Title: Improvements in and relating to suspensions of vehicles
IPC: B60G17/027
Filed: 1963-07-13
Abstract: 1,057,844. Vehicle suspensions. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. July 13, 1963 [July 13, 1962], No. 23095/63. Heading B7D. A suspension for a motor vehicle, which may be used on rough country and may be amphibious, comprises a helical spring 2 interposed between a wheel support arm 4 extending transversely of the vehicle and a plate 10 fast with a cylinder 9 in which operates a piston 6 connected to the vehicle frame 3 by its pistonrod 6a. The cylinder space 12 below the piston 6 is connected by a pipe 26 with a cylinder space 18 of a balancing device which comprises a cylinder 13 divided into two chambers by a partition 15, in each of which is located a piston 16, 17 respectively, mounted upon a common shaft 22 and centred by springs 25. The corresponding wheel suspension unit on the opposite side of the vehicle is connected to the cylinder space 19 and that of the wheel diagonally opposite to the space 20, the unit for the wheel on the same side being connected to the space 21, i.e. diagonally opposite suspensions are connected to non-adjacent spaces. The pipes 26, 27, 28, 29 associated with each unit are each connected through a driver controlled valve 35 with a cylinder 30 containing a piston 32 to which is applied fluid pressure in the cylinder space 33 whereby the volume of hydraulic fluid in each component part of the system associated with each wheel and thereby the height of each suspension may be adjusted. The fluid may be exhausted entirely from each cylinder 9, in which case the balancing device 13 is inoperative, or if fluid is applied to each cylinder 9 such that the pistons 6 are at the mid-positions, a balancing effect is obtained wherein, when one wheel rises due to uneven ground, say the wheel connected to cylinder space 18, hydraulic fluid will be forced into the space 18 and the pistons 16 and 17 will be moved to the right, whereby fluid will be forced out of the spaces 19 and 21, causing the associated suspension heights to increase, and will be allowed to enter the space 20 whereby the associated suspension height (of the diagonally opposite wheel) will be decreased. In a vehicle having tandem axles the suspension units for the wheels on each side of the vehicle in each tandem axle pair are interconnected by a pipe (37), and the associated cylinder spaces, in the balancer unit 13 are correspondingly enlarged. The helical springs 11 may be replaced by pneumatic or rubber springs and the suspension units may act directly or through linkage systems upon the wheel suspension arms. The suspension units may be horizontally disposed and act through levers.

Title: Improvements relating to sheathed wire electric heating elements
IPC: H05B3/48
Filed: 1957-07-22
Abstract: 864,954. Electric heating resistors. SIMS, W. J. July, 22, 1958 [July 22, 1957], No. 23123/57. 'Class 39(3). [Also in Group XXXVI] An electric heating element comprises a conductor 1 in the form of a plane zig-zag with rounded bends, a metallic sheath 2 of generally oval cross-section, compacted refractory insulating material 3 which fills the sheath and separates the conductor therefrom, and terminals 4 (see Group XXXVI) projecting from the ends of the sheath. Before the sheath is pressed to the desired oval section it is preferably of diamond shape, Fig. 5, the shorter of the inner diagonals of the diamond being of just sufficient length to permit the zig-zagged conductor 1 to be inserted into the sheath diagonally and retained therein. The soacing between the turns of the condutocr may be greater near the terminal to reduce the watts dissipation in that area. The element may be wound spirally to form a hotplate, with the flattened sides of the oval either parallel to the plane of the spiral or perpendicular thereto (Figs. 7 and 8. not shown). The spacing between the turns of the zig-zag conductor in the outer convolutions of the spiral may be reduced to increase the watts dissipation from the outer convolutions. Specifications 541,248 and 864,953 are referred to.

Title: Improvements in or relating to the manufacture of synthetic resin products
IPC: C08G8/04
Filed: 1936-08-24
Abstract: A moulding-composition is obtained by heating to a temperature of the order of 130 DEG  C. an aldehyde in aqueous solution and a phenol under pressure, with agitation and under conditions which preclude dehydration, to produce a resinous composition having the water of the reaction mixture distributed therethrough, mixing the resinous composition with a filler and working up the mixture on heated rolls &c. so as to incorporate the filler and remove the water.  Catalysts may be employed to assist the condensation reaction and the intermediate resinous product may be mixed with hardening agents, dyes, &c.  A kneader may be employed instead of heated rolls. According to examples, commercial cresol is heated with aqueous formaldehyde, with agitation, in an autoclave at a temperature of 130 DEG  C., ammonium chloride, phthalic acid or aqueous ammonia being added as catalyst; the reaction mixture is run out of the autoclave, allowed to cool under conditions which preclude distillation, mixed with fillers and worked up on heated rolls.  Resins may be similarly produced from mixtures of phenol, urea and formaldehyde; cresol, aniline and formaldehyde; phenols, aldehydes and oils, e.g. tung oil and blown castor oils. Water-soluble aldehydes other than formaldehyde may be employed.

Title: Blood glucose level monitoring-alarm system and method therefor
IPC: A61B5/00
Filed: 1973-05-16
Abstract: 1394171 Surgical implants WHITTAKER CORP 16 May 1973 23456/73 Heading A5R [Also in Divisions H1 G1 and G3] The blood glucose level of a human body is monitored by an implanted glucose diffusion-limited cell 10. A membrane 14 (materials are exemplified) which permits free transmission of oxygen and glucose &c but impedes the diffusion of large macro-molecules defines a chamber 16 within which are positioned metal catalyst coated anode 18 and cathode 20, body fluid within the chamber acting as an electrolyte. Cathode 20 has a larger surface area than the anode 18 and is covered with a thin layer of membrane 22 which allows free passage of water, oxygen &c but strongly resists the diffusion of glucose molecules so that it serves as an oxygen electrode. The anode 18 is covered with a relatively thick layer 24 of porous plastics material which impedes the diffusion of glucose. Thus the rate of oxygen molecules arriving at the cathode is always larger than the rate of glucose impingement on the anode surface and the current that can be drawn from the cell 10 is proportional to the diffusion of glucose molecules and hence to the concentration of glucose in the body fluid which is in turn proportional to the concentration of glucose in the blood. The anode and cathode catalyst materials are different, suitable materials for the anode being platinum black or group VIII transition metals and for the cathode Group Ib metals such as gold, silver Anion and/or cation exchange membrane may be interposed directly between the two electrodes to serve as a solid electrolyte as well as a partition for two half cells. Circuitry. The output current from cell 10 is after amplification 30 applied to a current to frequency converter 32 connected to a pulse code modulation transmitter 34, Fig. 3 (not shown) so that the blood glucose level signal may be transmitted to an appropriate receiver, Fig. 4 (not shown) outside the body. The receiver circuit includes a voltage comparator which compares the blood glucose level with a voltage or a range of voltages which represent a natural or desired level. If the level goes outside the range an alarm may be operated to signify the requirement of addition of glucose or insulin in a diabetic and appropriate values are actuated to add the glucose or insulin. Degradation of the platinum anode surface is counteracted by using a third biased electrode and cycling the anode from anodic to cathiodic using pulses. Instead of monitoring the output current of the fuel cell other characteristics which may be measured include the rate of potential rise in a cell on charging the temperature rise due to glucose oxidation, the change in pH value as a result of the formation of gluconic acid and the reduction of oxygen tension as a result of O 2  consumption.

Title: Improvements in or relating to circuit arrangements comprising a plurality of amplifiers
IPC: H03G7/04
Filed: 1951-10-12
Abstract: 684,909. Valve amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 12, 1951 [Oct. 17, 1950], No. 23824/51. Class 40 (vi). In an arrangement employing a number of amplifiers in parallel, in which the output of each is stabilised by means of a negative parallel feed-back operative over a biased rectifier, the input circuit of each amplifier includes an impedance inverting network. By this means the input impedance increases as the negative feed-back path becomes operative, and prevents loading the common source as would otherwise occur. A carrier applied over transformer 11, Fig. 4, to a valve 10 is fed out through transformer 12 to a load and over winding 17 to a rectifier 13 biased by battery 14. When the output is sufficiently great the rectifier conducts and applies feed-back to the grid of the valve 10. Inductor 19 and capacitor 20 act as an impedance converting arrangement so that the decrease in impedance due to the feed-back is caused to appear as an increase in the load impedance presented to the input source. In a modification, Fig. 5, two inductors 21, 22 and two capacitors 23, 24 are used. In a further modification, Fig. 6 (not shown), the input transformer is centre-tapped and connected to one input lead, the other being connected through a capacitor to one end of the primary and through an inductor to the other end. The winding 17 may be on a current transformer, Fig. 7 (not shown), when it is desired to maintain the output current constant. A push-pull arrangement is also described, Fig. 8 (not shown).

Abstract: 952,617. Tunnel-diode frequency changing circuits. RADIO CORPORATION OF AMERICA. July 7, 1960 [July 20, 1959], No. 23834/60. Heading H3T. A frequency changer comprises a negative resistance diode as the non-linear mixing element. In a first embodiment, Fig. 3, an R.F. signal is applied to terminals 36, 37 across which is connected a parallel resonant circuit 26 tuned to the frequency of the R.F. The signal from the local oscillator 44 is applied to a second resonant circuit 28, comprising an inductor 42 and the capacitance of a tunnel diode 20, which is tuned to the local oscillator frequency, and the I.F. output is derived from a third resonant circuit 30, tuned to the frequency of the I.F. signal. The diode 20 is biased to its negative resistance region by a battery 22 and resistor 24. For stability the positive conductances of each resonant circuit exceeds the negative conductance of the diode 20. If the positive conductance of the circuit 28 is made less than the negative conductance of the diode, the local oscillator 44 may be omitted, and the circuit functions as a self-oscillating mixer, Fig. 4 (not shown). In a further embodiment the parallel circuits 26, 30 are replaced by series resonant circuit in series with the input and output terminals, Fig. 5 (not shown), and in another the three parallel resonant circuits are connected in series with each other, Fig. 6 (not shown). In Fig. 7 the local oscillator and R.F. signals are fed over lines 124, 126 to a resonant cavity to which is connected diode 114 and the I.F. output is taken from tuned transformer 130. Fig. 8 shows a coaxial line mixer in which the resonant circuits for the R.F. and local oscillator signals are provided by tuner stubs 144, 146 and 152, 154, the I.F. output is taken from the diode 160 by a further coaxial line 168 which is tuned by any suitable lumped circuit. In another embodiment, Fig. 9, R.F. and local oscillator signals are fed via a coaxial line 170 to one end of a quarter-wave resonant line having parallel conductors 174, 176, which is broadly tuned to respond to both signals. The diode 178 is mounted at the opposite end of the line, and the I.F. output taken from a tuned circuit 186. Specification 952,616 is referred to.
