Title: Improvements in or relating to dispersions of fluorine-containing polymers
IPC: C09D127/18
Filed: 1948-05-21
Abstract: An aqueous colloidal dispersion of polytetrafluorethylene containing a water-soluble surface-active agent is admixed with a hydrous oxide sol containing 5 per cent to 50 per cent of oxide based on the polytetrafluoroethylene.  The colloidal particles present have a size in the range 0.2 to 1 micron.  The hydrous oxides are selected from the Group III and IV elements which form colloidal hydrates, dehydrate at less than 300 DEG  C. to refractory solid oxides, and are insoluble in water, e.g. hydrated silicon or titanium dioxides, aluminium and zirconium oxides.  The silica sols may be stabilized with 0.1 per cent to 1 per cent of an alkali metal hydroxide.  The surface-active agents are preferably anion-active for silica and cation-active for alumina and may be (a) alkali metal or ammonium salts of long-chain carboxylic or sulphonic acids or sulphate esters, e.g. an alkyl sodium sulphate derived from coconut oil alcohols; (b) salts of long-chain amines or quaternary ammonium bases with a long-chain alkyl group, e.g. dodecylamine acetate; or (c) non-ionic types such as polyalcohols, polyglycol ethers or vegetable gums.  In an example (4) a colloidal dispersion of polytetrafluoroethylene containing dodecylamine acetate and alumina sol is coagulated with ammonium bicarbonate, the precipitated floc filtered and peptized by addition of acetic acid to a pH of 5.6, after which the dispersion is concentrated by evaporation.  The dispersions may be coated on to copper wire or glass and baked.  Specifications 572,265, 583,418, 584,851, 599,580 and 631,504 are referred to.

Title: Improvements in multi-roll paper calenders
IPC: D21G1/00
Filed: 1921-05-20
Abstract: 163,668. Sch³rmann, C. May 20, 1920, [Convention date]. Calendering.-In multiroll paper calenders, having 8 to 14 rolls, either or both the usual top and bottom hard cast-metal rolls are replaced by resilient or elastic (paper or cotton) rolls a, a<1> having steel shafts, and the drive is effected from the second or fourth roll b or b<1>. The total number of hard rolls is reduced by 1 and the number, of elastic increased by 1. Where the drive is from the fourth roll, it is desirable to drive the second roll therefrom with a slight lead, in order to maintain the tensile stress in the paper and prevent tearing at the driving-roll. The rolls may be slightly staggered as shown. Specification 7992/11 is referred to.
Patent GB-1139066-A (GB)
Title: Improvements relating to pulse radar apparatus
Inventor: VOLES ROGER
IPC: H03B9/10
Filed: 1965-04-02
Abstract: 1,139,066. Pulse radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. 4 April, 1966 [2 April, 1965], No. 14198/65. Heading H4D. In normal magnetron powered pulse Doppler radars the phase of the output of the coherent local oscillator 8, Fig. 1, is locked with each oscillatory burst from the magnetron 1. When very short pulses are used however such locking is difficult and the invention overcomes this difficulty by phase-shifting the output of the oscillator 8 in dependence on the departure of the output of the magnetron from an in-phase condition with the like frequency output of a stable local oscillator 5. A phase measurer 6 determines the phase difference # between a bled-off portion of the magnetron output and the output of the oscillator 5 and feeds a correcting signal to phase-shifter 16. The output of oscillator 8 is thus phase-shifted from sin(#t) to sin(#t+#). The echo signals are converted to I.F. signals in mixer 11 by means of a signal produced by mixing in mixer 9 the outputs of the two oscillators. After I.F. amplification the echo signals are coherently detected in detector 15 using the output of the phaseshifter. One example of phase-shifter 16 and phase measurer 6 is shown in Fig. 2. The output of the magnetron is compared with that of the oscillator 5 in mixer 20 to produce an output representing A sin #. When the oscillator output is phase-shifted by 90 degrees at 22 the output of a second mixer 21 represents A Cos #. The two outputs are held in respective stores 23 and 24 for the ensuing return period and are amplitude modulated in respective modulators 25 and 26 quadrature outputs B Cos#t and B Sin#t of the oscillator 8. The two amplitude modulated signals are added in 28 to produce the required phase shifted signal AB Sin (#t + #) To allow easier storage of the mixer 20, 21 outputs, the outputs may be converted into digital form and stored in digital stores with digital to analogue converter outputs (Fig. 3).

Abstract: 998,123. Hand drills. ROBERT BOSCH G.m.b.H. April 13, 1962 [April 14, 1961], No. 14364/62. Headings B3C and B3N. [Also in Division H2] An electric hand drill incorporates induced air cooling means for the motor which comprises a fan 22 at the drive end of the armature shaft 14. In operation the fan produces an air flow between the armature 12 and the stator 11 by drawing air through inlet slots 27, 28 at the rear end of the housing 10 near the handle 26. Air entering the inlet slots passes through an adjacently mounted air guiding disc 40 which has holes 47, 48 extending in a peripheral direction and which is close fitting in the housing 10. Guide vanes 50, 51 at the edge of the disc extend axially from the disc but are slightly inclined to motor axis so as to direct the cooling air through the clearance between the armature and the stator. The cooling air subsequently passes through a central aperture in the wall 24 of the insulating ring 25 to outlet openings 29 in the motor housing.
