Patent GB-1065682-A (GB)
Title: A device for indicating pneumatic tire pressures of motor vehicles
IPC: B60C23/04
Filed: 1964-04-08
Abstract: 1,065,682. Tyre pressure indicating devices. O. NECKER. April 8, 1964 [April 9, 1963], No. 14589/64. Heading B7C. [Also in Division H2] A device for indicating pneumatic tyre pressures comprises a switch mounted in a vehicle wheel and having a diaphragm exposed to the internal tyre pressure and a leaf spring which bears on the diaphragm and on a fixed abutment adjustably secured in the switch housing so that displacement of the diaphragm causes the leaf spring to act on a series of electrical contacts, the switching position of that portion of the leaf spring which acts on the contacts being dependent on the position of the diaphragm and independent of the centrifugal force due to rotation of the wheel, the device further comprising electrical connecting means including a commutator and means for indicating the tyre pressure as the switch contacts are operated. The switch is incorporated into an electric circuit (Fig. 1, not shown) in which the leaf spring is represented by contact arm (20) and the switch contacts by numerals (21), (22), (23), the switch housing being indicated by the broken line (11). The circuit includes resistors (24), (25) connected to a slip ring (14), (15) so that as the arm (20) moves from right to left of Fig. 1 with increase in tyre pressure loss the signal given by a lamp (17) mounted on the dashboard of the vehicle changes from a dim to a bright light and then to a flashing light. In the embodiment of the switch shown in Fig. 10 the leaf spring 20b is substantially U-shaped and its lower limb 44 is supported on a screw 50a which is axially adjustable to vary the initial stress of the spring. The contact arm (21) is formed by a pin 21a which may be a permanent magnet to damp natural vibration of the spring 20b. The free end of the upper limb 43 of the leaf spring carries a contact element 47 which overlies the pin 21a and co-operates with contact springs 22a, 23a spaced above the element 47. With increase in pressure loss the limb 43 of the spring 20b moves so that the contact element 47 engages the spring 22a, and with further loss causes the spring 22a to contact the spring 23a, thus setting up the required circuits shown in Fig. 1. In a modification the initial stress of the leaf spring is varied by a central pin which is secured against axial displacement and carries an eccentric stud for engagement with a slot in the lower limb of the leaf spring. In a further embodiment (Fig. 3, not shown) the leaf spring is a buckling spring (20) arranged radially with respect to the wheel, the switching movement of the electrical contacts being effected substantially at right angles to the spring on movement thereof with change in tyre pressure.

Title: Knots and methods of forming the same
Inventor: SHORTLAND ARTHUR
IPC: B65H69/04
Filed: 1951-06-26
Abstract: 702,348. Knots. MELLOR, BROMLEY & CO., Ltd. June 6, 1952 [June 26, 1951], No. 15148/51. Class 112 A knot suitable for mechanically tying together at least two ends of any kind of yarn is produced by a method which includes making at least one loop of one or both yarn ends with' the aid of. a hooked instrument, drawing through the loop, by the instrument, a further loop, or the first of a plurality of successively interengaged loops, of either or both yarns, and manipulating the instrument to engage either or both of the yarn ends and pull it or them through the lastformed loop. In Fig. 13 the yarn 2 has been engaged by a latch needle which has then been rotated to form three loops 7, the needle has then been projected through the loops to engage another part of the same yarn and draw it through the loops to form a loop 8, and the end cf the other yarn 1, initially laid parallel to the yarn 2, has been similarly drawn through the loop 8; the ends of the yarn 2 are now to be pulled, to form the knot by drawing the loop 8 out of the loops 7 and thereby drawing a loop of the yarn 1 into the loops 7, and the knot is then tightened by pulling on both yarns. The yarn 1 is preferably trimmed before being drawn into the loops 7. The number of loops 7 may be reduced to two or one, and a single loop may be twisted if desired. Two knots may be formed back to back a short distance apart on the same yarns. In a modification, instead of drawing the end of the yarn 1 through the loop 8 a second similar loop of either or both of the yarns may be drawn through the loop 8 and may be followed by a further similar loop or loops before the end of one or each yarn is pulled through the last loop to complete the concatenation, the knot then being formed and tightened as before. Specification 702,347 is referred to.

Title: Artificial filaments
Inventor: GORDON MANFRED
IPC: B29D99/00
Filed: 1950-06-17
Abstract: Filaments of the product made by cyclizing rubber dispersed in a hydrated sulphuric acid medium, e.g. the cyclized rubber made from latex in accordance with Specification 634,879, are stretched at a temperature, e.g. 90-110 DEG C, at which the product is rubbery, and are cooled in the stretched state to a temperature at which the product is not rubbery.  Monofils are made by continuously delivering a tape of the cyclized rubber into a region maintained at stretching temperature, continuously withdrawing the hot tape from this region and concurrently twisting the tape and stretching it, e.g. to 5-6 times the original length.  The tape so treated may be prepared by depositing an aqueous dispersion of the cyclized rubber on a travelling belt, drying the dispersion on the belt to a powdery deposit, and conveying the deposit through the vapour of a volatile liquid, e.g. of carbon disulphide, which swells the cyclized rubber and causes the particles of the deposit to coalesce to a coherent film.

Title: Improvements in or relating to electric signalling and/or control systems
IPC: G08C19/48
Filed: 1937-06-04
Abstract: 500,468. Electric signalling and control systems. SPERRY GYROSCOPE CO., Inc. June 4, 1937, No. 15562. Convention date, June 6, 1936. [Class 40 (i)] In an electric system for transmitting data or controlling apparatus, the signals are transmitted over a twowire line, e.g. a telephone line, by means of a voltage the phase of which is variable relatively to a timing voltage applied to the same lines. As shown in the Figure, the transmitter 1 and receiver 2 are connected by a pair of wires 7 which are supplied at the receiver by a single-phase timing voltage produced by a generator 4<1>. At the transmitter, this timing voltage is transferred through a selecting and frequency discriminating network 14 to a frequency-doubler 15 and a network 16 which converts the single-phase voltage into three-phase voltage for supplying a selsyn type transmitter 17, 34. The winding 34 of the transmitter is connected through an amplifier 18 to the line and is adapted according to its relative position to vary the phase of its output voltage relatively to that of the timing voltage. At the receiver the network 6 passes the double-frequency voltage to a phase detector 19 which is also supplied through a selsyn apparatus 20 from a double-frequency threephase voltage generated by the equipment 411. The detector 19 operates a central zero instrument 24 and the arrangement is such that when the transmitter is operated, the phase relations of the two selsyns are varied and the instrument 24 is operated in one or other direction. The instrument is restored to zero reading by operation of the receiver selsyn, the amount of movement thereof corresponding to the movement of the transmitter. In a modification, the receiver selsyn is operated automatically by a motor controlled by a phase-detector which affects the gain of modulater valves adapted to control the operating valves of the motor. The input to the operating valves may be modified in accordance with the back EMF of the motor in order to prevent hunting. In a further modification a plurality of transmitters is associated with corresponding receivers over the same pair of line wires by the use of additional frequencies.

Title: Condensation products of acroleins with aliphatic primary alcohols
Filed: 1951-07-02
Abstract: Beta-aliphatic oxy-propionaldehydes are prepared by heating acrolein and a primary aliphatic alcohol, free of groups reactive with acrolein other than hydroxyl, in the liquid phase in the presence of a mixture of an alkaline reacting amine and a carboxylic acid, or of an amphoteric amino compound, in an amount sufficient to maintain the pH of the resulting reaction mixture between 5.9 and 7.5. Acetalization and aldolization are thereby avoided.  The amines may be primary, secondary or tertiary aliphatic, aromatic or heterocyclic; the amphoteric amino compunds are amines of the above classes containing an acidic hydrogen atom connected to carbon through an oxygen atom and these compounds may also be used with carboxylic acids.  Reaction may be effected by refluxing at ordinary or raised temperature; preferably an excess of the alcohol is used; polymerization inhibitors such as hydroquinone may be present. Examples describe the production of (1) beta-ethoxy propionaldehyde from ethanol and acrolein using diethylamine-formic acid, triethylamine-formic acid, diethylene triamine-succinic acid, triethanolamine - formic acid, para - aminophenol - acetic acid or aniline-acetic acid mixtures for pH adjustment; (2) beta-methoxy propionaldehyde from acrolein and methanol using triethylamine-formic acid, diethylamine-propionic acid, glycine or para-aminophenol for pH adjustment; (3) beta-butoxypropionaldehyde from butanol and acrolein; and (4) beta-ally-oxypropionaldehyde from allyl alcohol and acrolein, both in presence of diethylamine and formic acid for pH adjustment. Other examples of alcohols, amino compounds and acids include pentyl, hexyl and octyl alcohols, methoxyethanol, ethylene glycol, diethylene glycol, propylene glycol; methyl amines, propyl amines, butyl amines, ethanol amines and their homologues up to heptanol amines, phenylene diamine, beta-alanine, anthranilic acid; heptanoic, octanoic, oxalic and benzoic acids.
