Title: Disc brakes for vehicles
Inventor: DAVIS JOHN WALTER
IPC: F16D55/228
Filed: 1955-08-19
Abstract: 801,805. Disc brakes. GIRLING, Ltd. Aug. 15, 1956 [Aug. 19, 1955], No. 23918/55. Class 103 (1). In a " spot-type " disc brake of the kind in which the friction pads can be inserted and removed through an opening in the radially outermost side of the calliper as disclosed in Specification 742,338, the friction pads are mounted in a housing which may be removed or inserted through an opening in the radially outermost side of the calliper. In the embodiment illustrated in Figs. 1 to 5, the friction pads 23 of the " spot-type " disc brake are located together with their back plates 24 in a housing 15 formed as a skeleton rectangular frame, as shown in Figs. 4 and 5. The friction pads 23 are of segmental outline and are secured to backing plates of such an outline and dimensions as to be a sliding fit in the housing 15 which is itself a sliding fit in opening 14 in the calliper so that when the brake is applied the torque on the pads is taken through the housing by the stationary calliper. The outer end of housing 15 has welded to it a rigid cover plate 19 provided at each end with holes to receive bolts 20 securing the housing to the calliper. When the pads have been worn to a minimum thickness the complete housing is withdrawn through the outer end of the opening 14 after removal of bolts 20 and another housing with new pads inserted or new pads fitted to the same housing which is then replaced. As the friction pads wear, the pistons advance in the housing and opposed notches normally closed by rubber plugs 27 are provided in the cover plate 19 through which a tool can be inserted to push the pistons back into the cylinders when it is desired to remove the housing with the worn pads. Rubber sealing members 17 and 22 are provided to make water- and dust-proof seals.

Abstract: 672,959. Controlling aircraft. BLACKBUHS & GENERAL AIRCRAFT, Ltd. July 11, 1950 [Sept. 16, 1949], No. 23960/49. Class 4. In an aircraft of the type described in Specification 672,914 in which the sweep-back of the wings is variable and the wing roots lie within shrouds extending symmetrically along cach side of the fuselage within which the wings are pivoted outboard of the fuselage with such shrouds forming part of the wing surfaces in all positions of the wings, each wing carries an auxiliary wing surface wich is housed in a recess in that portion of the trailing edge of the wing is coutained in the shroud when the wing is swept back to an acute angle to the longitudinal axis of the fuselage and which is extended to increase the effective wing chord of that portion of the wing when the wing is swung forward to extend substantially normal to the longitudinal axis of the fuselage, Each wing, which is pivoted with respect to the fuselage about a pivot 4, is provided with a movable surface 86 is so arranged that with the wing in the spread position it completes the normal wing plan-form profile. When each wing is moved to the swept back position the inboard trailing edge portion is contained within a shroud 3 and to enable it to occupy this position the surface 86 is automatically moved forward to a. position underlying said inboard trailing edge portion as the wing moves. The surface 86 is mounted at its outboard end on a vertical pivot 87 and its inboard end is slidably supported in an arcuate track 93 and is connected to the shroud by a swinging link 90 so that rearward pivotal movement of the wing causes the inboard end of the surface 86 to move forwardly on the track 93. Each surface 86 may be used as a landing flap by the actuation of a control mechanism which causes it to rotate about an axis extending along its leading edge and further landing flaps are provided on the undersurface of each shroud 3. Provision is made to ensure that identical movements are applied to both wings when they are being moved hydraulically from one position to another. Specifications 667,911 and 672,917 also are referred to.

Title: Pressure-responsive electric switch
IPC: G01L9/00
Filed: 1961-07-03
Abstract: 932,408. Pressure switches. A. MARGERIE. July 3, 1961 [Aug. 16, 1960], No. 23966/61. Class 106 (2). In a fluid pressure responsive switch the movement of a Bourdon tube T in response to fluid pressure supplied at P is transmitted by a link B to a multi-stepped cam S pivoted at O. The cross-section of cam S is defined by a series of arcs centre 0 separated from one another by inclines. A lever L bears on an arc of the cam S and when the cam has turned sufficiently due to increased pressure in tube T, for the lever to engage an incline the lever closes a micro-switch I. If the pressure drops sufficiently for the lever L to engage the next lowest incline the switch is again opened. The position of the microswitch may be adjusted by means of a control cam G so that the microswitch can occupy a different position corresponding to each arc on cam S and the device can thus operate over several pressure ranges.
Patent GB-388426-A (GB)
Title: Improvements in the treatment and manufacture of textile materials
IPC: D06M13/188
Filed: 1931-08-26
Abstract: Artificial filaments, e.g. of cellulose acetate, are soaked in liquids comprising alkylolamines and/or their derivatives, the o -amino-alkylamides of fatty acids, di- or poly-hydric alcohol derivatives in which some of the hydroxy groups are esterified by fatty acids, or mixtures thereof, and cut into staple lengths while still wet.  The treatment is stated to remove difficulties due to electrification of the fibres and slipping of the fibres over one another.  Suitable substances are mono-, di-, or triethanolamine, propanolamine, dioxypropylamine, hydroxy-ethylaniline, and the salts, soaps, esters, or acid amides of such compounds with higher fatty acids, e.g. capric, lauric, myristic, oleic, and stearic acids; also glycerol mono-oleate, glycerol di-oleate, ethylene glycol mono-oleate, diethylene glycol mono-oleate, or the corresponding esters of stearic, palmitic, or ricinoleic acid.  Solutions of ethanolamines in paraffin oils are particularly mentioned.  The hanks &c., drained to contain about their own weight of liquid may be cut in this condition and dried, the drying being preceded if desired by a centrifuging operation to bring the liquid content down to about 30-40 per cent.  In the latter case a more concentrated alkylolamine &c. solution is used.  Roughening media such as silica, barytes, lithopone, kieselguhr, or the soluble salts of Specification 372,797, and also a lubricant, e.g. olive oil, may be applied conjointly with or separately from the alkylolamines or the like. The bodies applied to the fibres may be removed immediately after spinning, or may be removed by the usual scouring operation applied to the fabric.  The process may be applied to yarn consisting of one kind of fibre only, e.g. cellulose acetate yarn, or to mixtures of fibres, e.g. mixtures of cellulose acetate fibres with viscose, silk, cotton, or wool. Specification 388,427 is referred to.

Title: Warning systems for load handling equipment
Inventor: KEZER CHARLES F
IPC: B66C23/90
Filed: 1972-05-23
Abstract: 1334341 Selective signalling LITTON INDUSTRIES Inc 23 May 1972 [25 May 1971] 24287/72 Heading G4H A warning system for producing a warning signal indicating a condition of failure or approach to failure of load handling equipment, comprises signal input means to provide input signals representing actual operational parameters of the equipment, a memory for storing digital data pertaining to discrete operational limits of the equipment, selecting means for selecting from the memory a portion of the stored data in dependence upon at least one of the operational parameters, and comparator means operable to compare the selected data with at least two others of the operational parameters, without interpolation between the discrete values of the selected data, to produce a warning signal when the compared data have a predetermined relation. A crane having an extendable, elevatable boom is mounted on a truck, with extendable outriggers (or &c.) for improved lifting capacity. The operator indicates, on digital switches, the boom length, and whether the outriggers are extended or retracted, and this information selects a portion of a read-only memory. The portion selected may also depend on the quadrant in which the boom is operating and/or the type of counterweight being used. An increasing series of boom angles are read from the selected portion of the memory in turn, stored in a register, converted to analogue form and compared with an analogue voltage from a pendulum potentiometer representing the actual boom angle. When the latter is reached, a maximum boom load value associated with the angle value reached is inserted into a register, converted to analogue form and compared with the actual boom load value sensed by a load cell. If 85% of the maximum value is reached, a lamp is lit, and if the maximum value is reached, another lamp is lit and a buzzer is sounded. The alarm is also given if the actual boom angle is less than the smallest or greater than the largest boom angle from the memory. The actual boom angle is indicated on a meter. In a modification, the per cent of maximum load reached is displayed from the output of a high-gain differencing amplifier fed with the actual boom load and the output of a further digital-to-analogue converter fed with the maximum boom load from the register, the output of the amplifier also providing a reference level for the further digitalto-analogue converter. In another modification, a zero-correction from the memory is registered, converted to analogue form, and subtracted from the actual boom load, the result acting as the reference level in a digital-to-analogue converter fed with a reciprocal slope value from the memory, the converter output being displayed as the actual lifted load. A test button causes reference voltages to be applied to the system to test the lamps and buzzer.
