Title: Improvements in and relating to the preservation of rubber
IPC: C08K5/37
Filed: 1945-02-23
Abstract: The deterioration of rubber is inhibited by incorporating therein a small proportion of a secondary aromatic amine antioxidant and a small proportion of a terpene mercaptan or a terpene mercaptide of a metal of Group II-B of the Periodic table. Specified terpene mercaptans are those of pinene, camphene, sylvestrene, limonene, carene, phellandrene, bornylene, selinene and fornesene, which may be made by the methods described in Specification 580,366, [Group III], and U.S.A. Specification 2,076,875.  From 0.01 to 2.0 per cent. of the mercaptan or mercaptide, and 0.2 to 2.0 per cent. of the antioxidant by weight of the rubber may be used, preferably 0.2 to 1.0 part of the mercaptan or mercaptide is used per part of antioxidant.  These ingredients may be added separately to the rubber, but are preferably compounded to form an antioxidant composition. Examples are given showing the effect on the rate of ageing of a standard rubber mix to which has been added 4, 41 dimethoxy diphenylamine, of various quantities of pinene mercaptan, and the pinene mercaptides of zinc cadmium and mercury.  These results are contrasted with similar mixes to which copper silver, lead and cobalt pinene mercaptides are added.  Other secondary aromatic amines that may be used include N phenyl a -naphthylamine, N phenyl b -naphthylamine, diphenylamine, the alkoxy diphenylamines, the alkenoxy diphenylamines, the alkoxy phenylnaphthylamines, the alkenoxyphenyl-naphthylamines, N : N1 diphenylpara-phenylenediamine and N : N1 diphenyl benzidine.

The control member 111 and guide 113 may also be removed and arranged in the part 62. The hopper is releasably attached to the frame of the implement.
Patent GB-101588-A (GB)
Title: Improvements in or relating to Machines for Filling and Sealing Bottles.
Inventor: KAYE SAMUEL
IPC: B67C7/00
Filed: 1916-03-30
Abstract: 101,588. Kaye, S. March 30, 1916. Bottling; capsules, applying.-In a revolving-table machine for filling and sealing bottles, the filling and sealing heads travel in a circular path, and the cap-pins, to which the bottle-caps are fed from a hopper, travel in and out of this circular path. The filling and sealing heads 15, Figs. 2, 5, and 6, are supported by rods 8 from hangers 6 depending from the axles 5 of wheels 4, which travel between parallel tracks 3 secured to uprights 1. The tracks 3 are circular in plan and undulating in elevation, and in the annular the rods 8 pass through openings in the annular header 11 and the guide 12. Connexion between each rod 8 and its head 15 is made by a counterbored screwed plug 16, so that the capacity of the head can be varied without altering its elevation. The capacities of the heads 15 and the bottles to be filled are made to correspond. The carbonated water is supplied to the heads through spring-pressed valves 32 by hose 23 from an annular channel 22 in the header 11. Radial ducts 24 connect the channel with branch pipes 25 leading from a swivel 26, which turns upon the fixed supply-pipe 27. The valve 32 is operated by a trip-lever 35 pivoted to the guide 12 and connected by a rod 37 to the valve-operating lever 38. When the lever 35 is pushed aside by a bottle entering the head 15, the lever 38 is moved to the opposite side of a cam-track 40 and the valve 32 opened. The rubber ring 41 which clamps the bottle neck is compressed between its cap 42 and a flange 43 to form a tight connexion with the bottle neck. The cap 42 is carried by links 46 from bell-crank levers 44, which are pivoted to the head 15 and carry rollers 48 engaging a cam-rail 49. The bottle-caps pass from the hopper 51 by a shoot 53 to a position over the path of the cap-pins 54. A channel 80, Fig. 7, in the hopper has a groove in the bottom of one edge to receive the flange of a cap, and a sweep 82 removes any caps incorrectly placed in the channel. A spring-supported cup 55 on each pin 54 has two ears adapted to enter transverse or longitudinal slots in the end of the shoot 53 and remove the caps one at a time. The pins 54 are carried by slides 61 having projections engaged by the depending flange of a cam 62, which causes the pins to move in and out of the circular path of the heads 15. When a pin is directly beneath the corresponding head, the wheel 4 of the head reaches a dip in the track. and the cup 55 is depressed, thus forcing the edge of the cap past the ring 65 situated below the capping-cone 66. The bottles are conveyed through the machine by a conveyer composed of three-wheeled trucks 70 travelling on tracks 72. Sprocket-chain links 73 depending from the tracks engage sprocket teeth 74 on the outside of the sleeve 85 and transmit motion thereto. Standards 86 on the sleeve 85 carry the plate 87 which supports the filling- apparatus.

Title: Automatic transfer oscillator with fm tolerance
IPC: H03B21/00
Filed: 1974-02-01
Abstract: 1423802 Automatic frequency control; frequency measurement SYSTRON-DONNER CORP 1 Feb 1974 [14 Feb 1973] 4740/74 Headings H3A and H3H   A system for measuring the frequency of an r.f. signal at input 15 includes: (a) an a.f.c. loop, Fig. 2, comprising a harmonic mixer 12 fed with the r.f. signal and the output of a voltage controlled local oscillator 13 to produce an i.f. signal which is applied to a frequency discriminator 18 whose output controls the frequency of oscillator 13; and (b) a measuring circuit comprising means responsive to the r.f. and local oscillator signals for producing an output proportional to the harmonic number N at which the mixer is operating, and counting means responsive to this harmonic number output and a time base for concurrently counting the i.f. and local oscillator frequencies over a common time period determined by the harmonic number signal and the time base, the sum of the counts being indicative of the frequency of the r.f. signal. The a.f.c. loop includes a sweep oscillator 21 which sweeps the VCO 13 until the selected i.f. is obtained, and also a squelch circuit 24 coupled to the i.f. line to prevent generation of both upper and lower combinations of the multiplied local oscillator frequency and r.f. input. The frequency discriminator Fig. 3 (not shown) comprises a monostable circuit whose output is fed to an integrator and lowpass filters. In the frequency counting circuit, Fig. 4, the i.f. is counted by an up/down counter 36 over a period determined by the product of a predetermined time TB and the harmonic number N. This period is derived by dividing a frequency <SP>1</SP>/TB by N in divider 44 and feeding the divider output to a bi-stable 47 to produce a signal having a half period TB x N. This signal and the i.f. from the loop are fed to AND gate 37, the output from which is divided by N in divider 38 to give the actual i.f. During the period that counter 36 is counting, an accumulator 39 counts the local oscillator signal. The contents of the counter 36 are added to the accumulator 39 to provide the final r.f. count.

Title: Improvements in or relating to electrical power supply equipment including normal and standby sources
IPC: H02J9/06
Filed: 1947-02-19
Abstract: 631,342. Supply systems depending on two or more sources. STANDARD TELEPHONES & CABLES, Ltd., and KELLY, R. Feb. 19, 1947, No. 4842. [Class 38 (iv)] Standby supply arrangements for major and minor loads, which require different voltages and which are normally supplied from the A.C. mains through independent power packs, comprise a main stand-by generator adapted on failure of the mains to supply directly the major load and to energize a motor generator which then feeds the minor load. In the music open-wire broadcast power equipment shown, major loads requiring 130 volts and 24 volts and minor loads such as valves requiring heater and plate voltages of 6.3 and 220, respectively, are normally supplied from A.C. mains through rectifiers RC, P2 and P3, but the 24 and 130 volt supplies are maintained on failure of the mains by an automatically started engine driven set over change-over contacts CO1, CO2, batteries 24VSB and 130 VSB maintaining supply during change-over. Upon failure of any of the 220 volt supplies, due to mains failure or other causes, one or more of relays RF1-RF3 operate and energize from the 24 volt supply the motor M of a motor generator set MGS having a 90 volt generator G which, in series with the 130 volt source then supplies the 220 volt load. Upon generator G reaching a prescribed voltage a relay CTR changes over its contacts ctr1 so that the 6.3 volt heater load associated with the defective 220 volt supply is now supplied in series with the armature of motor M. A carbon pile voltage regulator CPR may operate on the generator or motor field of set MGS, or, particularly when the set MGS has a permanent magnet field, the pile may be included in a part of the motor circuit supplying heater current. Change back to normal supplies may be automatic or by operation of a manual switch. A switching arrangement may also be provided whereby any of the minor supplies may be shut down without causing the standby motor generator to start.

Title: Improvements in the construction of sound-boards for stringed musical instruments
IPC: G10D3/02
Filed: 1926-02-20
Abstract: 247,995. Lumiere, L. Feb. 21, 1925, [Convention date]. Pianofortes and other stringed instruments, soundboards and bridges for; violins. - The formation of nodal lines in vibrating soundboards of stringed instruments is avoided by constructing the soundboard with uniform resistance to the strains transmitted by the bridge, its thickness increasing from the edges to the point or points of support of the bridge in accordance with a hyperbolic law. In a violin as shown in Figs. 1 and 3, the hyperbolic curves of thickness h radiate from the left foot p of the bridge and have a common asymptote passing through that foot. The back is similarly formed, the right foot of the bridge being extended as at v and passing freely through the belly so as to rest on the back in the position of the common asymptote. The boards may be built up of superposed sheets, indicated by dotted lines in Figs. 1 and 7, glued together and arranged so that their edges lie in the hyperbolic curves. These sheets may have tongues t as shown in Fig. 7 to give a more continuous elastic reaction. The sound holes of the violin may be placed in the sides of the bouts. In the case of a mandolin, Fig. 8, where the whole of the base of the bridge contacts with the belly, the hyperbolic curves radiate only from the ends of the bridge, being arranged parallel from m' to m<9>. In a pianoforte soundboard, Fig. 12, the curves are arranged parallel, approximately at right angles to the bridge f, which is formed by the thickness of the board intervening between the ends of the pairs of curves and may varv in width. This soundboard may also be formed of sheets with serrated edges. A modification of the previous constructions consists in arranging edge on, on a board of uniform thickness, a number of hyperbolic strips h', either parallel and perpendicular to a bridge f as shown in Fig. 17, or radiating from a common asymptote.

Filed: 1943-03-30
Abstract: 573,178. Automatic gramophones. PAILLARD & CIE SOC. ANON, E. March 30, 1943, No. 5092. Convention date, Oct. 10, 1942. [Class 40 (ii)] In an automatic gramophone, means for detecting the size of the next record to be played so as to position the pick-up accordingly comprises a feeler member 28 carried on one of the rotary members 9 which serve to support the pile of records above the turntable, the feeler member carrying projections 31, 32 which engage the underside of the record through apertures in the support. At the end of playing a record, a shaft 8 makes one revolution and a pivoted slotted lever 14 is oscillated by eccentric pin 12 to control through a further pin 16 on a lever 17 the rotation of support 9 to release the next record. Lever 14 also has an opening 21 for reception of the pin 16 when it is desired to repeat a record as described in Specification 368,206. If the next record is of the larger size, projection 32 engages its lower face, Fig. 3, and during rotation of support 9, driving member 35 engages an arm 37 on a sleeve surrounding shaft 10 and a pin on the other end of the sleeve operates lever 41 to inove lever 42 to the dotted-line position. A pin 44 on lever 42 now rides on the outside of a cam 26 on shaft 8 and a pin 24 on an arm 23 secured to the pick-up shaft 22 rides on the inside of cam 26 to position the_ pick-up for a large-size record. When a small record is to be played, projection 32 passes through support 9 and projection 31 engages the lower face of the record. In this case, members 35, 37 do not engage, lever 42 remains in the full-line position, pin 44 rides on the inside of cam 26, and pin 24 is held by arm 42 away from cam 26 so that the pick-up is positioned for a smaller-size record. When the last record of a pile has been played, projection 31 also passes through support 9 and a member 50 engages arm 37 during the return movement of support 9 to release a catch 54, 55 controlling a motor switch 56 as described in Specification 573,179. The Specification as open to inspection under Sect. 91 refers also to (i) the provision of a second catch also controlling the operation of switch 56 and operated by the entrance of the pick-up into the last groove of a record, (ii) means associated with lever 17 to ensure the return of the pick-up to the first track of a record of either size when repeating a playing, and (iii) modifications in which the projections 31, 32 are carried on separate feeler members or the feeler member is in the form of a spring- controlled finger sliding in a groove and engaging the periphery of the record. This subjectmatter does not appear in the Specification as accepted.
