and suit coats.
